Ryzen 7900x curve optimizer reddit
Ryzen 7900x curve optimizer reddit. Each core has multiple V/F curves that vary depending on load on the CPU. Also spikes in temps are normal. I’ve gotten these numbers using Cinebench r24 and observing with hwinfo64. i really wish i could get your hashrate but unfortunately my motherboard and ram are different and im just getting 16. Considering CPU temparature and Cinebench R23 performance, it looks 105W/125W Config TDP is good for my system. Apparently the Ryzen 9 7900x has this big issue of CCD processing. My 7800x3D was idling around 55c and now idles around 45c. It sets too high values and sort of guesstimates like Hydra tool. The one in optimum tech seems to have used curve optimizer and something else. Both the 7900x and 7950x are happy with any proper large tower cooler or good aio. 0) : Amd (reddit. (Ryzen 7900X + Noctua NHD15-S black) and got idle temps of 60 to 65 degrees celsius and it jumps to 90 degrees when the Windows Defender is doing a quick search in the background (and the CPU only goes up to 20 or 30% usage during this). I appreciate any advice you could give, thanks! Jan 30, 2021 · 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. With Curve Optimizer -30, it's about 7% higher than stock 65W PBO settings. I use another tweaking utility called Hydra and it did a great power play table mod to my 6900XT, but it's PBO and curve optimizing tool isn't as good as Ryzen Master's auto curve optimizing tool. Current Setting: I am currently running my Ryzen 7950X on 105w eco mode on Bios with -20 on All Core with curve optimizer. Have a quick google about Curve Optimizer first and then go and have a bit of a play with it. You're better off doing curve optimizer the old fashion way. Auto curve optimizer is not reliable. It needs to be made less aggressive, but judging from the lack of interface updates, AMD isn’t sinking as much time into development of Ryzen Master. The processor is running at 5. I also believe it's disabled for x3d CPU's. When I am looking at the frequencies, they are up to 5300MhZ for CCD1, and 5150 for CCD2. I already used curve optimizer in BIOS (I set mine to 15) but, it barely help. Enable Precision Boost Overdrive and then enable Curve Optimizer. With the advanced boost curves these CPU's have, manual voltage adjustments are only really useful for static manual clocks. Curve Optimizer can be found in “OC\Advanced CPU Configuration\AMD Overclocking\Precision Boost Overdrive”. Wow, just adjusted my 7900x system and the high temps/fan noise are gone! Set eco mode to 105W, curve optimizer to -25 (had been stepping it down slowly to see how far I could push it, was at -20) and turned expo on, that's about it. im trying to run the optimizer for my ryzen 7 5800x. 4! The boost also went up from 5. And I ended up lowering the negative offsets from what RM set, while testing each core, trying to find the best results. We extended the Curve Optimizer range with the release of the 7000x3d CPUs. My workloads typically run lots of VMs which are relatively busy and would prefer to keep noise to a minimum. I think I am out of options. More performance, less power usage, and lower temperatures! I’ve also tried 105 watt eco mode with 33000in multi core without curve optimizer and 35000 with curve optimizer. i also have zero knowledge/experience of tweaking ram/cpu in bios or even in ryzen master. May 19, 2023 · Try first a -5 then -10 and lastly a -15 on all core and see how it goes, keep an eye on temps and vCore. I’ve looked at some similar posts, and while they are also running higher temps than usual, they don’t seem to be going over 50 degrees at idle. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. Also, it’s normal to have one CCD slower than the other. TLDR: My 7900x is stable (at least from 24 hours of torture testing and ovber 48 hours of normal usage) with a -30 Offset per Core. This potent system I use another tweaking utility called Hydra and it did a great power play table mod to my 6900XT, but it's PBO and curve optimizing tool isn't as good as Ryzen Master's auto curve optimizing tool. CPU Cooler Artic Freeze II 240mm AIO. I tried it, just to get a rough idea of what negative offset values to aim for. Undervolting means you will have instabilities at low clocks not at high clocks. Lately I've been toying up with PBO2 with my 5600X. I want to ask about this Ryzen tool that is supposed to automatically curve optimize. my bios doesnt have "high bandwidth support" option (although i think expo profiles automatically increase Core Optimizer is very heavy-handed with the curve offsets, so it’s definitely not unheard of. This increases performance and reduces power usage - it is basically an efficiency setting. to check of instability. With ECLK, we still build on the factory-fused VFT curve but adjust the frequency by adjusting the reference clock. but before this, i ran -30 all core. Would like to tweak it per core and needs your help / guidance. 97v, its an asus tuf b650m-e and klevv cras v rgb 6000 cl30. Hi, I am fairly new to overclocking. So you ideally need a curve that works in multi and single load scenarios. I have also Jul 26, 2024 · As shown in OC Strategy #3, Ryzen overclocking is typically done with a negative curve optimizer. 7900X + Gigabyte B650M + 32gb G. Ran both per core and all core curve optimizer in Ryzen Master and both came back -30 for all and per core. The PPT/TDC/EDC settings of the PBO Enhanced Mode can be seen via Ryzen Master. Maybe a better cooling solution could eek out a bit more performance, maybe. It's tedious and long but it's the only way to guarantee stability. Each step is around 3-5mV. The only setting I've really done is enable AMD Expo, and adjusting the fan curves to how I like. Specs: Windows 11 PRO | RTX 4090 (80% Power Limit) | DDR5 GSKiLL 64GB (32x2) 6400mhz CL32 (Underclocked to 6000mhz CL32 - Tried most things but anything above Ryzen 9 7900x EXPO II enabled, Memory context enabled, PBO Curve optimizer set to -20. AFAIK, ryzen 7000 series are made to work at 95 Celsius. After I had been working with the Curve Optimizer for some time. PBO with curve optimizer (manually tested over months) gets me to like 4,5-4,6 ish. :-) take care! I don't think tuning curve optimizer on a single core basis is a great method for finding a stable curve. The whole point of negative PBO is to "make room" (in voltage) for more and longer-sustained overclocking, including via built-in mechanisms like Core Performance Boost (CPB). I tried with ‘per core boost boost clock limit’ option, by limiting these cores to ~5. RTX 4090, Ryzen 9 7900x, 2x32GB DDR5 6000Mhz, 1200W Corsair Platinum, Gigabyte B560M Aorus Elite AX, 4TB Kingston M2 SSD Some people on some other forums told me it's the Ryzen. It's Ryzen 9 7900X. Increasing negative value for cores 3&10 with Curve Optimizer doesn’t get any temperature reduction. So be sure to set aside some time, but it'll be worth it. 29v to 1. I read the guide from katalysis (Guide: Zen 3 Overclocking using Curve Optimizer (PBO 2. 3 - 4,4 Ghz (Blender) without even touching any EFI setting except XMP. When using Curve Optimizer I noticed that average vCore drops but maximum vCore goes up, because it will boost higher. 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 and use Ryzen Master and its auto curve optimizer. ) PBO PPT/TDC/EDC: 95W/85A/120A A comment on a small part of this. Single core stayed the same though out stock, 105 and 125 watt eco mode. SOC voltage is the voltage to the integrated Memory Controller. The scores in Cinebench R23 are +- 28. . Now I am very confused because some YT videos and folks on Reddit tell me it's normal and that's what the CPU was designed to do, some people and YT videos report they never get over 80-85C even under 100% load. 7ghz, 1-0. Temps are 95 stock 70c 125watt eco mode and 60c for 105 watt eco mode. As the table shows, with 95W Config TDP, Ryzen 7700 is 3% faster. You can however play with Curve Optimizer (CO), and set a negative offset for the cores. Get the Reddit app Scan this QR code to download the app now 7900x, -30 all cores in curve optimizer OC Report - CPU come talk about Ryzen, Radeon, Zen4 Then download Ryzen Master, go in advanced mode, curve optimizer, select "per core" in the middle and then "start optimizer" (or something like that). I followed just the curve optimizer guide on my R5 7600x and my Cinebench score went up by almost 1k while the max temp dropped from 92 degrees C to 78. Hey, i just got a quick question. A good cooler makes a HUGE difference. My System: CPU Ryzen 9 7900x. It’s faster than stock Ryzen 7700X too. However, Cinebench works I just finish building a PC using a new Ryzen 7900x CPU. Parts Ryzen 9 7900x Lurker AIO v360 Lian li 011 dynamic evo All fans are uni fan al120 This reddit comment is a good way to tune curve optimizer: https://www I’m considering using the curve optimizer, but before I do that I want to see if there is anything I can do. In games, 4K max settings, my 7900x keeps staying around 90-95C. I have a Corsair H150 AIO and I adjusted the fans so that they have a flat curve until it hit 65C. On Ryzen 3000, there's also CLDO_VDDG (commonly abbreviated to VDDG, not to be confused with CLDO_VDDP), which is the voltage to the Infinity Fabric. the 5000 series boost algorithms favour lower temps, so lower temp can equal higher boost freq, at the very least higher sustained boost. Undervolting/curve optimizer essentially overclocks your speed at the same wattage, so NO you won't get better temps unless the CPU wasn't being loaded 100%. This is kind of expected, just be aware. same thing that happened to me, i got a 7900x for 390 at micro center, while 7700x was 350, the 7900x i tested was a golden egg, tested 2% over average 100% 7900x i run it at default and never get past 70, usually sits 45-60C running obs and multiple apps in the background. As 125W + Curve Optimzer -30 applied, the Cinebench nT performance is close to stock Ryzen 7900X. It's a lot of trial and error but you may be able to work a bit more around the edges. Until now I’ve done the following: Adjusted the curve optimizer magnitude to -15. 1Ghz on the first 6 cores and 4. I got Ryzen 5 7600 and i went to Ryzen Master, Curve Optimizer, Control Mode Default, i went to Cruve Optimizer Control and click Optimize All Cores and my system tests all Cores for 40 minutes and determine lowest Vaue of -60 OC so i save apply it my PC restart but in home screen it shows that my CO value is -50 even its set to -60 in Optimizer. Tried with Curve Optimizer (negative 30) to see the performance change. Even with the curve optimizier in the DUO 16 we aren't hitting max possible performance in the 7945HX. A quick Do the curve optimizer, it will lower temps. Oct 6, 2022 · MyKillK combined a general core voltage offset with Ryzen Master's Curve Optimizer function to end up with a -50mV overall undervolt and then individual offsets for each core ranging from -30 Mar 15, 2023 · I have also tried the traditional method of using the curve optimiser with PPT 180000 and negative -20 / all the way down to -1 but still get instability and BSOD on each value. I am currently running an ESXi server on 5950x (with 128GB ram) and I am wondering if it is worth upgrading to 7950x. And I'm still trying to work on that. i'd personally recommend a good air cooler for 7600x, 240 aio or double tower cooler for a 7700x, 360 for 7900x and 420 aio for the 7950x. 0 GHz, but as soon as I launch an all core test, cores 3 & 10 stucks at 4. It is set to the reducesd 120W TDP settings (so max 162W) of the X3Ds and to counter the curve-optimizer is set to -20 so CPU stays <90°C with air and no relevant noise. Ryzen Master per-core curve optimizer recommended -30 for all cores. On 8 cores it take about 1 hours so it may be longer on your system but in the end, it will give you value for each core for curve optimizer. 4 to 5. Just scored 29000 (exactly 😁)This is an air-cooled (be-quiet Dark Rock Pro 4) 7900X on a MSI MPG X670E board. I too came from Intel to amd and was shocked to see the idle temps like this but yes it is normal I guess. There are certain low profile air coolers that can perform: one of them being the Thermalright AXP120x67 -- however people have had mixed reports between running their 7900X on eco-mode or just undervolting. Setting curve optimizer to -35 decreases the max single core to 5400Hz and max full multi core to 5250Hz. More performance, less power usage, and lower temperatures! As far as I am aware hardly anyone has getting more than -30 on all cores mostly the prefer cores. But without a vcore offset and with the max pbo curve offset of -30 (x 3v for a max load offset of -90mv), the lowest vcore at PBO max boost is still 1. Multi about the same after lowering the curve optimizer but single threaded performance went up. but it shows me it takes 11 hours and 30 min to complete. Did a quick test on Ryzen 7900 with different PBO settings and Curve Optimizer and see how the performance scales and CPU temperature. 7 GHz. SKILL Trident Z5 6000 + Arctic Liquid Freezer II 360 BIOS: Hard to compare BIOS settings, but I tried similar changes -- Curve Optimizer Negative 30; Thermal Throttle Limit 85°C --- ultimately decided to return to defaults with PBO on auto and let it be. It appears that it's not enough. On cinebench, my CPU is up to 90 degrees, so, normally it should have some room to go up to 95, which is not the case. Started at -10 and increased by 5 after each test. 500 points. Skill FlareX 32gb DDR5 Gigabyte 6750xt OC Gaming Superflower Leadex SE 1000w WD SN850X 1 TB My general usage is gaming, music recording, some video editing, but nothing too CPU intensive. For example: On my Ryzen 5900X I get a All core 4. Reduced vcore offset accordingly. The AI optimizer recommended an all core -42 for me which I thought was insane. Chose to test per-core and after a hour of testing it came back with a -30 on all six cores. Currently running (5600x) Auto OC + Curve Optimizer all core. My first run was a -100mV offset. Everything seems stable after 3 30 minute tests. it never hurts to go a little overkill on the cooler and having some margin is better then bare minimum. i dont think its realistic, even if it is stable and you dont get the restarts i guerantee you are leaving You can definitely fit it in, but don't expect the temps to be amazing. ROG Strix B650e-f 7900x G. Did not changed anything else after that, letting the programme do it's thing. vCore is the value to look for. It appears that they don’t boost at all. Curve Optimizer – Undervolting Ryzen 7000 Processors. 9Ghz on the last 6 cores. I think that should be AGESA 1005 and higher. I found that I can have 2 cores at -42 and the rest are spread between -36 and -16 for stability. 7900x, in eco mode, 32gb 6000mhz ram and a 6700x. I haven't done enough testing to declare it 100% stable yet, but it passed the CB R23 10-minute test, Blender open data benchmark, and around an hour of Prime95 stress testing. Why? It's 2022 not 1992. I would suggest to use OCCT and try AVX2 large data sets Extreme setting. Cinebench was stable through the entire 10 minutes of both test. Keep in mind, any BIOS (or SW tool) before that AGESA release will not work below -30 despite what it indicates. A downside to that is "medium load boostit" can introduce crashes with some Curve optimizer offsets that are otherwise perfectly stable at stock operational frequencies (5500 MHz). I’ve just delidded a Ryzen 9 7900X and did an overclock. my 7600x only does -15 on its best and -20 on the second. I have a Dark Rock Pro 4. Sometimes, the temps will go up to 66c while launching Photoshop and it then quickly drop down to 50c. By offsettting the curve youre lowering the voltage for the curve, resulting in less heat as long as its stable. There is also an option on asus motherboards, called Dynamic OC switcher, which is a feature that can switch between a manual AMD Ryzen Master (Basic View) The basic view provides you with the ability to automatically overclock your CPU, manually control how much overclocking you wish to apply as well and give you a view of important system parameters like the CPU temperature, speed and voltages. essentially more efficient, which youd possibly see more frames in gaming but alot of it depends on your cooling as well. but i didnt trust it to be fair, it never failed me but i left it as is. I am so happy that I am not the only one with this exact setup to experience this. Never done this before my whole life but it all changed with Ryzen Master. Is that good or bad? I see a lot of people posting they can't do any offset and others saying they can only do a little. And the wattage dropped from 130-ish to 111. Config TDP + Curve Optimizer -30. SOC voltage should be at least 40 mV above CLD We would like to show you a description here but the site won’t allow us. 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. Limited the maximum wattage to 125W. am i wasting some cores maybe, but for 40 dollar difference why not get 4 more cores, 10$ per extra core added im running 105ECLK with core1:1 core2:5 core3:-5 core4:1 core5:-1 core6:3 core7:-7 core8:-5 with 2 and 6 being my best. Ryzen Master Auto Curve Optimizer settings are very optimistic and way over shoots what is actually stable. That pushes the Precision Boost algorithm to reach higher boost frequencies. PBO Curve: Per-core (-27 to -30 range -- Used Ryzen Master curve optimization with larger vcore offset until per-core offsets went slightly under -30, to understand relative differences between cores and then normalized to -30 range. 31v! So what I am doing is combining vcore offset with PBO2 curve and using Ryzen Master to optimize per core curve. Config TDP 105W/125W doesn't help much. So once again thank you so much for sharing! Just curious as a 7900x owner who can't find others, what other settings did you end up using and what mobo/cooler? I found that -27 co with pbo enabled and xmp2 was really the quickest I could get but the curve optimizer requires crazy time doing a per core PBO curves, by themselves, are not really a power reduction mechanism even if they do nominally reduce idle draw a bit. 5kh @ 4. All expertly built by my 9 year old, it was fun teaching about building computers. So first thanks to the few tips on the hardware choices, my terra build worked first time. You can use Curve Optimizer to undervolt Ryzen 7000 processors and get better performance.
