Checking memory type

Is there a command I can run to determine the type of memory that isinstalled on the system?

HDT does a pretty good job.

I'm hoping to add some memory to a system and want to be sure I get the right type.
 
Try sysutils/dmidecode:
Code:
...

You can try "dmidecode". It will tell you all about your RAM, among many other things.

pkg install dmidecode

Here's info about my RAM provided by dmidecode"

Here's what I got - a bit overwhelming.... I guess I need to run it with some parameters...

Your processor support only DDR3 1066 (PC3-8500). So the memory that you will going to install should support PC3-8500 data transfer rate. If you put PC3-10600 it will run at lower clock rate.
Do not mix different memory modules.

Supports 1GB, 2GB, 3GB, 4GB, 8GB memory
SoDIMM DDR3, PC3-10600 1333MHz DDR3, two SoDIMM slots
