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


If the RAM timings are not exactly the same, you’re going to have instability issues. This is why it’s always recommended to install pairs of the same exact model and brand, the clock timings.
I doubt that BIOS is going to give you the specs you need, but somewhere you’ll likely be able to find the timings and compatible memory for this machine. You’ll generally need something faster than what’s installed so it can step it’s timings down to be more in sync.
