Ohhhh I'm glad it's decent. I have done 20 runs of Intel burn in but ultimately using AIDA64 which I have run for 3 hours so far with no issues.
How long should I stress test for? I'm not into the whole 12 hour testing etc. if it's stable for a few and in everything I do, that's normally good enough for me.
I have only changed core multiplier, vcore voltage and XMP for my memory, the rest is on auto
