Officially, this is not supported.

Can I mix and match graphics cards with different sizes of memory?
No. For example, an XXXGT 512MB cannot be paired with a XXXGT 1GB in an SLI configuration.

(http://www.slizone.com/page/slizone_faq.html#c19)

 

However, in the older days with older drivers, you can use Coolbits to tweak it to work.

 

See the how-to-enable-Coolbits here:-

http://www.slizone.com/object/slizone_coolbits.html

 

Now, I am not certain this will work anymore with newer drivers.  But you can try.

Even if it works, remember you will only have 512MB per GPU (ie 512MB of the 1GB will not be used).

Yup, it used to be officially you could.... now it is unofficially you can.


I guess NVIDIA's partners got tired of answering all the "Why is my performance worse?" or "Why do I only have 512MB when I should have 1GB+512MB?".
Once again...

Thnx for advice guys, my card ended up being a 1gb so the new card worked well. smile.gif Oh yeh without the SLI bridge as well.
The new 9800gt had no bridge input :/ but apparently with these green version 9800gt's, the PCI-E bus is enough for bandwidth transfer. thumbsupsmiley.png
They also had no power inputs, so no power railings from the PSU lol. EPIC win cards.
