Naturally I assumed that the 1 hour benching session caused it to degrade. Well, it has been close to 2 months since I even touched Prime or my BIOS, and the Vcore has been at a constant 1.35V with load temps in the high 40s, low 50s. I ran Prime today and it is not stable at 4200MHz even at 1.37V. What is up with that?? I am really confused, why does my stability continue to decline? No variables changed in the last 2 months and an Overclock which was Prime stable for over 16hours now fails in between 10-20minutes!!
You prolly need to go with an extra 0.05mv over your initial 1.33, which puts
your new vcore requirements at 1.38. I think it will make it stable at that vcore, and it should not decline any further, based off my findings.
