I am currently at 3.825Ghz right now. 450mhzx8.5 vcore: 1.325 CPU PLL: 1.65 CPU Term: 1.24 MCH Core: 1.3 DRAM: 2.1 Everytime I try for 4.2GHz, or even just 4GHz, I always have issues. There are so many different voltages instead of just the basic CPU, RAM, FSB, and NB to worry about now... Currently I use Intel Burn test for 100 runs on Maximum, if that passes I run Prime for a bit just to double check. 3.8 Passes both just fine, 4GHz fails after just 2-5tests. I just don't know what to change because I try what I used to do for overclocking, but there are to many variables now:bang:. Any help?
