well,I have 2 creative v2 cards..the 2 are different models..if mount the two in SLi must I use mm support or can i put drivers with no mismatched suport?

both have 12mb...but differente mems..

and both are ct6670

memory brands dont really matter.as long as both cards follow the same design,they should run as matched.just try some drivers without mismatched support (fastvoodoo2 4.0 for example),and see if the cards are able to run games at 1024*768.if you wont be able to run it,that means your cards are not able to run as matched and you will have to use a driver with mismatched support..
