These are in fact a HP version of the ConnectX-3 Pro MCX354A-FCCT VPI Card with FDR10 40/56GbE 2 PORT QSFP. HP Part No. 764284-B2

I ordered several units, they arrived UPS-Next Day in the UK, extremely well packaged in individual anti-static bags, some were in boxes, others in padded bags.

Most were rev. A4 one was rev. A2 and another rev. A3.

They are recognised by Win 10 and the latest Win-OF Driver Package 5_50_53000 allows the port assignment tool to function properly.

Some HP cards flashed with Mellanox firmware do not allow this feature to work properly with the latest Win-OP drivers and port assignment only works using the MFT Tools.

All of the Mellanox MFT Tools work, including MLXUP.

All the cards had the latest HP FW 2.42.5044 firmware.

Here is the Device Query output.

I hope this helps; these cards are much more difficult to find that the standard CX354a non Pro version.

Have fun

I saw that, but he wants 17.99 in shipping for the first card and 9 for each after, which is robbery in my opinion and then it might be cheaper for us non UK people to order something else where a reasonable shipping discount are given.

I tried to do a deal with him and initially there was no postage discount, so 6 cards that I tried to order would cost me (39.99+17.99)*6=347.88 - which is a hell of a lot for 6 cards suddenly.
