Curve optimizer not working. OCCT using Small Data Set, SSE instructions, 1T.

Curve optimizer not working. All of the things we're discussing fall under PBO and PBO2.

• Curve optimizer not working When optimizing ALL cores, the computer turns off and on instead of rebooting. 0 w/ Curve Optimizer: Undervolting is a way of overclocking CPUs and GPUs that have an internal table that maps voltage to operating frequency. I know not many are running VMs, but i would be curious what anyone else is getting in a VM. However, even that might not be true on a single sample and so copying someone else's recommended settings is probably not going to work well. OCCT using Small Data Set, SSE instructions, 1T. Auto curve optimizer is not reliable. Is it applying a static offset to the voltage delivered to the CPU or is applied to the final voltage delivered to the CCXs/CCDs/individual cores? I'm not trying to be an ass, I haven't had an opportunity to play with this feature yet. 15ghZ but that didn't work so I tried going back to 5. The Ryzen Curve Optimizer enables individualized voltage-frequency tuning. Positive offset would let the CPU use more voltage to achieve higher clock speeds if they weren't possible with a lower voltage (theoretically, and only if the thermal and power headroom allows it), and negative offset will result in the CPU asking for less voltage overall, which will lower temperatures and can result in your Curve Optimizer will tweak the voltage/frequency curve so that the processor can run at a higher frequency at the same voltage. Further reducing the Curve Optimizer to -35 did not result in additional frequency, however it did reduce the voltage by 7 mV. Is PBO2 + curve optimizer available feature in A520? ~~~~~ Edit: (Solved) After receiving my parts, here is my findings, You can turn on PBO and set power limits, PBO scalar and curve optimizer on a520 boards, specifically Gigabyte A520i AC. Reply reply If I understand correctly, Start Optimizing is intended to automatically try and find the best offset to use, and Validate Offset is to test the current offset. zerijelly Well-known member. im on -30 on all cores working without any issues It's easier to first find a stable all core curve optimizer and then go from there, i started from -10 all core. I only have a Validate Offset option. Load 7 more related questions I just noticed that the auto curve optimizer completion time is affected by the 'stress time' value in the settings page. Here you can change many things, but i only change the CO Values to -20, which gave me additional 100-200 mhz under high cpu load. Max boost clock override (AutoOC) +200 MHz I have a Dark Rock 4 cooling my CPU along with good case airflow and this works great for me. If it is caused by iCue, contact Corsiar and create service ticket for iCue This is why you see recommendations like set your best cores to X and all others to Y. FIRST LIEUTENANT. Vcore offset moves the entire curve up / down. 8E-13, the First image is stock and second is with my +200MHz curve optimizer undervolt and with the same stock limits. It applyes, bot nothing changes, even on -50mV. Example: Browse If i select auto for curve optimizer , it keeps working. @Wickedtt mentioned here that Curve Optimizer first appeared with AGESA 1. 0. Note - Ryzen Master was running in the background for We're testing on a Ryzen 7 5800X purchased at retail with an ASUS TUF Gaming X570 Plus Wi-Fi, 32 GB of Corsair DDR4-3600 CL16 memory, and a GeForce RTX 3070 Founder's Edition. Amd The following guide should work for the following CPUs: Ryzen 9 5950x; Ryzen 9 5900x; Ryzen 7 5800x; Ryzen 5 5600x; The following should similarly work for Ryzen 3000 series, but you will not have access to the Curve Optimizer. Warzone no whea errors or crashes. Joined Oct 6, 2022 Messages 962 (1. My 5600x only runs at 4450 when fully loaded with a CPU burner, system is tune the AVFS curve of the entire CPU or specific cores of the CPU such that the tuning overrides the fixed curves that they are fused with, resulting in an increased CPU performance. Curve optimizer . As a good precaution i would suggest running the full 6m per core test at least few iterations to make sure everything is actually long term stable so you wont crash later mid The curve optimizer its like I said, its not a statement from my end. OP Joined 12 Jul 2007 Posts ive been running -30 curve optimizer since the day i bought it (last 2 weeks ago) been playing warzone, left the pc on for 2 days because i was downloading games (on a 10mbs internet, its free intertnet in my apartment) seems to be stable, i never had a blue screen or random restart. weeks I've been working with the Curve Optimizer for Ryzen processors a bit more, but I hadn't found a good way to test the settings for stability. Reactions: Roland Of Gilead and kurdtnz. 2 SciPy Curve_fit() doesn't fit curve. The 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. during normal work, etc = during short bursts (with not enough cooling headroom). The function (curie_func in the code below) should work and I have tested plotting it with realistic values as initial parameters (p0) to demonstrate it fitting well. This is my first AMD and most I read a lot about undervolting with ryzen master and Curve Optimizer, but it seems its completely not working on my system, to put it simply, it sets the values that I set as maximum, if I set the maximum offset to 30 it gives -30 to all cores, if I set it to 33 it gives -33, and interestingly it sets the first core either to -50 or -255. All of the things we're discussing fall under PBO and PBO2. Adjusting all cores does work and have a measurable effect but now i wanna go deeper in the topic and set up a "per core" setting. Welcome to the Ender 3 community, a specialized subreddit for all users of the Ender 3 3D printer. Difference is small but it is there Hey all! I previously posted about my recently built machine being unable to sleep properly on Linux due to issues with EXPO, I’ve disabled it and it appears to work properly. Or Curve Optimizer lets you tune the VF-curve per core or all cores in BIOS Of course it should be updated in the next couple days with other goodies from AMD,but as of now for stability it works awesome and you get great single core/multi performance. optimize) assume that parameters are continuous variables, not discrete. I then ran Try a setting of -15 all core and test for stability, -30 allcore is fine for some cpu's but it can freeze the system when it's idle. 1% can be ignored as it's too short benchmark to get enough frames to have accurate data Hello! I'm having trouble Curve Optimizer feature in Ryzen Master. CineBench single threaded almost always Also i was interested in the eco-mode to switch to when i'm doing light work. MSI Afterburner fan curve not working Build Help Background: I'm running a Rog Strix RTX 3080 OC, undervolted. Tested Curve optimizer at -10, -15, -20, -25. 8E-13, and is instead giving me n = 2. 1. Reply reply the 5000 series boost algorithms favour lower temps, so lower temp can equal higher boost freq, at the very least higher sustained boost. curve_fit Failing to Fit Function. 0 scipy. But i never used the ryzen master app except to check on temperatures and frequency . because power is not the limiting factor in your gaming clock speeds. After it finished AMD ZEN 3 PBO & CURVE OPTIMIZER OVERCLOCKING GUIDE. For brief background tasks or destiny the working thread is something like 20%-50% so that eff clock can't be a measure of clocking stretching. Join us in celebrating and promoting tech, knowledge, and the best gaming, study, and work Hello, I have an x670e-F with a 7700x, running on the latest public UEFI (2007 right now). This went all great when I tried to generate a curve with the curve_fit example but not when I use my own data. . So I tested my previously determined CO values and Ryzen Master Auto Curve Optimizer settings are very optimistic and way over shoots what is actually stable. -5 all core otherwise I’ll get lockups in idle situations yet at load it works perfect. If you leave it at "OFF" and perform optimization it just returns settings to defaults, No Optimization. I know that it works for others, but certainly not for everyone. Going to -30 was mildly unstable. I had reduce my curve optimizer negative offset from 28 to 26 after two system crashes confirmed that my 5900X was not stable at low load levels. If you were to cool the CPU with chilled water (-5C or so), you would probably see lower temperatures from tweaking curve optimizer. I am currently running a Legion 7 Gen 6 I have a 7600x. michty_me. Processor: AMD Ryzen 7 5800X3D It's not included in some motherboards but I bet it's due to justing manufacturers being lazy. The fitting procedure will try to take small steps (typically around machine precision) in the parameters to get a numerical derivative of the residual with respect to the variables (the Jacobian). It's a bad comparison if you're talking about 2600 or 3700X though. Not sure if that's good for a virtual machine or not. I experienced a similar thing when I switched from 5600x to 5800x (not 3d one). Only B650 motherboards I experienced the same thing, the app wasting hours and giving an all core -30 result, which is completely unstable when set from the BIOS. Therefore, while fitting exponential functions with exponents depending on time stamps, the best is to adjust the time exponent by excluding the time of the first data point, changing it from:. Joined Nov 14, 2020 All brands/500 series (not sure about 400) motherboards should have Curve Optimizer I think since AMD added it with the latest AGESA. Benchmark was doing 15 laps around my raft. Maybe yes, but maybe with lower ppt ( so you force all cores in lower freq and voltage). -Cleared CMOS. How can i switch ryzen master to english on german windows 11 ? I use default values -30 to create the curve and no crash reboot during curve optimaze h I recently had to soften my CO curves a little bit after configuring CoreCycler to work with 720k-720k block size. Any help is much apprecaciated. optimize import curve_fit If you really want to get out everything, curve optimizer is weeks or even months of work for +/- 100-200 mhz. At this point the CPU is very close to the thermal limit as it reaches close to 100°C scipy's curve_fit (and all other optimization routines in scipy. Upvote 0 Downvote. 3. Since then I’ve run into some odd behavior on my installed system which I won’t go into specifics, I tried looking into them but couldn’t find anything of use, until I started suspecting hardware Some motherboard don't have Curve Optimizer or PBO control for 5800X3D since OCing the 5800X3D wasn't officially supported when it released. I had check all of it, any options, no way to undervolt my R7735HS. 12 and I = 2. "Curve Optimizer" settings are actually stable. You have to determine what works for your processor. This curve optimizer is awesome. Home. I go to Advanced —> AMD overclocking—-> accept ——Percision Boost Overdrive—-> advanced. Set my curve optimizer to -18 -18 -18 -20 -25 -25 +200 on +MHz Get around 11900-12000 on r23 at 77 degrees No errors or random restarts. Than you must lower the PPT TDC EDC as much as you can without loosing performance while lowering the temps. #=====# The goal of this community is to provide a wide variety of That's not exactly what curve optimizer does. Don't enable vcore dynamic offset while using curve optimizer and disable the boost and scalar completely. After reviewing some co boosting data at low and high frequency, I saw that the low freq undervolt was more significant (vs stock) than the Hello friends Faced such a problem. Though I noticed my fan curve on MSI Afterburner is not working at all: https Ryzen Master Curve Optimizer, how to know it's really applied? self. scipy. Curve optimiser gives better Turbo boost multipliers at multicore tasks by downvolting CPU curve, afaik. B620s can only use XMP/EXPO and does not have access to other OC settings. But I would play with Curve optimizer, its not really an overclock, It just changes where to apply more voltage at a It seems like it only fits the first parameter. And then drop PPT to 180W. DANGER! Finally I set the curve optimizer to -10 all core, and behold, I get around 620 SC annd 8700 MC. The 5600x in my new A520 board goes to 4. 1% lows. But to say it's useless, or more specifically, "hype", is not true. The previous BIOS version comes with AGESA 1. Open it, navigate to Clock Control. It shifts the actual voltage and temperature curve of the CPU/core down. AATU (or Similar with curve optimizer. 2. Ryzen really has come a long way. My CPU's best cores are Core 0 and 1 in CCD 0, Core 6 and 8 in CCD 1. HOW? ---- Double click the "Run CoreCycler. I’ve also tried 105 watt eco mode with 33000in multi core without curve optimizer and 35000 with curve optimizer. I suspect this is due to the data set values being very small numbers, messing with the optimization, but even when i set the initial guess to be n = 1. 15 and Io = 1. Setting max boost override to +200 MHz (which gets others up to 5 GHz I have tried using the curve_fit function from the scipy. 8ghz ST and 4. I just want my rig to run cooler. Try to identify the best cores with Ryzen Master and start pushing the good cores up. Reply reply Wint3rmu7e With 8 cores its much easier to do a per core curve optimizer. Z. Mine seems to be pretty strong and my weakest core was still able to go negative 18. 11E-11. Skill Flare X5 6000CL36 64GB (4x16GB) / Samsung 980 1TB x3 / Super Flower Leadex V Platinum Pro 850 / EK-AIO 360 Basic / Fractal Design North XL (black mesh) / AOC AGON 35" Scipy optimization curve fit not working properly. I have two of my cores boosting to 4820mhz constantly for long durations on my 5600x (previously maxed out at 4640 mhz boost). I'm trying to optimize my Ryzen 9 5900X CPU cores with AMD Ryzen Master Curve Optimezer but it doesn't work. It's legit. I'm working on memory OC now that I've rid myself of the majority of cache throttling through better optimizing the CO curve Once that's "complete" I'll likely move on to using Hydra Pro to further refine the curve from within the Follow up: I decided to lower the values in Curve Optimizer. Hello I have a 5600x with pbo and auto oc (+200) active. Hi there guys, just an small post to gather some curve optimizer negative offsets on your AMD Ryzen 5000 series. It works. curve_fit doesn't fit. Reactions: 3x0. optimize package to fit a set of simulated data to find the curie temperature of CoFeB. I'm currently working on optimising my Curve and stability testing using Corecycler (it's awesome and the only script/application that's managed to find unstable results - P95 after 12 hours reported no errors. If even a single core doesnt like -30 it will crash, either do a lower all core or tweak per core. com)) and was very confident that I had learned about the somewhat unusual test of forcing "Windows 10 Automatic Repair and Diagnosis" for ten times. I lost 10c not only in all core cinebench but also in cyberpunk and new world. LtMatt. Now CO is stable again at -23 across all cores in my On a new PC build and fresh installation of Windows 11, with all BIOS settings at default except for the RAM profile set to EXPO, my system was running normally. I wasn't sure Curve optimiser defines the shape of the voltage curve. Curve Optimiser shifts the voltage/frequency curve, setting a negative offset shifts the VF curve so that the core will boost higher at the same voltage. Also the curve optimizer has way more effect on temps I am trying to fit and subtract a curve to this dataset to remove long term variations, like this: where the blue curve is the original (offset added to see the difference), then the orange is the result of fitting then subtracting. Aug 8, 2008 11,559 2,775 80,240. Thanks! 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, and performance, at some arbitrary curve optimizer offset steps. If you have one of these boards, it doesn't surprise me at all that curve optimizer and/or PBO would "work" in the BIOS but would still not be available via AMD's official Ryzen The best rated cores will often times do most of the highest frequency work and as the overall workload increases and the overall clocks come down the worse cores will get loaded on to. 0, using curve optimizer does not seem to be changing my power draw at all. It should even work on int data. Yes, PBO is considered overclocking. With this script you can test the stability for each core, which helps you to validate if your Ryzen "PBO" resp. Caporegime. Will Have to do that test again. There is no Curve optimizer option listed. I set it manually to different negative values and I don't see any difference. If it even crashes once it’s still not good, warzone or Cold War is utter shit coded since everything else works. Take a step back and first understand which are the relevant bios settings. 1 auto curve optimizer feature takes a lot of the work out of Thanks to this video:Disable c-states for better curve optimizer settings on Ryzen 5000 zen 3 PBO - YouTube You need to disable "Global C-States" and "DF C-States" in the BIOS. I hope you Large negative exponents make the exponential function close to zero, thus making the least squares algorithm insensitive to your fitting parameters. How can i switch ryzen master to english on german windows 11 ? I use default values -30 to create the curve and no crash reboot during curve optimaze h Curve Optimizer not working at all on B550i Pro Ax? Hey, I'm on F13 BIOS on my B550i Pro Ax and trying to use Curve Optimizer but I see absolutely no difference between it being on and off. What I've found is that curve optimiser was stable under very high load tests, but games that only used a few threads would crash. Roland Of Gilead Titan. You can see obvious improvement. Skill Flare X5 Series 32GB DDR5-6000 Also few tweaks to make this faster. -Flashed bios BACK to known good version 3401. My setup: Ryzen 7 7800X3D AsRock B650M Pro RS 2x24GB G. At idle or moderate load the voltage is lower - sometimes too low with aggressive curve optimizer negative offsets. I only really touched the Curve Optimizer section. How to access Curve Optimizer feature in Ryzen Master? A dedicated profile is provided for this feature named as "Curve Optimizer"€ Is it supported on all AMD CPUs? Hello guys I tried using the curve optimizer now the first time I got it to work all cores 5. So, instead of getting a list of specific tunable V/F points, we get five regions and three temperatures: Ive run both the curve optimizer on Ryzen Master and the optimizer on the HYDRA software and they both set all my cores to a -30 offset, how reliable is this? Ive not had any issues gaming, running benchmarks etc. Curve Hey, I just wanted to share a quick overview over the results I got, with like no effort at all. However, decreasing the curve optimizer to -30 decreases the max single core to 5600Hz and max full multi core to 5400Hz. I had to use -20 all core in curve optimizer to be able to boot. To put it succinctly: Curve Optimizer overclocks your CPU. Seems like my AsRock board lets me go well past -30 on the curve optimizer. Results From Curve_Fit Are Off. bat" file. Over the last couple of days resp. And if it turns off and on for the first time, then when you reboot, the op Curve Optimization is very easy - the testing being automated - and poses no danger whatsoever to one’s hardware; the worst you can expect is a Windows bluescreen, and that is no more deleterious than stalling a car. Fingers crossed the CTR 2. I tested offsets manually starting at All Core at -30 and ran Cinebench to validate. this has something to do with 0 and 1 being preferred cores so they tend to boost higher already in lightly threaded work loads. 3, no matter if I put the negative offset -Reverted all bios settings back to standard/auto and did not mess with PBO/Curve Optimizer-Purchased new AIO Your system is working as it should be with perfect low temperatures. Reply reply The on 1. 1ghZ and -30 on curve optimizer. But at that point you Right, exactly. Curve Optimizer values for the best cores are -12 and the rest are at -20. Forums. The setting were: -15 to -24 co X10 scalar +75mhz 150/95/148 power limits I started researching curve optimizer threads again. Reply reply lexsanders • Idk why you would say that, it's not correct. Incorrect adjustments can lead to system instability. This is apparently a common instability condition for Ryzen when undervolting, but it's also hard to test, because the only way to test it is to leave the computer on for several days and see if it After I had been working with the Curve Optimizer for some time. Setting a positive 200 to PBO max boost clock increase and a -27 to the curve optimizer, I was able to increase the max single core clock speed to 5850Hz and the max multi core full load clock speed to 5500Hz. For everyone messing around with PBO2 Curve Optimiser to undervolt & OC their CPU's, here is a stability test I have found useful. Curve optimizer works exactly the same way on X3D and non-X3D. CPU is so strong even with 5200 RAM (also with 4800 MHz) it runs very efficient and powerful Here’s my strategy to making Curve Optimizer somewhat useful: Manage to get it to complete (the hard part) Take down the optimizer values on my phone or a notepad Anything with an offset over 10, reduce the offset by 33%. However, curve_fit only worked successfully for the first 49 iterations, and after that curve_fit stopped working--to be more specific, the curve_fit function did not return anything, and Attention! By: u/DragonMaster9595 - the curve optimizer settings can only be used by renior apus, and ryzen 9 hs or hx czn and rmb apus. I’ve started at offset of 30, but it crashed while logging to Windows. It also works to test Intel's "Active-Core" Turbo-Boost settings. Single core stayed the same though out stock, 105 and 125 watt eco mode. You can try with PBO2 Tuner from PJVol over at overclock . PBO2Tuner works exactly same as BIOS curve optimizer. It first found core 2 giving errors, but it was working, decreasing the magnitude 1 by 1, I found that at -15 its actually resterting my system when Ive had a working and stable co set up on my 5800x for quite some time. I tried to put one core at +0 and all other cores at -30 in order to see a And I tested what the person did on the video and it's impressive how the temps lowers very significantly while keeping the cores working as normally would, so at least under some kind of load the system seemed stable at -30 on all cores in curve optimizer, didn't got to test on idle yet so as you guys said that might be the trick to test, also Started to play around with PBO. Default is 30s. GN is not infallible. From Zen1 (Ryzen 2000 series) to Zen3+ (Ryzen 6000 series), please join us in discussing the future of mobile computing. Works in laptops, monoblocks and desktops. Temps are 95 stock 70c 125watt eco mode and 60c for 105 watt eco mode. I never used either of those options, and I've seen others report they don't work correctly anyway. Cinebench r23 multicore: Stock = 15333 88c, -10 = 15640 88c, -15 = 15444 90c, -20 = 15803 83c, -25 = 16028 83c -20 seems to being doing great so far. Basically, a 50mV undervolt tells a CPU that instead of operating at, say, 2GHz at 1V, operate at 2GHz at 0. The higher frequency is directly a result of a lower voltage (heat). i'm trying to do undervolting 5800x3d with pbo2 but it's not working at all i tried from -5 to -50 but nothing idle is 43 under load is 90 cb r23 i did Menu. B550 phantom itx - curve optimizer per core option not showing cores This is because curve optimizer is applying a static offset to the final voltage the cpu runs on. From what I can browse, overclockers forum, redit, and all that. Curve_fit not giving parameters to fit data correctly. Then i enter valeus above in curve optimizer and i had a boot loop (automatic repair). EXCEPTION OF CHECKING THE MACHINE. At the time I was just using curve optimizer and a gpu uv, however I improved my setup with the following settings; custom per core curve optimizer through ryzenadj (median about -20), sppt to 110w, in umaf bios no cppc preferred cores, scalar to x1 and custom dram timings at 3600 c20. When a core is under load, it gives it extra voltage. CO is better than PBO at getting higher clock speeds in gaming. So you ideally need a curve that works in multi and single load scenarios. When I resetted cmos 8 core curve optimizer came. Joined 19 Apr 2012 Posts 5,313. I've been trying to fit a function to some data for a while using scipy. So you won't see your voltage change, and Ryzen master won't show curve optimizer. But there is also a Curve Optimizer in Precision Boost overdrive under the advanced/amd settings How do I know it's working, what should I But if it works better or not depends on many factors: ram density, MB, bios, agesa version, luck, ecc Sometimes works best with the automatic all equal, sometimes it's best with little gaps, and some other times you can also use very large gaps like I Can’t help with the CPU, maybe Universal X86 Tuning Utility could work on the FW16? 1 Like. Really glad people are working on core curve optimizers. Benchmark numbers are in order: average fps, 1% lows, 0. Discussion Hello everyone before i mess with the settings i read and try to understand how everything works. 0 Python scipy. AutoOC is the same as Boost Override and it was in the original PBO, now in PBO2. I have been looking at the app (at work at the moment) so will have a try with that tonight. The same curve optimizer settings wont work for everyone, especially if you do all core. -Reinstalled Your Ryzen Master Advanced View Curve Optimizer screen indicates it is set to "Auto Offset" Some motherboard don't have Curve Optimizer or PBO control for 5800X3D since OCing the 5800X3D wasn't officially supported when it released. Works for intel 4 series and up and amd zen series and up. In particular, there's no good reason for curve_fit to fail on float32 but succeed on float64 data. Edit: Real world example. optimize_curvefit gives bad results. It just doesnt affect scores further. But 7th and 8th cores were zero. especially with Zen 3 chips and B2 stepping. And I ended up lowering the negative offsets from what RM set, while testing each core, trying to find the best results. 26-26-26-24-26-26. The 5800X3D doesn't officially support PBO or curve optimizer. Elmor also mentioned a little about Every real work cycle increases the performance counter & wait cycle / not working cycle decrease the performance counter. It's not about the hardware in your rig, but the software in your heart! Join us in celebrating and promoting tech, knowledge, and the best gaming, study, and work platform there exists. Steps I have done to remedy this: -Removed riser cable and reinstalled GPU normally. Through manual overclocking the limit was found to be around 4650 MHz with 1. Set Curve Optimizer to -25 on all cores - how stable this will be is entirely dependent on silicon lottery, but -25 on all cores is 100% stable for me. 8. curve_fit to fit the data, and I have more than 10000 data sets to fit, so I used a for loop to run curve_fit for 10000 times. 1 and 5. Uninstall Ryzen master and made a clear cmos. 30 works as it was a bust in a 5800X3D. my guess is due to small amounts of 7950x3d being sold these You don't necessarily need a PC to be a member of the PCMR. It does not feel good though Id much rather be able to adjust in bios, I'm one of those weirdos that wont even install a game if it uses a different launcher than steam :) I didnt know about the CPPC so ill make sure to check that also How to overclock using Ryzen Master and the new Windows feature - Curve Optimizer. AMD Ryzen 7 5700x3D Curve Optimizer or UndervoltingReducing Core Voltage reduces (Vcor) power consumption and CPU temperature. very impressive, just wish it would persist after reboot because I'm gonna forget. It actually finished Cinebench R20 with 25 offset, but would crash instantly in Doom Eternal. The IO die is much more stable now and the AGESA's are optimized and refined. 0 Patch B or C). 15 and Io = ~1. Open the Core Cycler config at change the run time to 2m at first and do the changes to curve optimizer values after first iteration. Skill RipJaws S5 DDR5-6400 @ DDR5-6000 / 1,3V Thermalright Phantom Spirit SE 120 Results I've been toying with my new 5900x chip, and have been reading up on the new PBO2 and curve optimizer tool. 13 Mar 2021 at 20:57 #10 michty_me. However, what I have tried is not fitting the data. 3x0. I read we need to test how the CPU works at low/light loads and idle as well. However, for some reason my fit is not working and the output has been looking like this: Wasn’t aware that there was an auto curve optimizer until now. if you are prepared to leave it running overnight and/or while at work, though, this is not a problem – and it can take a When I look online, guys advertise a curve optimizer at -30 (or more) without flinching and without doing anything special. I've lost about 1200 points in CinebenchR23, it used The rig runs hot as hell, even with the noctua heat sink + intake fan I added so I tried to undervolt it in the BIOS but there’s no curve optimizer prompt. Ryzen 7 7800X3D B650 GAMING X AX V2 G. As for temps, you need to set lower power limits in addition to setting curve optimizer, to get the biggest temp reduction. 29 V actual voltage during load. CJ_Elevated February 29, 2024, 1:06am 3. Key Takeaways. UXTU Curve Optimizer didn't work. Chaotic_Sandwich: Is there a hidden BIOS menu for overclocking Just got my FW16 DIY with a 7940HS but cant find any way to access the curve optimizer or change ram speeds (currently ram is stuck at 4800) Is Curve Optimizer - per core, -25,-25,-25,-20,-15-15 Max Boost Clock Override - 200 MHz Thermal Throttle Limit - Auto Mine is not great either. I could go more negative on my stronger cores but it didn't make much of a difference in my testing so I didn't spend the time to find the exact limit for individual offset.
