With manual adjustments, we moved from 453MHz on the FSB to 468MHz, bulldozing down the 456MHz effective FSB "wall" of the Core 2 Extreme we had on hand. All these were done with memory running at CL6, well over 1.7GHz effective data rate.

To accomodate cooling limitations, we dropped the FSB a little to acheive a stable CPU clock.

3DMark's multithreaded CPU benchmark benefitted from the clock increase. All the above results were run on Vista x86 without SMBus drivers installed. As much as the VRM kept our CPU stable, we could not help but notice the loud whining of the inductors under high current stress.
