DDR4 OC limits for Gigabyte Z390 M GAMING

I was surprised to see that Gigabyte limited their DDR4 OC speeds to 2666, on their Z390 mATX board—compared to ASRock, MSI, etc that OC over 4000. I don't actually push OC to extremes on my existing box (I prioritize reliability but try to get higher than rated speeds). I have not even evaluated whether CPU clock speeds vs RAM OC are more important (how much might I even notice, say, 2666 compared with 3200?)

Might Gigabyte increase their DDR support with BIOS updates or are such speeds baked into the hardware?

Well, ain't I stoopid!! I had looked at that PDF before I posted, here and was looking at the "native" column, not the table-titles. That was the only thing keeping me from ordering that board.

Thank you.
