q6600 @ 3ghz for 8800gtx tri sli

[kayawish24]

please tell me that can q6600@3ghz handle 3x 8800 gtx tri sli??????????????????????????
my specs are:-
q6600 overclocked @ 3GHz 1.256V
cpu fan:- cnps9700
mobo:- asus p5n-t deluxe
2 x XFX 8800 gtx overclocked @ 630/1000
4 GB OCZ DDR2 SLI Ram @ 900 2.15V
1 x DVD RW
1 x floppy drive
1 x 320 GB Sata western digital hard disk
corsair TX-850 PSU

Q6600 -- either B3 or G0 stepping (G0 is better) -- will easily do 3.0 Ghz at 1.3 to 1.32V -- which is perfectly safe for those cores.

Your mobo is a 780i board with two PCI-E x-16 2.0 slots and another PCI-E x16 slot like my eVGA 780i board -- probably capable of tri-SLI. This would mostly depend on your power supply -- not your over-clock settings. I'm running two 9600 GT cards in SLI, and I think my NB/SPP voltage is between 1.3 and 1.35V -- haven't had a problem with it for an E8600 over-clocked to 4.25 Ghz. For you, you'd get a maximum over-clock of maybe 3.4 Ghz if you have the G0 stepping. Like I said, 3.0 Ghz is easy.

I think SLI is overly hyped. I wish I'd spent my $300 for the BFG 9600's on a single 260 or 280 gfx card, or better -- a single Radeon/ATI mid- to top-end card. Live and learn, though . . .

By handle 3x8800gtx tri sli you mean the q6600 won't be a bottle neck? They test with a q9650 on the 780i. The higher the clock the better it runs and 3.33 is where they left off. At 3.0 ghz you should be fine but more is better.

I see what he's saying, or what you're saying. CPU had always been a bottleneck for graphics, to be sure.

IMO....I say you have some left in your Q6600...remember it is a Kentsfield....They are 65nm chips that had higher stock vcore.....I think you will be safe to go up to 1.45v...So push it to 3.4-3.6ghz...

It might be able to reach those speeds but keeping it cool there will be another issue. I would aim for 3.2ghz though.

i overclocked my q6600 to 3.4ghz but i did not do any thing in vcore all are in auto in my bios then i ran OCCT for 2 hours on large data set and high piority !!! my cpu temps were maximum 55C even all 4 cores were less then 60C.my idle temps are (wait let me see....)ok!cpu temp is 35C and cores 43 43 38 39C..these all are on overclockes settings to 3.4ghz with vcore set to auto.......but my asus probe says that my vcore is at(wait let me see again)...ok! 1.30V..my mobo tem is 39C....i think i shall run prim95 all night long and still no errors i will keep vcore ,NB , SB volts all on auto just like it is now and cpu overclocked to 3.4Ghz

I'll add a bit more to what's already been said.

TripleSLI GTX 280 on i7 965 - QX9770 - E8400

Big differences. The i7 really smooths out the flow of data through three cards where the QX9770 & E8400 just cannot handle the load as well.

But yeah, pushing your Q6600 as high as possible will help to mitigate this effect.
