Asus P5RD1-VM and ATI Radeon X1650 PRO

I wanted to install a DDR-Ram 2 graphics card to a DDR-Ram mainboard
and I asked a pc technician if it´s possible.

In the following you can see the transfer rates:

DDR 333 166 Mhz 2,7GByte/s PC 2700
DDR 400 200 Mhz 3,2GByte/s PC 3200
DDR 533 266 Mhz 4,2GByte/s PC 4200


Taking everything into consideration he said it´s practicable, but the card
wont work on full-speed(-used to capacity), because of the above mentioned transfer rates.
