Limiting pbo values helps with temps and therefore will likely increase performance a little bit more. in large data set it can maintain the whole testing period May 17, 2021 · There are 3 main limits (TDC, EDC, PTT) and then maximum boost frequency. GPU: EVGA GeForce RTX 2060. 12-05-2023 01:39 PM. When tweaking PBO, a lot of people set that to 255; does that value represent degrees in Celsius and is the default 90? I have a 5900x and I keep PBO disabled since the stock performance is more than fine for my workloads, but was curious to see what PBO potential it has, and with PBO set to advanced and PPT/TDC/EDC set to Motherboard (500/200/280), in Cinebench R20 i get multi core all clocks Jan 18, 2021 · They also have a link describing AutoOC and PBO in that article.

The default limits for 105W CPUs: 142W PPT, 90A TDC, 140A EDC. To determine the base performance from which to make your adjustments, simply enable PBO2 then set power limits to 'motherboard' and scalar to '1x'. 1 to 1. Look at voltage underload PBO will stop at the FIT limitations of 1. Spoiler: PBO Off Vs PBO ON + 200Mhz Offset (Auto OC) The above spoiler shows you there is no difference between PBO off vs PBO on vs 200Mhz offset. 775 all core to get 24000 in CB R23. In the menu that opens, select “Enhancement” from the Precision Boost Overdrive dropdown. In the bios I set PBO Advanced settings PBO Limits to Motherboard, PBO Scaler to Auto, Curve Optimizer to negative 30, 30, 8, 30, 30, 30, Boost Override to 0, 50, 100, 200; and Thermal Throttle limit to Auto. EDC: 150. TheMunyx. For my 5600X PBO it makes my CPU go up to 4. Jul 20, 2023 · Then push clocks high to 4. Pulls around 87w. • 3 yr. Turn off any performance bias boost other than PBO & XMP. Curve optimizer is configured to be per core, best 2 cores are -15, 4 best cores after those are set to -20 and the rest is set to -30. All it does is allow the CPU/motherboard to run the CPU to certain limits for boosting. 6. 300V, LLC level 4/5, PBO disabled, I get 648/4134 points SC/MC in CPU-Z benchmark v. Jul 11, 2022. Manual Thermal limit nothing happens. Boost clock offset nothing happens. PSU: 650W 80+ Bronze. PBO with AutoOC still follows the Silicon Fitness Monitoring and will be safe as long as you have adequate cooling. Curve Optimizer - per core, -25,-25,-25,-20,-15-15. Single core gets to about 4. 600Ghz attainable) EDC Limit gets broken and discarded by the algorithm and you get unlocked PBO boosting. PBO Scalar - Auto, 1x,2x,3x no difference. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. SSD: Samsung EVO 970 Plus 250GB. Wondering if anyone has experience with using PBO and curve optimizer with the 7800x3d. Hey guys, So I recently got myself a Ryzen 5 3600x, paired it with 16GB DDR4 3600 ram, an MSI MPG X570 Gaming Plus mobo, and a Cooler Master MasterLiquid 240 AiO. I suggest: Voltage = Auto. Maybe start at -15 and work down from there testing overnight with Corecycler to determine stability. Blender Average 73 Max temp 76. 88%; Geekbench 5 (single): +1. PBO is just stock operation with some limits adjusted. I Tweaker Tab---. Thermal Throttle Limit - Auto. 3%) Regardless of configuration, maximum clock speed is 4,950. : r/Amd. Dec 20, 2020 · Again, my theory is this should have allowed the CPU to work with the lower power curve allowing more frequent max boost clocks and the motherboard provides the CPU voltage offset in order to stabilize voltages at the CPU lower power curve working in tandem. Yours will be different, but that's what my average (silver sample) 5600X seems to perform best with. Skill Trident Z5 6400 CL32 @ 6400 CL28 | SSD: Samsung 970 Evo+ 1TB | Power Supply: EVGA SuperNOVA 1000 G3 | Cooling: Custom Loop 2x480mm 1 240mm Rads | Case: Thermaltake Core X9 | Operating System: Win 10 Pro 64-Bit Feb 9, 2023 · "Do what makes the experience better" - in regards to PCs and Life itself. 040V. Nov 15, 2021 · My 'issue' is the following: when using PBO, with curve optimizer set manually, tested and everything, with PPT110, TDC75 and EDC95, in mixed-load usage (gaming, opening 20 new tabs/opening the browser, using CAD) the CPU will try to perform a temporary boost to 4. These latest CPUs push the limits of performance farther than ever before. Install was plug n play on a B450 mobo, but I updated the bios anyway to get access to PBO for the chip (old Bios did not allow PBO with this Auto is disabled. Going to test PBO with limits disabled on my 3700x and report back. PPT is the power drawn from the socket, TDC is sustained current limit drawn from the VRM, and EDC is the peak current limit drawn from the VRM. However, I haven't seen better performance by setting higher limits than mobo sets (1000/114/168). Skill 3200 CL14 @ 3600 CL14-15-14-28 2T / Asus Crosshair VIII Hero WiFi (4702) 5900X PBO Advanced (220W/140A/140A) - Single core 4. ba js sa dy dg pd hr vb zj nr
