Finding out latency to RAM
 
How do I find out the memory bandwidth/latency to RAM of the machine?

Do you mean other than 1) shutdown, 2) unplug, 3) open case, 4) push down end tabs of DIMM slot, 5) extract RAM module, and 6) read the label?

Or, other than googling a) the motherboard number printed into the board itself, or b) the make and model number of your computer?

Beats me!

For the actual memory bandwidth I use:

For the timing, you should probably follow hilyard's advice, but maybe lshw will show it ?

From my output of su -c lshw:

Code:

*-bank:0
            description: SODIMM Synchronous 533 MHz (1.9 ns)
            product: M471B5673FH0-CF8
            vendor: 80CE
            physical id: 0
            serial: 75F847F9
            slot: M1
            size: 2GiB
            width: 64 bits
            clock: 533MHz (1.9ns)

Perhaps the boldened part is what the OP is looking for in their output?
