That sounds totally bogus. You don't have to update the BIOS to support Ryzen. Ryzen is the first CPU on AM4.
You don't need "DDR4-2133 sticks". Ever. Any DDR4 sticks can run at 2133, that's literally the DDR4 standard, everything above is overclocking. 2133 rated sticks are the cheapest (and worst).
I got my R7 1700 and mainboard yesterday. Everything worked on first try. Speaking of DDR4, my 2400 rated (Hynix) sticks overclocked to 3200, with decent timings, even :) (Well, decent for Hynix.) My previous system (overclocked non-K Skylake) couldn't run these sticks above 2450.
Why... why would I lie? What could I possibly have to gain from lying about this? I only have HN karma to lose, which I don't have much to begin with.
You can, before simply defending AMD, research and see for yourself that required BIOS updates are indeed an issue.
I tried it with an MSI Tomahawk, and an Asus B350 Prime.
Had a Ryzen-5-1600 and a Ryzen-7-1700, as well as a pair of DDR4-2133, and DDR4-3000 modules each, and tried every combination, and was never able to post.
Switched to Intel CPU and Asus Intel-supporting MB with the same DDR4-3000 RAM and POST'd on the first try. I'm saying that to 'prove' that the other components were fine.
I'm glad that it worked out for you, and I wish it had gone smooth for me too.
You messed up something.
My 1700 and Asus B350 Prime were able to POST without issues and without any BIOS updates, and I got both a couple of weeks after release.
Most BIOS updates have only been required for overclocking improvements.
