I have prime95 going and if I put a custom setting on to test the ram at 7600gb because windows uses 400gb it locks up on me.I have 8 gigs of ram I can use 7200gb and windows is at 400gb used ram already so it shows 7600gb so I can test on all 8 stick and it is stable.I don't know if it is prime95 doing this or my oc is not stable and why would it lock up. Would a unstable oc lock up a computer if it goes past 8gb of ram on the prime 95 test because it can use 7600 gbs of ram so that is working with all 8 sticks.
