Pc shutdown while gaming even after new psu

[nabilelmjati]

Hi guys u need some help.

My build is as follow

I7 4790k
Msi z87 g45 motherboard
Gtx1080ti
Gskill tridrntx 2400 4x8gb
Evga 750 g3 supernova

I had this build for a while with a corsair 1600 16gb ddr3 and a bewuite 550w psu. I uograded my ram to the tridentx 2400mhz 32gb. Weeks later i noticed that my system will shutdown randonly while gaming. Sometikes even in gaming menus. It happens once in a while.

When it does shutdown it tries to restart few times before it posts.

Checking the temps i see everything runnung nornally. No overheating
Under load the cpu reaches 72c while gpu 74c. This is while gaming at 4k.

I immediatly thought it was the psu knwoing the quality of bequiet. I went ahead and upgraded to an evga supernova g3. But problem still occurs.

I updated the g45 bios thinking it could be the ram being incompatible but still same issue.

Could the tridentx 2400mhz be incompatible with the motherboard? I tried the xmp both on and off and that didnt help.

Any ideas what can cause this? Can ram cause random restarts with no bsod? I only noticed that paint and photoshop run slow even though i have 32gb of ram. Moving canvas around drags and jitters a lot.

I also forgot to mention that i ran memtest and the memory itself seems error free.

if you ran memtest86 without issues, then your memory is ok.

Does memtest also shows memory incompatibility?

i've had this problem a while back as well.
The solution for me was to up the voltage of my ram a bit (.005) that worked for me and had no more problems after that.
