Mellanox ConnectX-3 Pro Firmware questions

Hi!

 

I purchased 2 Mellanox MCX314A-BCCT cards on Ebay for my Unraid server and my Windows 11 pc.

I managed to flash 1 to the latest firmware using the Mellanox app from the Unraid appstore, which is 2.42.5000 according to the Nvidia website, but when I tried to flash the other one I get the following error :

 

-E- Burning FS2 image failed: Device/Image mismatch: FW image file cannot be programmed to device ConnectX-3 A1, it is intended for: ConnectX-3Pro only.

 

But when I look at the info it says :

 

02:00.0 Ethernet controller: Mellanox Technologies MT27520 Family [ConnectX-3 Pro]

 

So I'm a bit confused, because it IS a ConnectX-3Pro .

 

Is this a fake card?

 

I also tried the -allow_psid_change burn, but it still won't work.

 

Thanks!
