So I'm running two Asus rx 480 8gb samsung memory cards and I'm trying to get them up to 29+ speeds for mining. I'm currently dual mining ETH and SIA but both cards are giving me at most 24Mh/s. So after going through many threads on here I thought I finally had it down. I did the following:

- Downgraded my drivers to 16.9.2
- Backed up my bios for both cards
- Downloaded a modded bios for my cards I saw posted in one of the threads
- Flashed both cards/rebooted
- Left MSI afterburner on default and tested the hashrate, saw no difference from the 24Mh/s max I've been seeing.
- Used afterburner and pushed the the memory clock, went all the way to 2250 and just ended up with a crash (on all tries at 2250). Also messed around with the clock and voltage, saw no change in gains.
- Some of my windows were acting wonky, transparent and took a while to load so I decided to revert back to the original bios.
- ATIWinFlash had my main card listed correctly and the 2nd card listed as AMD Polaris 10 even though the cards showed correctly in other parts of windows.
- Flashed back to the original bios and things are back to how they were.

So I'm back at ground zero. The name of the rom I loaded was "asusRX480strix8g_ubermix". I've been searching through thread after thread for the past few days and haven't been able to find an answer so if anyone can assist, I'd appreciate it.
