I have replaced my old 1st generation Threadripper with a new Ryzen 9. It was surprisingly smooth and works really good.
The only thing I had to take a minute to fix was a error when starting VMware Workstation about AMD-V not being enabled as required.
Going through the menus in the BIOS on the Gigabyte motherboard I found nothing about "AMD-V". But a quick search on AMD-V revealed that AMD-V has been published as AMD Secure Virtual Machine (SVM). And this I could find in the BIOS menus:
- During startup press <Delete> to enter the BIOS.
- Select "Advanced Mode (F2)".
- Go to "Advanced CPU Settings".
- In the Tweeker menu you pick "SVM Mode" and select "Enabled". Then press <Enter>.
- Select "Save & Exit" then click "Save & Exit Setup" and finally "Yes".
