content: Radeon Pro Engineering Sample card bricked, options? I bought a couple Ethereum rigs from this guy. One of the mobos was bad and possibly one of the cards. Unfortunately it is a $1000 Radeon Pro-Duo card that seems to be more of a brick than a card. These cards are awesome, I have had 3 of them running for 3 weeks straight [basically 6 GPU's with massive cores, HBM, and Cooler Master factory water cooling] I think the guy sold me a fried card. I can't prove that the card was bad when I received it.  Anyway, it was an Engineering Sample made by AMD in 2016. So I know there is no warranty, however I am wondering what my options are. I am waiting to hear back from AMD about what they might offer in terms of repair. I can keep the card for water cooler spare parts for my other 3 cards, or I can try and manually flash the BIOS with an IC programmer. [maybe 20 man hours for me to set up] Before I get into that; the card powers up but does not appear even as a registered PCI device. Maybe totally dead. I can not find any physical damage, smoked VRM's, melted power connectors etc. And neither BIOS selection makes a difference. [I did not update the BIOS] Any suggestions?
