Simple question, can you run a 7900GTX and a 7900GTO in SLI? I ask because I got a GTX on e-bay (got lucky) and am looking at buying a GTO (cheaper) when they get restocked, unless someone knows who has them in stock.
 
Nope... it wont work (I'm 99.99% sure of that). the GTX and GTO have different bios's... so they wouldnt work together
 
Haha, I got a 7800GTX on someone else's error too...well kinda, some people may knwo what Im talking about.

Anyways, no it wont work.
 
Thanks for the info, just another stupid question then, if I buy another 7900GTX does it have to be the same brand? I got an XFX and was wondering if I have to get another XFX to run SLI, or can I get an MSI or whatever? Again, thanks for all your help, i've looked around but this info eludes me.
 
yup yup it's actually really easy to do that. nvidia's sli is well integrated into mobo's, so problems rarely occur if you did everything right

Yea you can use any name brand togather as long as its the same GPU and ram amount
 
what about flashing the 7900GTO BIOS to a 7900GTX? i never thought of it till just now... same exact specs and all of the same hardware on board, just lower clocks, right?
 
Soooo try what Ku-Sama said and flash the bios. Although that should be checked and double checked to see if it works. Don't see why it shouldn't, with those two cards.

I have a Asus 7800GTX and a MSI 7800GTX in SLI :) question answered? =)

I've been told lately (dont know who it was, so tell me if you want the credit for it :P ) that the GTO has a different type of RAM as the GTX.
so I'm not so sure if flashing the bios would work
 
same 256-bit RAM and such... besides, if they used a different brand memory and that made it incompatible then you couldent use different brand videocards to begin with...

I say buy a 7900GTO, flash it, if it goes to a 7900GTX then keep it and try SLI, if that works then great, tell us so i'll try to flash mine...

if flashing it works, but no SLI, then reflash it, send it back for a refund, if not flashable, reflash it back to its original and send it back

Archangel is correct, the GTO uses Samsung memory while the GTX uses Infineon. This isn't a problem - the problem is that the GTO has a lower Vmem than the GTX. This isn't set in the cards BIOS, but rather hardwired, and adjusting it would require volt modding (although as volt mods go, this one is rather simple).

Having said that, most (but not all) GTOs will overclock to GTX speed anyway. Provided yours will do this (check it first), you should be able to crossflash to a GTX BIOS, and run the cards in SLI.

If that fails, you may be able to crossflash the GTX to a GTO, and run the two cards in SLI with the reduced memory speed. I haven't looked into any specific complications with this, but in principle it should work.
