[Buakaw85]

Hi there

I have new rig and components are next
motherboard gigabyte z170x-ud3
ram:corsair vengeance lpx ddr4 3000mhz 16bg
GPU :kfa2 gtx 980 SCO gaming edition 4gb
Disks: samsung evo 250 gb ssd + 1 tb
proc: i5 6600k
XFX xtr 650w
and 3 additional fans on case
monitor is benqxl2411 144hz


Problem is next when in windows 7 all is working fine at 144hz aplications and sutff (desktop) but when i lunch somg high ende game like Tomb Raider or WoW it works fro like 20-30 mins top and than i got crash nifo or hard reset even.
So iw done some stress tests whit Kombustor, Furmark, and orthos
and all works fine 0 errors or problems.
Reinstalled whit DDU graphic drivers on fresh win installation
checked cables from monitor and in case
Temperatures on gpu are max 83

so my conclusion si next it culd be PSU when i play games it simply doesnt have enught juce to run it at 144hz(iw read that to 131volts consumptions for to run it at that refreash rate)

so i rly dont have any clue anymoar so any suggestion wuld be nice ty onwards for ur time

Your monitor refresh rate has nothing to do with power supply. Your power supply is plenty for your system configuration. I would check your CPU temps as well. 83c is a bit on the high side. I have a GTX 980 sc, myself, and I do not see temps that high, even when pushing the card, running folding @ home.

Hmm was dealing last day whit my temps on gpu was lowering preformance in game but temps are down to 68-75 tops still get crash here and there it might be this problem whit termal paste on gpu culd be burned need to check that but on the other hand this is strange when still in game game runs fine i monitor stats but when i move and play like 10-20 mins sunndenly frezz and stops working dunno what is this problem

Sitting still, you are generally not using as much GPU power, as you are moving around. I have seen the clock speed of my GPU lower just sitting still somewhere vs running around dalaran, for instance.

I know what u mean even so i dont get why i got crash on low preformance but thats like after 1h or so,... rly i dont know anymoar what culd be problem culd be false hardware
