Quadro FX1500 - SLI or no SLI?

Hi,
I've recently bought a new computer with a Mobo featuring Nvidia SLI nForce
chipset. With it, i bought a Quadro FX1500 GC which according to Nvidia's
web site DOES NOT support SLI technology.
But here comes the intriguing part:
On Control panel>Display>Advanved>Quadro FX1500 there is an option for SLI
which is currently left blank because there is only one GC installed on the
mobo (as it says). now i'm confused! does this statment comes from my GC
driver which is telling me that if i'll add another Quadro FX1500 GC then i
will have the option to turn it on and actually use it? Or, does this
statment comes from the Mobo driver, which means that if i'll get 2 GC's who
actually support SLI (according to Nvidia's web site) and put them on that
mobo, then then and only then, my system will support SLI?

Please help me to understand,

Thanks,
Gil

 

First of all i want to apologize that i didnt post the original massege as
OT.

O.K. I've checked further and it does NOT support SLI.
How did i reached this genius conclusion, you might ask? well, I opened the
computer and took a look on the GC, and there where the SLI connector is,
there is a lable attached which says "no SLI supported". :-( that is called
"whishful thinking".
But, because I didnt took in account SLI when i bought this computer, i can
say i'm not very dissapointed.

Happy new year everyone!
