RE: Dell Optiplex GX620 SFF no boot, no screen activity
Dear Chris, the parts you are mentioning are not sufficient to build a total of 4GB ram.
Anyways, for the knowledge of the community, the compatible memory sticks that worked with the dell
were SAMSUNG M378T2953CZ3-CE6. (2 sticks x 1Gb each)
I suppose 4 sticks of the same ram, should work with the GX620 as well.
Kind regards and thanks for the hospitality.
