9800 GX2 and 9800 GTX in SLI possible? - Page 2

post #11 of 16
I don't think it will work because Nvidia is not as nice as ATI, which allows for things such as this.

^This to a certain extent. The architecture of a 9800 GTX+ and the 9800GX2 are different, so no SLI is not possible. The VRAM size has less to do with though. For example, a 512mb 8800GT will SLI with a 1 GB 8800GT only if cool bits is enabled. It is a tweak you need do in the registry.

Nvidia is not as flexible with multi-GPU setups as ATI's CF. So a GTX 295 which is based off of two GTX 275s will not SLI with another GTX 275. That is just how it goes.

oh and BTW 9800GX2 is 2x 9800GTX with 512MB each and the 65nm G92 core.

9800GTX regular is also the same 512MB and 65nm G92

No, this will not work. nVidia cards don't work the same way as AMD/ATI do(you can do this with ATI cards). But fun idea i guess
