So after messing around with NvidiaInspector and modifying a few INF's... It came to the attention of another user to add/edit a registry key.

First thing's first... Download Nvidia Inspector:

http://download.orbmu2k.de/files/nvidiaInspector.zip

Next, Run it as Administrator and click the Tools Icon as demonstrated and highlighted below:

Next a big window with multiple listings of settings will appear. Within the first 5 entry's you will see two labeled SLi Compatibility bits (DX10) and SLi Compatibility bits for the BASE PROFILE.

Select the values next to SLi Compatibility bits (DX10) and change it to 0x080000F5 then click Apply Settings. The SLi profile for 3DMark11 does not override the main settings when you make changes to it, which is why it needs to be set to the Global Driver Profile. (Make sure 3DMark11 is closed during this time or the setting's won't apply to it until you restart it.)

At this point you should get SLi scaling and performance in 3DMark 11.

Notes: This is no guarantee, but it has worked on two GTX 400 SLi systems so far.
There's been reported flickering with this "fix" or "workaround".

Yeah sorry haha... It's late so my mind's a bit scattered

But it seems to give quite a nice boost if I must say so myself.

Hey, thanks for making the effort to post this.

A couple of addendums and questions:

First off, you need to make sure to open Nvidia Inspector with admin privileges, otherwise the compatibility settings won't be available.

Now here is my first question: Do you need to make the changes for the base profile, or for the 3dmark11 profile?

Irrespective of the used profile, the value 0x08000F5 doesn't work, Inspector will give an error stating inappropriate length and reset. Using 0x080000F5, however, is accepted.

So, if changing the base profile, both SLI compatibility bits and SLI compatibility bits (DX10) are at 0x00000000 per default. Changing either or both to 0x080000F5 does nothing, only one GPU will be used.

If changing the 3dmark11 profile, SLI compatibility bits (DX10) is already set to 0x080000F5 per default (263.09 with modded .inf). SLI compatibilty bits is set to 0x00000000, changing it to 0x080000F5 does nothing, only one GPU will be used.

Are you sure it's not in the SLI section that you made the significant changes?

FYI, I'm running 2 GTX480 in SLI @ 850/1700/2000

Any input would be really appreciated, hate not geting SLI to run with this.

EDIT: I must have made an error before, using the base profile and changing SLI compatibility bits (DX10) to 0x080000F5 does in fact enable the use of both GPUs. However, the picture flashes rapidly. Anyone else experience this?

I did net a considerable increase in points tho, went from 6116 to 9959. Nice!
