I just picked up 3 Q6600's from Fry's by pricematching the Microcenter $199 price. All G0 SLACR's.

The one I targeted for my desktop (the other two will go into servers as upgrades) is a L739B890, and has a VID of 1.2250v. I can overclock it to 3.420Ghz (380x9 FSB) with 1.35v with no issues.

One weird thing though is that according to core temp (0.96.1), core #1 and 2 always run hotter than cores 3 and 4, usually by 3-4 degrees at idle, but 6-7 degrees under load. I am using a zalman CNPS9700, and the motherboard is an asus commando. Is this normal, or is something screwed with my thermal paste or something else?

I have two other Q6600's, batch numbers L745B154 and L745A675. Does anyone else out there have those? Do you think I would do better with them than with the L739B890?

One of them will not be OC'd, but the other will go into a server that does a lot of transcoding, so I plan to overclock it as well, but the best overclocker I want in my desktop. ;-)

Thanks!
