Hi, i installed 2 x 4GB ram from different manufacturer, system only shows 4GB, tried different slots, still the same result.
RD210 3796, Model A17
Samsung M393B5170DZ1 - CH9 0948 / 4GB 2Rx4 PC3 - 10600R
Hynix HMT151R7AFP4C - H9 DB AA / 4GB 2Rx4 PC3- 10600R
Both have this label on them:
SUN(TM) PN: 371-4429-01
Their general description shows that they are exactly the same, however they won't work together.
I tried individual memory, they both work fine by themselves.
