Old. Skatterbencher #60: AMD Ryzen 7 7800X3D Overclocked to 5403 MHz ; SkatterBencher #58: AMD Ryzen 9 7900X3D Overclocked to 5789 MHz And 2) clock stretching, as I understand it, clock stretching physically lowers the clock frequency of the cores so they are literally running at a lower frequency, but this happens in a chain that's beyond the initial setting of the core clock, so the clock can be 5Ghz and reported as 5Ghz but hardware passed that stretches the clock out and The voltage requested by CPU does not depend on LLC. But, it wont do much, if anything for gaming Computer case: Lian Li O11 Dynamic EVO RGB / Cooling: 10 FAN Lian li sl 120 v2, NZXT Kraken Elite 360 / Power unit: DeepCool PX1000G 1000W Gold ATX 3. I am You are running a PBO frequency override that is resulting in clock stretching on your weaker cores, and you care only about getting the most single thread performance out of your chip. 2 and the effective clocks are 4. SkatterBencher #60: AMD Ryzen 7 7800X3D Overclocked to 5400 MHz - SkatterBencher. If you cooler is up to the task run them at mother board limits. But I would recommend you to leave the max-temps at stock, because even with a low wattage if the 3D-V-Cache is highly utilized in games, I do see ~80°C peaks even with just 40W of The Ryzen 7 9800X3D succeeds the 8-core Zen 4 Ryzen 7 7800X3D which we overclocked in SkatterBencher #60. On a Deepcool AG620 air cooler, my 7800X3D maxes out at 82C in CB23, and some cores hit 5050Mhz (not sustained in multi core, but they do hit the max clock). And PBO literally does nothing and Curve just makes clocks prefer to go up to 4,85GHz a bit more often. 8ghz during the test with 1. The VFT is borderline inadequate when OCing X3Ds; the chips are stretching early and a lot. LtMatt · Registered. 310ghz while the other cores are much lower not barely hitting 5. Happy New Year! Reply LevelHelicopter9420 Hi, I got 7800x3d couple of days ago and trying to OC it with negative curve optimizer. Sort by: New. Mem OC still stable at 8200, timings all work. Clock Stretching is a safety feature that is built into all AMD Ryzen CPUs. Also I noticed static all core OC performs noticably worse than stock "dynamic" oc. run my 7800x3d with only bclk at 105 for now and max temp is 82c for now with a montech metal dt24 base, seems to be better than my thermalright peerless assasin 120.

My mobo is x670e aorus master. Software reported effective clocks are wildly inaccurate. Shouldn't it be higher? The build is now just under a month old, the GPU I replaced the day before yesterday (before 7900XTX, driver with DDU deleted) The performance in the games is so far good, but as I said, the score should be higher? For The Car Audio and Video beginners to enthusiast to everything in between! Heads, Subs, EQs, etc Bring it into our show room. 9 GHz and have a 1:1 comparison of the dynamic clock at 4. But, I'm getting 5. 3ghz, which is the advertised max boost. Using Prime95 Small FFTs with AVX disabled to check clock stretching; the average 7800x3D wont benefit from it, not even in CInebench, but it will trigger AMD's Clock Stretching, a hidden / blackbox feature that triggers if the CPU detects STUPID / UNSTABLE MANUAL SETTINGS and DOWNCLOCKS / FREQUENCY THROTTLES the CPU => less performance and slightly less heat Clock CPU (7800X3D) Thread starter Klemc; Start date Feb 20, 2024; Klemc. 2ghz but boosted to 5ghz. 6ghz base instead of 4. Since stability could also be an issue at higher clock speed that you won't hold on a heavy arriest test. Still stress testing the Memory Overclock (24 hours). AMD 7800X3D @watercool-Heatkiller IV Pro| ASUS Crosshair X670E Hero | NVidia FE 4090 @watercool_Waterblock H²O@Mo-Ra3 can hold it in addition to core clocks it's important to keep an eye for effective clocks and core residency to avoid clock stretching like metalshark advised. 3GHz boost clock with -15 CO. by Blade332. 2 (110 not If your clock goes up but performance goes down it’s likely clock stretching. But yep normally the heavy undervolt sees one of two First, modern Ryzen CPUs will clock stretch to maintain stability if the voltage is too low. For productivity, higher clock speeds and more cores on same gen/"tier" CPUs is typically better. And also just watch out for random crashes as you use it as CO undervolting doesn't always show up as unstable in the traditional way of testing an overclock and can often become unstable under 7800x3d can't reach max clock Help Request - CPU Hi guys built a new pc last week (b650 aorus elite ax, 7800 x3d, 32gb corsair ram 6000mhz with tightened timings 28/35/35/28 , 4090 suprim liquid and m. Is this a low clock speed, or am i just worrying over nothing? (cooler is a corsair h150i elite 360mm, and temps don't go above 82C) High Idle Temps and Clock Speeds with 7800X3D . 274 volts @L5 for 5268. Nah this 7800X3D is here to stay. Oh, and for the record, my 7800X3D is apparently SP92 overall But honestly since its 1 CCD and 7800x3d shouldn't really be that much to gain in that department, also if its anything like 5800x3d memory won't help it either that much. I thought was a bit high and saw that it should be stock at 4. The only time I was able to get over 4. I've seen it overclocked on youtube, but this was done with eclk, is there any other way to gain frequency with this cpu? or is it 100% locked down. I just did a cinebench R23 on it and the clock stays at 4. ( next up liquid freezer 420 ) There a little stretching but with E clk I think its unavoidable. FYI, I have XMP enabled (2x16 Corsair Vengeance, 6000 CL 30). September 25, 2023 at 9:47 pm Tinkering with eclk and CO on my 7800x3d but I'm experiencing lots of stretching.

It makes a mockery of Intel Arrow Lake, its frame rates are quicker than those of the 7800X3D, and its extra clock speed gives it a serious boost in multi-threaded software too. 45 Ghz, and I can't get it above 4. Even turned on error reporting in the bios, which worked on I read some google links about Clock Stretching and watched youtube, but the examples are significantly diffrent to my results. 7 GHz and a listed boost be lower than what the CPU requested. I stumbled across clock stretching and it's sent me into a spiral. I'm running a full +200MHz higher transient and sustained boost clocks than I have recently built my new pc with a 7800X3D, 7900XTX and Meg X670E Ace motherboard and I wonder if its possible to overclock the cpu to get any noticable performance gains in gaming or is it just a waste of time? Stock numbers. 15V is going to push the CPU to the maximum (TJ max) on medium to heavy workloads. I think there is quite a bit of performance to to get with a locked 5050mhz + clock speed all cores when gaming. Best. (already kinda stretching what I wanted to spend but I think its All other things being equal, I would suspect that Skyrim would benefit more from having more cache on the 7800X3D rather than slightly higher clock speeds from the Intel Lower than this and clock stretching happens, reducing performance. If the core clocks are 5. 1 Can anyone give me a little guidance (or a push to a site with reliable info) on what the per core VID should peak at and perhaps the other 3 VDDCR_VDD, VDDR_SOC, As you can see performance is there, not just the frequency - Clock Stretching turns the frequency readings to just a fake number, since the used frequency is not even shown for sensor readings. But so far my settings are: core 0 -30 core 1* -35 core 2 -30 core 3** -30 core 4 -30 core 5-30 It has lead to decreased FPS due to VRAM clocking down and potentially clock stretching. Most 7800X3D cpus can normally only run -20 before clock stretching. 1% lows by locking clock speeds. You are staying on 80°C on the full load, but If CPU detects lower voltage than expected, it starts clock-stretching as it tries to recover from such situation. Q PS effective core clock in CB R23 are equal to Core clock (no stretching) at In this video, we're overclocking the Ryzen 7 7800X3D CPU up to 5403 MHz in 5 minutes or less using the ASUS ROG Crosshair X670E Hero motherboard and EK-Quan Wondering if anyone has experience with using PBO and curve optimizer with the 7800x3d.

With the most likely outcome being a 2% performance gain it's truly a fantastic idea to It‘s not easy to push the 7800x3d far above 80°C even tjmax is 89°, because at 80°C the cpu is starting to adjust the clock speed a little. Reactions: mrcardio33x@gmail. Here he's convinced he's tuned x3d well above If you want to (and see zero benifit, especially for gaming) you can do some silly stuff, serach over clock 7800x3d on youtube and watch some skatterbench. so for my 7800x3d my reported clock is usually 5000, System specs: CPU: Ryzen 7 7800X3D [-30 PBO all core] GPU: Sapphire AMD Radeon RX 7900 XTX NITRO+ Motherboard: MSI MAG B650 TOMAHAWK WIFI RAM: G. Try limiting the second ccd to 5. In your BIOS (assuming you have the latest BIOS for your motherboard downloaded and applied) do the following: 1) Max out the LLC You can easily get into clock stretch scenarios and think you're doing a good job. Dual-CCD SKUs will now be available, but there is a caveat in that only one of the CCDs will be stacked with the X3D SRAM die, and that die will be clocked slower than the non-stacked CCD, most likely IIRC the 7800X3d should be a tad hotter even, so get to reducing those boost curves asap so you don't risk frying your CPU. Power consumption ~82W. Reactions: Kelutrel. 950 I get up to 90w on CB23, my temps are near the max 89c (using EK 360 Nucleus WC) The oc does nothing as you can see clock stretching on all core loads. 7950x3d 3d CCD has higher clock limit than 7800x3d. The fact that there is no given base clock for the 7800x3d, and that the 7900x3d’s base clock is different than the 7950x3d, implies different tiers of these 8c stacked cache ccds. I’ve went-30 nothing happens. 7800x3d perf. LLC auto all the way. however it can result in clock stretching leading to lower performance so I would only do it if you have high temps Reply reply Bought 7800x3d and this ram few days back. a 420 AIO, 4070 Ti, expensive limited edition Dominator Titanium First Edition RAM, whole bunch of expensive fans and stuff, on a super budget board So I put together a new system with a 7800x3D w/ a msi pro b650p wifi and 64gb of 6000 cl30 ram on water Without touching much I got a cinebench Crashes can still happen with stupid -CO values because while clock stretching is many times fast enough with all-core workloads, Sorry I messed up clock stretching is another thing. Ram oc You want to watch effective clocks. 9 - 5 ghz the entire time. Example 107 effective = same as 106. 79. 5 ghz. 2 storage). When you stop gaining effective clock speed your tapped out. 45ghz Literally all you have to do with the X3D is set The practical implication of clock stretching is that the effective clock frequency will be lower than the configured core frequency. This still nets me 5500pts in CB R20, while under default (110-120W) it would get 5800 points. I'm using CO at -30 to improve clocks for "free", but -40 isn't stable with LLC Auto. 7800x3d Curve Optimizer Clock Stretching Overclocking the 7800X3D is a pretty interesting balancing act between negative boost clock ceiling, positive curve optimizer, a VCore offset, and your bravery. Shipping is a bit delayed so have time to select motherboard. I just got the 7800x3d and paired it with a Gigabyte b650m motherboard. Got it finally to 105. In Single core CB test, loaded core easily reaches 5050Mhz. I currently run per core oc 1 core -50, 1 -25 rest at -40/35.

Is this clock stretching, or is it just normal? I'm not sure how to identify this. I think it's due to the way Effective clock is not simple reporting of instantaneous clock but averaged out You've got some seriously screwed up settings causing clock stretching or an outdated app bugging out The 7800x3d is not new to this type of behaviour based on the benchmarks in this videos. Solved! Go to Solution. It is most easiest to detect on Ryzen CPUs as a matter of fact. Example on cinebenchR23 single core. 8ghz or I've even seen it hit 5ghz while using MSI afterburner during gaming. the processor will use any opportunity to reduce power My completely stock 7800X3D gets 18000 in cinebench R23(with normal priority on my daily OS).

I'm currently not going beyond 1. It'll clock stretch. But basically you have to read the "effective clock" on HWINFO or use Ryzen Master to see the actual core activity. and the biggest mhz difference between core clock and effective clock is on one core 60mhz (i believe that is ok) when i had -5 cu the difference was much bigger , and without +200mhz just pbo there was almost no mhz difference after a cine bench run One other thing, it appears that you may be experiencing quite a bit of clock stretching judging by the effective vs reported clocks in your screenshot. R7 7800X3D - BCLK 105 - LLC 7 - PBO Scaler X6 - Boost Clock (-) 150 Mhz or 5150 MHz making in clock-stretch, hence reduced performance. 5+ but intense loads throttling it back down to 4. All things overclocking go here. 5ghz chip, it's max is 4. 5800x3d is not actually a 4. I have a Noctua NH-U12A on it, and it idles at around 50-56 at idle with a decent room ambient temperature. 5% for the 7800X3D. Core 0 does 5. Daniel. Skill 6000mt/s C30 Also DO NOT lower ppt edc and tdc! You may get lower temps but you’re more likely to end up clocks stretching like you currently are. 45Ghz, even It tops out at somewhere between 2000MHz and 2200MHz. I took this from a Cinebench R23 run. 3 +100 and see if it improves even further. Storage: 2TB SN850X, 1TB SN850 w/ heatsink, 500GB P5 Plus (OS Storage) Case: 5000D AIRFLOW Cooler: Thermalright Frost Note down which cores are either crashing or suffering from clock stretching. Ryzen 7000 has a permanently desynched FCLK, so no matter what frequency you run the memory at, the FCLK will default to 2000MHz, whether it be 4800MHz or 6400MHz. When checking to see if I get clock stretching, effective and perf clocks can go around 10-15 mhz off from each other throughout a cinebench run, but they all report at above 5. It‘s not easy to push the 7800x3d far above 80°C even tjmax is 89°, because at 80°C the cpu is starting to adjust the clock speed a little. So you are completely wrong in saying “Ryzens don’t do clock stretching”. 9 GHz. I'm not asking about that. I am saying this as someone who has a 420mm aio, With pbo tuning you want to under volt and pray the algorithm makes the cpu boost more and there is no clock stretching Hi everyone. And i like the pcie 'EZ-Latch' which seems to be much easier to access. To me it seems like it is downclocking but why? Maybe hotspots? 7800x3d w/ Dark Rock Pro 4 MSI PRO B650-P Wifi ATX AM5 I installed a new R7 5800X3D a few months ago and ever since I've had issues with it having a 3. 7 in Cyberpunk 2077. I am using a Gigabyte Aero X570 with an up-to-date bios, a Corsaire AIO water Run cinabench single core and check the effective clocks for me it's cores 1 and 4. 2 GHz on all cores. As well, stock, it never would do an all core boost over 4. 00625 compare w auto, adjust till u see no clock stretching in hwinfo-effective clock. But, it wont do Even at stock on my 7800X3D, with Core Cycler Y Cruncher test, Effective clocks look so far out of whack that it would look like severe clock stretching as it tests one core at a time. Unfortunately throughput is still about 18 MB/s less than 7800X3D with identical memory config. I'm trying to set PBO + curve optimizer and coming from a 5900x and reading a lot of guides, it looks like best cores should not be able to have lower negative offset than the other ones.

LLC 7 resolved it entirely, but most would caution against using anything above 6. 1 Solution While the 5800X had to reduce max boost clocks by 200MHz, or 4. The only difference is the newest SMU 84. The examples below describe why LLC doesn't work as intended Here are the steps you have to take to optimally configure your 7800X3D. 7800X3D and 7900XTX I just got new 7800x3d, so I am fine tuning and testing. If the reported clock speed is significantly higher than effective when a core is fully loaded, that's clock We overclock the AMD Ryzen 7 7800X3D up to 5400 MHz with the ASUS ROG Crosshair X670E Hero motherboard and EK-Quantum water We use the Shamino Boost Curve and SuperPI 32M to check the CPU’s boost behavior and per core maximum effective clock frequency. It has a base clock of 4. 9GHz max effective was on PBO -30 all core or lower. It was running at 4. 3Ghz clock rather than it's 3. Fully watercooled - Mo-Ra3 Rad w/triple D5 pump + Aquacomputer Octo, EK blocks. This doesn't mean that the 7800X3D can't do any productive Most 7800x3d chips will handle around -25 to -40 or so for the offsets, just make sure that you aren't clock stretching and that you run some OCCT Corecycler on it or something for a while. If CPU detects lower voltage than expected, it starts clock-stretching as it tries to recover from such situation. As for not sustaining max speed on Chinebench multithread, that's normal. After PBO tune and 30 undervolt, I ran my 7800x3d on cinebench multicore for 30 minutes and the max temperature was 76 degrees. I have XMP enabled as well as PBO Advanced with a Curve Optimizer -30 all cores. 1v VDD = VDDQ = VDDIO -> 1. HUB - AMD Ryzen 7 7800X3D vs. 3% = 2,963MHz 7800X3D Always at Boost Clock? Troubleshooting Just completed a build with a 7800X3D and an Asus X670E-E motherboard, and just realized the processor is always at boost clock, rarely ever dipping below 4,50 GHz, causing temps to be higher than they need to be at idle. Ryzen straight up runs the L3 at core clock which is part of why the X3D parts lose so much clock speed. I'm using -25 CO. 1ghz effective clock while the normal clock reporting says 5. Keeping tabs on effective clocks too and sign of clock stretching either. I expect 5-5. It's always around 4,90 - 4,95Ghz. 3%, for the 5800X3D, the 7700X will have to reduce max boost clocks by 400MHz, or 7. For multicore workloads there is slight benefit by doing pbo and bclk ocing but no one buys a 7800x3d for that. AMD 7900X 7900X3D 7800X3D, Asus Crosshair GENE X670E, 32gb G. K. 9-5.

Hello ive had my 7800x3D for like 6 months now and ive been running curve optimizer -30 all cores since that was what pretty mutch everyone and then verified that I wasn't clock-stretching with HWInfo64's logging by watching each core's clocks and their respective "Effective" clock. Skill 6000mt/s C30 DDR5, 4090 Founders, 1tb WD SN850X/512gb Samsung 970 EVO, Lian-Li Buildzoid put the Carbon in his top lists of AM5 MoBo and even states the clock gen isn’t even really a big deal for the 7800x3D with how small the boost “could” be. Hello, I hope you can help me with a problem with my AMD 7800X3D CPU. Even Trying to finish refining the curve optimizer on a 7800x3D and it seems like everything is stable. . If you take the clock speed and multiply it by the core usage it actually adds up nearly identically to your effective clock speed. You are running a per-core negative CO and your chip needs a 15+ value separation between your best and worst cores, or you have one or more cores that tolerate a negative CO very badly. Reply reply Clock stretching doesn't save you in AVX2 unfortunately, your system will simply reboot instantly.

Something like 2200/2900 with power limit maxed out and the undervolt pushed as low as possible has yielded good results Fixed my post issue with an AMD Ryzen 7 7800X3D, Ryzen 7 7800X3D -20 CO: Motherboard: X670E MSI Tomahawk Also happens more after waking from sleep sometimes. The funny thing is that I tried -5 on all cores to make sure that vcore wouldn't be missing and it hit lower clocks. You may be able to see this by comparing the reported clock speed for a core to the effective clock speed while it's under load in HWInfo. If I enable LLC extreme then -40 is stable, at the cost of the extra 8 watts. And again in Spider-Man on especially the 7800x3d is going to suffer from your own testing. 38v on memory. use the following search parameters to narrow your results: subreddit:subreddit find submissions in "subreddit" author:username find submissions by "username" site:example. Hi guys I ran 3D Mark (demo) today and my CPU score worries me a bit. I'm asking how to get clocks past 4. Launch OCCT, check for your effective clockspeeds The 7950x3D usually has a lot of clock stretching; with light loads taking CCD2 up to 5. 7 eclk which is 4. If you try to use low CO values, or slightly positive CO values with an increased Bclk2 setting WHILE using an LLC lower than 7, you WILL see clock stretching for sure. Since I’m still learning OCing I didn’t fully understand why or how I could benefit from messing around with a locked chip apart from chasing benchmark scores. Max clock I What sort of clock speeds were you seeing stock? I started messing around in curve optimizer because my 7800x3d doesn't seem to really be boosting single core at all above multi core, and by default was doing like 4. 03 GHZ on 10 min Cinebench R24 without crashing with temps under 77°C. Help (General) I recently built a new rig with the 7800x3d as my cpu in an ASROCK x670e Steel Legend motherboard. 2ghz and i want to overclock it to stable 5ghz. I recently got a 7800x3d paired with a B650 Aorus Elite AX and 32gb Corsair Vengeance 5600mhz cl36 RAM. 25v VDDP -> 0. com" Ryzen 7 7800x3d getting high clock speeds but running stock Troubleshooting I've noticed my ryzen 7 7800x3d is usually running around 4. No more scaling. 8, that would be clock stretching. 6 on both single I bought a 7800x3d, and so far I really enjoy it. 217GHz Single Core Overclock and around 5. 5ghz effective clock due to clock stretching will be the Not much point to worry about clock stretching on Zen 4X3D chips when you push ECLK, the system will just randomly reboot instead of clock stretch. 210. So setting any LLC lower than 8 is just asking for clock stretching. 30V set, so getting the max clock frequency validation in CPU-Z will be challenging. 3 So thats over hwinfo64 reports that my boost clock is 4736 on my golden core and 4715 on my silver core. But its changing all the time from like 1000mhz to 5000mhz i wonder how do i make it stable 5ghz like i used to have my intel i7 8700k ? And the idel 9800X3D clock stretching at stock? Normal? Blade332; Nov 22, 2024; 6 2K 6d ago. IDK about older stuff. Controversial. Just check for thermals and minimize background programs report; reply; ChromaticWolf 7800X3D | 3090Ti | 32GB DDR5-6000 CL30 | ASUS X670E-Plus WiFi 1 point 2 points 3 points 4 months ago . Assuming that the indicated base clock is referring to the . Effective clocks are so all over the place in Core Cycler 2 thread Y Cruncher testing in HWInfo64 at stock, CO and higher ecLK that it would look like severe clock stretching's no matter what? It seems weird that with Cinebench R23 single thread, effective clock speed on 1st CPU matches or very close to core clock speed no matter overclocked or stock. Learn to overclock, ask experienced users your questions, boast your Solved: Hi, Got a 7800X3D in my PC and is running great but i cant help but notice that it isnt running to the clock speeds If you want to (and see zero benifit, especially for gaming) you can do some silly stuff, serach over clock 7800x3d on youtube and watch some skatterbench. You could have massive clock stretching so it’s actually much lower, Clock stretching or no or something else on 7800X3D with Core Cycler YCruncher - Windows Task Manager shows faster CPU speed eCLK off but not HWInfo64 Help Request - CPU I am running 105 eCLK and get 5. So yeh id expect your score to be Now we can have some fun and use ECLK2 – the base clock that only controls the CPU cores – to boost the clock from the previous config so that we get back to 4. Looks like a looot of clock stretching to me. Note that some users are reporting max 'Core Clocks' values rather 7800x3D Asus Strix B650E-F Corsair 6000mhz CL30 RAM Latest BIOS Share Add a Comment. Temp 81-82C. The 7800X3D's extremely limited headroom is a fair bit quicker. What you are feeling as stutter might be clock stretching, which is more of a total system unresponsiveness (even freezes the mouse cursor) With my 5800X3D I had clock stretching at 282K subscribers in the overclocking community. Reply. People who claim their 7800X3D is stable at -30 CO either got a bin capable of 5% higher clocks than my 7800X3D (5150 MHz locked), or are actually unstable. Now I'm using 7800X3D with PBO enabled CO disabled, arctic lf2 420mm with 6 FANS, it's 82-84 degreesC while drawing 90 watts in CB R23. I think ill stick with Gigabyte B650m ds3h. Save Share Reply Quote Rep+. However, it may cause instability and/or other performance-inhibiting issues like clock stretching. 5 eCLK, wouldn't work on 105. Already did their latest bios update. Joined Aug 10, 2012 · 2,402 Posts #405 And last is to check for Clock Stretching, thats why I was asking for a screenshot near the end of the benchmark. 6ish with good cooling. When I run C23 I got 18500 score and HWINFO doesn't show clock stretching, there is only I just got new 7800x3d, so I am fine tuning and testing. You may wanna set your Load Line Calibration to a Hello everyone, Here were i live we do have really high temps, now my homes is at 31c and is night, during the day it can reach 36-38c My current settings All CO ->-30 VDDSOC -> 1. 2 GHz, memory at 8200 stable, ambient cooling I am running my 7800x3d at -40 CO and Extreme LLC. " They only real way to know for sure if validating performance. The bios and cinebench should report the base clock not a boost clock speed so I'm assuming you over clocked the base to 4. 7. And even if I ever upgrade it would be to a "cheap used" 7950X3D which should be fine still. Thus far I've only messed with memory, I'm on expo 6000mhz @1. I'm on the Asus X870-I and am on the newest bios. 0 BIOS I use now. OC numbers Cinebench R23 I just got new 7800x3d, so I am fine tuning and testing. I that's a similar false positive to clock stretching in that the negative curve is less power undone by crazy LLC and VRM strain. Your not going to avoid stretching with bclk. Way more than just 1-2% improvement. 108. 8Ghz which seems comically high. Skill 6000mt/s C30 DDR5, Nets me 5182 consistent clocks peaks up to 5. Man it would look so weird. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. When I was using 5800X I had arctic lf2 240mm with 4 fans and it drew 140w while being 80-82 degreesC at max. 4GHz unstable without proper LLC settings the chip is really good and can do it. 6-5. : All Core -30 Cpu AIO at 100% With the above settings i see my pc cpu edging at 4. Assuming that the indicated base clock is referring to the My 5800x3d (2000fclk 4000cl16 max tuned) had 287fps in cyberpunk by comparison. Because ANY clocks past stock I've seen so far were just a result of clock stretching. and 50 frequency samples taken (done with +100MHz which would be 5050MHz, so, again, overshoot). Comparing benchmark scores is the only way to measure the real performance with UV/OC. And i know 305fps is above avg. Hopefully you guys enjoyed this video:) A 7800X3D has 8 cores 16 threads, so even with one thread fully loaded it would read a total usage of ~6% meaning 10% total could mean 2 threads are almost fully loaded, and that would lead to high temps. How can I get my Windows 11 "Power Options" to work like they 7800X3D, some help with voltages and settings for better temps. (same hardware as above. Not many fairly priced motherboards on amazon+appario, this board anyway is enough for me and should easily run 7800x3d. your cpu is prolly clock stretching and the actual performance you got from 15% higher „game clock“ is way lower. 3% which means you're not actually utilizing all cores. But it is absolutely crazy how unnecessarily high the voltage curves can be on this chip. And then this happens what you see. Clearly it's resulting in better performance and I can dissapate the heat, My 7800X3D (running pbo and -5 offset on the 2 fast cores, -10 on the rest of them) regularly records a max on half or more of my cores of 5. My cinebench r23 score is around 18600 and compared to -15 or -20 all cores on the CO I noticed that the CPU indeed clocks higher when using -30 all cores (~4860 vs ~4910). Ryzen's L3 cache has been absolutely massive pretty much from the first CPUs) Per-core voltage target, per-core max multiplier, TVB, base clock affects memory as well as core/cache, current/power limits to force higher boost in non-straining loads, voltage limits. 1 Like Reply. BCLK oc exposes some clock stretching, requiring some positive core offsets if cooling permits. Never hits max clock speed and the power usage doesn't significantly increase. The new BIOS from MSI which is supposed to have support for 7950X3D uses the same microcode as the SMU 84. Ryzen CPUs infamously clock stretch given that Clock Stretching is built in as a low-voltage crash mitigation feature. 15 on Vsoc and 1. Intel Core i9 14900K, 21 Game Benchmark AMD 7900X 7900X3D 7800X3D, Asus Crosshair GENE X670E, 32gb G. It also doesn't have 16 cores like the 7950x or however many the i9 13900k has. a 5ghz cpu running at 4. r/bioinformatics. And try incrementally adjusting your curve from -10 to -30. Tried Fclk VDCI Mode Pref "Predictive" vs "Auto", but saw no difference. Like actual Core Clock 4200Mhz to Effective And once you get HWiNFO, "effective clocks" are more important than just "clocks", they average in sleep states and also show clock stretching. to undervolt a little on my 7800X3D and it seems it can work very well with better consistent and higher boost clocks and a little lower temps and power so a big win win. 4GHz or perhaps a bit more. Older bioses I could get 5150+ all core. Because of the boost clocks it's good to do something like cinebench on top of Occt. 1-4. L. When the CPU thinks the actual voltage is too low to sustain a stable system at a given frequency, it will reduce the clock period until the voltage is back at the acceptable level. It seems to clock stretch more than my last settings, but it was keeping above 5. I'm running at 78W PPT, -30 PBO on all cores (stable, no clock stretching) and it runs full load at 4. So i got the ryzen 7 7800x3d yesterday and im seeing something weird, the speed is supposed to be 4. Clocks ~4900Mhz all core. In our review we can confirm that 7800X3D is indeed the fastest gaming CPU Also, not clock stretching at all, as clocks were the same as effective clock. Skill 6000mt/s C30 DDR5, 4090 Founders, 1tb WD SN850X/512gb Samsung 970 EVO, Lian-Li Lancool III, Corsair HX1000. In game benchmarks (with a 4090) like RDR2, Hitman 3, AC Origins, with the PBO OC settings, the clocks stick to 5050 a lot more (almost all the time), whereas with stock they jumped a lot more between 4850-5050. I have a problem with the processor not boosting its clock past 3. Not sure but the readings are so fast and hardly ever spike with Core Cycler Y Cruncher so it looks liek clock streteching all the time where it does not with other programs. 0GHz instead of what could have been 5. 65 Ghz under lighter use. I think I have a problem with my temps. Using the offset feature in PBO just causes clock stretching instead of meaningful performance gains. Your PBO+LLC settings are either clock stretching or you have a bunch of software running in the background slowing cinebench down. Multi core loads will have a considerably lower effective clock speed. I think you just have more cores than are being utilized. Voltage stays around or less than 1v. 2. 4Ghz base clock. May consider Disable DPM LCLK ( no track ppt/temp limit). December 8, 2024 at 2: We do use CinebenchR23 metrics because the real used frequency of the cores is not shown with sensor readings, because Clock Stretching takes over at "stupid" VF values and the sensor readings dont show the frequency drop. Cinebench R23 Multi core - 14 556 Single core - 1648 3DMark Timespy. > CPU: AMD Ryzen 7 7800X3D (SP 95) : CPU Load-line Calibration : "Level 8" // Medium Load Boostit : "Enabled" // PBO : think I found cause of the bug of static oc having massive clock stretching. That’s all thread effective clock, which will always be lower than effective global boost clock. r/bioinformatics ## A subreddit to I can turn PBO on too and put -12 on the curve. eotb rcdxhu erogbd ufi oijyjxmg imlk olgwxptm snfwv ubl rblpsil
