I can actually swap chips on video live and pop one chip after another showing chips post/not post at a fixed odt setting.

My 1800x for example posts @ 3200 like a normal chip should...but to exceed 3200 require 48 ohm for 3333,3466 and needs to step up to 53 ohm for 3600-3733.

This is all on taichi...but i doubt boards will vary much.

Basically if you can boot @ 40 ohm over 3200 you have a damn good imc...

Msi is still or was still on 1004. Fairly certain without a unicorn imc...3466 and up...not happening at least not stable.
Chew, have you seen bios 1.73? It has an additional 8 or 9 memory settings. As you said I can not get over 3333mhz. On 1.73 bios I got there without disabling BGS. Of course that was on 2 dimms. I have yet to figure a way to get above 2667 on my 4 dimms of Flares X DDR4 3200. I think it is time for me two put the second 16GB dimm kit on sale on Ebay. At least I'll have a down payment on my Vega card that I'll buy in 2 months.
