Hello, thank you for your message. I'm trying to get my i5 750 to run at 4Ghz. I'm using the Asus P7H55 motherboard with Arctic Freezer 13 Pro GTX660, 8GB RAM at 1600MHz, 460W power supply. It's now stable at a base clock of 3,887Ghz with 185Mhz and 21 cores. Temperatures are around 70°C. I've tried increasing the vCore in small steps to 1.35 and 1.325, but the max temps reached 76°C. After about 30 minutes off the bench, the system crashed with a blue screen. I don't know why it couldn't reach 4Ghz. Do you have any suggestions or ideas? (C1Eis disabled)

Each chip varies, which means your chip could miss reaching 4GHz due to manufacturing differences. Don’t overdrive it with high voltage since you recently damaged your i5 by applying too much power.

Adjust bclk to 200, then apply memory multiplier at 8x and boost CPU to 20x. Use IMC with auto mode (enabled via XMP). Set voltage to 1.35v and higher. This chip performs well up to 1.45v with adequate cooling. Previously, I ran an i7-875k at 4.4ghz and 1.352v for about four months before the CPU memory controller failed—pins got damaged.
