Are you after more speed or more stability?
You're clocked to 4.8ghz in your sig, can you run Prime95s blend test, for say an hour at what your memory is stock clocked to?
If the answer is No.
Leave the timings as they are, drop the memory speed to 1333 and the DDR3 voltage to 1.50v, and try again.
Yes I can run 4.8Ghz for 4 hours on prime with the ram operating at 1600Mhz. I use the 4 hours prime95 test now because of your recommendations. Thank you for that. I would say that thanx to you and Leaps From Shadows I now have my machine purring along.
The RAM OC was just about seeing if I could get a bit more out of it. But I have looked at LFS answer above, and I remember seeing you post on another thread.."Keep the stock timings".. so, considering all the goodness you already brought into my life on this matter; I am going to stick to that advice.
I was interested in learning about the concept of "tightening RAM timings".. but I guess that in the circumstances, I can get an older cheaper com to play around with all of that stuff.
