Adjusting Asus Zen3 processors to higher speeds
Adjusting Asus Zen3 processors to higher speeds
Wait a minute, I just realized you're running a 5800X3D. That makes a bit more sense now, I could've sworn you wrote 5950X in there at some point, I'm guessing I just went full dyslexia and mixed up 6950 XT with 5950X. that score makes a lot more sense now. Ok, so it's still likely a misconfigured PBO setup (the X3D is pretty much immune to memory settings as long as the Infinity fabric is clocked well enough). Unfortunately, I don't know where the limits are optimal on a 5800X3D, so I will need to do a bit of searching to find that out first. I'll go through the data though when I get home and see for certain what's going on.
I finally had the opportunity to examine it. The CPU isn't increasing its speed at all. It's stuck at a steady 3.6GHz, with no cores exceeding that frequency. When PBO is enabled, it should be reaching around 4.5GHz or more, so 3.6GHz is just the base clock. The temperatures are normal, which means it should be operating much faster than it currently is. That should explain the low score. The main question now is why it's only running at 3.6GHz. First, I'll check the BIOS settings to confirm the multiplier is set to auto and other relevant parameters like turbo boost. I’ll review the logs more closely to find a better explanation, but I might start by resetting the CMOS and beginning fresh.
I had tried the "set to default" setting in the BIOS before, but it didn’t work. Your advice helped me explore the BIOS more thoroughly. Surprise: performance is returning to normal. I switched to the "Optimized default" state instead of the standard setting. Then I repeated the same steps from my first post—turning on features like PBO and AMD Smart access memory—to see if it would help. It worked! (I had to revisit it once more and re-enable AMD Smart access memory.) The CPU is reaching its MHz limits, but temperatures remain comfortably under 70. I’m planning to experiment with PBO2 now to push it past 20k.

Great! If you're interested in pushing performance further, 6900 XTs and 6950 XTs can be significantly boosted with proper overclocking. Unlocking their voltage scaling capabilities is manageable through the operating system. On my setup with the 6900 XT—though it has some lower-quality silicon—I've managed to raise its score by over 1000 points in Time Spy Extreme GPU. The 6950 XT offers more power out of the box, so you'd likely see even greater gains, though I wouldn't expect as much from it. That said, these improvements are mainly for show; aiming for 21,000 points or more isn't usually worth it. Still, if you're up for it, I can share some tutorials to help you achieve a solid performance boost.
For power restrictions there are two choices: manual or MorePowerTool. If you choose manual, follow this guide. For MorePowerTool, download the 6950 XT vBIOS (any version works, just pick what fits your card). Install MorePowerTool and select your 6950 XT from the options. Adjust Power Limit and TDC limits to high values (800 is sufficient). Save your changes with Write SPPT. To increase voltage, repeat the same steps with MPT, then refer to this additional guide. Restart your system each time you save a SPPT for it to apply.
Stay tuned, it's interesting to see how much you can go with that card.
