Core i7 920 rev D0 stepping 5 :)

drnip,

Your advice please...I have two chips, a 027 and a 026. The 026 needs 1.41 Vcore to do the 231.4x21 validation, the 027 just 1.34. But the 026 runs cooler in all things at the same clock even though it needs more volts. I have an outstanding RMA so I must send one back. Which chip should I keep?

If you can live without the $$$ spent, why don't you just keep both? If not, I would probably keep the lower vcore one. You can always upgrade your cooling for better one later on.
