8GHZ Club Here we come
After Testing our P5B, P4 631 (ES), and Micron D9GKX overclocks on Stock cooling we decided to move to our next phase of air cooling with a Zalman 9500 Cu and get some higher overclocks. The Zalman was an incredible jump in cooling performance compared to stock but not near enough to handle the voltage of a 5GHZ overclock. We than moved to our watercooling setup, a koolance RP1000, CPU 305 Block, and Black Ice Extreme II. The block had a far greater cooling capacity than we expected. The liquid cooling solution was very valuable to us in our water testing phase and allowed us to determine that with any cooling solution we were experiencing a 40-50C temperature differential between the IHS and Die temp when above 1.45v Vcore. We were able to determine that the removal of the IHS was needed for the Engineering Sample at hand. We ran LN2 on the 631before and after the IHS removal. Testing 1.0v - 1.7v we have determined that the removal of the IHS greatly reduced the Delta T we were experiencing.
We will keep you posted and release more details.
If you would like to help please let us know if you can possibly make the trip to the Coeur d’ Alene Area in the next few weeks. If you have any ideas that could possibly help us in the area of super cooling drop me a line. Even if you just want to be there we could make it a party.
