How to activate the 8 cores of the Ryzen 1800X? I activated it by the S. Windows 10 (msconfig> general> advanced options) but when I check in the task manager it only has 4 working. This is normal?

jailsonliima, this is not normal.  I suspect you have a stale copy of W10.  Please install a fresh copy of windows.  Please post your specifications and tell us where you got your copy of W10.  Envoy, John.

EDIT: Always install the latest version of W10 (1803.17134.376 right now due to MS problems, please do not try 1809).  I strongly expect NO RMA is needed!

I have tried the Ryzen processor with the win10 (1511) version.

8c/16t can also be correctly identified on the 1511

However, I still recommend that you update win10 to the latest version.

This problem still exists if you update to the latest version

Please try to contact AMD for RMA

However, if you really bought the Ryzen 7 1800x with 8 cores and 8 threads, I suggest you not to do RMA, but put it in the box and collect it.
