I have a e14 Thinkpad gen 5 Intel 1335u with 8gb soldered ram and a 8gb 3200 ddr4 stick. 16 is not enough ram for my use as a developer so I put a 16gb stick in knowing only first 16 will run dual channel. Now my computer crashes randomly with high memory usage… read online that a 32gb is more stable single channel but I’m skeptical. Stability is pretty important to me as this is how I earn a living what do you all think? Also I would just buy a 32 and try it but everything got pricey the last 2 month

EDIT: ran memtest after crashes got worse, went back to stock 8gb and gave up. Some weird issue with used 16 stick
Reseat the stick you installed and run memtest 86.
It’s more likely that you have a badly installed stick or a faulty stick than consumer memory controllers in the last 20 years care about the installed memory being the same.
