    I ordered 2 of these cards based on the experiences others posted in this thread. I offered $19/ea, they countered @ $20/ea. I bought 2, with $12 shipping. I got the cards in the mail today, and inside the package, there was 3 cards. One had the bracket on it, and 2 others had brackets, but no screws (all short brackets). I emailed the seller, to let them know they sent me 3 cards total. They emailed me back saying they didn't have any more cards with the brackets already attached, so they sent out 3 cards to make up for the missing screws.

    So essentially, I got 3 of these cards for $52. I need to get them in and test the ports to see if I am lucky enough to have working cards like others have been.

    MCX354A brackets should work with the 314A's... I've got several of these coming so should be able to confirm in a week or two...

    Alternatively you can call Mellanox. They've been good about brackets in the past...

    Where are you located? And does anyone have a link to a cheap cable for these cards? Will attach directly.

    Apparently I can't insert images. Link:

    Is yours marked as 314a or 354a on the back?
    I just gone mine and are all maked ConnectX-3 EN 40GB 314a. I.e no mention about Pro.

    And your testing with iperf3, i assume it's 10G you were testing since you use SFP+?

    I know your quote wasn't directed to me, but I ended up with 5 of these cards from the same seller. All of them are CX314A-BCCT. And all 5 say "Connect-x3 Pro" on the sticker on the back. They have different dates and different rev's though. One even says "Engineering Sample". I have only had a chance to install one, and I only got as far as downloading drivers and getting it to recognize in device manager. Hope to try and transfer files before the weekend.

    The fifth one is currently still in the machine, but it came up as 'Pro' in device manager.

    All of mine said 314a pro. [​IMG]

    I tested with my lb6m and iperf3.
    At this point they are in “homeprod” and have been running without issue.

    My 5 arrived today. They are all Pro cards. Just waiting on FH brackets to arrive so I can test. Quick visual inspection shows no obvious defects. All ports take QSFP+ cables and unlatch easily. Once I have brackets I'll see about FW upgrades on these and validate they work. Expecting them too as others reported...

    I tried all 5 of mine, and either I'm doing something wrong, or they're all duds. I'm working with windows 10 and I can't get the ports to recognize. They all say they're disconnected. Installed the driver's, updated firmware, no dice.

    Mine are locked and all show up as ethernet.

    Under HCA port type configuration:

    HW defaults is selected and the options are greyed out.

    If I uncheck HW defaults, everything stays greyed out, and Ethernet is selected.
