Core i7 920 rev D0 stepping 5 :)

[darkman]

I have the 3849a822 myself which clocks pretty good (1.31v 4.3ghz prime and linx stable HT off)
It seems the 3845B027 is the best of all... it makes me think that most week 45 cpu's clock good... so if you take the last one, that 3845b258 then I think you have a reasonable chance of a good overclocker.
week 49 isn't too shabby either but I had no choice lol...

sorry for the 3845b258 not in the list are these:

3852a277
3849a824
3851a286
