Help choosing RAM for X470 Taichi

   If the QVL says that it should run at 3200 MT/s (*) then that's the speed you should expect.  The potherings over Samsung B-die were much more of an issue in the early days of Ryzen, when they were still trying to decipher the Intel proprietary XMP stuff and matching it to their memory controllers.  Make sure your Taichi has an up to date BIOS and I expect you'll be fine.

(*) MHz is by definition a clock rate.  DDR memory does 2 transfers per clock.  DDR4-3200 runs at 3200 MT/s (million transfers/second) but the clock rate is half that, 1600 Mhz.  Even the memory manufacturers abuse the units these days, but Captain Pedantic ain't letting them get away scot-free...

	Hello I recently ordered a 2700x, X470 Taichi (non ultimate) and Kingston Predator 3200mhz I want to get 16gb (2x8gb) Ram that can run at 3200mhz and I'm worried the ram I've ordered although it's on the QVL's Supported Speed at 3200mhz it could have problems because it is Hynix M-die, I read after I ordered the Ram that Hynix doesn't work well and I should be getting Samsung B-die instead. So basically I would like to know if I'm getting worried about nothing and the Ram I've ordered is going to be okay and will run at 3200mhz without any issues or if not can anyone recommend any alternatives? Thanks. Ram part number: HX432C16PB3K2/16 QVL: https://www.asrock.com/MB/AMD/X470%20Taichi/index.asp#Memory
