Any help getting me to a point, where my card has an EFI boot ROM, would be greatly appreciated.įor work, I build out a lot of boot drives for workstations, as well as create/modify bootable USB sticks for troubleshooting system issues.

(I needed a card with a blower fan, since all my other slots are populated, and just need a better way to exhaust the heat.)Īnyhow. The card I have is an MSI Sapphire RX580 8GB Reference card. I just have never flashed a chip before, but I'm willing to put in the effort Also, no answers to whether or not the EXP2010 is necessary, vs the newer EZP2013 or 2019.

A YouTube video mentioned the flash chipset AT25DF-041A, but there seems to be over 10 different versions of that chip, with different specs (voltages and clock speed) on the DigiKey site. Anyhow.Īre there any alternatives to MacVidCards?Īnd if not, are there any thorough DIY tutorials on how to modify an AMD GPU to add the EFI ROM? I understand there will be soldering, and I understand I will need a Windows system, but I'm just having some issues finding exactly what parts would be needed. Looking around on the web, it seems this is a common occurrence, these days. Emailed about 10 more times, since then, and I've received no response. Now, I sent an email 8 months ago, which he still seemed great, quickly replaying that I could definitely drop off my card on a weekend. Every one of those times was fantastic, albeit, he was getting harder and harder to get a hold of, over time. I've dealt with Dave from MacVidCards a bunch of times, first with an HD6870, then a GTX760, then a GTX970.
