Cinebench R23: 1700 single, 22000 multi CPU-Z: 650 single, 8900 multi Temperatures never exceeds 48 C even under prolonged CPU-Z stress. If it crashes then lower it. FCLK 2000MHz. When I do my PC does not post. Tweaked the same PBO settings with the same data as before. Asus ROG Strix B650E-F Wifi gaming, Ryzen 9 7900x, Gskill 32gb of RAM, and a Sapphire Nitro+ RX 6950 XT. Out of the box, the latter feature slightly lower boost clocks and a TDP … 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. The TDP is 170W, and PPT is 230W. There is something weird going on here, in fact Ryzen master shows the max reachable frequency at 5. I then saw that you need to change PBO from "auto" to "enabled" in bios for it to appear. However, the Ryzen 9 7900X3D did improve in multi-threaded workloads with PBO and undervolting, although it remained less competitive than lower-priced alternatives. Using Gigabyte B650M Aorus Elite AX motherboard. PBO boost override disabled. Then at the bottom you can select advanced to manually adjust the PBO settings yourself. 08v. I am trying to have eco mode settings. So far I have been able to score about 30500 with my 7900x. Despite what marketing may have you believe, there’s almost no difference between the X and non-X variants. I decided to restart and load defaults in BIOS, turn on PBO Enhancement and EXPO. If the pc does not crash then keep increasing that number in the negative direction. Bought the 7900x bundle with the b650e-f wifi and the 6000mhz cl36 back in Feb and love it so far. I set all necessary steps on how to do it but I'm still getting high temps. Any Ideas why my Scores are significantly lower than before the update? Mine 7900 [non x] does 30400 also on cinebench r23 with Gigabyte B650 Gaming X AX on custom loop, without OC default 5. Cross posting this for those with the 7800X3D. Not sure why I'm crashing so much with the 7900x, and I can't find anyone else who has the issue too. The result was -30 for each of cores. then you want to turn on the PBO Scalar to 10x as this will allow the CPU to boost for longer and it will add more voltage for the CPU to boost higher. My testing ranged from Cinebench R23 to OCCT custom variable core testing. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… My specs are as follows: Asus Rog Strix X670E-F gaming wifi Ryzen 9 7900x 32 gb Tident Z5 Neo Corsair H150i RGB Pro XT Asus Tuf 4080 OC Edition Corsair HX1000i (2022) So far I have enabled pbo, set max cpu boost override to +200, and set curve optimizer to -20 for all cores. O. TDP 125W - PPT 169 TDC 124 EDC 188 TDP 130W - PPT 176 TDC 128 EDC 192 TDP 135W - PPT 183 TDC 132 EDC 196 I've been using the 130W settings for a few good months. 7 max turbo speed. 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. using a FLAT LLC means using one with minimal resistance (LLC8 on Asus boards), which means minimal voltage drop under high current loads (i. vciqj dmf nptu tnlr gylaemoc ffpewjbl fqfp ivlr bsyp jlhkz
