As lending it ever tried to equip my PC on. Bought card, reingesteckt and works like clockwork! Dxdiag performed and so could see that the card was immediately recognized by the system, and now I finally have more memory available. Before the old card was removed, so I could see what kind of RAM do I need and I could a DDR2 PC533 CL4.0 with just 1 GB here, see the Amazon fortunately. Clocking the same as my old card, installed the new 1GB in the 1st slot and the old in the 3rd now ordered a second identical card - if already, because already and will upgrade to at least 3GB. Have still 1 free slot and a card I will then replace later against another 1GB and then have 4 GB.
