I think You need to Disable the internal SLI mode on Your 9800GX2 card. That's what I did for the GTX295. You need to go to Your Nvidia Control Panel and go to 3D settings, Where It says "Set multi-GPU and PhysX configuration", Set 1. to: Disabled and set 2. to: Do not use multi-GPU mode. and then click on [apply] I use XP x64, I don't know what OS You use as It could be Linux or Windows of some sort, But This should apply everywhere I hope.

Like the Joker says it should work as intended when changing the SLI to Single mode. I have the same card which works perfectly.

I however have another problem. This GFX card has approx 2500mb of ram but it only lists about 512mb when I enter my Computer preferences in BOINC.
Already updated the GFX drivers to the newest and reinstalled the BOINC client as well.

I am really baffled about this and have found no solution to this anywhere.

My setup:
GenuineIntel
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz [Intel64 Family 6 Model 15 Stepping 11] (4 processors) - 8GB memory
Microsoft Windows Vista
Business x64 Editon, Service Pack 1, (06.00.6001.00)
