Occt

[Negotiator]

Ok, some guy on here said that this program only tests cpu stabilty, so does that mean if my oc stays stable that both ram and cpu are stable?

[vapb400]

I believe it tests both. DL and run memtest to verify though

[Negotiator]

so if i test my ram on memtest and it is stable for over 12 hours, then I test on prime or occt, and if it fails I can conclude the cpu is failing, is this correct?

[vapb400]

i have found that occt errors out when i could still prime/sp2004 for 24+ hrs. But yes, that is usually an assumption you can make.

yeh, but often the cpu can show errors in memory tests ;)

I usually test for these things seperately. If the memory is not stable, MemTest for Windows will usually pick up on it quickly. I wait until the memory is completely stable through a few passes of it, then will go on to Prime95's Small FFT test to see if the CPU is stable.

I never even heard of OCCT though..

OCCT tests memory too.

Running Prime Small FFT is not a good idea, custom test will find errors much better.


This is how I test and it always proves to be stable

OCCT -> 3d mark 05, 06 including cpu tests! -> UT2k4 1-2h+ or any other OC sensitive game ->
Windows memtest 20-30min and SP32M -> Prime custom, min FFT 1024, memory to use 80-90% of total RAM, 2-3h enough but more is better

Usually only first 2-3 tests are enough since if I can pass them then most liekely others will pass too.

OCCT seems to be very sensative, even more than prime. It's definately a good system test (memory and cpu stability). If you want to be secure about the overclock you should probably do all three of the major stability tests...... superpi 32mb, prime, OCCT.

Becuase I use dual core CPU's - I run superpi 32m one one core and OCCT on the other, then restart and swap them over to run on the other core.

Great stress test for dual core owners - and allows OCCT to provide true temps when both cores are fully loaded and you check the voltages while both cores are pulling through 100% power requirement.

You can run 2 instances of OCCT :D
