Some time ago I upgraded my *cough* Dell 730x motherboard to a refurbished Gigabyte X58A-UD3R so I could have the option to OC CPU & RAM.

When I started crunching with it I noticed that my HD 5830 appeared Twice in BOINC Manager. I thought it was some kind of bug in BM and since I was crunching Moo, I just ignored it. However, today I started crunching MW & Collatz and both projects are running two instances. The wu's are completing without errors.

Note that in Windows Hardware manager only one 5830 is listed. Same with CCC.

Any ideas??
