This ram is an oddball. It requires the motherboard to switch to 1.35V (from the standard 1.2V) to achieve better timings. I just watched an unboxing where someone tried using it in the framework and only get 2666Mt out of it.
I almost accidentally purchased it myself before I saw the 1.35V thinking all DDR4 sodimm was the same.
You’ll need to find RAM that runs at 3200 MHz without XMP. It can be difficult to find if you don’t know what to look for.
Typically it’ll specify 3200 MHz at 1.2 V with CL 22 (JEDEC standard).
For example, here’s a G.SKILL kit with 3200 MHz JEDEC: Are you a human?
Here’s the same kit, but with timings of 18-18-18-43 (CL 18): Are you a human?
Notice the second kit has “Intel XMP 2.0 Support” - you won’t know if it even supports 3200 MHz CL 22.
All of the options we directly provide (either pre-installed in pre-built or configurable on DIY Edition) are natively 3200MHz without XMP. The brand will vary on pre-built, while on DIY Edition we currently use Crucial (though this is subject to change based on availability).
From first hand experience the F4-3200C22D-64GRS kit definitely works at DDR-3200 on the Framework laptop. That Amazon question+answer is almost certainly a red herring on account of the responder most likely using a laptop not capable of supporting DDR-3200 JEDEC, perhaps Comet Lake based as taeyeon suggests.
