just an update:
so, i bought as close as i could find to the 8GB samsung memory, and guess what… it worked!!
its only 8GB but things look stable so far, performance is pretty nice compared to vision five and MUCH improved compared to high-five unmatched…
btw, i’m gonna try a 32GB ( MTA18ASF4G72PDZ-3G2E1) stick from the aforementuioned thread and report back
here is the detail
this 8GB stick worked for me (for v1.3 pioneer board)
Samsung M393A1K43BB1-CTD memory module 8 GB DDR4 2666 MHz ECC
