I have thinking a while and can't get to a conclusion
I have two graphics cards: A GTS 250 I use for my main GPU and a 8800GT I use for Physx
I've beem thinking about this SLI tehnology and theoretically I think I cant SLI them but Im not quite sure
Becouse both of them has the processor of (G92, 65 nm, Die size 330mm2 Revision A2 and 754 million transistors )
Differs only the memory size and the clocks and some thing called device id.
So what do you think ?

Nvidia would block your attempt if you try it, theoretically they can SLI because as you said both use the same core. You're wron on the 65nm point though, a 250 is an improved version of the 9800, which is itself a 8800 repackaged. The 250 comes with the die shrink that wasn't in the 8800 as well as supporting newer features such as 3d vision and the like.

Can something do go wrong if I try to connect them ?

Other than it won't work not really, you can try but I have no idea if this would work or not.

The GTS 250 should actually have a 55nm core, not a 65nm core, since it's not an actual variation of the 8800/9800GT, but a newer version of the 9800GTX+.

I do not believe you'll be able to SLI them. And while I doubt it would damage them to try, I do not know for certain that it won't damage them.

You mentioned they have different memory capacities. It's probably a safe bet that the 8800GT is 512MB, and the GTS 250 is 1GB. Half (512MB) of the memory on the GTS 250 will be unavailable in SLI if it is actually successful.

Well I check the cores on both card with GPU-Z and yes the 8800GT is 512 and the GTS 250. I think I will give it a try, but I was curios if there is any patch or tweak or something to help me out with this

Unfortunately you can't SLI them,in 90% of times the cards have to be exactly the same.
You can SLI a GTS 250 with another GTS 250 or with a 9800GTX+(As long as they have the same memory)
