hi guys. my boss bought an amd 2990wx system
aorus pro x399
64gb corsair lpx 2666Mhz
antec 850W Psu
Arctic Freezer 33 TR
now i am having performance and stability problems with this setup.
stability wise when i setting the ram to XMP profile to work at 2666 Mhz I am getting black screen after few min of rendering no matter what.
at 2133 mhz i can render and work and get black screen after 6 or 8 hours only… and some days not getting at all.
performence issues - when i check the CPU mhz speed with ryzen master softwere i can see that when i render all cores are going down to 1.5 Ghz only… when the computer is doing light tasks the peak cpu speed is up to 3.8 Ghz.
in ray benchmark i am geting 20000 score.
is it normal? i thought that all cores need to run at 3000 Mhz at least…
1.5 sounds very low.
i am thinking of telling my boss to replace the cooler and MB
but the shop that he bought it from telling us that the cooler and mb should work fine with 2990wx and maybe the problem is in the RAM.
but they dont want to give warranty to 2666 speed because they dont allow us to change nothing at the bios.
can u guys give me some feedback on if 2990wx is working normal at 1.5 GHz all 32 cores? when rendering?
