Next BIOS update for Prime Z790P?

[IlCode85]

Hello,

The last BIOS for this motherboard dates back to November when the Intel 0x12B microcode was introduced. That BIOS has the problem that C1E states are forced on and cannot be disabled. Since then other Z790 motherboards of the ROG series have received a BIOS update that allows the C1E states to be disabled. When will that BIOS update come to the Prime Z790P?

After further review and confirmation, we would like to inform you that the BIOS update for the PRIME Z790-P, which includes support for manually disabling the C1E power state, was released on March 28, 2025.
We recommend updating to this version and clearing CMOS before checking the relevant settings again.
