But maybe we can try to overclock it?7D12 clock frequency is too low, it is of little value
and can only be started under a specific bios
the microcode is standard rome prod.unit. that's not the point.it seems that h11ssl-I v1.01 can recognize this chip, so can we extract the microcode and update other mono to use it?
"AMD processors are shipped unlocked from the factory, and can initially be used with any OEM’s motherboard. But once they are used with a motherboard with PSB enabled, the security fuses will be set, and from that point on, that processor can only be used with motherboards that use the same code signing key" (Source: AMD statement to STH)so anyone try to use it on h12ssl-i?
Can you paste the original post here, I just wandering if there is a way to disable some cpu pins to bypass those fuses."AMD processors are shipped unlocked from the factory, and can initially be used with any OEM’s motherboard.

if you buy a new 7D12 it will work on any rome supporting motherboard.
but if the 7D12 was once was ran on a dell it won't work on other motherboard than dell.

just look at the price. if under 500 USD it is a used one. cheap 7D12(OEM cpu) is left from Dell datacenter server (upgrade)It’s awful. So we should let seller test it on Rome mobo before we buy
See through the article, I figure out that:
the cheapest way to get arround this is to buy a refurbished dell motherboard.And just for my curiosity, what algorithm amd used in their fw signing
Or maybe we could extract the PSP fw from dell and then plant into our custom bios, but this base on the hypothesis that there is not any bios signed/verify procedure in EPYC bootthe cheapest way to get arround this is to buy a refurbished dell motherboard.
