Hi guys, I'm currently using a Core i5 750, Gigabyte P55A-UD3, and 2x2GB G.Skill DDR3 12800. The heatsink used is the Thermalright Ultima 90. IIRC, temperature is hovering in the 28C to 30C range.

Right now speed is at default. Ultimately I would like to do 4ghz on air if possible. However, I know nothing is ever guaranteed so I guess I'll have to raise the clock speed carefully.

IIRC, stock speed is at 2.66ghz. My first goal is to try 3.5ghz. Can someone tell me what settings I should use in the BIOS to increase the chance of hitting 3.5ghz? I would prefer tight timings, but it's not necessary. What voltages should I try using? After overclocking the system, I plan to use Prime95 for stability test and hopefully things will pan out.

Thx for the help in advance!
