7900x pbo settings reddit

7900x pbo settings reddit. 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. Here’s the key settings: Limiting PPT as shown in the above table Using PBO / crv optimizer, set to -50 offset (works fine at low PPT’s) Setting V SOC offset to -0. That, combined with setting a per-core max boost clock of 5850 on ccx0 and 5500 on ccx1 allowed me to enable Medium Load Boostit with full stability on my 7900x. PBO Scalar: Auto. All CStates enabled manually, nothing left to auto. 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 CPU The 7900X3D was significantly slower than the vanilla 7900X in heavily-threaded workloads, with the cheaper Core i7-13700K often outperforming it. But no matter what settings I adjust under the PBO in the Advance Tab nothing got changed. EDIT: the best way to indirectly "undervolt" these CPU's, is to limit wattage using PBO I guess. RAM XPG Lancer, RGB, 32GB (2x16GB) 6000MHz, DDR5, CL40 - AX5U6000C4016G-DCLARBK We would like to show you a description here but the site won’t allow us. I know this is counter-intuitive for Ryzen overclocking, but try a small positive offset of between 3-5 on your weakest SP rated cores. I'm following the guide from Optimum Tech. Oct 3, 2022 · Precision Boost Overdrive (PBO) allows the processor to run beyond the defined voltage values to the limits of the board, and allows it to boost at higher voltages for longer durations than default. I went into advanced mode to change my PBO settings to manual, also did the optimizer to Negative, all cores and set at 30 and 20. That's why we use PBO and core optimizer, as these are the tools provided by AMD to alter the VID/Frequency curves of your CPU. PBO enhanced mode is a pre-set option in the BIOS. I manually adjusted the PPT, TDC, edc and hit save and restart but its not changing anything. It's just when pushing your architecture to its limit with factory voltage settings to account for Silicon variance, voltage increases drastically and amperage linearly. I changed stock settings to manual pbo, with 128,95,125 limits, that got 28,003 in cb r23, then I tried asus enhancement and limited to 80c, it gets higher cbr23 scores and same fps, higher wattage and lower vid max than manual settings in mw2/wz2 it stayed in the 60's c hitting 76c on a 360aio while boosting to 6000mhz My 7950X on Kraken Z73 idles at 40C and hits like tops 70 in Cyberpunk with +200mhz OC on Ultra + RT. On third auto-run on default BIOS, it lowered my curve to -30 all core And applied 200 mhz OC. Set a negative frequency to cap your single core boost, this doesn’t affect your all core boost for the most part since all core boost is so low in comparison. Cross posting this for those with the 7800X3D. Jayztwocents did a vid where he showed that the x670 boards( the exact model the used escapes me) have the backplate like all mobos, but instead if unscrewing the four screws that usually hold the mount for the cooler and go trhough to the backplate in order to install a new backplate, there are also four extra screws which go into the retention system for the cpu. 7900x on 65w eco mode could give better results due to better binning, so it's you're choice. 4GHZ with PBO On [Default Motherboard PPT EDC TDC settings] and Curv Optimizer set to -20 all cores. You can manually adjust these 3 settings. My system is pretty damn quiet, temps seem fine. The PPT/TDC/EDC settings of the PBO Enhanced Mode can be seen via Ryzen Master. For those interested, the board is an Asus ROG Crosshair VIII X670E. Hi friends!

Here are my PBO Settings: PPT Limit: 88000 TDC Limit: 75000 EDC Limit: 150000 Platform Thermal Throttle Ctrl: Manual Platform Thermal Throttle Limit: 85 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. Enabling PBO on the non-x 7900 will bring the power consumption to the same as the 7900x, while also giving the exact same performance (in fact, the 7900 with PBO actually beats the stock 7900x by a tiny bit in some workloads). fTPM, Proton, etc. After, use curve optimizer if you have the patience to find per core stability to undervolt within those new PBO limits. Unlocking stock PBO limits is a quick and safe way to boost the Ryzen CPU frequency and performance, compared to manually overclocking. Best is you go to your Bios and set the max. That should give you pretty close to the highest clocks you can get with PBO (PBO has it's limitations and it will radically limit your CPU performance because it simply overvolts the CPU), if your cooling keeps the CPU below 80-86'C tdie with the above settings, you can start to increase your EDC until the EFFECTIVE clocks start to drop. 6GHz. temp throttle to 80 degrees.
