Hi everyone, I was tinkering with x870E Apex with 9800X3D and one time I tweaked the dram settings, it didn't post so I tweaked it back and saw a performance reduction in general. It still boosts properly but I don't know the issue here. Cleared the cmos, didn't fix.
I was trying to get better performance at Pi-2.5b. I was getting 47~ish seconds but now getting 54 seconds at the with same settings. Here are the results, you can see the clear reduction in the performance:
Here is the Aida with zen timings:
I never pushed voltages so hard and the chip is only a week old and restoring the bios settings should've restored the performance but it never did.
Any help is appreciated.
Edit: I upgraded Mobo+CPU+Ram from an Intel system and didn't reinstall the OS. Everything was fine though, that's why I didn't think it was required but I don't know why this happened now. I installed chipset drivers.
Resolved: For anyone wondering,
When It failed to post, it posted in safe mode. I checked extreme tweaker and all my settings were there which made me think I didn't lose any bios settings at all which was wrong.
To be honest, this was my experience in the past but I guess it is different now.
Settings in AMD CBS/ AMD PBS/ AMD Overclocking sub pages were completely reset to default. I'm not sure if this is a bug or intended behavior. Sounds like a bug to me. I set my previous settings back, it is fine now: https://imgur.com/a/jQhRhha

Likely your FCLK is error correcting.
Also did you stress test at 1.2V vSOC at 3200 MCLK? Most Ryzen chips will struggle to hit 3200MLCK at native 1.2 vSOC
By didn’t post, do you mean it didn’t post at all and you had to clear CMOS, or you got a “posted in safemode” screen and then you went back into bios?
If it was the second, your bios could have reverted a bunch of settings back to Auto even though most of the options within the Tweaker menu are preserved (causing you to think your original profile is still loaded). If you changed the unstable timings and saved over your profile, you could saved all the reverted settings.
your read values are low compared to your write of the ram, was that also the case before the reset?
Possible timings to tight, loosen off and see if you get performance back. My new apex arrives today cnt wait to start tinkering
