If you're referring to later drivers blocking modified BIOS, I've run latest ati patcher with all attributes "found" and successfully patched, restarted and the error is still present. I do think the memory labels in BIOS editor showing up scrambled is a sign that this could be a new revision that the usual tools don't 100% work with. I've also tried the old Catalyst 16 driver with the Safe Mode - F7 then patcher trick without success.
I guess you are the one who wrote with this problem to my e-mail so we can resolve it there. For others it's probably because autoupdates of drivers. So use DDU uninstall drivers and block autoupdates, reboot, install new drivers and Pixel patch. It should be fine now. If it's not it might need use DDU one more time. It could be also bad riser maybe or too many GPUs. Windows 10 has max 8 GPUs. If you are not running Windows 10 so the max are 5 GPUs I think.
