SLI option not showing up. I thought Nvidia drivers 'just worked'

£139.99 brand new retail. It's basically an i5 750 with hyperthreading. That's why. Anyway, it's like socket 775 Xeons which were basically the same as their desktop counterparts, and work perfectly in desktop-supported motherboards. This is no exception.
DSR is a consideration. Though I have taken them up on the Mafia II and Just Cause 2 offer...
I shall try with 197. If GTX470s are supported.
TBH I think it's your CPU making the mobo throw a wobbly where SLI is concerned, your CPU will not be supported in any bios released by Asus for that mobo, if that has a direct impact on enabling SLI, who knows, stick a supported CPU in and see.
If both cards work perfectly fine on their own, I can't see how they are the problem.

I cant see a Xeon being a problem. Its just another 45nm chip.
That I cannot say. I'll have to have a look around again. I seem to remember seeing a few SLI set-ups bobbing around.
As my previous link showed though, it's not limited to CPU problems. A guy had 3 GTX480s on an Evga mobo with a 980X (all supported) and has the exact same problem as me.

BIOS-basic input/output system, xeon not supported in any Asus bios on OP's mobo, draw your own conclusions. First thing I would query if I was Asus tech support.

Thanks for letting me know what Bios stands for, in 15 years of using computers i never knew that Raven
I guess its possible but imo the CPU would be one of the last components i would suspect that is causing SLI not to work.
Will be interesting to find out what is causing the OP problems for SLI not working
nVidia's system for checking if SLI is permitted on the hardware is a bit... "special"... i.e. possible scenario to "prevent" people strapping AMD chipsets to masquerade as intel ones to get SLI working they'd check if it was an i5/i7 CPU and if not shut out SLI support... as the xeon isn't officially supported it might not have been taken into consideration... this is all assumption tho.

98% of the time cpu updates for bios's involve, naming them correctly, and thats it.
Very rarely a new type of cpu needs a new bios, I've run a dozen mobo's with "unidentified" cpu's because the bios hasn't caught up to the lastest cpu release.
A Xeon is identical in every way in architecture, if it didn't work it wouldn't boot, if it boots, it works, its really that simply with CPU's, if he can get to windows the CPU is not the issue. Undervolting the cpu because it doesn't know the default voltage is potentially an issue but it should read it from the cpu anyway.
The xeon is a renamed chip, nothing more or less.
If you take your chip out, write xeon on it and put it back in, it still works even though its got a different name on it.
SLI also isn't supported down to cpu, its down to chipset, it will detect a chipset not the CPU.
As said, other people have the same problem AND there are boards out their with the same mobo and same chip who have SLI working.

Solution listed at the bottom of that thread, by a guy who can't get any other method is to go all the way back to 191.07 drivers.

Thats something like 40 threads on the first page going back what 3-4 days.

and that is the thread with 15k views, that goes back over a year, for a problem Nvidia have been "looking into" for over a year and still haven't fixed for many people.
Nvidia drivers just work
Its clear as day its not the cpu, loads of people have the same problem and fairly standard setups, buying xeon's to use in normal mobo's has been standard for years and the fact it works means theres no major compatibility issues.
