Searching stock bios for Sapphire PULSE RX 5700 XT BE

[HaelSturm42]

Hi all,

as I managed to loose the original stock rom of my card (please see title and reference links), am reaching out here in hope someone has it. Card is slightly different to normal RX 5700 XT BE as it uses different memory timings from what I can tell (it also lacks the dual bios switch and capability).

I already flashed following rom file from the database 224726 which lets me somehow partly interact with the card as Long as it is only 2nd GPU, but leads to a black screen during windows and linux boot with a freeze of the complete system when I remove the other GPU.

Card is momentarily only used in that testing man cave rig, built with MSI X58 mobo, Xeon L5645 CPU, 24 GB DDR3 RAM, 250GB SSD, Win10 (latest patch set), Ubuntu 24.04 LTS. 2nd card to have a screen is an old R7 XFX.

Thank you and best, Markus

With help of TPU forum I could find a solution.

PFA there a mended bios version with 8 mbit / 1024k in size the amdvbflash 3.04e tool presumably requires to flash this special card. As it is equipped with a 8 mbit flash (GD25Q80) but not equipped with a bios “bank” switch. Hence amdvbflash reads 1024k (512k bios followed by 512k FF bytes) and expects a similar file to successfully flash.
