New build, screen freezes up

post #1 of 5
Thread Starter 
Sup all;
I've recently built a new rig and having some random freezing issues. Can't pinpoint it yet.

Current rig:
Original PSU = ANTEC EA650, now Corsair RM 750
Intel i5 4670k
ASUS Z87 Pro mobo
I've tried two sets of rams (Kingston brand), both @ 1333, one rated at 1.5v and another 1.65. One set = 8gb while other is 4gb
Tested on original GPU GTX 560 TI, and now GTX 770.
SSD


What happens is while playing Arma 3 game randomly freezes and PC locks up. Weird thing is when i am playing and TeamSpeak is running, i hear it still running in backgroup as if i got booted from game only. But my screen is frozen on a game frame. ALT+TAB brings me to a black screen and gets stuck. No other keys register.

What i've tried:
Monitored both my GPU and CPU temps and the highest ever recorded has been 70 for CPU and about 65 for GPU. I've done a **** load of stress tests and PC doesnt seem to lock up only randomly during game play. I now got windows event viewer to start tracking next.

BTW i have a new set of ram coming in different brand in case it still is ram related. I haven't tried reformatting yet but might be my next step frown.gif

I've done searches for the past few days and people mention either overheating or RAM issues. I dont believe its an OH issue, ram possibly though... Any other tips i can look into or try to find out where it crases? The stress tests monitor files and game reporting file doesnt tell me anything. Thanks all

can try adding Cas latency to the Ram, if they are 9,9,9,28 try something like 10,10,10,32
, or declock it down a little from 1333 then again I really dont know biggrin.gif

Good point. Weird thing is on the old ram sticks i delocked it from 133 to 1066 or something similar to whatever option the bios gave me. Right now i've changed it to the XMP profile on the new sticks. The CL is 9 on the stick...but per bios its showing as 7? I guess i can manually change these back to 9 or higher? Do i just change the rates for each # 7 back to 9 or higher? is that all?

I'll add that i updated to the latest bios and have the latest drivers for mobo and GPU. Thanks

I would manually set the speeds, and yes also look for a bios update.

I would set all 9's and move down if they are stable.
