There are two memory slots. The memory is not soldered. Uses DDR4-3200 SO-DIMM and maximum would be 2 x 16 gb for 32 gb total. The model you ask about comes with 2 x 4 gig. The Manual says not upgradeable, onboard, and max 16 gb. All that is not true as you can see on p. 30 of the Manual.
Post back with any more questions and please accept as solution if this is the info you needed.
3. But in English version (does not exist in Russian) of Maintenance and Service Guide ( http://h10032.www1.hp.com/ctg/Manual/c06618426.pdf ) I found this information on page 1 (9 of pdf). It says the following: "Support for DDR4-3200 1.2 v, nonupgradeable, onboard system memory in 16 GB and 8 GB conƭgurations". And I don't understand, what is it "nonupgradable". Does it mean that 8Gb configuration cannot be upgrade to 16 Gb?
