AMD RX VEGA 56, reference model, tested and working.
These cards were used for compute in a datacenter, so they've been modified for that environment. The end of the main mounting plate has been cut, and the fan, shroud, backplate, and PCIe cover plate are missing. The heatsink is in good condition and runs well with an external fan, but will need some work to run in a desktop. (On the other hand, it'll drop right in to most rackmount servers.)
Card works perfectly, tested with external fans. I've verified all display outputs, tested the GPU with shader-intensive graphics, and used it to run small AI models. (Docker model runner makes this super easy, these days. Really impressed.) Also, GPUTach is an amazing feature that I'd like to see in more cards. I've included a couple of photos of a card under test -- note that fans, power supply cables, and similar are not included.
