a problem in bios version 1658

[Ali95]

my motherboard is PRIME B760M-A D4 i updated bios from 1604 to 1658 but after i updated i got big spike in latency

=

BIOS and chipset behavior

The highest measured SM BIOS interrupt or other stall was 224 microseconds. This is considered poor behavior. Your system may have difficulty handling multimedia in real-time and may be subject to unexpected stutters and unresponsive behavior 

when it was 1604 it was ok latency between 10-40ms. 

i tried reinstalling chipset driver but it did nothing.

could this be a problem from bios itself?

i rolled back to 1604 but still have the issue

The highest measured SM BIOS interrupt or other stall was 227 microseconds. This is considered poor behavior. Your system may have difficulty handling multimedia in real-time and may be subject to unexpected stutters and unresponsive behavior. More info..
