Any ideas?

I should be stable.

Should I raise vcore? Ram timings off?

that far in, it's harder to tell

run it again first, and if it fails then see below....sometimes it just hiccups

how where your temps? if they're OK, raise vCore 1 step and try again

If you dont feel safe, try prime95 over night and see what happens.
I'm happy with it. Just I prefer being stable as possible. I'm not doing much CPU intensive as of late. I just like having a faster responsive comp

Those Gflop numbers look really low for 3.6 GHz, maybe it has something do with Nvidia chipset. On P45 board I get readings like this with Q9550

i think you just need to up the vcore a little bit
my cpu is stable 24/7 at 1.32v, but at 1.31 it fails intel burn test within a few minutes

I'm like 3 notches from 1.4 for vcore
But any higher makes my system fail linx within minutes. Couple lower, same results. Might be the nvidia chipset

yea i guess it is most likely your mobo. what speed and timings do you have set for your ram?

Stability is always relative. If you're satisfied with it, then it's stable enough. I've had a LinX error on my 99th run before and it bugged me out, so of course I had to tinker some more..

I'd start by bumping vcore one notch and seeing if it takes longer to fail.

Yeah, i agree. I had it stable at 50 runs and it freezing up on me. But i was off by a notch.

Just did a IBT run. 50 passes at maximum stress. I'm Stable. I'm guessing it was a hick-up.

I wouldn't call passing 50 runs, after failing on run 49, stable. It could have failed on 51. I'd try at least 100 runs. I've had failures all the way up to 130. I've passed 150 runs and then crashed/BSOD'd while browsing the internet hours later.

It's not stable until it's stable. There's no such thing as a hiccup. Your CPU gave you a wrong answer. Stable systems don't do that in only 2 hours. Two weeks, maybe, but not two hours. Any system will throw an error eventually, but those errors should be exceedingly rare.
