How to check if RAM pair is matched or not?

[prady16]

I just bought a 1GB stick of Kingston 667MHz, PC2-5300 DDR2 RAM.

My MBP came with one Samsung RAM.

I have made sure that the speed and size of both the RAM's match, but i was wondering if it really makes a "matched pair"?

Is there a piece of software or a script which can determine if the RAM pair is matched or not? I tried running the following command in terminal, but it returned nothing:
ioreg -p IODeviceTree -n memory -S | grep ram-

Thanks in advance.

When people say "matched" RAM they mean the same brand and size and speed.

Layman's terms:

1G + 1G = matched pair no matter brand... << runs @ full speed (667 mhz)

1G + 2G = unmatched pair.. << will run @ half speed of ram speed (333 mhz)

I would have to disagree about the brand. It is always a good idea to have the same brand if posible, especially as cheap as RAM is these days.
