Problem with starting the Ryzen 5 system.
Problem with starting the Ryzen 5 system.
I placed a Ryzen 5 (5000 series) and an MSI B450 motherboard. After setup and booting, the screen stayed blank. A small LED on the motherboard showed a CPU issue. I checked online and found this model has known problems. I ordered another one—Gigabyte B450 M. D3S Wi-Fi. I didn’t mention that the PSU is Corsair CX750M (750W). This time, after installation, nothing worked. The CPU fan didn’t spin, even though the PSU was on and the mouse lit up. There seems to be a power issue.
All AM4 boards need BIOS upgrades to work with Zen3 processors.
You need to complete your assignments. Consider using a motherboard that supports flashing its BIOS via USB without a CPU, or update your existing CPU to Zen2 (if you didn’t receive an outdated board from 2018). You can also directly flash the EEPROM using a programmer.
I placed the B550 with a Ryzen 5000 BIOS. What options do I have here? Get a Ryzen 2600 or any affordable Ryzen chip, or swap it with a friend’s older Ryzen processor. Alternatively, consider a new motherboard for the B550. I think you’ll likely find an old Ryzen CPU for about £30.
With a B450 board you might catch a chance, but don’t depend on it. Even with B550 models you’ll need to update your BIOS to make it work properly—like with a 5600 (non-X) or 5800X3D. Always opt for a board that includes BIOS flashback, since some budget options now offer it. That’s why AMD requires BIOS flashback on all AM5 motherboards.
