Hi,

I purchased an AMD Ryzen 5 1600 and an MSI B350M Gaming Pro motherboard from Amazon (UK) presuming that they would work. When I powered up my PC for the first time, all fans and LEDs switched on however it did not post. Instead I got a red CPU fail/not detected light on my motherboard. I ran through most usual diagnostic steps such as 8 pin connected, CPU correct orientation, no bent pins etc.

After some research I found out that some motherboards are not compatible with R5 CPUs until after a BIOS update, which requires an R7 CPU. My motherboard had been listed somewhere as a board that wouldn't work with R5, but I also had seen videos showing it had. I presume that some of the boards have had the BIOS updated? Or perhaps some people and myself have a bad habit of damaging CPUs!

I rang Amazon and they said I would be able to return the board (and get a refund), but I am not sure what board I should get instead. A mATX board is probably best because of pricing.

Would anybody be able to offer some guidance, it would be greatly appreciated!

Sam

Ryzen supports 2933 Mhz not 3000 MHz.

Sometimes even raising the memory voltage slightly, by a hundredth or a couple of hundredths of a volt, will make the memory work.

The memory controller resides in the Ryzen...
Being able to reach the higher speed memory's stated speed rating with Ryzen is still a crapshoot.

Sometimes you'll be able to reach the full stated memory speed with a one model of Ryzen CPU and another model of the CPU will fail to POST at the full stated speed even with the motherboard's BIOS updated to the latest version.

Hi, thanks for the quick reply!

I've got 2x8gb DDR4 Corsair Vengance 3000mhz ram. Could the 3000mhz be the issue? It was the CPU LED and not the RAM LED that came on though,

Cheers, Sam

Has the system ever completed POST?
