memory - Can I add a second SODIMM to a Thinkpad Lenovo P1 with the Xeon processor?

The Thinkpad Lenovo P1 with the Xeon processor (part number 20MDCTO1WW) comes with these RAM options:




  • 8GB DDR4 2666MHz SODIMM

  • 8GB DDR4 2666MHz ECC SODIMM


  • 16GB DDR4 2666MHz SODIMM

  • 16GB(8+8) DDR4 2666MHz SODIMM

  • 16GB DDR4 2666MHz ECC SODIMM

  • 16GB(8+8) DDR4 2666MHz ECC SODIMM

  • 32GB(16+16) DDR4 2666MHz SODIMM

  • 32GB DDR4 2666MHz SODIMM

  • 32GB(16+16) DDR4 2666MHz ECC SODIMM

  • 64GB(32+32) DDR4 2666MHz SODIMM




The fact that there are 8+8, 16+16 and so on options present, makes me believe it has two slots for RAM. I'm thinking of getting the one with 16GB DDR4 2666MHz ECC SODIMM; Would I be able in the future to upgrade to 32GB by adding a second SODIMM?



My question comes from my vague recollection that once upon a time you needed to get matched pairs of ram sticks and they would work individually but not (or not very well) with other non-matched sticks.
