Ryzen 7900x curve optimizer reddit

Ryzen 7900x curve optimizer reddit. Current Setting: I am currently running my Ryzen 7950X on 105w eco mode on Bios with -20 on All Core with curve optimizer. It appears that it's not enough. You're better off doing curve optimizer the old fashion way. 97v, its an asus tuf b650m-e and klevv cras v rgb 6000 cl30. It appears that they don’t boost at all. Each core has multiple V/F curves that vary depending on load on the CPU. With Curve Optimizer -30, it's about 7% higher than stock 65W PBO settings. 0) : Amd (reddit. 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. essentially more efficient, which youd possibly see more frames in gaming but alot of it depends on your cooling as well. I have a Dark Rock Pro 4. It's Ryzen 9 7900X. I think I am out of options. I found that I can have 2 cores at -42 and the rest are spread between -36 and -16 for stability. 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. but i didnt trust it to be fair, it never failed me but i left it as is. 7ghz, 1-0. With ECLK, we still build on the factory-fused VFT curve but adjust the frequency by adjusting the reference clock. 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. I too came from Intel to amd and was shocked to see the idle temps like this but yes it is normal I guess. im trying to run the optimizer for my ryzen 7 5800x. 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. That pushes the Precision Boost algorithm to reach higher boost frequencies. 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. 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. I have also Jul 26, 2024 · As shown in OC Strategy #3, Ryzen overclocking is typically done with a negative curve optimizer. 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. the 5000 series boost algorithms favour lower temps, so lower temp can equal higher boost freq, at the very least higher sustained boost. 7 GHz. 3 - 4,4 Ghz (Blender) without even touching any EFI setting except XMP. Lately I've been toying up with PBO2 with my 5600X. Ran both per core and all core curve optimizer in Ryzen Master and both came back -30 for all and per core. 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. Everything seems stable after 3 30 minute tests. 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. With the advanced boost curves these CPU's have, manual voltage adjustments are only really useful for static manual clocks. The PPT/TDC/EDC settings of the PBO Enhanced Mode can be seen via Ryzen Master. I’ve just delidded a Ryzen 9 7900X and did an overclock. 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. I am so happy that I am not the only one with this exact setup to experience this. AFAIK, ryzen 7000 series are made to work at 95 Celsius. 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. I read the guide from katalysis (Guide: Zen 3 Overclocking using Curve Optimizer (PBO 2. I have a Corsair H150 AIO and I adjusted the fans so that they have a flat curve until it hit 65C. So you ideally need a curve that works in multi and single load scenarios. 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. Each step is around 3-5mV. Ryzen Master per-core curve optimizer recommended -30 for all cores. but before this, i ran -30 all core. it never hurts to go a little overkill on the cooler and having some margin is better then bare minimum. Curve Optimizer can be found in “OC\Advanced CPU Configuration\AMD Overclocking\Precision Boost Overdrive”. Curve Optimizer – Undervolting Ryzen 7000 Processors. 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. 4! The boost also went up from 5. to check of instability. I would suggest to use OCCT and try AVX2 large data sets Extreme setting. The only setting I've really done is enable AMD Expo, and adjusting the fan curves to how I like. I tried with ‘per core boost boost clock limit’ option, by limiting these cores to ~5. I think that should be AGESA 1005 and higher. I also believe it's disabled for x3d CPU's. 0 GHz, but as soon as I launch an all core test, cores 3 & 10 stucks at 4. My System: CPU Ryzen 9 7900x. Sometimes, the temps will go up to 66c while launching Photoshop and it then quickly drop down to 50c. And the wattage dropped from 130-ish to 111. 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. My workloads typically run lots of VMs which are relatively busy and would prefer to keep noise to a minimum. Cinebench was stable through the entire 10 minutes of both test. Also, it’s normal to have one CCD slower than the other. So be sure to set aside some time, but it'll be worth it. A good cooler makes a HUGE difference. (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). Just scored 29000 (exactly 😁)This is an air-cooled (be-quiet Dark Rock Pro 4) 7900X on a MSI MPG X670E board. Even with the curve optimizier in the DUO 16 we aren't hitting max possible performance in the 7945HX. Hi, I am fairly new to overclocking. 9Ghz on the last 6 cores. Why? It's 2022 not 1992. I am currently running an ESXi server on 5950x (with 128GB ram) and I am wondering if it is worth upgrading to 7950x. As 125W + Curve Optimzer -30 applied, the Cinebench nT performance is close to stock Ryzen 7900X. Single core stayed the same though out stock, 105 and 125 watt eco mode. 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. Did not changed anything else after that, letting the programme do it's thing. 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. I want to ask about this Ryzen tool that is supposed to automatically curve optimize. 7900X + Gigabyte B650M + 32gb G. I already used curve optimizer in BIOS (I set mine to 15) but, it barely help. 5kh @ 4. Keep in mind, any BIOS (or SW tool) before that AGESA release will not work below -30 despite what it indicates. My 7800x3D was idling around 55c and now idles around 45c. 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. Chose to test per-core and after a hour of testing it came back with a -30 on all six cores. When using Curve Optimizer I noticed that average vCore drops but maximum vCore goes up, because it will boost higher. Temps are 95 stock 70c 125watt eco mode and 60c for 105 watt eco mode. 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). You can use Curve Optimizer to undervolt Ryzen 7000 processors and get better performance. It's a lot of trial and error but you may be able to work a bit more around the edges. 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. Increasing negative value for cores 3&10 with Curve Optimizer doesn’t get any temperature reduction. Started at -10 and increased by 5 after each test. 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%. Config TDP 105W/125W doesn't help much. You can however play with Curve Optimizer (CO), and set a negative offset for the cores. 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. . Maybe a better cooling solution could eek out a bit more performance, maybe. Both the 7900x and 7950x are happy with any proper large tower cooler or good aio. my 7600x only does -15 on its best and -20 on the second. All expertly built by my 9 year old, it was fun teaching about building computers. 500 points. Enable Precision Boost Overdrive and then enable Curve Optimizer. 4 to 5. Undervolting means you will have instabilities at low clocks not at high clocks. 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. 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. A quick Do the curve optimizer, it will lower temps. but it shows me it takes 11 hours and 30 min to complete. 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. 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. 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. ) PBO PPT/TDC/EDC: 95W/85A/120A A comment on a small part of this. 29v to 1. Tried with Curve Optimizer (negative 30) to see the performance change. SOC voltage is the voltage to the integrated Memory Controller. :-) take care! I don't think tuning curve optimizer on a single core basis is a great method for finding a stable curve. 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. And I'm still trying to work on that. PBO with curve optimizer (manually tested over months) gets me to like 4,5-4,6 ish. Have a quick google about Curve Optimizer first and then go and have a bit of a play with it. The scores in Cinebench R23 are +- 28. Ryzen Master Auto Curve Optimizer settings are very optimistic and way over shoots what is actually stable. Hey, i just got a quick question. It's tedious and long but it's the only way to guarantee stability. 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. 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. It’s faster than stock Ryzen 7700X too. 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). The one in optimum tech seems to have used curve optimizer and something else. Considering CPU temparature and Cinebench R23 performance, it looks 105W/125W Config TDP is good for my system. For example: On my Ryzen 5900X I get a All core 4. 1Ghz on the first 6 cores and 4. We extended the Curve Optimizer range with the release of the 7000x3d CPUs. i also have zero knowledge/experience of tweaking ram/cpu in bios or even in ryzen master. As the table shows, with 95W Config TDP, Ryzen 7700 is 3% faster. Never done this before my whole life but it all changed with Ryzen Master. i really wish i could get your hashrate but unfortunately my motherboard and ram are different and im just getting 16. Apparently the Ryzen 9 7900x has this big issue of CCD processing. And I ended up lowering the negative offsets from what RM set, while testing each core, trying to find the best results. Would like to tweak it per core and needs your help / guidance. My first run was a -100mV offset. Did a quick test on Ryzen 7900 with different PBO settings and Curve Optimizer and see how the performance scales and CPU temperature. Limited the maximum wattage to 125W. 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. By offsettting the curve youre lowering the voltage for the curve, resulting in less heat as long as its stable. I tried it, just to get a rough idea of what negative offset values to aim for. 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. However, Cinebench works I just finish building a PC using a new Ryzen 7900x CPU. 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. This is kind of expected, just be aware. ROG Strix B650e-f 7900x G. 31v! So what I am doing is combining vcore offset with PBO2 curve and using Ryzen Master to optimize per core curve. 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. Multi about the same after lowering the curve optimizer but single threaded performance went up. In games, 4K max settings, my 7900x keeps staying around 90-95C. 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. 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. 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). It sets too high values and sort of guesstimates like Hydra tool. Auto curve optimizer is not reliable. 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. Reduced vcore offset accordingly. Setting curve optimizer to -35 decreases the max single core to 5400Hz and max full multi core to 5250Hz. vCore is the value to look for. When I am looking at the frequencies, they are up to 5300MhZ for CCD1, and 5150 for CCD2. The AI optimizer recommended an all core -42 for me which I thought was insane. The processor is running at 5. I’ve gotten these numbers using Cinebench r24 and observing with hwinfo64. 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 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. Config TDP + Curve Optimizer -30. 7900x, in eco mode, 32gb 6000mhz ram and a 6700x. 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. CPU Cooler Artic Freeze II 240mm AIO. This increases performance and reduces power usage - it is basically an efficiency setting. Until now I’ve done the following: Adjusted the curve optimizer magnitude to -15. 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. Currently running (5600x) Auto OC + Curve Optimizer all core. Also spikes in temps are normal. After I had been working with the Curve Optimizer for some time. So first thanks to the few tips on the hardware choices, my terra build worked first time. 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. ycj ahoqs hlmzz rsqwl pedfm gaso yrba dzxppg rkwicu zbdwmw
