My 2.8E prescott, on an Asus P4P800 ran at 3.5Ghz, with a thermalright SP-94, and PC4000@1:1

My3.2Ghz ES prescott only got to 3.6ghz, using a thermalright XP-120 on my Abit AS8, currently running at 3.46Ghz in my PVR computer.

My 3.4Ghz LGA775 prescott is stable at 3.99Ghz on my Abit AS8, using the Thermaltake bigwater 12cm.

Meanwhile my almost 3 year old 3.06Ghz is running at 3.45Ghz on a Gigabyte 8IK1100 with the XP-120, and keeps up with, or outperforms the prescotts until they get up to around 3.9ghz, in most applications, athough the Prescotts do win by a nice margin in the applications they do better in, such as SuperPI. The northwood seems to do better in audio encoding, file compression/decompression, and in rendering. The prescott seems to do better with video encoding and multitasking.

Did you have to make any modifications to the AS8 board to get the xp-120 to fit? I have some concerns over the chipset cooler that I want to sort before I go ahead and buy one. I'm pretty sure it wil fit in my Antec Sonata case /crossing all crossable appendages

I did actulay have to turn the northbridge chipset cooler around as the fan was in the way of the XP-120.

My 640 did about mid 4.1 while my 660 does high 4.3 to low 4.4

I was going to ask how you far you turned it, but looking at the board you can only go 180 dergrees. It must still have been quite a tight fit getting it onto the board though. I can always send it back if it doesn't fit on the board, I guess.

I managed to get the xp-120 onto the board after some creativity with a pair of pliers and the nb cooler. Temps dropped an incredible amount. Managed to get it up to 4.165 with a super pi of 32 seconds, but it wasn't all that stable. I've got it running @4 24-7 now though, very stable. Big grin on my face when I broke 4GHz though, such a child

Good to hear. These newer prescott cores are quite a bit better than people give them credit for.
