At the moment on a 5900x, I needed to even set a positive 5 count steps on one of my cores to pass a certain prime95 workload. 4v then Undervolting would get you around 83ish watts (this is just rough math) and a maybe quite a nice drop on the temps. After reading through the comments on While gaming (Warzone, Halo, WoW) temps are 55c-65c and Voltage is consistently 1. You should have it as long as you have the latest BIOS for your motherboard installed. my 5600x uses -26 CO with +50mv offset voltage thus running 4000mhz 2000fclk super tuned timings c16 flat T2 cmd rate, WHEA free for well since Your best cores need higher voltage, your worst cores can handle much less (-30 or lower offset often). Setting the voltage to 1. I can fold for weeks at 4600 1. Also, the best you could hope for overclocking the 5900x is just cranking up the TDP and dropping the core voltage offset (which takes a while to dial in properly). Can I just set the CPU voltage offset to -0. But i'm kinda confused on what the Maximum voltages are for the Ryzen 5000 series. 42 or more for temperature. 7Ghz, but it is constantly getting 1. 8GHz) PPT/TDC/EDC values to they're appropriately limiting for the thermal factors you're trying to maintain, and not 5900x voltage spike 1. 1V: 26137 I also did some tests restricting the number of threads to 4 (most of the games I play only use 3-4 AMD's Ryzen 9 5950X and Ryzen 9 5900X delivers crushing performance in nearly every single workload. Along with the AMD Ryzen 9 5900X processor and GIGABYTE X570S Aorus Master motherboard, in this guide, we will be using a pair of Aorus RGB DDR4-4400 memory sticks, an NVIDIA RTX 2080TI graphics card, an 512GB Aorus RGB M. After noticing this I started to dig around in order to understand what could be wrong, I went back to the Asus AI Suite, noticed the wrong voltage and set it back to Hey guys I got myself a 5900x and been playing around with it quite a bit. Thermal Grizzly AM5 Offset Mounting Kit, Thermal Grizzly Extreme Paste: Motherboard: ASRock B650 LiveMixer (BIOS/UEFI version P3. Max Safe Voltage for ryzen 3600X. The real problem is just that the 5900x has 6 cores per die and is not that great of a gaming chip, so I’m not sure if an extra hundred MHz or two is gonna help that much. Set i bios CPU Voltage to 1. These are BIOS settings. Hi guys, I'm using PBO2 to increase the performance of my 5900x. I'd like to say im also completely lost as to how to overclock a 5900x. Final offsets were as follows. Finally, I read some random comment in a thread recommending undervolting using the offset, instead of through curve optimizer. Coolers software gives a lot of information one of which is vcore voltage. On a CPU like yours (or my 5900X) this cant be over 25W max. Reply reply -Aeryn- • • Watch frequencies during the test runs and you'll see that at the same frequency as before the offset, it uses less voltage. The boost algorithm is temperature seeking so it will always try to reach the same temperature but with an undervolt it hits same temperature at higher clock frequencies. You should look into using curve optimizer and seeing how much of a negative offset you can put on each core without losing performance . The voltage offset is adaptive, meaning the processor will use its own understanding of its voltage and frequency As I said before, these settings fix that and make the 5900x run great . However, because the architecture doesn't clock well, AMD has to use a shit ton of voltage to get those cores to hit those speeds. 950V/1. drea. 35V maximum voltage for long-term overclocks, and although the company says Ryzen can withstand 1. From there, I apply offset voltage (on the VF point curve or the overall core offset) to get it where it needs to be. I ended up leaving the BIOS settings on automatic and found out the issue was the MSI Dragon CPU: AMD Ryzen 9 5900X Cooling: Arctic Liquid Freezer II 360 AiO Thermal Paste: Arctic MX-5 Case: Lian Li O11 DYNAMIC Mobo: MSI X570 Tomahawk, BIOS Version 1. 7GHz up to 4. This is the first time I am using AMD ecosystem. CPU VCORE 1. Here are 5900X - Voltage. 950GHz peak single core) (And 3. 4v and after applying the settings the cpu temps skyrocks to 90ºc. AMD folks seem to know what they are doing with EDC. In order to improve single-threaded or lightly threaded performance, one or two cores are placed in the die that can achieve significantly higher clock speeds. I don't even have one core that can take -30, let alone 12. step 2) CPU LLC 2 and VDDSOC LLC 2. 352 Offset: Override+offset (-. These next settings are what I use to get better single and light threaded performance for games, so not the best for Cinebench but still worth I just got the Ryzen 5900x, and I dont know if this behaviour should be normal. Ryzen 9 5900x Gskill Tridentz 3600 CL16 (DCOP enabled) 3090 Strix Share Sort by: Best. Go from there. 65GHz at what was actually 1. PPT 1000W, TDC 600A and EDC 155A with all cores on -30 curve offset (except for the 5th core, that ones on -24) and +200MHz Boost Override. 47V) even on a very minimum work load. 35 tops. Ok, I have about 5°C lower temps (at idle & full load) than you, with cheaper CPU cooler (on 5900X). 3v to the core voltage. My 5900X would run -25 all core curve at lower voltages then stock but still with full 4. 7ghz, ccd 2 at 4. 18V and clocks are somewhere around 4GHz. thanks TLDR; if you are having random system crashes / freezes, increase your SOC voltage offset by +0. 550 V (HWMonitor) which scared me, I went searching around and found that offset voltage thingy. 95GHz (same frequency) So the all core setting actually results in a downclock at the same time which is why it likely doesn't AMD recommends a 1. same BIOS, and for some reason straight undervolting doesn't work (offset voltage doesn't change anything). I have seen some youtube videos, I dont want to overclock, just reduce the offset a little bit. Of course this depends on the CPU scheduling that happens to take place on your OS. If you're staying with manual overclock, higher LLC lets you keep the voltage down. In turn using AMD overclock + offset settings all on auto and setting manual multiplier to 45 does keep volts at a constant 1. I'd keep at at 1. Reply reply [deleted] 23k in R23 is quite easy to achieve, that is my score. New posts. Using any sort of voltage manipulation locks my cpu to stock 3. 3 or 1. 75s. The voltage offset is adaptive, meaning the processor will use its own understanding of its voltage and frequency If I set the SoC voltage to "Auto" then the mainboard will set the SoC voltage to 1. 000 and the "VDDG IOC" voltage to 1. 45000] 5900x on EK Velocity copper, Dark Hero, 6900xt on alpacool block, RM 850x, G. Is this normal? i know that Robert from AMD, has said that the safe voltage is up to 1. 5900x X570 TUF Pro (4021 BIOS, so AGESA 1. 05V on my R9 3900X and it drops about 10*C during those spikes with 360mm AIO. 015 Offset by -0,1v this should limit the voltage to around 1. 40 instead of like 1. I've noticed that most of the time, even in IDLE, I have a voltage between 1. B-dies can stand up to 2. Don't mess with gear down mode unless you wanna spend the next few hours ryzen 5 3600 static voltage after OC with OFFSET voltage upvotes X570 Boost for 5900x with Voltage Offset upvotes I'm currently using 5900X, but this guide will be suitable for the other 5000 series cpus nevertheless. My 5900x goes on Max voltage (1. 325V and reccomended to use some mid levels of load line calibrations, because of voltage spikes, on Asus that's Level 3. problem is pc going into black screen und Your best cores need higher voltage, your worst cores can handle much less (-30 or lower offset often). 05 - 0. It runs stable doing CPU intensive things like prime95 or compiling with gcc, but when I do very light work loads, I get MCE errors. 45V, longevity may be affected. I also used to keep my 5900X undervolted on my C8F for the same reasons, thermals and a slightly higher top performance in MT. but>" To get the most accurate answer to the question about the limit, I decided to measure it myself, on processors based on the Zen+ and Zen 2 architecture. 28V CPU Load Line Calibration on Level 3 CPU Vrm Switching Frequency to max CPU Power Duty Control on Extreme Have you already used curve optimizer to give a negative voltage offset? That noticeably impacted my boosting behavior in games, letting the CPU boost to 4. I had to slightly increase the voltage. 5900X under boost load all core is closer to 230w. It is always around 1. May 5, 2021 #4 GabeFromNewJerz said: I am new to overclocking. I keep reading that 1. This is about all I'm going to have as I am not familiar with your bios. The VDD telemetry offset effects the maximum all core frequency achievable dependant on the load that is being requested. You can Does this voltage seem to high for 5800x all core workload on stock settings Menu. 3 & 4. I am currently rocking an ASUS Dark Hero X570 and a Ryzen 5900x (rest of build specs below). Setting a vcore offset for instance, combined with increased LLC settings will provide lower temperatures and lower highest voltage, but will Also, the best you could hope for overclocking the 5900x is just cranking up the TDP and dropping the core voltage offset (which takes a while to dial in properly). Multi remains the same and I didn’t notice any improvement on temps My concern is that a negative voltage offset could impact the performance of Ryzen 9 5900X (July 2022), 220W PPT limit, 80C temp limit, CO -6-14, +50MHz (up to 5. If I set the SoC voltage to "Auto" then the mainboard will set the SoC voltage to 1. 95GHz much more frequently. CPU VDD Telemetry Offset Value: 25mA 20mA. I recently got an 5900X kai Asus ROG Strix gaming F mobo (Coming from i7 4790 with low tdp and nothing to worry about with air cooler ). 2v is highest i should go, while others say 1. I'm a bit confused because two of the key settings (I think) seem to be contradictory, being the curve optimizer offset (from 0 to negative 30) or the manual OC boost limit (from 0 to +200 mhz). And how long did you run it so hot at 90C. Reactions: gwynbleidd997. Dec 3, 2022 #17 Also, if it's the CPU offset voltage that's responsible for the power/heat improvements, I have similar problem since i bought this cpu 2 years ago. 2 (beta) Shortly after I got it Arctic released the AMD Offset Bracket which supposedly helped for Ryzen 3000 & 5000 CPUs. 1v or 0. I actually had an issue that my CPU would not go below 1. Reference voltage: 1100 mV Reference frequency: 4300 MHz Recomended values for overclocking (P2 profile): Reference I also used to keep my 5900X undervolted on my C8F for the same reasons, thermals and a slightly higher top performance in MT. 336V/1. It’s a pretty handy MSI didn't instruct me to turn PBO back on, they nudged me to try the voltage offset. It is a beast of a CPU, a lot of coolers cant handle 5900X imo. 4 V and started increasing clocks, while checking stability at the same time. 3 Patch C) G. I know the only real program for monitoring temps on AMD cpu is AMD Ryzen master, all the others lie for couple degrees(3-4c). Just leave it on auto SOC, 1800 Fclock, do 3600Mhz which is what you have and tighten the timings because increasing SOC voltage also increases heat and stress on your CPU. 45~1. What is the same recommended core voltage to stay under for daily use on zen3? I have an Asus Dark hero motherboard and plenty of cooling. I use -0. 49V and clocks around 3. . 3 volts, Because of the potential risks of using extremely high voltages, we advise staying within these limits to minimize long Yeah voltage may very based on the lottery. Open comment sort options. Jul 26, 2022 #3 Alvesss154 said: In fact, I’d say my 5800x at -30 all core is more stable than my 5900x at -5 all core. after i changed my graphics card the problem occured again. Curve Optimizer will start with a larger offset at lower loads to reduce power usage and reduce the offset at higher loads to allow higher You shouldn't need to touch the voltage at all. I use Corsair AIO's with my 5800X and 5900X. CPU VDD Full Scale Current: 170A 180A. 6% +2. If I set the boost limit to +200, I'm unable to use a lower (more negative) My 5900x seemed okay on a -30 PBO offset. I'm currently using 5900X, but this guide will be suitable for the other 5000 series cpus nevertheless. All Cores will allow you to undervolt each core at the same negative offset. 4. 0125V Cinebench R23 1650 single core and 23800 multi core. Reply reply more replies More replies More replies More replies More replies More replies I've noticed that with PBO enabled (I only have PBO and not curve optimizer in my BIOS), the larger the negative voltage offset, the better the multi-core performance becomes. Also your cinebench score is fine, don't worry about it. filinux. You can reduce this by setting a negative offset voltage. TLDR: The system slowly and progressively became more unstable, disabling PBO and adding a +0. my 5600x uses -26 CO with +50mv offset voltage thus running 4000mhz 2000fclk super tuned timings c16 flat T2 cmd rate, WHEA free for well since I've settled at -23 offset for daily use. 5900X / ASUS X570 Dark Hero with latest bios / Windows 11 with latest updates and chipset drivers installed / All stock expect the XMP profile. 84/day) Why do you need the over voltage?

Tried everything from setting LLC to level 2, disabling C states, positive voltage offset. A direct core voltage offset kind of works but not all the time, at least not to the extent I would expect. 49v. Then after wards I added offset to cores (core 0 and 2) until no longer stable (At one point core 0 (1) was at -10 offset). net, set to detect CO errors). DRAM Voltage: Raising the RAM voltage can help Manually Changing voltage - clock set to 4. I've stress tested the memory, CPU, and GPU. Best cores were -5, and -10. 55 maximum voltage (not at these screens, but i have seen this). 385-1. 8mhz I actually run an offset, the voltage by default on Asus boards gives the 5900x too much. 2% Offset mode adds a specific amount of voltage to the processor regardless of the frequency, while Adaptive as for why I did the offset because I read this. FYI: all of this is moot without stable RAM. 5V, though I have since read that it's fine for it to do this, as it only 5900x overclocking & voltage tips. 075. Am I missing something? I'm just curious. hi i was wondering can you use CO and the voltage offset at the same time and is it actually safe to use voltage offset all the time and will it degrade my CPU since its kind of similar to changing voltage manually similar to manual OC. 3x140mm case-front fans, 6x140mm on the AIO, cranked to 100% for the benchmark run, in 72f temps. This cannot affect really CPU temp. But if I put a negative offset of -0. voltage in the bios doesn't matter, but the voltage your CPU gets under full load does. It just keeps boosting no matter what i set in, untill it hits the 70-80ºC range. The sensor you are looking for in hwinfo is "Core voltage SVI2". You can increase DRAM/VDIMM voltage to 1. In theory, at least, the curve optimizer should be *more* stable, because it can adapt. Yes, it's manual voltage offset and/or core VID. 65GHz depending on load with 165W max power draw. I did the UV with Rayzen Master because if something goes wrong, the BIOS will restart with Don't use Voltage Offset, use the Curve Optimizer. Help Request - CPU Trying to lock in a stable daily OC on my 5900x. 1. That being said, running it like that doesn't help much on the apps and games that I use. 2 NVMe SSD, a Seasonic Prime 850W Platinum power supply, the ElmorLabs Easy Fan Controller, and EK-Quantum Apart for cooling, voltage management is most important and various BIOS versions tend to set it on a high side (in the name of stability), introducing negative voltage offset can help a lot. 05V. 7 GHz base clock and a 4. 7GHZ (not sure the voltage, but cpu-z can tell you) = 105w I want to undervolt my 5900x. Hyperx 3600. 75GHz on all cores with an input of 1. You can set the voltage offset to 0. its not undervolting, you are just changing the voltage curve. My idle temps are always around 35 - 40C. If power current and temps were not an issue you wouldn't need the curve optimizer offset to reduce voltage and realize greater frequency gains within the electrical and thermal envelope of the system. 2GHz or so on all cores. Your results are very interesting to see; it shows diminishing returns. Reply. 85GHz (some lower frequency) Curve Optimizer -0. 25-1. I had to enter the BIOS and decrease the voltage offset on every core until stable. 0 - temp is ok, i'm not playing atm only anydesk to work. When I built this I had an issue with CPU temps due to the cpu getting 1. I pretty much just hit the OC button on the gigabyte software and let it do its thing, but every time I reboot the system resets itself to I'm running 5900X on a MSI MPG X570 Gaming Plus paired with 32GB (4X8) 3200 16-18-18-38 Gskill. more so needing consistent voltage even under lower load situations. My SoC power typically fluctuates between 14~15 up to 20~21W depending task/load, and I'm running 1. Check my With that in mind: I've read that some people have had luck actually raising voltage slightly with offsets and then raising PPT and TDC limits a bit to push the CPU harder under Nice do some stress testing and monitor temps and voltages. 05v to hit 1. 7GHz all core at 1. Which Is it normal for some cores on a 5900X to require a positive offset in curve optimizer? I initially set all cores to -15 and all other settings left alone. On my 5900X I run 240/160/190 all core -25 is what I daily with. 2v in cinebench with load temps around 56c. The safe voltage for the Ryzen 5900x is between 1. 00/4ghz without a no-post. But when it is under load, the voltage drops down to 1. 500v). That said 1. I tried all the way to voltage offset to -0. Running Pop os 21. Below that, Curve Optimizer Control will already be Included with Auto Offset turned on. (Default bios settings except for -0. Averaging almost 10C lower in Warzone and framerates are very similar. 030V on an otherwise completely stock default bios. 125v. I'm using PPT 160 / TDC The right way to undervolt with a 5900X is using curve optimizer, not by just lowering core voltage. PBO on PBO override 200 MHz DDR4 XMP 3600 and overclock to 3733 My Board, an MSI X570 MEG Ace will only function correctly using the "AMD Overclocking" voltage setting with an Auto offset Quick search for 5900X suggests this this. 5V near constantly even with no load. 45V @ 4. This is extremely easy because of AMD Ryzen Master, My 5900X has an undervolt using Curve Optimiser per-core, stock power limits, and no 'AutoOC' or additional frequency. 45v and PBO is enabled, however the CPU comes out of the box. 2% / +12. For the voltage, when the available modes are set to 1. Motherboard seems shit, PSU needed replacing, as did the case. Discussion Evening!

Reply reply 5900X going over 1. 2 with the two cores at -0 and everything seems fine. Tested with Powersupply Idle Control set to Typical Current Idle and it still doesn't accept much negative curve offset, but at least I got my two best cores to -10 and -5 offsets and I'll leave it at that. Got my Just scored 23,567mc -10 all core CO on the Ryzen 9 5900x never went past 69c during the 30-minute throttle test in Cinebench r23 no undervolting no extra mhz found my PBO2 limits scaler on auto posted it on Reddit Nervous King no undervolting scaler left on auto no extra mhz. 3375, they'll be: (HWINFO64) Override: 1. Zach_01. 8 GHz boost clock. That time i solved problem by changing offset voltage and used system without a problem for 2 years. 5 . 4v at all times, causing 60c+ at idle, and the moment I turned on a game it would shoot to 80c+ and get worse. The CB23 scores are below: All threads: Stock: 25390 Offset -0. I manage to do it in 37. 0), BIOS F39b, AGESA V2 1. Sometimes you just need a bit more voltage during idle to keep it stable. The best scores were sitting there with a frequency of 5Ghz. 1v. 318V in BIOS, translating to a My 5900x voltage is kept at near 1. Both come near 1. I noticed that with curve optimizer my best cores boost up to 4950. 5V 4. Setting a vcore offset for instance, combined with increased LLC settings will provide lower temperatures and lower highest voltage, but will However, what does concern me is the voltage for single core. I'm already on a 3080 GPU, so I feel like I'm going to be good there for a while. Same board worked fine with my 3800x. 05 but my 2 cores that couldn't handle -30 couldn't handle a voltage offset, so I reduced them from -20 to -15 and the voltage offset was good. The CPU was going up to just below 1. Oct 29, 2022 #3 pendragon1 Extremely [H] Joined Oct 7, 2000 Messages 58,968. 5 V indicated is 1. 43V @ 4. It will not increase your voltage or temp by much Offset by -0,1v this should limit the voltage to around 1. 075V: 26056 Offset -0. so it should lower all voltages up to that amount. 27v (which would prolong my CPU's lifespan as My 5900X for Linpack and static OC, 4500MHz at 1. 1) but I cannot find that offset thing anywhere in my bios. 325-1. Reproduction of the issue is sit and wait on low loads, ie: Chrome (doing anything), TLDR; if you are having random system crashes / freezes, increase your SOC voltage offset by +0. 95GHz All-core -0. So during the test it has more power available, and the chip advances to higher frequency steps. 05 offset, and set boost clock override to +50 and cpu is stable Voltage: To get right into it, I'm admittedly a bit frustrated. like this. This gave me higher SC scores. Solved: Mainboard: MSI x570 Unify Mainboard-BIOS: 7C35vA82 (Beta version) CPU: Ryzen 5900x RAM: Crucial Ballistix BL2K32G36C16U4B 3600 MHz, 64GB (32GB x2) Browse AMD Community. But one core seems to require a positive offset (core 1, the second-best CCD0 core after core 0). C: Leave voltage on auto, PBO on auto or raise PBO limits and boost override if you want a more oomph. Mobo is a gigabyte x570 pro with a 5900x on it. After noticing this I started to dig around in order to understand what could be wrong, I went back to the Asus AI Suite, noticed the wrong voltage and set it back to So I tried to set a voltage offset to -0. When I'm not gaming the vids are usually 0. 1D2 CPU: Ryzen 5900x Cooler: Artic Liquid Freezer II 280 with 4 fans in push-pull. 8. Whereas, with a constant undervolt, My 5900x, 1 of the best cores does not like more than -10, the other best core on the other CCX will only do -15, every single other core will do -25 and -30, Im still playing with it. Default settings my 5900X will top out a little below 1. View solution in original post. So for example, Stock: Core 1 runs at 1. You can't set both if you wanted to use the Is there a way to limit max frequency/max voltage while still allowing PBO to run in ryzen 5900x? I am looking to reduce the max temps (also looking at idle temps when AGESA 1. They The right way to undervolt with a 5900X is using curve optimizer, not by just lowering core voltage. And its my first time using a AMD CPU since 2008. 6-3. This isn't much of an improvement to the below so I may switch back to 4. D. So I tried to set a voltage offset to -0. and surprisingly I have got it stable at a massive all core negative curve optimizer of -30 in addition to that I am perfectly stable with an offset of 0. I have a 5900x. But when I do this in the Bios MSI, I start PPT: 220W, TDC: 200A, EDC: 170A. 5900X PBO Advanced (220W/140A/140A) - Single core 4. About 140 watt under a all core load This is my 3900x Cranked up I hit 187 watts of power draw on the CPU I got around to trying an offset voltage. I've recently got a 5900x. Oct 26, 2017 18,143. Ryzen Master and HWINFO64 shows different readings on idle. The 5900x is a pretty tame chip (compared to 5800x) since heat is spread through 2ccd instead of 1. applying 1. 35v. 05 // ~90W The 'clock + voltage' have better score and better thermals than the PBO curve while only losing only in single core performance. Recently I upgrade from 3900X to 5900X and found that in SMU options it is no longer possible to limit the Precision Boost max voltage to 1. For example if you set Vcore "offset, - , Auto" and Max Voltage offset to "0. Also it's normal for it to go up to 90C, I think the thermal limit for the 5900x is *90 degrees C so if it goes above that then you have a problem, but zen chips will take the CPU: AMD Ryzen 9 5900X The curve optimizer employs a variable voltage offset, based on the voltage/frequency curve, hence the name, whereas with VDDCR, you're applying a constant offset across the entire range of frequencies. The results show that full reliability for AMD Ryzen Threadripper 2990WX and other 12 nm processors is at 1. 5V and stay there when idling. 9688 and the "VDDG IOC" is set to 0. 975 the ZenTimings tool is showing me that the SoC voltage is set to 0. The alternative is to increase the voltage offset to raise the minimum Vcore, which would still allow the PC to throttle itself when required but achieve better low-end stability. Thank you My System: I cant find anywhere what are stock 5900x voltages and I'm not sure how to set them. 3V even when idling (My CPU was 60C when CPU usage was 1%). MSI didn't instruct me to turn PBO back on, they nudged me to try the voltage offset. Did the voltage get very high under load. Hello, I have read a lot of people saying that is ideal to enable pbo in bios and undervolt (offset -0. Override + offset (offset in auto mode?) Similar situation is with memory. Offset is now -0. Manufacturer says that stock voltage is 1. It has a core/few cores constantly running at 4Ghz+ and the others at 3. My 5900x is at 180 ppt 180 edc and 125 tdc and I'm at 1650ish single 23000ish in cinebench23 Reply CPU voltage offset + 0. Things I have already tried. It's best to use a dynamic voltage curve that changes with Best way i to use and apply negative Voltage offset in BIOS, typically -0. Reducing it gets temps in control. 26-1. C: Cooling: and lastly the Curve Optimizer which allows you to set a negative voltage offset (in millivolts) for each core (a good starting point for all is -5mv and work your way up after you Let’s find out what is voltage offset ryzen CPUs, in order to get a better understanding of this topic. If you want to be bold, try -0,11 or -0,12. 1%: Core i5-12600K DDR4/ DDR5 +15. 1 Like Reply. When ever I run a memory-intensive task like a compile job or stress testing with Prime95 or Linpack, the system would just turn off after a while - although the reported temperatures were always OK. Using HWinfo to read CPU Core VID (Effective) and CPU Core Voltage (SVI2 TFN). 1v + that offset, and also locks my 5900x to 3. 65 multi core boost. CO does reduce voltage, but with the intent to increase As you have found out, using a manual voltage offset in the CPU Core Voltage section of the BIOS is not really the way to go. Not even using negative offset. rather than using offset you can use pbo2 and then if you want offset voltage, you can bring It more down setting the fit scalar to x0 on pbo2tuner app. Package Power Tracking (PPT): 142W 5950x, 5900x and 5800x and 88W for 5600x. If your values are correct, 90W*1. Browse designed to be part of the normal operation of these CPUs (disable CPB and global C states in BIOSor add a positive offset to some/all of the curve optimiser values). 2) AMD Ryzen R9 5900X: In particular, you don't touch this unless you have ram going past 3600Mhz and the Fclock needs more voltage to match 1/2 of the RAM frequency. Like Like Setting low values reduces the voltage applied which gives more power/voltage headroom so the frequency increases with little to no extra power usage.
