OEM recommended RAM as example aside from those listed in the hardware manual page 70-71 item 5:


PN 01FR301 8G DDR4 2400 SODIMM

PN 01AG843 8GB DDR4 2666 SoDIMM,Ramaxel

PN 01AG824 8GB DDR4 2666 SOIMM, Hynix

PN 01AG818 8GB DDR4 2666 SoDIMM,Ramaxel



Other ram with same specification should also work but always check on the return options just in case.


I hope this helps answer your query.
