Random freezes - maybe RAM? Faulty components?

post #1 of 16
Thread Starter 
Lately I've been getting random freezes with no BSOD. Usually in games, but occasionally just while browsing the net. A few days ago I decided I'd had enough of it and I got to work. Current OC settings:








Prime95 seems stable while testing with small FFTs, but gave me an error on the first worker after about ten minutes using blend. Tried it again and didn't give me any errors for the hour I let it run. Booted into Memtest 86+ 4.20, using all three RAM sticks, and after about an hour it gave me an error. Went into the BIOS and upped the VTT to 1.6v, ran Memtest again and it didn't report any errors for the twelve hours I let it run. However, the random freezes remain.

Tried Linx (Never have before to be honest), and it freezes with no BSOD after ~10 seconds. With or without "All" enabled. Am I looking at an unstable OC or faulty RAM?

Unstable overclock, I would raise the voltage for the cpu higher to get it more stable.
Are you also monitoring your temps while using Linx?
They get high really quick and can cause problems.

Yep. Doesn't spike if that's what your thinking, kept Core Temp open every time and it didn't seem to go above 41c. Which I find a bit odd considering it really doesn't raise my temps at all.

Well, unless it spikes so high so fast that it freezes my CPU before Core Temp can even reflect the change.

ur QPI voltage is really high !
anyone correct me if im wrong.
post #5 of 16
That type of voltage on his specific RAM is alright.
I would set RAM at stock and focus on getting the CPU stable with a step or two in voltage. Then another round of Linx.

My RAM is at stock, actually.

Upped the voltage to 1.325v, doing another Linx test now.

Eight seconds, bumped it up to 1.337v, testing again...

Eight seconds again. Up to 1.36v, testing once more...

Nine seconds. Testing it at 1.4v. If it fails again I'll do a run at stock settings.

10 seconds. Testing it at stock...

12 seconds at stock. I'd say something's up.

Linx problem's solved, I'm a dumbass; I had its priority at real-time instead of normal. Now it crashes after about five minutes instead of five seconds, hehe.

Take 2 out, boot back into Memtest and let it run a while. I'd say 2-3 passes on each test should be sufficient. If that stick of RAM works, yank it out, put 2nd one in, rinse repeat. If you find one of the sticks to be faulty, leave it out, and boot up into Linux with just the other two sticks installed. If you get at least 3 passes on each test on each stick of RAM, then I'd say it's just a timing issue. Try backing your CPU overclock down a little bit, see if that helps. Also, anything set to AUTO in BIOS, I'd manually set if I knew the correct values. Sometimes AUTO likes to be a little punk and mess things up.

Yeah, that's just what I was about to do. Linx (to clarify, I'm using Linx the stress testing application, not Linux) no longer crashes my system at all now, but it does stop due to an error after about nine minutes. A worker in Prime95 will also stop due to an error in the Blend test after about 10 minutes, but the Small FFT test seems completely stable.

So that leads me to believe my processor's fine, I just have to work on my RAM now. As you said, it's probably a timing issue.
