So I am trying to get my system stable at 4.4 Ghz, and I decided to let it run overnight for 200 runs. Anyways, I woke up this morning to find out it had failed at run 21. I find this funny as it seems many people consider 20 runs stable. I upped the voltage one notch to 1.375 (i think) and started the test again; failed this time at run 27. This has led me to the conclusion that 20 runs of LinX at max memory is NOT stable. How many runs do others here use to test for stability for their 24/7 clock?
