Upgrade to QX9650, Q9550, or keep E7500 (3.6 O/C)

You're not hitting 4.4ghz-4.5ghz on air unless you have a golden chip. Realistically, under water, you are looking at 4-4.2ghz. a Q9550 will be just fine for your needs, or if a Q9650 if you want to spend the cash. You want to get an E0 revision. QX9650s only come in C0/C1. If you have a good board, you should be able to do 500x8 no problem. VTT is safe on these yorkfields up to 1.4v, but in most cases, you won't need to go over 1.35. Out of the four Yorkfields I've had ( Two QX9770s, a QX9650, and a Q9550), all but the QX9650 hit 4ghz without trying, and that was because of a terrible board with the QX9650.


If you have money to blow, spend it on an I5 650, P55-UD3, and a set of DDR3 and enjoy 4.5ghz on air or higher.

Also, sorry to break it to ya, but Balmang, 1.32v for 4ghz on a Yorkfield is not low by any means. That's mediocre at best, good chips do ~1.25 or a bit lower for 4ghz. Not to say you have a bad chip - who knows, maybe it scales very well with voltage.
