How can I verify the type of memory that my freebsd box supports?

Question

I have an old pfsense router and want to see what type of memory it supports (e.g. DDR2 240 pin... PC100... DDR... etc). Is there a command that will show me this?

I know I could just open the box to look but I don't want to introduce downtime unless I have to.
