I record the normal flash I believe
https://prnt.sc/fvqdo1or
1. cmd as administrator ---> cd C:\atiflash_274
2. atiwinflash -unlockrom 1
3. atiwinflash -p -f 1 bios2200max-2100def-1750atallabove.rom (0 for first and 1 for second)
If what file name suggest is true (2100 default for mem) , then maybe you're actually lucky...
I have two micron based ones and with 1750 strap both top at 2050MHz
