Is it OK to flash a 256k original factory bios with a 512k modded bios on a Sapphire RX 470 8gb? I have checked them both in polaris bios editor and the data checks out OK on both. Only the filesize is different.

doktor83 was kind enough to send me this modded bios but I can't get confirmation from him via PM if it is OK to replace a 256kb factory bios file with a 512kb bios file.

ehhhhhhh It depends but should be okay. You have a nitro right ? So you have a dual bios switch ? if it messes up, switch it to the other bios and you'll be fine. edit: if it explodes and leaves a crater where your house was...i'm not responsible

Well it turns out the different bios size was due to the fact that I was backing up with GPUZ rather than ATIWINFLASH. I have flashed all my bioses successfully today but I am still getting a niggling problem with the claymore miner crashing on startup. I get the generic windows error " EthDcrMiner64.exe has stopped working, windows will attempt to find a solution online etc...." i had this problem three days ago before flashing the bioses so I know it can't be that. I managed to get rid of the problem but I can't exactly figure out what I did.

Is it possible to have a problem with a PCIE riser when both Windows Device manager and GPUZ are both reporting that all six cards are working perfectly? I also tried to add the command -GSER 2 to the startup batch file but it hasn't worked. The current crimson driver version is 16.7 or 16.8 I think.

I also read this article about bios signature check being re-enabled on crimson 16.12 drivers which means that any polaris edited bioses won't work. Is this true? https://www.techpowerup.com/228536/amd-bios-signature-check-re-enabled-with-relive-locks-out-polaris-bios-modders

Does anybody have any suggestions how I can get rid of this crashing issue? I had the miner running for 42 hours straight before today and I want to get this sorted.

Well, only 16.9-16.11 doesn't have bios signing
