Without PAT the result was hardly better than the stock result so I posted the overclocked result for the good old 533 mhz FSB 845E single channel Asus P4B533-E instead, it seemed a more impressive score all things considered.
The Gallatin P4EE will return @4GHz with water sometime in the future. If you think the Prescott is a power hog you have not experienced an overclocked Gallatin! 😉
A small note, my P4C800 is not the -E version but the 2.0 revision of the original one, also have the 1.0 revision somewhere I think. This only matters for overclocking which I think the -E version does better. Im on the lookout for a P4C800-E as I have used the 2.0 to the point where it's impossible to remove the cooler without the CPU tagging along for the ride.
The SI-120 cooler i have is pretty good, and I clocked my Prescott (G1) to 4.25mhz (250fsb), but it was only stable at 1.6v vcore which is the maximum the P4C800-E can provide to a Prescott without voltmod. I got 1.5 more FPS in Doom 3, so I deemed it not worth it in terms of power and heat and scaled back to 240fsb (4.08ghz). I'm pretty sure it can go higher given voltmod and water cooling (or higher RPM fan). I'm probably gonna get a 3.2 EE and try my luck.
One thing to notice regarding the P4C800-E is that there are two revisions there as well. The second revision have MOSFETS designed for Prescotts, which makes it better suited for overclocking (according to info I found in an old forum post, so take it with a grain of salt).
