Is there a problem with the second GPU on this card? Im worried that it says disabled. Could this just be bc its in 2d mode, like a low power mode or bc of it being 32 bit xp?

Just want to know if I should be rma'ing this card.

all drivers are up to date too

Thanks

Your problem is 32-bit windows. You need 64-bit windows. 32-bit windows only lets you use 4 gigs of ram TOTAL (normal ram AND video ram).

So you have 4 gigs of ram and 2 gigs of video ram = 6 gigs total BUT windows can only see//use 4 gigs out of that 6.

No,he is talking about its card and u answered about RAM :) 

To OP,download GPU-Z and run 2 copy of it and click on sensors tab on top and go to a game and play a game for about 5-10 mins with GPU-Z opened in background,then when u are in game press ALT+TAB to come to window and see if the clocks are the same or not.
HD 4870X2 has a power saving option which downcloks the GPU in 2d mode.

Thanks for the tip.......

I did that, I think i was playing mercenaries2, the one core was loaded and the other was not. In the end I reformated with vista x64 sp1. Now when i go into ati overdrive it says both cores are linked ;) 
prob solved
