This card should be the latest that Socket makes, I just bought it, and the "Rev" version is "G". The card is software upgradable, but my understanding is that the latest firmware is version G.

By default my card shows: Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 (Seems to be missing only HV2, HV3) I am able to get a connection if I only turn on DH5, but here at work I'm unable to get good phone service for testing. When I go home I'll check it where I get five bars of service to see if forcing the largest packet size will give me higher speed... Jay
