HoLoDreaM Posted March 4, 2009 Posted March 4, 2009 (edited) Ok I can't figure this out. I've tried uninstalling and reinstalling drivers multiple times, even running drivercleaner pro, and using stock and modified XG drivers. I have the SLI bridge installed, the mobo switches moved to enable SLI and got the power cables plugged in. I had a BFG 8800GT 512mb, and got a 9800GT 512mb. I flashed my 8800GT to a 9800GT BIOS. The system shows I have 2 9800GT's installed, but no SLI. Nhancer says SLI Disabled along with GPU-Z. The old 8800GT is in the primary slot, and the new 9800GT is in the secondary slot. What do I have to do to get SLI enabled around here? I've searched google, OCC, and other sites. Can't find a fix. See my specs in sig.

ARandomOWL Posted March 4, 2009 Posted March 4, 2009 Don't you have to enable it in the nvidia control panel first? Share this post Link to post Share on other sites More sharing options...
STRAITPEAK Posted March 4, 2009 Posted March 4, 2009 (edited) Don't you have to enable it in the nvidia control panel first? Yes you need to enable it in your Nvidia controle panel. You might need to update that as well and try installing there performance groupe. Edited March 4, 2009 by STRAITPEAK Share this post Link to post Share on other sites More sharing options...
HoLoDreaM Posted March 4, 2009 Posted March 4, 2009 (edited) It is NOWHERE to be found in the Nvidia control panel. Oh and nHancer says "SLI Setup Detected" and below it it says "SLI Disabled" in red. Edited March 4, 2009 by HoLoDreaM Share this post Link to post Share on other sites More sharing options...

Boinker Posted March 5, 2009 Posted March 5, 2009 (edited) hey Holodream. I was attempting to sli a 7950gt and a 9800gt a while back and the BFG tech rep, that i spoke to for the same issue, told me that you cannot sli two unalike cards. The reason that I say that is the info in my head is scetchy and may be incorrect. And i cannot remember why for the life of me. good luck B:) Edited March 5, 2009 by boinker Share this post Link to post Share on other sites More sharing options...
HoLoDreaM Posted March 5, 2009 Posted March 5, 2009 Im using the latest drivers and have tried many different versions. I am very aware you cannot SLI two unalike cards. The thing is. early editiion 9800GTs (like mine) have the identical core as an 8800gt, just a different bios. I just split my partition and installed a Vista Ultimate 64bit fresh copy and isntalled the latest drivers, and i still diont have an SLI option, so it cant be a windows issues. I'm gonna try and give the real 9800gt the same bios as the my fake 9800gt Share this post Link to post Share on other sites More sharing options...
