How long should I run Prime 95 to stress test for stability?

post #1 of 22
Thread Starter 
Hi,

I'm relatively new to Overclocking compared to many here!

I have been running Prime for the last 3 hours (and a little more) and the temps seems to be in the 60's (max) and CPU is at 100% load for the entire duration!

Here is a screen shot with all the relevant info:
375

How long should I continue to run it, or can it be assumed it is stable now, does the test ever end?

Also, only 33% or 40% of my 16GB RAM was used during the test (is that a problem), should I use 100% of my RAM as well?

My vCore is at 1.32V is that too high or is it good?

Thanks for all your help in advance!

The details of my rig is in the signature (The Phantom)!

Test doesn't end. I run Prime Blend for around 8-12hours before I think its stable. Those volts and temps look good.

8-12 hours is good. 24 hours is better

Wow ... that long guys! I was hoping to end this before going to bed tonight!

Is Intel Burn Test or LinX faster, can I stop this now and run that, or run 2 simultaneously?

how about the RAM should that be 100% utilized or are the current levels faster?

I'm not trying to be hasty, but if there is another test which would let me know the OC is stable, is there any harm in running that instead or Prime? Or is Prime the best test to stress test on?

Thanks for the answers!

linx is a good test 3-6 hours but prime95 is best for 12-24 hours to really work out your system after those 2 tests your golden! Forgoe the inter burn in test I just use that as an initial test but the other 2 are more accurate in testing ability for cpu heavy programs and gaming.

Hmmmm...so I guess P95 for 12 hours at least ..eh?? That's just too long?

If it crashes when I'm not there, would I be able to go into some kinda logs and figure out why it did? Does P95 have any logs to check why the system rebooted?

I generally set it to run overnight. The log is called results.txt.

outputs passed or failed for each test something like this.
