Today we are using a new motherboard from Asus, the P8P67 Deluxe.
We used the performance setting in the bios which automatically configures the components for a reasonable overclock without increasing the voltages too much.
The system overclocked the Core i7 2600k to 4,386mhz and correctly set up the memory at 1.25volts @ 1600mhz (1632mhz in this case).
System validation is available over here.
We weren't expecting to get much from the memory in regards to overclocking, due to the low voltage nature, but we managed to push the configuration to 1700mhz with a bios setting of 1.3v. The timings were maintained at 9-9-9-24. Any higher than this wasn't stable so we decided to limit testing to these settings.
System validation for the overclocked settings is available here.
At this speed, the CPU speed was increased to 4573.76 MHz.
