gtx 460 and gtx 460 se SLI compatiable? Get it to work?

[Esk]

I have 2 totally different 260's that SLI'd fine.
One custom and one non custom PCB, both with different clocks (until I Oc'd them) and both running different Firmware.
A 260 is a 260, an as far as I understand it nothing has changed so it should work for 460's.

Only reasons i could see it not showing are lack of power to run both (you need the right 12v rails as well)
Mobo cant do SLI (rare now but) or the mobo is crossfire (I've actually seen people do this is why i say)

That will teach me to get a brew and Google before I answer when its not about OC'ing lol

90% sure the GPU core is different, so no it cant SLI. it shouldn't be called a 460 fs.
Return it and get a GPU with the same spec in the core (so most others).

If you link the full make/model of both cards I'll look make sure for you.
