I purchased an AM5 board about a year ago to prepare for a Ryzen upgrade. After two bad Intel boards, I moved to Ryzen. I’ll receive the CPU tomorrow and pre-built the system using BIOS flashback to ensure it’s up to date. It functioned correctly, but I attempted to power it on directly. Since I’m unfamiliar with AMD MOBO, I’m unsure if it needs a CPU or if another defective board is involved.
Your AM5 motherboard probably won’t turn on without a CPU installed, which is unusual but possible with some boards. Because BIOS flashback is functional, power is reaching the board, indicating it’s likely working. Make sure your power connections are secure, but the main challenge is installing the CPU. If it starts up, the board only needs a CPU to boot; if not, it could be defective.
resembles LGA 1151 but includes a SKTOC pin. Likely mods exist to adjust the SOC chip for testing. Probably not needed on AM5 unless for hardware voltages or diagnostics. Feasible.
You might think it’s pointless since it could cause problems, but it might just delay your CPU performance.
It’s just one day. Keep waiting. Why did you purchase this item a year ago without using it? (Or at least try it out). If it turns out to be defective, you won’t have any guarantee.
