Best stability test tool?

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.
 
The best is a game.

Definitely and by far. Tests all aspects of the overclock, not just certain parts.
 
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.

If it passes atleast 5 rounds on standard on IBT it's a safe bet the OC is stable. 73 degrees on IBT is nothing to worry about, it's one of the most extreme torture tests your CPU can be exerted to, chances are you will never put the CPU under that much stress anyways.

Intel Burn Test is ONE of the better stress testing tools to use, but make sure to select the MAXIMUM Stress Level. I have tried lots of OCs that are fine with the STANDARD (default) test, but fail on this. Gotta be sure you know.

Good Luck!

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.
 
Well the first thing to do is download "bluescreenview" then post the images or at least the details here so we know what they are pointing towards.

I would also run Memtest, download it, burn the .iso onto disc and boot to it. Who says it's an unstable overclock?

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 :D
 
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.
 
Most likely more vcore is needed for your 2500k to do 46x stable. Forget IBT since you're passing that easy. Try linx max mem / prime small ffts / prime large fft and ofc blend.
 
Prime95 is great for stress testing. If it runs stable for an hour (personally I think 8 hours is overkill), you're quite safe.
 
Many things can cause BSOD, not just unstable overclocks. The easiest way to confirm this is to run your CPU at stock for a day, see if you get any BSOD, if not then you know it's the overclock. If not, then something else is the matter.

I doubt if you managed to complete Intel Burn Test that it's an unstable overclock.

err...

not really

my computer runs 5ghz fine in games. i put it on IBT and it falls flat

certainly not a proper stress test and very poor advice imho

again, another poor assumption.

8 hours prime is required.

either that or 20k on LinX or a good solid 500 runs on IBT

a comuter is not stable because it does a bit of stress.

extended stress is required.
my current cpu will do 4.6 all the time.
it does 4.8 with the memory loosened off and 5ghz with a lot of messing.

but the latter two will run for six hours max before giving up the ghost.
 
yeah make sure to set your ram at its rated voltage and timings just so you don't introduce more variables into play.

Try linx with max memory instead of IBT in this case as you seem to be able to pass it fine which means it's obviously not doing it's job. I'm still betting you need more vcore for 4.6ghz.

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

Just running stress tests isn't really going to tell you if the crashes are because of the overclock, or simply faulty hardware considering it's a new machine.

Take it back to stock speeds and see if the blue screens continue, simplest way really.
