Per core curve optimizer. My 3950x and my 5950x both spike to 1.

Per core curve optimizer This lets you adjust each core separately for better results. Allcore Curve Optimizer -> [ Per Core ] 体制最佳核心维持All Cores时的Negative值，别的核心继续优化，跑CB R23 多核心，如遇宕机 Win10开始 -> 事件查看器 -> 自定义视图 -> 创 select all core or per-core and click the curve optimiser button it will prompt you for the maximum offset and the maximum is +/- 50 but at default its 30. First, note that the per-core curve I have Ryzen 9 7950X3D (I am new to OC) is it a bad idea to go Curve Optimizer "All Cores" only or should I go "Per Core"? Do you have any procedure, how to find the best settings Per Core Vcore offset moves the entire curve up / down. That's nearly as good as a manual OC, I can literally It's only better if you want to do the tedious task of testing each core for its instability point. Tested in -10 increments, Precision Boost Overdrive 2. Just keep the 버미어의 기본 CPU 부스트 클럭 기능인 PB2의 전압을 CO(Curve Optimizer)를 통해 조정 후 보증된 클럭 이상으로 작동하게 만드는 일종의 오버클럭 기능인데요. Choose an offset. I found the videos below helpful. I love I am tuned to a negative per core Curve Optimizer lol. 294 mensajes 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 Curve Optimizer lets you tune the VF-curve per core or all cores in BIOS With the latest AGESA for this platform there's a new option hiding in the AMD Overclocking menu. First download the latest BIOS for your motherboard and flash it. I got around 4. I suspect the instability might be related to power transients when different cores use different offsets. I haven't had any Technically you cn do the per core optimization through Ryzen Master, though I have that come out not stable in the past so your mileage may vary. PDifolco; 1 Link to AUTO OC + PER CORE CURVE 5600x RYZEN MASTER Overclocking I'm looking to use Ryzen Master to get the most out of my 5600x, I am willing to go into my BIOS as well. Slap the start optimizing button. The whole reason for the offset is to prevent the crash on idle. 2v All CCD1 cores will still push past 5. and curve optimizer set to -20 all core. is better (but more tedious) that you set 1 thread and apply to only one thread of the Later for longterm testing: Curve Optimizer per-core stability test tool (Curve Optimizer per-core stability test tool : Amd (reddit. I Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. 32GB of ram 4 dimms OCed to 3800 cl16 1:1 with relatively tight secondary timings My CPU's best cores are Core 0 and 1 in CCD 0, Core 6 After finishing the CO Optimizer, it set all my cores to -20, but once again, it bricked my system after restarting it, thanks Ryzen Master! I was really curious to see what is bricking it, so I went Hi there guys, just an small post to gather some curve optimizer negative offsets on your AMD Ryzen 5000 series. Ryzen R7 5700X | B550 Gaming X | 2x16GB G. It's Curve Optimizer defaults to Off. Under PBO, leave the scalar at I ran the per core optimizer and have run my system on -30 on all cores with no problem for a few weeks now. Consider my 7th core, for example: it's stable at 4800 MHz 1. You have to select either All Cores or Per Core first, then Apply. Core 8, core 10 and core 13 can't even handle -5 without bluescreening within 1-3 minutes of windows idling/doing minor tasks. 006V step offsets from base curve basically. I've settled at -23 offset for daily use. . Wollen wir das Maximum erreichen „Per Core“, was sehr viel Arbeit bedeuten kann. To put it succinctly: Curve Optimizer overclocks your CPU. 0, agesa 1. For this guide, I wanted to rely on the OCCT toolkit to find the right Curve Optimizer settings. Maybe I got lucky or something? I was Curve optimiser is a tool to allow you to tell the processor to use a lower voltage than standard at any given clock speed and allows you to choose this per core, per ccd or for the entire processor. Then, I verify the stability in all-core multi-threaded workloads. 155v during all-core workloads, using curve optimizer and a 102 BCLK. May I ask? Why the under-volting?? You have temps some people dream. 0 enhances AMD Ryzen 5000 / 7000 desktop series of processors with all-core / per-core undervolting feature called Curve Optimize How good is ryzenmaster at finding curve optimizer values per core ? I just ran mine and it set -30 on each and every single core, i was assuming that few cores would only do -20 or -25 or For me the curve optimizer suggested values that core cycler found errors on all cores. It ran much cooler, remained in the 70s under load, but it crashed pretty quick Ryzen Master resulted -30 on all cores when I tried the Curve Optimizer selecting per core. 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. But why is it 16cores, that is confusing. the setting is per core but mode on left side show all cores. Per Core modunu dediğiniz gibi yaptım -25'e ayarladım apply dedim ama Ryzen Master tekrar açıldı başlangıçta ve Curve Optimizer Mode: All Core olarak gözüküyor neden I wouldn't start right now with a per core curve optimizer, go with a all core soft curve optimizer, start with -5; -10 or -15 all core and check stability, voltages, performance and 「Curve Optimizer」を選択する。 「Curve Optimizer」では、コアの設定とコア電圧の設定が行える。コアの設定は「All Cores」と「Per Core」のふたつが選択可能だが、 Passed 8h per core CoreCycler tests (Stability testing), and a few TestMem5 runs while ocing RAM. Ryzen 7 9800X3D Curve Optimizer Tuning Process The manual tuning process for Curve Optimizer Hello everyone! The AMD APU Tuning Utility team have recently released a build of AATU (found here) that allows the manipulation of the V/F curve for 5900HX CPUs, in a similar fashion to I recently bought a ryzen 7800x3d with a Gigabyte Gaming X AX mobo. "Heavy" and "HeavyShort" are recommended in the "Curve Optimizer Guide Ryzen 5000" for stress testing. My 3950x and my 5950x both spike to 1. I had a Ryzen 5600x which would crash the PC when set at -10 all core. 204V offset (min selection) on the BIOS. Para cada core: Negative y '15'. After I adjusted the curve optimiser for each core and turned wow OP thanks for this! I tested the curve optimizer tool in there and it worked on my 5800x3d. 75ghz anything above would I’ve been doing per core curve optimization on my 7950X3D for a few weeks total since ownership. come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, The advanced mode of RM CO window showed "Curve Optimizer Mode" as "All Cores. How can i switch ryzen master Got my 5600x yesterday and immediately went to the bios to work on the curve optimizer. g. To as adviced by wNotyarD, ive manualy set Just to try it out I punched in your values (but without the per-core Curve Optimiser values - I put in -15 for all the cores as I forgot which are my top cores). Jump to Latest It has to pass core cycler on stock settings, moderate w/AVX and 2 threads (1 hour per core) and heavy (1 I believe AMD could improve Curve Optimizer by letting us set a per-core MHz limit. It should be per physical core only, not logical cores. Wir . It's too bad PBO2 doesn't have a per-core MHz limit, because it seems like raising the curve primarily Many people have been able to run even larger negative offsets on Zen 2 series processors since their release, although usually with reduced performance being a result. Curve Optimizer can be configured per-core Negative Curve Optimizer value, on its own, is not considered as an undervolt because CPU Curve optimiser is very hard to get stable at idle without per core tuning which takes ages and most chips except the 5800x3D won’t be stable or have any meaningful improvement. Yup. I now find myself in a crash loop with Windows 11 where it can't. So I stayed with core cycler stable values, much more conservatives than Ryzen Master. I've built a new PC and ran the Ryzen Master application to do a per core curve optimisation. Curve Optimizer lets you tune the VF-curve per core or all cores in BIOS With the latest AGESA for this platform there's a new option hiding in the AMD Overclocking menu. Lately I've been toying up with PBO2 with my 5600X. Arctic Liquid Freezer ii 420mm on the way, will start maybe pushing things some more once installed However Gigabyte recently released a beta BIOS for my board that enables curve optimizer for the 5800X3D and it got me interested in testing some undervolts. Core cycler failed immediately. 2. Currently running curve optimizer with 5600x these settings-23-13-7-22-26-25 0 mhz AMD has updated Ryzen Master to include the curve optimizer directly within the app and provides support for the Ryzen 7 5800X3D and Threadripper Pro 5000WX CPU Curve Opmitizer를 Per core 혹은 All core로 할 수 있는데, 귀찮으시면 All core로, 나는 성능을 다 끌어올리겠다 면 Per Core로 하시면 됩니다. Also update Then it was time to dive into the Curve Optimizer menu, which has two settings: Per Core or All Cores. Started to play around with PBO. Skill 3200 CL14 @ 3600 CL14-15-14-28 2T / Asus B550 phantom itx - curve optimizer per core option not showing cores. No clue why AMD would introduce this feature honestly; your best cores will barely be able to go above -10 or even -5. When it loaded back up Usually, I spend a lot of time on per-core curve optimization. Event log showed event 41 i believe, I 哔哩哔哩 (゜-゜)つロ 干杯~-bilibili Could that mean that undervolting with curve optimizer is poinless to set on per-core basis? Because if I can only undervolt the top one or two cores by -5 and the crappy ones Then, I narrow down the per-core curve optimizer settings to achieve stability in a light workload. The nature of how curve optimizer works means that you are more likely to have instability when your system is idle In per core curve optimizer menu i see 16 cores listed, core0 to core15. resetting it to off fixes the BSOD crashes. I will show you the BIOS configuration in a minute. I’m currently recalibrating all cores because I updated BIOS and can Current Setting: I am currently running my Ryzen 7950X on 105w eco mode on Bios with -20 on All Core with curve optimizer. Lastly, I run when i create the curve per core i can choose per core and reboot. i couldnt set First time i ran curve optimizer not sure on how stable it actually is at super light loads and variable loads as well as high loads, it set all my cores to -30 when i set per core, and im This is because curve optimizer is applying a static offset to the final voltage the cpu runs on. 5Ghz at 1. Ryzen Master will try different settings to find the best one for I'm currently able to maintain an all-core boost speed of over 5. It's Am I doing something wrong with the Curve Optimizer? I selected Per Core, let the optimizing do its thing and then I clicked apply which forced a restart. In ideal world the curve optimizer should be applying close to zero / zero offset to the heavy For the Curve Optimizer Control, choose Per Core mode. Best tunes comes with default settings and scalar off. By combining vcore offset and curve optimizer, you can really fine tune things like super low idle voltage (lower than -30 CO allows) and at the I'm not doing all core myself as I couldn't go as low as I wanted to do in doing per core. Then it will run and Hydra optimizes per core curves. Here’s my broad I set my curve optimizer to "per core" and changed all of them to negative -25 to start off, and switched power limits to "motherboard" which of course maxes every limit out. 55ghz all core if I remmember. 38V, but unstable at 4825 MHz regardless of I have been tweaking my curve optimizer settings for months and I have several cores running at -30 with most at -28. Click Start Optimizing to begin the process. You can find Corecycler here https: Set Curve Optimizer to -25 on all cores - how stable this will be is entirely dependent on silicon lottery, Ran both per core and all core curve optimizer in Ryzen Master and both came back -30 for all and per core. I ran it at stock powerlimits with AGESA 1. If you get errors on a core, bring up the offset by +5 then run it again. it is german text. 5v on idle, it's definitely After adjusting the curve optimizer per core, along with PBO, I was able to get 8950 multi and 646 single in r20. Core voltage offset applies to all cores. I have 32GB Curve Optimizerには3つの設定項目がある。1番上は適用範囲（All Coresか、Per Coreか）、2番目は電圧を上げるか下げるか、3番目はどの程度を目標にする Use OCCT to get the core priorities, I then got the per core coefficients from CTR2. EDIT: Repetición de Cinebench tras valores por defecto. Configuring for all cores is the lazy but faster and easier way while configuring per core is the better and more このCurve OptimizerはRyzen全コアに対し一括で適用できるが、コア単位(Per Core)でCurve Optimizer の設定値を変えられる。手間としては後者の方が圧倒的に増えるが Ryzen Curve Optimizer (CO) stability over time. I have never ever had a crash because of boost I could not achieve -30 so I have curve optimizer, lower PPT values plus undervolting to keep the CPU cool. 0's diagnostic test. Am Are the Per-Core Curve Optimizer values cumulative? Are they added to the All Core values? e. AMD Ryzen 9 5900X / 4x16 GB G. Fortunately, thru reading this forum, I was able to figure Hey, wanted to know if its safe to use positive value for curve optimizer for best cores. Open the All core curve optimizer is a complete trap. If my all-core curve Optimizer is -15, and i set -5 for Core 1, is Core 1 The long, many hour method of per-core Curve Optimizer which is starting with a baseline of say -30 across all cores then running core cycler in Windows to find which cores Hi Mister, I get the BSOD after I have used the curve optimizer mode for all cores or per core. It's Now this is odd, my Core 5 managed to fail in safe mode within 4 iterations of prime95, 10minute per core. I'm not sure if I managed to win the silicon lottery or if I'm not stress testing properly. bromutu 16 dic 2020 20:19 * MegaAdicto!!! 3. OP's All Core Curve Optimizer works as intended and runs stable a Negative 25, but 30 can't run Y-cruncher benchmark. And even then, what you can get with all-core curve optimizer may not be too Test curve at auto voltage. All Cores. eg, for my best core, 20 - 14 = 6 try You have to set Curve Optimiser to per core, give Core 0 a zero CO magnitude and retest. /r/AMD is community run and In Curve Optimizer, start with an all core undervolt of -5. Is that good or bad? I see a lot of people posting they can't do any offset and Using curve optimizer I gained a huge bump in performance across all games. Some of my cores are stable at -25 and -15, others I had to raise all the way to -0. SEE BELOW. Browse Hi, when i create the curve per core i can choose per core and reboot. Testing to see how well it works but the estimated time start to finish is a little over an hour 😐 Then I deactivated the CO in Curve Optimizer - negative 15 (all cores) Max Boost Clock Override - 200 MHz Thermal Throttle Limit - 90°C (I've never actually reached 90, even with the default 95) Advanced PBO Limits The Asus Crosshair line got the new Bios Update and AGESA version Combo V2PI 1208 enabling Core optimizer by default. How can i switch ryzen master Curve optimizer is good but it's tedious to find which cores have issues but this helps and doesn't gimp you SC performance like CTR if it thinks your CPU can't handle more. 더불어 CPU 온도 역시 80도선에서 유지가 되고 -28 on core 0,1 -23 on core 2 to 5 -26 on core 6,7 -23 on core 8 to 11 Took 8 iterations of CoreCycler on the best cores. My best core needs -16. Over 640 is now common. I was even able to bump up the resolution across all games. CO의 방식에는 All Dialing in per-core curve optimizer settings can be tricky. Also few tweaks to make this faster. Help Request - CPU currently running a core cycler thats about to be done. Keep doing this until you're not returning errors. I have negative 10 on cores 0-4 and negative 35 on cores 5-11. If one One or the other. 3 on a B2 5950X and the per core auto curve optimizer values were very low. Takes 1-2 hours to go through each core individually Reply reply Now need to tune Curve Optimizer to the max stable, add boost and balance clocks to Unfortunately such an all-core stress test with Prime95 is not effective for testing Curve Optimizer settings, because the cores cannot boost as high if all of them are stres tested, and therefore you won't be able to detect so far i used Curve Optimizer in per core mode, today i tried all cores mode and results were even worse, -45 offset on all cores. I was also been able to lower the CPU voltage up to -0. I don't think tuning curve optimizer on a single core basis is a great method for finding a stable curve. If stable, go -21 if unstable go at -19. com)) Chapter III – Preparation. Das ist der einfachere Weg. 08v vSoC 1. How can i switch ryzen master This will constantly cycle the core through power stages to test for instability, and will report errors by each core. 7Ghz and the max temp while rendering on DaVinci Resolve weirdly, the main culprit for me is the second ccd. I managed to do Curve Optimizer will tweak the voltage/frequency curve so that the processor can run at a higher frequency at the same voltage. With these settings it will test all the v/f in both single and multi core. The steps for using Curve Optimizer to OC are: Curve Optimizer is part of PBO 2. Has anyone here actually tried to use the Per Core option for the Curve Optimizer to dial in precise undervolts for each core? Are there any tricks for judging stability or figuring out which Curve optimizer basically allows you to undervolt each core independently. If 1) Curve optimiser is offset for curve V/F for CPU, and specifically per core voltage Curve Optimiser value is multiple of 0. i have cinebench r23, occt, and corecycler to help dial in this undervolt i'm With the recent release of AATU's Curve Optimizer offset tool, I decided to spend some time doing an analysis on the relationship between power draw, thermals, at 25W and while it started fine in Cinebench R23 multi-core it eventually Ryzen master: All core or per core? Help Request - CPU I am just wanting a bit of a boost to my cpu and I was wondering if in Ryzen masters basic view, should I choose the per core or all Note: about a month ago when I started adjusting the curve optimizer I could hit -30 all core but nowhere near on the per core method. -30 is stable enough for benching but not for when i create the curve per core i can choose per core and reboot. I then subtracted the coefficient value from 20. I'm also just learning how to use curve optimizer. I need to If you want, you can start doing it again per core but start at -30 and repeat the process. Remember the good temperatures? The more headroom Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. Go back to BIOS and enter the Precision Boost menu, then set the Curve Optimizer to So I've undervolted with PBO in the bios, setting all cores negative curve with a value of 25 in the Curve Optimizer Magnitude field; Now I'm on 84C running a MC Cinebench R23, with a score Tests needed to properly validate per core PBO are described in the "guide". Bit deeper Wasn’t aware that there was an auto curve optimizer until now. 0, so enable PBO and set it to your platform's limits. Currently testing -15 all core CO and my temps dropped by nearly 5-10C in Cinebench! Of course have to really test more if it's actually stable. I have a ryzen 5600x in a b550 phantom gaming itx board (bios 2. If I select "per core" in the curve optimizer settings, nothing happens. I had the • 找到相应核心后，进入 BIOS，在 Curve Optimizer 修改为 Per Core（单核心） • 最后针对核心以 2 为单位，一次递减，直到成功稳定系统。 超频 微星主板 5900x 锐龙5000 pbo2 cppc Decided tested curve like these 0-0-0-0-0-0-0-28 etc every core but cpu sha3 not getting bsod, then i decided increase curve by 1 in last core (7) and test cpu sha3 and overall i passed 100 This is a thread to continue the escapades from this thread of my, and anyone else's efforts to undervolt their CPU with a PBO curve, to achieve equal or better performance Back to Curve Optimizer: Per Core. You can adjust performance parameters for the active cores, integrated graphics frequency and adjust memory timings. 0 and wanted to play around with the per core curve optimizer. Rejoice! Since the 5800X3D does not boost so high i saw many Curve Optimizer defaults to Off. Since benchmark results are quite low wrt to the average results I see online, together with core clock, I tried some Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. With the 7800X3D vs the 7950X that I have, the main difference is that with the 7800X3D the single core boost frequency equals the max all core frequency, meaning, there is So in this scenario, when you have a large discrepancy in the undervolting margin (curve optimizer magnitude) capabilities between the different cores, having only a single option I just updated my B550 Steel Legend to AGESA 1. Most people seem to stick with CO and even at a per core level. Curve Curve optimization per core all negative Core1 14 circle Core2 20 Core3 14 star Core4 20 Core5 20 Core5 20 Core7 20 Core8 20 Core9 20 Core10 8 circle Core11 15 Core12 8 star These In my case, I used a per-core Curve Optimizer ranging from -40 on Core 6 to -15 on Core 2 and a Fmax boost override of +150 MHz. Skill 3600 | Radeon RX 7900XT I have spent many hours trying to stabilize "per core curve optimizer" to no avail. When done with it work on core voltage For the core voltage, you can use offset or manual, I prefer manual for more Curve Optimizer all core -6 vCore Offset -0. 2v VDDIO MC 1. I tried to determine my best cores at I lost the silicon lottery and got a 5950x with a dodgy core (#6) which, if left at defaults, will idle-reboot the machine. 0. Set small data set, SSE, variable load, and set affinity to the core you're testing in Task Manager (mark both Usually your 'best core' and 'second best core' as shown by Ryzen Master will need to have less negative curve applied, and the rest of the cores can have less voltage (so higher negative Set the CPU affinity and test each core individually. My setup: Ryzen 7 7800X3D AsRock If you skip per core part, you might get micro stuttering in games when one of the cores keep "falling" because it is undervolted too much. (I already tested the others at -23 before) Took 10min of CB23 Curve optimizer - Per core. It is a journey. Tried to isolate and find the weaker core(s) but the per core The reason you do curve optimizer is because at stock from factory, AMD has a specific V/F curve that basically fits all cores, despite some being better than others, and by using per core you Curve optimizer tuned per core with corecycler. /r/AMD is community run and Also, I could not go beyond a negative 10 all-core offset with curve optimizer. And single is well 4. ) You can now go into per core undervolting to find which when i create the curve per core i can choose per core and reboot. I tried a quick and dirty all-core -18 and I noticed some instability (mainly in Hogwarts Legacy but also in Genshin) so I decided to try 라이젠마스터 자동 curve optimizer 방법(pbo2) 09-03; 저도 게임 실사중에 몇일만에 이벤트뷰어 whea 18 오류발생하였고, 이벤트 로그에 apic 4번으로 떠서 본문에 내용 I may have ended up on the short end of the silicon lottery, my 7700X will not accept -30 All cores, it even acted up a Tad at -25 all cores. How can i switch ryzen master Soll es schneller gehen wählen wir „All Cores“. You can optimize for general performance or fine tune the settings for your favorite applications. 0). " Is this not correct? Your CB scores look like R23, right? If you do not get a response to Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. I than set it at -15 on the 2 preferred cores, -20 on the With the 7800X3D vs the 7950X that I have, the main difference is that with the 7800X3D the single core boost frequency equals the max all core frequency, meaning, there is The best way would be to use per core curve optimisior. Going through them one by one: 5950x per core curve optimizer help . 46-1. AMD suggested that we might have better success hitting higher clocks Discussion on the effectiveness of Ryzen Curve Optimizer per core. Lol take time do it right run the per core curve optimizer in ryzen master with pbo on . As soon as I tried -15, I would get reboots In my experience, it's the two best cores that don't undervolt very far. Maybe it's geared towards 实质就是利用AMD新增的“ curve optimizer ”这一选项进行超频。“curve optimizer”能够调节pbo电压对应频率的的曲线,在PBO自动电压的基础上降低CPU电压，以避免CPU在高频运行时由于温 Set core cycler to to 1m per core set boost clock overwrite 25mhz more than your target once everything is stable roll back 25mhz and you are all set Reply reply No-Nefariousness956 • • Upon completion, review the final curve optimizer values listed in the Log, screenshot or note the values. Everything seems stable, in Curve Optimizer is available on a per CPU, per CCD, and per Core basis. It is Mainly did per core stress test since on all core it wouldn t reach such high frequencies anyway. my 5800x So, the “trouble” with the curve optimizer is that you can spend an infinite amount of time trying for more optimization, and the gains get progressively smaller. Iterate between STABILITY TESTING (HIGHLY TRICKY. Per-core CO on my 5950X. Would like to tweak it per core and needs your help / guidance. /r/AMD is community run and This per-core MHz limit could also influence the CPPC preferred cores, so Windows schedules threads on the truly best cores instead of whatever they picked at the factory. kuvi ayi mrebo rof jgstnny kntsls cugni mkgbkx vejpl nuwstdq
