Best stability test tool?

[daninthemix]

I've had 2 blue screens on my new build in 2 days, doing different things. What's the best tool to determine whether this is because my OC isn't stable?

Thanks

i5-2500k, P8P67, 8GB Geil, GTX570, Corsaiw 650

First BSOD when I was fiddling around in FRAPS and it gave me an error message.
Second time I was playing MW2.

I just ran the Intel Burn Test 5 times. Completed in 90 seconds, each result exactly the same. Did cause the temp to rise to 71 degrees - higher than I've seen playing any game so far. But no probs.

Any suggestions guys?

EDIT: Just ran it another 10 times in a row. Temp up to 73 degrees, but still passed.

False, bare minimum is 20 runs at maximum available memory, even then that same clock could fail with Prime Blend.

There is no 1 test really that can tell you if a clock is 100% stable or not, it takes a lot of time and testing.

But the author of IBT says no more than 20!

Unfortunately I had dumps turned off. Have now turned on Small dumps so may be able to get something from the next one.

I ran the Windows memtest and memory came back clean.

BTW my VID was up to 1.3811 during IBT. Is that okay?

Just wondering if I should ditch my manual OC and let the Asus tuner do it

Yes, I am presuming it's unstable because 2 BSODs in 2 days isn't healthy.

My entire BIOS settings follow - if anyone notices anything wrong please let me know:

BCLK - 100
Turbo Ratio (by all cores) - 46
Internal PLL Overvoltage - Auto
Load Line Calibration - Auto
VRM Frequency - Auto
Phase Control - Standard
Duty Control - T-Probe
CPU Voltage - Manual 1.350
DRAM Voltage - 1.5
CPU PLL - 1.9

Anything I haven't listed is probably on auto.

Hmm just noticed I have my Geil RAM set at 9-9-9-24 when it is in fact rated at 9-9-9-28. Is that a problem?

 

[daninthemix]

Just ran 5 cycles of IBT on Extreme and passed.

It's probably best if you check those bsod dumps then you'll have a better idea what's causing it.

We're all kinda assuming it's the oc because you've mentioned it in your post but could also be the usual driver bsods. Check out those dumps with http://www.resplendence.com/whocrashed .

Thanks for that link. Installed and this is the result of the last crash dumps:

Error: WHEA_UNCORRECTABLE_ERROR
Bug check description: This bug check indicates that a fatal hardware error has occurred. This bug check uses the error data that is provided by the Windows Hardware Error Architecture (WHEA).
This is likely to be caused by a hardware problem problem. This problem might be caused by a thermal issue.

If I remember correctly that's like bugcode 0x124? aka more vcore! Personally if I was really eager for 4.6ghz I'd start at 1.38vcore and work my way down.

Yeah 0x124

Well I'm doing better now after putting my CPU multi on 45x and leaving everything else on auto. Been gaming for a few hours (And the only BSODs I saw were in games, so that's what I'm using to test) and all okay.

Fingers crossed.
