Dynaletik Posted April 7, 2005 Share Posted April 7, 2005 Hey out there, is it possible to activate NVIDIA SLI on a Multi-GPU system?I got 2 GeForce 6600GT cards in my pc since 10 minutes, now how can I activate SLI unattended? Is there a regkey? I didn't find anything. (Maybe I'm too stupid.) Link to comment Share on other sites More sharing options...
Bâshrat the Sneaky Posted April 7, 2005 Share Posted April 7, 2005 Isn't it the software that activates it? Link to comment Share on other sites More sharing options...
Dynaletik Posted April 7, 2005 Author Share Posted April 7, 2005 Hm, yes. You have to activate it in the ForceWare driver menu. But there must be a place, where the setting is saved. And this is the place I need. =) Link to comment Share on other sites More sharing options...
Bâshrat the Sneaky Posted April 7, 2005 Share Posted April 7, 2005 I can't find it... I WISH I had SLI Use RegShot or RegSnap to determine the changes in the registry after enabling/disabling it. Link to comment Share on other sites More sharing options...
kenshin Posted April 7, 2005 Share Posted April 7, 2005 I believe I may have found what you're looking for...Under HKLM\SYSTEM\CurrentControlSet\Control\Video, there should be a few keys, two of which representing your two video cards. From there, there should be a "0000" key, which has a "MB_Enable" key. If you set that to "01 00 00 00", it should enable SLI. I'm not sure if you're going to be able to pre-determine the parent key's names, though... Link to comment Share on other sites More sharing options...
Dynaletik Posted April 7, 2005 Author Share Posted April 7, 2005 Seems to be right, for me it is this code:[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{00D4FE2C-2B80-49F1-8362-CF32DEAC70FC}\0000]"MB_Enable"=hex:01,00,00,00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{00D4FE2C-2B80-49F1-8362-CF32DEAC70FC}\0001]"MB_Enable"=hex:01,00,00,00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{E5F8B27F-3185-4315-8FFB-1F8440EAAD1E}\0000]"MB_Enable"=hex:01,00,00,00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{E5F8B27F-3185-4315-8FFB-1F8440EAAD1E}\0001]"MB_Enable"=hex:01,00,00,00It seems to enable SLI, now I hope that it works on a new installation, because I don't know, how Windows generates the {00D4FE2C-2B80-49F1-8362-CF32DEAC70FC}\0000] entries.Thx kenshin Link to comment Share on other sites More sharing options...
