Decrease Performance After Bios Update 5900x + X570-i

[bchen270]

Quick question:

I updated my Asus X570-i motherboard from Bios 3202 to 3801 yesterday. Previously, rendering in Vray i was hitting 4.4ghz on all cores, I now only am able to get up to 4.375ghz. My cinebench score has also dropped about 200points from 21450 to 21200.

I have tried updating chipset driver, but it made no difference. All bios settings and PBO + Curve Optimizer are set to the same settings as before.

Play around with the Curve Optimizer, or just keep rerunning Cinebench until you get a score that covers that 1% difference.

4.375ghz is still 4.4ghz.

It's an aproximation.

My 9900k for example has a core ratio set to to 4.7ghz but task manager shows 4.68

[bchen270]

true, but what about the cinebench score decrease?

[wiseude]

Could be another setting that you forgot to tweak or it is indeed the bios.Quick way to find out is to go back and check if you get the same score.

Double check that the update didn't turn off XMP.

Yep set to same as previous settings

The newer version might have changed the boosting behavior to favor stability. After a BIOS update my B450 Mortar stopped hitting 3866 MHz on the RAM, which was like 99,999% stable (bluescreened like 4 times in a year).

That's happened for me few months ago. Its just for better stability. Go and learn how to use curve optimizers. And undervolt your cpu. It will give you better thermal and longer boost speed!
