GTX260 Tri SLI - anyone try?

Small update. I did some individual card testing to see what each one could do. The common denominator is 750 on the core, about 1550 on the shader and 1225 for the memory clock. I can also hit 4.4 GHz on the CPU. Now, can I do all that at once? Three cards at those clocks and the CPU at 4.4? Unfortunately, no, I think I ran into a power issue. I have a new PSU coming that will supply 1200 Watts and while I was at it, I picked up a QX9650. I have seen plenty of those reach 4.0 GHz on good air or watercooling which looks promising for the phase.

I will post up some screenies in the meantime with Crysis while I wait for the updates to see how far I can push this setup. The PSU is key (here Friday) and the CPU is the optional item (here next week)

My QX9650 will bench between 4550 and 4500 on water. You should hit 4800 pretty easily I would imagine.

You should have your phase tuned for a quad. You'd probably be able to get 5GHz if you did.

PS: Want to send me some money so I can buy a 4870 and a 4870 X2 so we can compare?

It is tuned for 250 Watts, already. My CPU runs at -18C at 1.45 V.

Well, now that I picked up the QX9650 and new 1200 Watt PSU, my wallet is a little light

lol. It was worth a shot.

And I hadn't realized you already had your phase tuned. You should have it tuned for 300W then.

I think stock it was 200 Watts, so not enough to handle a quad with some decent OC into it. I have had it as high as 1.6V for some bench runs. I figure that the 9650 will OC with the same or less volts, so it should be a good combo.

Yeah. I don't have the best clocker, so mine takes 1.4V (real) on h2o for 4GHz, 24/7 stable. I've seen better chips doing 4.2GHz on 1.4V, just to give you an idea.

Btw, the chip's built in temp sensor is most likely going to be wrong. Don't bother with it.
