Good evening mates,
I oced my rig as in description/signature 3 month ago and two weeks ago, suddenly I got a blue screen and after I wasn't able to run FAH or Prime with the same settings (crashed after some minutes). Also after a cold boot got a lot of blue screens and a lot of programs didn't run properly.
First I thought it was a software/driver issue, so I formatted both my HDDs and made an RAID0 array. Installed the Win7, all drivers and software again. Tried to use the same oc settings but didn't succeed. I tried to reduce the freq but let the Vcore the same. First I set the freq to 4.0, couldn't run Prime for longer as 20min. Then I reduced the freq to 3.8 and set the Vcore to 1.45v, but still the same issue. Prime doesn't run longer than 2 hours without errors. Then I started to oc from beginning/stock. But couldn't find any Vcore setting for stable (Prime) oc. Got always (no matter after what time) errors like rounding error (got x, expected y..). Yesterday I just set the settings on stock (except my memory, it's on XMP profile) and let the ASUS Auto Tuning software to oc my rig (Extreme). So now I have 3.847Ghz @1.4v Vcore. The software increased only fsb. When I run prime, it takes 4-5 hours for first (rounding) error. (I also played some games while prime was on, but I don't think it's a trouble.)
My question now is, are there any oc which "survive" the Prime test without errors? (longer than 4hrs) Because when I oced before, I only waited one hour for for Prime and when I didn't get any errors, I increased the multiplier or decreased the Vcore. When I got an error within the one hour. I increased the Vcore. So at last when I found a stable Vcore & clock (it was 4118Ghz) I just added 2x0.00625v (increase the Vcore by two times) in order to run FAH properly. (Vcore was @1.5125v)
Now I don't know if it's necessary to let the prime run so long in order to know that I won't get blue screens or freezing while FAH.
Any Ideas why that happened?
Best regards,
FA
P.S.: Now I have the following settings: Clock: 3847Mhz (213*18); Vcore: 1.4v; CPU/NB Vcore: 1.3v; rest: Auto
I also run FAH now and we'll see how long the rig can fold.
