Why don;t you read Stevty's posts that confirm that is true. I am repeating his experience, and he has more Intel systems than almost anybody on this forum.
As for the X2 mobo, I have 4 X2's, all running on $80 motherboards. One only runs 2370, thats the dual-sataII board. The others are all 2.5-2.6 And they all get this on stock cooling, which CAN'T be said for the 805. The only way to get an 805 to 4 ghz is watercooling. If you have seen it on air, again they must be lucky. Stevty gets 3.7 on water, and I can only get 3.4-3.5 on air, havn;t had it long enough yet to say for sure, but it won;t post at 3.6
As to your roomate, he must be lucky, I will believe stevty, I think he even works for Intel. I have personally experienced this with him at my house with his hardware.
