@Serg008 I managed to install vanilla 48-in-1 msi ultimate on a hdd, upgrade that 10 on the same hdd, clone it to a nvme ssd, then mbr2gpt /convert worked so I guess I am OK, I got my locked CPU frequency at max turbo with 0x07 and Above 4G Decoding appears turned on when I view this with AMIBCP 4.55 so I thank you for the mod.
