[SOLVED] Newb here...can I mix memory sizes in this Lenovo desktop?

[Revived]

​ Legion Tower 5 (AMD) with GTX 1660​ ​
Configuration Details ● Processor: AMD® Ryzen™ 5 3600 Processor (3.60 GHz) ● Memory: 8 GB DDR4 3200MHz Just wondering if I can add a 16gb stick without issue?

Ryzen tend to be a bit finicky about mixing RAM. It would be best to get two matching sticks. With that said, don't think it will hurt anything to try. IDK whether your mobo supports XMP, but would go turn that off prior to installing the new stick and see if it boots. According to what the timings are on the other stick you may be able to bump them back up towards 29xx+

It's hard to tell....but from the service manual I'm seeing one slot.
Is there more than one slot?

There are four slots within.
