memory - Don't understand these RAM specs


I was reading the RAM specifications for my motherboard, an Intel DH61CR, here, but I don't really understand what it is saying.


It says "16 GB maximum total system memory (with 4 Gb memory technology)".


The board has two RAM slots, so I assume that to get 16GB RAM I would install 2 8GB DDR3 sticks. But what does the "with 4 Gb memory technology" part mean? If I install two 4GB sticks of RAM, that would only be 8GB of RAM wouldn't it?


Answer



If you'd read a bit further down you might understand that "4Gb memory technology" means "SDRAM Density", there is a list of supported memory configurations below that spec list you pointed out. It explains this.


The highest supported memory unit is 8GB Double Sided(Means there are memory chips on both sides of the stick) 4Gb (SDRAM Density) RAM organized with 8x512Mb chips on each side of the RAM stick.


The way I understood it, SDRAM Density refers to the amount of memory stacked on one side of a RAM stick.
