You used to be able to force them to work together using Coolbits... I'm not sure though if you can still do this... I think they removed that option in newer drivers.
"When purchasing a second graphics card, you should try to match the memory size so that you are ensured full value and performance from your purchase. However, while it is not recommended, NVIDIA does offer the flexibility to run graphics cards with different sized memory by using CoolBits. Using CoolBits (value set to 18), you can force both of the cards to use the lower of the two memory sizes and operate them together in SLI mode. When dissimilar memory sizes are enabled to work together using CoolBits, the effective memory size for each card becomes the smaller of the memory sizes. Instructions to enable this feature can be found
I'm pretty sure you would have to use old drivers to get it to work... Some people claim they can get it to work but others say it doesn't work worth a $hit...
