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

have you dopne a fresh install ?
ive just read a few issues with sli not shoiwng up
a fresh install seems to be the fix
 
Already done yes. And to withdraw Windows completely from the equation, I've also installed Ubuntu, and it doesn't work there either.
 
I think hes done about 3 fresh installs by now heh...

For whatever reason the drivers aren't seeing an SLI certified setup - which pretty much means one of:

Motherboard not working properly or has a "hidden" or manual jumpered SLI switch.
Motherboard not actually SLI capable (with current BIOS) even tho it says it is.
GPUs differ in some way i.e. vendor specific modification (shouldn't be an issue tho as it uses the device ID which matches in the GPUz shot).
CPU is throwing off the authorised hardware detection (possible but seems unlikely).


The hacked SLI drivers can work around some of this but not all.

I once had a duff gtx 280 which worked fine on its own and wouldn't work in sli, same problem as the op where the option would refuse to show up.
 
That's what the rest of us call crap drivers ?

Wow I never knew SLI had so many hardware issues Rroff. The certification process seems kind of useless.

Can you get a list of SLI compatible hardware Rroff ?
 
You can contact Nvidia, with a webnote...

Although finding the links through the maze that they put you through can be a challenge.

Iv contacted them in the past.
 
It's obvious he has a hardware problem/conflict, there are plenty of guys on youtube running the same mobo and 470/480 SLI configurations.

Interesting. I've got an opportunity to test two 9800GTs which have successfully run together in SLI before (different set-up) on Tuesday, so we'll see.

Those people saying about Nvidia and ATI drivers, read the first line of my first post.

On Nvidia's site there's a list of compatible hardware. The Maximus III Gene, my PSU and both GPUs are listed as compatible.

And yes, on latest BIOS now.

I've also tried older (257.21) drivers with and without the driver hack to no avail.

:rolleyes: based on what? 1 issue when for 100000s of people it works fine.
 
What ?

I'll just quote you incase your about to go off on another mad Rolf. But based on what your talking about maybe ?

The SLI hack is mostly for working around chipsets that aren't on the nVidia device ID list if it is a problem with the CPU it won't fix that... would be a bit stupid tho if the authorised hardware check was thrown out by the CPU - as it really only checks device ID pairs against SLI capable GPUs and against the motherboard chipset ID. But knowing nVidia its possible they've done something retarded to stop people strapping AMD chipsets to work and doing an exclusive check against the CPU they expect on a P55 board (i5/i7).

Worth a try though.

I'll contact Nvidia and see if there's any reason why a Xeon shouldn't be accepted in a non-Xeon board.
 
Yeah thats probably worth checking - rather than messing around trying to find out... if you get a reply even :S
