We bought a refurb workstation with a P2000 in it (Dell 3620, we have a few already), listed as having 5Gb of ram.

Performance seems a bit lacking, and see that the system is reporting it as only 1Gb RAM.

As far as I'm aware there is no such thing as a 1Gb P2000....

Any idea how this can be?

Tried different drivers (which all loaded), it still says the same.

If its a faulty card hopefully I can get it replaced.
