I need help fixing VGA bios to make crossfire work.

[Joshua3338]

Hi there i have gotten myself in a really bad pickle, the two cards i ordered have different bios versions and won't work with crossfire fully. the problems are when i enable crossfire my other monitor turns off. i have two monitors. the two video cards are: powercolor pcs+ R7 370 2GB. its kinda of a problem and i can't locate a up to date bios and flash both correctly. i understand how to flash. i was thinking of maybe copying the bios from other card and use that one across both cards. idk im lost here i need help. im using ATi winflash utility its the one that seems to work with windows 10. i don't do any bitcoin mining. i just use the computer and play games no bitcoin mining here.

i have not found an updated bios for these two cards i can't seem to find.

you do not have a problem only an understanding failure of Crossfire
when enabling crossfire display is shunted to main display and any secondary display is blanked/disabled

No bios flash will resolve this; as it is by manufactures design

As you can see from the above Charts Crossfire is designed to work with different cards different Bios revisions and mem configurations
what matters is the Gpu Class of chip on the Different cards
GPU and mem Will default to lowest Card Values of the pair involved that is both GPU speed and mem Size and speed.

In this Respect Crossfire is Superior to SLI
