problem with it is you the video cards are not the sames size in memory

there is a work around for it

How to Enable Coolbits

Click on your Start Menu in the Windows Task Bar and select Run. When the command box opens, type "regedit" (without the quotes) and press OK. With the registry editor open (shown below), go to HKEY_LOCAL_MACHINE \SOFTWARE \NVIDIA Corporation \Global \NVTweak (expand the menu using the "+" expansion buttons to locate this menu item). Click on "NVTweak" in the menu. Next, right-click on the empty space inside right window and choose "New>DWORD value". Name the value "Coolbits" (without the quotes).



Step 2.Within the Registry Editor, right click on Coolbits and choose Modify. Change the Value data to "18" (without the quotes) and click OK. Exit the Registry Editor.

OK now that I've done that will something show up to enable it... or did i just do it manually and it doesn't have to show? cause i don't see anything ...even after a reboot.

AND THANK YOU!!!

hi fez04, in the nvidia control panel, in the left hand pane do you see "3d settings" if you do, expand the list and there you should see " set SLI configuration" hope that helps you
