Got this result on my XPS 15 9570.
Resetting the time frame does not set it to the current value , so I guess the calculation for the average is bugged?.
Same for me. I´m rounding to full MHz and sometimes the numbers are off by 1MHz +/-.
(But all at once either plus or minus)
When I restart the program, it is fixed most of the time.
Spectrum Spread is disabled and the bus clock is shown correctly ;-)
I use the PBO2 curve optimizer on a Asus...
On the Asus ROG Strix X570-I Gaming mini-ITX, the power deviation averages 97%.
BIOS 1407 AGESA 1.0.0.4
I run a R5 3600 and the Infinity Fabric at 1800 Hz to match the speed of my G.Skill 3600 CL15.
Stock cooler and embarrassing 3975 Hz max at 72C CPU temp on a "pre cooled" (all fans on max)...
