i have a 3D Fusion 7600GT 256 and a 3D Fusion 7600GS 256. now i know one is gddr2 and one is gddr3 but is it possible to SLI them?
 
Not together I don't think. Pretty sure they gotta be the same kind of card.

What he said. The cards have to have the identical BIOS to run in tandem.

No, identical BIOS's used to be a requirement of yore but the newer drivers only require the same core.


See this from the SLIzone.com SLI FAQ:

Can I mix and match graphics cards?
In order to provide optimal symmetric scaling, SLI technology requires the NVIDIA GPUs to match. For example, a GeForce 7800 GTX must be paired with another GeForce 7800 GTX. Likewise, a GeForce 6600 GT must be paired with another GeForce 6600 GT. However, using the latest Release 80 or later graphics drivers, NVIDIA GPUs sold by different manufacturers can be used together in an SLI configuration. For example, a GeForce 7800 GT from vendor ABC can be matched with a GeForce 7800 GT from vendor XYZ.

So you couldn't do a 7600GS and 7600GT in SLI "offically", but they both actually use the same G73 core. Theoretically with the newest drivers you may be able to do SLI, but both cards would perform at the 7600GS speed. Try it out, you can't fry them.
 
just got back from buying the x2 3800+ and mobo soon as i get everything up and running ill try the SLI and post results
 
Since only one of the cards memory is used, could you flash the GS to a GT. Then use the Real GT as the main card and have the Fake GT (previously a GS) as the secondary. That would negate using the slower DDR2 Ram, and instead use the fast GDDR3 from the GT. I know that GS chips are good for the clock of the GT. Just wondering.
 
cant i just set it to use the GT memory without flashing the gs?

Hynix DDR2 memory has only been reported to overclock reliably to 900Mhz. I had to add on extra cooling to push it even further, so no, flashing the GS as a GT is more than likely to yield all kinds of artifacting errors and more. Again, you'll need to leave it as a GS, push it as high as possible with overclocking and realise that the SLI rendering will operate at the slower RAM speeds on the GT to keep in parity.
 
well my GT died a few days ago so i guess we wont see if it wouldve worked. im on the GS now until next week when i order the x1900XT
