Thanks, but for 1150 Asrock H97 Performance users it would be great to get an
Microcode update as well (and not to be stuck with 0671/10 from 2015/05/07 that
suffers not only from these MCE but also elision lock crashes).

BTW: thanks to UBU I was able to inject Microcode 0671/13 into the UEFI. MCE
still fixed, but still elision lock crashes (as confirmed earlier in this
thread for this Microcode).
