I have two e8400's..(dont' ask long story) the one I'm currently running is q745a741 batch # it was packed on 1/11/08. I can't get to 4GHZ with it.. but runs great at 3.8 orthos stable for 25 +hours when I shut it down. I have another processor that is unopened that I'm deciding if I want to sell unopened or if I want to install and see if I get the infamous 4.0ghz it is a q746a503 pack date 1/10/08. Is the price drop of an open processor worth the chance of 4 gig?

745A or 746A

First of all, how do you figure out the pack date?
Anyway, I have the same Q745A741 batch code. My chip cannot break 3.96ghz SuperPi 32M stable on WATER. I tried 1.41v and 1.425v and I can't gain a notch. I think the chip hit a wall.
As for your other chip, see how that batch code does before you come to conclusions. Personally, I think it's worth trying another chip as long as you know for sure it will be better (again, look up the batch # to see other ppl's results). You don't really lose much # on used processors... at least if they're still the hot part to get. A used 6 series core2 is a different story, but the cheapest I've seen the wolfdales are $210 ish... and new they are not much more @ all.
So how do you check pack date?
i've tried up to 1.425v on my Q745 and still can't break 3.96ghz on WATER.
Yes, sir... ocforums.com, xtremesystems.org, anandtech forums, extremeoverclocking.com forums... those are the main ones I'm on.
