Quick SLI question

post #1 of 10
Thread Starter 
do the gfx cards have to be made by the same manufacturer, eg xfx, bfg etc etc. i know u have to have the same chipset on both.
post #2 of 10
they don't have to be made by the same manufacturer, they just have to have the same gpu. so a BFG 7800gt can go w/ a XFX7800gt, but a 7800 can't go w/ a 7900.

However, using the latest Release 80 or later graphics drivers, NVIDIA GPUs sold by different manufacturers can be used together in an SLI configuration. For example, a GeForce 7800 GT from vendor ABC can be matched with a GeForce 7800 GT from vendor XYZ.

Nope, you can SLI an evga with a XFX. as long it's the same cards

Lets say I have an XFX 8600GT XXX, would it SLi with a non-factory-overclocked 8600GT model from the same or different manufacturer e.g eVGA??

Yes. However, the core and memory speed of both cards will be set to the lower values of the two.

What if the oc'ed version was in the primary PCI slot??

Or what if the second "slower" card was oc'ed to the clock speeds of the faster card?

it would reset it to whatever clock speed the lower one defaulted to - you would have to use the BIOS or software to overclock it back up.

IMO i'd get an 8800GTS instead
post #10 of 10
it doesnt matter which slot the overclocked card is in, it will automatically go back to the slower card speed. you can then overclock from there.
