hi, i try to make a crossfire with hd6850 (ATI), and a 6870 sapphire but when i launch a game i have a nice BSOD.

all AMD partner as update HD6850 BIOS for fix that, but for us who have a basic HD6850, no bios. i try to flash with many other sub vendor bios but they dont work, it has almost worked with PowerColor but there is a shift in the hex must do all screwed up..(MY ROM as only 64kb !? Chinese scam? alpha rom? )

you can look the GPU-z  (look at the beautifull 113-xxx-xxx bios version  ) (i change the PCI-E to 16/4 on bios after screen this)

can someone help me?

Best regards

 

ps: motherboard P8P67 last bios version / i7 2600k / Win7 64bit last update / chipset last drivers / Vertex 4 256Gb / PSU 850W gold

 

pss: i have already proper uninstall drivers /reinstall // try to install one card first then the second // try the both // try underclock the 6870, etc..

What the hell? PCIe 2.0 x16 @ x1 2.0? And even at x16/x4 it's to slow for a 6800 series Crossfire.

Yes, but flashing a VBIOS should never be done unless instructed to by whoever made your card.

ATI stopped making cards themselves long ago for the retail market, quite possibly you have an engineering sample if the card itself has AMD (or ATI)
