i7 4.8 Ghz Overclock Question - Page 2

post #11 of 14
that vcore should be fine for everyday use... Just keep an eye on temperature when you're doing cpu intensive activities. You don't want it to reach above 75C ideally. 80C will be extremely pushing it, so if it gets to that crank it down.

If you want to use IBT for stress testing you need to install SP1 for Windows 7 and use the newest version of IBT. WIth SP1 this version uses the new AVX instruction set which essentially allows each floating point core to process twice as much at once. You temps will rise significantly and your should go to ~125-130, and it will provide a much better stress test.

Can someone explain how these guys (silkysean page 19) http://hardforum.com/showthread.php?t=1578110&page=19 are getting a 4.8 overclock with a 1.368 vcore and the asus rep from page one suggests a much higher vcore?

Well I tried 5 Ghz, booted fine into windows and even passed the standard Intel Burn test for stability. However, five minutes of prime gave me a BSOD. So, I went back to the 4.8 Ghz overclock and ran prime95 again for fifteen minutes and temps hovered around 79 max. I think this is my limit on this cooler and chip. But I wonder why core one averages temperatures 8-10 degrees celsius lower when under load? Could it be a thermal paste issue?
