These Laptops come with an AMD A12-9720, some sources say the passives aren't installed. Some say they are, it doesn't matter,etc,etc. No real concrete information. I have the solder station, flat tips and microscope to ensure this is a solid installation if I can identify the specific type of socket to purchase. I already purchased the matched pair of ddr4-2666 2x8gb kit at crucial and kingston's websites recommendation that it had 2 slots.. I was enthusiastic and didn't open the bottom up to see a single socket/slot.
Either way, a challenge to the Electrical engineers: 260 Position SODIMM DDR4 SDRAM Socket Surface Mount, what angle? and reverse or not? So I know what to buy.
Will post a video of installation and proof of function or not for the forum, if identified.

    A practical solution is to return the matched pair in exchange for either a single 16GB or 32GB DDR4 sodimm. Jack E/NJ

    While that would serve the purpose of increasing the available memory. Allow me to fully disable the paging functions in windows and, at 32gb, add a decent 18-22gb ram-drive. I am looking to increase the through-put and quantity of this system's memory.
     I realize the real-world SDR to DDR performance gains are not really even noticeable by most, but I already purchased this kit on the Canadian Craigslist and it's not returnable(although re-sellable).
     A DDR4-SODIMM slot/socket is about $10 max depending on the specifications and manufacturer, so if the passives are installed on the board then I can fairly easily do the installation and have either DDR or 2-slots and be able to upgrade my 16gb kit to 32gb for a reasonable price.
     Basically I'm looking for an answer to the original question. I am aware of the alternative options.
    Photo is my board with the memory I purchased, 1 sitck installed, running underclocked with it's tighter JEDEC timing profile as expected.
    **JEDEC via CPU-Z**
    *Tightest ddr* 2666-cl19-19-43-61
    *As running in sdr* 931.4-13-13-30-43
    (In the specs I read a slower CAS Latency but a true response that's 7ns faster, without going all the way down the spec sheet.)
