GA-770T-USB3 Freezing, BSOD, Random restarting

[Dark Mantis]

I would say it would be a good idea as it will be stressing the memory controller on the CPU as well as the memory. Just because you have already checked the memory doesn't mean you can't do it again.

Oh for sure. Okay well memtest will be a few hours to do both stick one at a time. I tried registering on amd website for RMA but there seems to be difficulties with that. Call center is closed today so would have to wait till tomorrow. I will check back in when all is done.

How long should I run prime95 for?

On newegg the ram tech specs says DDR3 1600 (PC3 12800) 9-9-9-24 2t. Gskill them selves say 1333mhz 8-8-8-24 and if at 1600 then 9-9-9-24. and cpu volt a +1.5. I was so confused because info wasnt a solid answer.

[Dark Mantis]

Because of the problem with AMD memory controllers being a bit weak I would advise not going over 1333 when running your memory.  Also at that speed you can run with tighter settings of 8-8-8-24 which will make it as near as possible the same without putting your CPU at risk.

Just run Prime for a decent length of time say a couple of hours or more if you can stand the boredom.

Im on my laptop right now. If I didnt have an extra computer I would be in a mental institution.

btw. thanks for all your help thus far.

Believe me I know the feeling

So tests are done,

Memtest - each stick 4 hours, 10 passes no errors.

Prime95 ran over night for 13 hours not a single error, maintained a steady cpu temp of 57C and system temp 31c.

Closed down prime and not even 2 min later and the computer restarted, and its actually stuck on a gigabyte boot logo this time. Restarted, froze at login window. Same behaviour when I play a game for a while and quit to desktop.

Well that's good in some ways in as much as the CPU, memory and motherboard seem to be fine. Your temperatures are good. PSU is obviously supplying a steady source of power.

First thing to do is disable the Gigabyte logo (obviously the computer doesn't like it ) no seriously disable it. You will at least see what is going on during the boot process then.

Maybe we will get some idea from that next time it happens.

Well i just set up an RMA with AMD to replace the cpu. I think I have about 4 weeks to do it. How exactly do I disable it. What steps should I take.

[Dark Mantis]

There should be an entry in the Advanced BIOS Features called Full Screen Logo just disable it.

[biggyk]

So you dont think its the cpu anymore?  I took the cpu out but I can put it back if you want to test out more things. My issue now is I had to wipe off he thermal greese that was preapplied to the heatsink onthe cpu to get the serial number. I dont have any greese.

[Dark Mantis]

Well I wouldn't have thought so. If it will run Memtest86+ and Prime95 blend for hours on end without a problem I would say that proves the CPU including memory controllers is ok. Although we are getting a smaller and smaller list of possible problem components.

[biggyk]

SO im just wondering it is fine to put it back in, the grease that came on the heatsink was transfered to the cpu and I had to wipe it off. Not sure if Is safe to put back in.

[Dark Mantis]

No you will need to apply new thermal compound before refitting the heatsink. The old stuff must be completely cleaned off both surfaces first though. If you would feel happier RMAing the CPU first no problem.

[biggyk]

Well I can always probably just go buy some more if I need too. What other tests or ideas did you have. Like I said I have like 4 weeks to send it across the country.
