Ok guys, i decided to push more and see how much further my chip can go. I did two overclock settings, 4.2 ghz with HT on @ 1.29375V and 4.4 ghz with HT on @ 1.36875v. I adjust only Vcore, CPU VTT, and Dram Voltage, all else are on Auto. Please take some look at pictures and tell me maybe i may miss something. Do I need any changes with IOH/ICH I/O or ICH Voltage, or QPI PLL VCore or IOH PLL VCore or IOH VCore?? any tip would be appreciated.

4.2 ghz with HT on:


4.4 ghz with HT on:
