The 1500x/1600/1600x have been supported since BIOS version F1.

You don't 'need' to update it to support the CPUs, no.
Whether you want to update the BIOS or not, will depend on what's been implemented in each revision.
Thanks mate
The 1500x and 1600x should be fine.
Some of the 1600s take F20.

But the 1600 AF says f20
