Hi folks,

I currently have a 9800 GX2 "BLACK EDITION" and i would like a second GX2 to go with it, but i'm having trouble finding another Black Edition as they are uber rare limited edition..

So.. i was wondering if it would be ok to get a standard GX2 and overclock it to Black Edition spec (700mhz core + 1050mhz memory + 1700mhz shader). If so, what is a good program for overclocking a GPU? I have only overclocked CPU and RAM.

Also, would they need to be the same brand (XFX) or is it ok to mix brands in SLi. And i was also thinking of upgrading to 8GB RAM to make it even more beastly.

Cheers.

MSI Afterburner and EVGA precision are great tools. MSI afterburner even lets you set your own fan speed profiles.

As long as the card model is the same, 9800GX2 in your case, It will work. Black Edition does not matter.

ok, thanks mate.

is 720w enough to run two GX2?

Could you possibly flash the one card to the black edition bios ?

720w is pushing it to the limit with those cards, even though you have a very quality power supply. Keep in mind that is 4 g92 cores operating, they are going to use a ton of power.

9800GX2's in SLI draw < 350 watts max load. Your 720 Enermax should technically be able to handle it assuming you have enough amps on the rails.

Back in Jan 2009, I had Q9450 @ 3.6, striker II extreme 8GB DDR3, 2 x GX2s. The gaming performance was horrible due because of lag/stuttering. I had upgraded to 2 x 260s and it was much smoother, and higher frames.
I recommend not getting the second GX2 based on my experience.

BTW, I used PCPowerCooling 860w, 4-5 drives, 3 DVDRW (used frequently thats why i listed it), lots of fans/high output fans.

Not a good upgrade. If you want more performance sell the GX2 and get a GTX470 or a GTX295

what about folding?? im getting a 9800gx2 just for that.. being that 9800gx2 gets almost as many points as gtx285.. and 9800 cost like 120$ used.

Quad SLI and 9800GX2's pulled 22K in vantage a few months ago but the DDR2 memory kinda made BC2 choppy
