I set my voltage up to 1.35 and timings and 16,18,18,18,36 and tRC at 55.
Seems OK so far. Ran a Cinebench which scored 7172 but did not crash which is the important part.
After searching for my RAM model it appears the Gigabyte XMP issue is common. I was just a little freaked out as it happened when I started cranking stuff around in BIOS. I might wait a few days before I start trying to replicate the Ryzen Master config into the BIOS :)
Thanks again
