I don't think the thread creator is the seller?

Why don't you lookup dideko's contact info and write them a mail or check their online shop?

Is this card compatible with any motherboard? What I am also curious is what happened to the heatsink....

I have currently 4 of these cards and tried them in several server/workstation boards from supermicro with x8 and x16 pcie 3.0 & 4.0 slots and they worked without problems.
An asus first gen threadripper boards (x399a or something like that) had random crashes that disappeared after a bios update.

Great, I put an offer for two cards, lets see how things pan out. The systems these will be going into are a bit legacy with v4 E5s but for the price it was worth getting them vs a 10gb card.

Yeah its starting to almost feel like a shame to buy 10gbe cards now with how much the price diffrence towards 25gbe and 100gbe is shrinking.
Think it was 65$/ea i paid for my last 25gbe connectx4 cards while the 10gbe cards i liked for esxi support was 50$.

Are those compatible with VMware 8.0 U1 running SR-IOV? Looked in the VMware HCI and found only one Mellanox there and zero NVIDIA.

The two cards arrived alongside the 100GBps connection cable. It worked out @300 EUR for the set of cards and a pair of cables. At the moment, the cards are connected back to back, the extra cable is for when I get tempted and pull the trigger on the 700 euro Mikrotik switch. The next step is to create a NVMe based iSCSI target on my TrueNAS and move all the VMs there. Just as a teaser, for a big single file transfer from 12 HDDs to a local NVMe, I am getting this, which is a starting point...
