RD210 only display 4GB?

Hi, i installed 2 x 4GB ram from different manufacturer, system only shows 4GB, tried different slots, still the same result.


system specs:


RD210 3796, Model A17


Memory 1

Samsung M393B5170DZ1 - CH9 0948 / 4GB 2Rx4 PC3 - 10600R


Memory 2

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.


Help please?
