For changing the BIOS L[1/2/3] cache settings, these are laptop BIOSes
which usually have very few features (other than secure boot/tpm
options which are required for laptops with Windows), so there was no
option for that in the BIOSes. However, when I get home I could try
changing the cache settings on the Legion 7i gen 5, as it has a key
combination in the BIOS to enter an "Advanced Mode" with overclocking
settings and more, which likely has cache settings.

None of the memory modules were overclocked, and they were all
operating at stock speeds. The Legion 7i gen 5 got 10 passes in
memtest with 0 errors, and both of the Thinkpad X1 Carbon laptops, and
the Yoga C740, had fully soldered memory. One of the Thinkpad E14 gen
5 laptops also had unchanged memory. The laptops without any changed
memory also showed similar results, so I doubt that it has anything to
do with memory.

Have an exceptionally great day,
