but i have a e7500 one of the last gen ones at 1333fsb and i think its a Kentsfield.
I specifically avoided buying a quad because my board has problems OC'ing those old quads
and at almost stock voltage i can jack up the CPU 28% and the FSB 41% on air..
i bet your trying to save electricity costs they lol
Definitely trying to save on electricity cost$$$$$$ and still have performance....LOL...I hash about 825~850 kh/sec total.....Also, $0.1323 /Kwhr isn't one of the cheapest rates in the US, but supposedly my area they with half the cost because we live in a valley area....Hopefully next month as PG&E quoted....I'm thinking of slowly buying a few solar panels at a time to make a setup that can power between 5~10 kw/hr with one of those kit off of ebay....
