Are all FRU for a particular Lenovo Marketing part number compatible/identical? (lemmy.ml)

I'm asking here since I assume a lot of you guys are running homelabs on Lenovo hardware.

I have two M720q Tiny that came with one 8 GB 2400MHz SoDIMM RAM each (see picture). I upgraded one to 2x 32 GB RAM and want to reuse the sticks in the other one for 16 GB in total and dual channel use. They have different FRU numbers (see picture) but I assume it's the same marketing part number and I guess my plan works?

Can anyone confirm? I'm just unsure about dual channel since it's not exactly the same RAM and I'm used to using exact pairs.

Thanks!

Depends on if they're the same speed. Faster memory has shorter clock cycles.

It doesn't really matter too much though. The system should just run all the memory at the slowest speed/timings.
