We are working on a comprehensive overclocking guide for the i7/X58 platform to fully explain each BIOS setting as well as providing an easy to follow set of instructions to get the most out of this new platform. In the meantime, we are showing our initial overclocking results with air-cooling and the i920. To be blunt, overclocking the i920 on air to 4GHz is fairly simple: raise Bclk to 191, enable turbo and HT modes, set VCore to 1.4125V, VTT to 1.30V, VDimm to 1.67V, and set your 6GB kit to 9-9-9-24 as a good base start. After that, it is merely a matter of fine tuning the voltages a little and adjusting memory timings for improved performance and/or stability. Of course, all of this depends on the quality of your memory, cooling, and CPU. In our case, even with very good air-cooling, we found the practical limit for VCore to be around 1.425V without incurring throttling under load temperatures. Based on this setting, we arrived at our 21x191 setting. We will take a further look at overclocking on these boards and others with a CoolIT Systems Freezone Elite shortly.
