Will GTX460's with 256bit and 192 bit memory interface SLI

post #1 of 5
Thread Starter 
As the title states. will two GTX 460's sli ok if the core is the same and both are 1G gddr5 memory but one is 256bit memory interface and the other 192?
Reason I ask is I currently have an evga gtx460 with 256bit memory interface and the only gtx460 I can find locally for pick up at a retailer has 192bit memory interface.

I'm wondering if they will sli ok, which I think they will as they are the same core. but how bad would the card with 192bit hurt over all performance? or will it just not work?

any help appreciated.

Yes they will. However the one with the 256BIT interface will down clock/reduce it, to match the 192bit one.

Ok, so coming from evga, my original Evga EE FPB 460 with 256bit memory interface and the evga sc 460 with 192bit interface will not sli.

guess I'm not going to get to sli then. O'well thanks for the reply and preventing me from wasting my time getting that card from frys.


I have to admit I am a little confused by the information on sli. Nvidia's faq on it doesn't mention memory interface at all. only that the cores must be the same and core clock and memory clock must match which is easy to make happen. also that using coolbits you can sli a 1G memory card and a 756MB card.
