[TIPS] How to Enable SLI Support for 3DMark11

3DMark11, GTX 460 SLI is ok
3DMark11 and GTX 460 in SLI

Oddly there is still no 3DMark11 profile in latest versions of NVIDIA drivers (like in the very last R266.35). And manual SLI tweaking in NVIDIA Control Panel changes nothing. So how to enable SLI with 3DMark11?

Simply by using a tiny tool developped by NVIDIA and called GeForce 3D Settings Profile Manager. You can download it here: Manage your SLI Profiles with NVIDIA GeForce SLI Profile Tool.

1 – Start Geforce_SLI_Profile_Tool.exe

2 – Export the profiles file

GeForce 3D Settings Profile Manager - Export SLI profile

3 – Add this block in the profiles file:

Profile "3DMark11"
  ShowOn GeForce
  ProfileType Application
  Executable "3dmark11.exe"
  Executable "3dmark11cmd.exe"
  Executable "3dmark11demo.exe"
  Executable "3dmark11workload1.exe"
  Executable "3dmark11workload2.exe"
  Setting ID_0x00a06946 = 0x084000f5
  Setting ID_0x1033cec1 = 0x00000003
  Setting ID_0x1033cec2 = 0x00000002
  Setting ID_0x1033dcd2 = 0x00000004
  Setting ID_0x1033dcd3 = 0x00000004
  Setting ID_0x1095def8 = 0x02c00005
  Setting ID_0x209746c1 = 0x04280001
  Setting ID_0x20ebd7b8 = 0x00000020

SLI now works fine with my pair of MSI N460GT Cyclone as
you can see it on the following picture:
