Not cutting edge but a nice upgrade Q6600 - Q9550

Even with water cooling my Q6600 was running low 60's at 3.4 and would quite often fail the prime test after a while.

Bought a 2nd hand 9550 of the bay this week and straight from the get-go it's almost at 3.8 and running rock solid and and nice and cool. SSE4.1 helps with some of the multimedia stuff as well.

6 hours of priming..

Mobo is a fairly old gigabyte GA-P35-DS3R (rev. 1.0). I've got 8GB of 1066 DDR2 in it which probably doesn't help my clocking attempts.

3.8 seems to be the limit of this chip without getting silly with the v-core. Currently sitting at 1.38v. How much juice can these things handle safely??

1.4 vcore/vtt is the max you want to push through them. Probably about the limit of a P35 DS3R. On a P45 you'd probably get 4gig on same vcore.
 
Thats pretty good going on a q9550 on a p35. I had a nice 1.200 vid q9550 EO stepping chip, done 3.8ghz on 1.216 vcore, i.26 vtt and 1.26 nb voltage, albeit that was with an asus p5q deluxe p45 board, ran really cool as well, 57c was the highest temp i seen running prime95 under a lapped TRUE black with 1200 rpm fans. Only sold it to fund my i7 rig, kinda wished id kept that combo and saved a bit more.
