sli with 560 ti 1gb and 2gb possible?

post #1 of 7
Thread Starter 
I have a msi gtx 560 ti 1gb version, im wondering if when buying my second card for sli if using the 2gb is going to be worth it?

I've never had a or researched sli much but I think I understand a faster card will have to down clock to the lower card speeds, is this the same with memorY?

If you SLI 1 GB cards you only have 1 GB usable, it's mirrored, not combined.

If you're talking about 1 1GB card and getting another 2 GB card, it would be limited to 1 but still work as long as they're both 560 Ti's. The clock speeds would also be limited to the slowest card as well.

Memory type don't matter but GPU type does. As long as they are GTX 560 Tis then your good.

Memory will be based on the lowest, so it would only have 1Gb usable, sort of a waste

Yup just like physical system memory.

It will default to the lower value, they are not additive as well. So you will have 1gb of ram.

I think its a waste too imo. Just get a 1GB card if you have a 1GB card. No sense in getting a 2GB card if you can't use its full memory capacity.
