We achieved our heavily overclocked system setup with a few standard voltage tweaks, bumping the CPU core voltage to 1.5V (1.4V reported here is the variability of the health monitoring software) and setting various chipset voltages for the HyperTransport link, Northbridge and Southbridge to either 1.5 or 1.55V.  


We also bumped our core GPU and Memory interface clocks on the GeForce 8800 GTX cards to 625MHz and 925MHz (1850MHz DDR) respectively.  This was about the highest we could get this pair of cards to cooperate together and it did offer a measurable gain in performance over stock speeds.

 

And of course we had our GeForce 8800 GTX cards running in SLI mode.  On with the testing...
