Negative VRAM issues/Asus Rampage Gene/ATI 4890

[macguy4u]

Hey All

Im new to the board --I finally got my system up and running and its great EXCEPT a little problem.

Anyone know how to correct the negative VRAM issue with ATI cards.
I cant install Final Cut Pro because its seeing a neg VRAM.

I went and bought a Nvidia GTX 260 card and I cant even get that card to send out a signal to even see my bios-Might be a problem with the card. (this was just for testing purposes)

I would like to get my Sapphire ATI 4890 card issue resolved if possible.

Thanks

Matt
