Surprise: The ThinkCentre M75s gen 2 SFF seems this RAM as DDR-2400!
Why???
Even though it is advertised as DDR-3200, when you read the
specifications, it will only run at 3200 under XMP.

FACTORY TIMING PARAMETERS
• Default (JEDEC): DDR4-2400 CL17-17-17 @ 1.2V
• XMP Profile #1: DDR4-3200 CL16-20-20 @ 1.35V
• XMP Profile #2: DDR4-3000 CL16-19-19 @ 1.35V
XMP is an Intel "standard" and cannot be used by AMD systems (like the
M75s).
There are hacks for AMD. For example Asus' DOCP. But a business
computer line like the ThinkCentre is unlikely to use that.
Now I have to return a second set of RAM. Canada Computer might not
be as accomodating as Amazon.
I wonder how one searcsh for "DDR-3200 RAM, no REALLY DDR-3200 RAM".---
