Ryzen performance loss in CR15

[gm-madi]

the first time i made some overclocks on my ryzen 1600 i had 3.9Ghz @ 1.3250v and RAM OC manually to 3200Mhz. so i tested in Cinebench R15.

after 20 days i made same drivers updates + bios update and i tested with same overclocking settings and performance was worst.

Those values are within statistical error and also depend on what's running at same time. Also when you see new BIOS and it says "improved compatibility", you can be almost sure that performance will suffer.

well, i have aa biiger problem now, i tryed to do 3.9Ghz with voltage set to auto but the PC refuse to boot at all.
