can the 9800GTX be SLI'ed with an 8800GT?

post #1 of 15
Thread Starter 
I know ATI cards can go backwards, and I remember reading that some Nvidia cards can do this as well. Can the 9800GTx do it? Or will I be better off hunting for an 8800GT?

No, they cannot be SLIed together.

I'm 99% sure you can't, you would need another 8800GT for it to work, and it's best to take an identical card to the one you already have (so another BFG 8800GT OC would work best )

No only the same GPU can be SLI'ed. (ex. 8800GT with 8800GT, GTX280 with GTX280)

Has anyone else noticed that there has been a ton of these types of threads lately?

No. Have to be the same. Only way you can get around this is to flash another card with the bios of another model, if it compatible. Manufacturer can be different, but only the 9800GT and 8800GT series i believe can be done like this.
You would need another 9800GTX.

actually you can SLI a 9800GT with a 8800GT. just takes a bios tweak and its easy.

It has to be the same. if you wanted to sli with a 9800gtx, you have to have another 9800gtx or 9800gtx+. If the sli connectors don't align due to them being different model numbers, you will need a flexible sli bridge.

So wait, what nvidia card was backwards compatible? Or was that only ATI cards?

None of them are. SLI requires you have a 2 cards with the same amount of memory on each one.

9800 GT might be an exception if you change the BIOS for the 8800 GT to a 9800 GT (its essentially the same card).

You can use the second card in PhysX if you want however.

There is a big sticky labeled "answers to SLI related questions" at the top of this forum.
