I ran into some very interesting problems trying to find a graphics card
for the PowerEdge 1800 that is compatible with the motherboard and has
for Vista and Windows Server 2003. Unfortunately, the
motherboard has two PCI Express slots that are 8 lane size, but no 16
lane ones as is required by virtually all of the current graphics cards.
Matrox does market a 1 lane board, but there is no Vista driver
There is a PCI-X slot, but there are no known PCI or PCI-X graphics
cards that have Vista drivers
An solution to what appeared to be an impossible problem is to use a
Adex Electronics lane converter. We chose model PEXP16-SX-16/8 which
converts an 8 lane connector to a 16 lane connector. You can now use a
16 lane graphics card. The only catch is that the adapter adds 1.05
inches in height above that of the motherboard connector. There is
plenty of vertical clearance in the PowerEdge 1800 so that the added
height is not a problem.
We chose the Gigabyte GVNX76T256D-RH for the graphics adapter. It uses
the nVidia 7600GT chipset.
