How many hours if Prime do I really need? - Page 6

post #51 of 126
Thread Starter 
I see, but how would i determen if it is a DRAM voltage-issue or something with the memory controller?

But I don't need to run prime95 for 15 additional hours just because I increase the vcore?

That`s why I allways recommend in my posts to people to run P95 LARGE FFT for at least 6h (12h is ideal) and if it passes then 20runs of IBT with MAX RAM for Vcore stability..

I dont recommend P95 SMALL FFT as IBT does better job and faster too..

EDIT: You don`t need to run P95 Small FFT again,just add more Vcore and run IBT again..

CHEERS..

Should IBT use 100% CPU during all 20 runs? Mine seem to go down to 50% after the first run..

Yes it should, it will probably error out if you don't get 100% utilization.

IBT can miss subtle errors where one your cores runs an error in P95. I recomend running 3 runs of IBT at Max and if this is passed 12hrs small ftt, 12 hrs large ftt and 24hrs blend(36hrs personally.) After this point I feel I am as stable as stock.

So what should I do then? It just uses 50% CPU, even more vcore? Could it be something else than the CPU?

Is your core affinity set to 8? or is it set to 4? that would be the simplest solution, one of those mistakes we all make

IBT doesn`t load CPU 100% all the time as load per 1 run drops and again shoots to 100%..
