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

100% untrue. While a North Bridge controller can detect and attempt to set the clock frequency, there is absolutely no way to tell if both pieces of a mismatched pair will actually support the timings suggested or set by the controller, which will almost certainly default to whatever the on-board memory supports.

That along with the unknowns of whether it attempts to set channel ranks, which is almost certainly NOT an option to manually configure in a Thinkpad.

Not sure where you heard otherwise, but you've been misinformed.

This machine is also working with memory soldered on the board which comes with a whole host of other unknowns, which is why you look up what the timings are first and attempt to match that.
