Core i7 Overclocking by Batch #

[Sam_oslo]

Next stop 4.2Ghz at 1.288v. i7 920 3845B260 seems to be one of those higher vcore low temp cpus - it runs around 0.05v higher vcore than my Xeon 3845 cpus but runs around 3-5C cooler than my W3520 3845A935 and around 10-13C cooler than my W3540 3845B010 at same clock speeds even with higher vcore requirements!

You got a good 45-lineup there
Up to 13'C difference at the same speed, sounds like a shame for that b-batch w3540. This is an important discovery, and maybe we need a new Vcore/temp ratio for judging the i7-batches.
