Memory error with new CPU, fine with old CPU

[elia111]

I recently upgraded my setup from

Ryzen 5 2600,

2x8GB Corsair Vengeance,

GTX 1660,

Gigabyte B450M DS3H

EVGA 600W Platinum 

to

Ryzen 9 5950x

2x32gb Corsair Vengeance,

RTX 4070,

ROG Strix B450F Gaming,

(still used old PSU because new one hadn’t arrived yet).

Everything but the Motherboard I bought new. First I installed all the new components and I got the yellow ram error LED aswell as no display output. I tried every slot, only one stick of ram, the old ram, a mix of both but i got the same error every time. Then I started just switching out components from old to new (as i knew the old stuff works). First the motherboard, then the cpu, then the ram, and that all worked fine. When I swapped the cpu over I got the same yellow ram error LED as before and no display output. But I know the ram works because the system ran with the new ram. Does this mean my cpu is dead? Or is there something else that might be wrong?

B450 boards DO NOT support ryzen 5000 out of the box at all. So most likely thats whats happening.

 

They'll refuse to work or throw odd errors

It's not giving it a shot , it's almost certainly the problem.

 

Your board will not support the 5950X otherwise.

 

The fact it's running atall is a surprise.

If you look on the QVL, what might be ok on Zen 1 and 2 might not be ok for Zen 3.

The 5000 series generally had a better memory controller than zen 1 and zen 2 , I would be very surprised if the same memory works on the 2600 and not the 5950X , I suspect OP is using an earlier bios than the F60 that introduces support for the 5000 series.

I updated the bios with the old cpu (had the 2019 version installed) and now it works great. Thanks!
