By meomory swapped out you mean to exchange it? And we're talking talking ram? I also wanted to make it a point that my motherboard is ddr yet has 3 ram slots.

does your computer detect the card now? after installing everything? did Jephree's post about the Accelerator help?

maybe you can try unplugging it and reinstalling the whole card and drivers all over again, or try the card on another computer.
