Making sure my Macbooks all fine...

[FleurDuMal]

I want to put in two 1GB sticks of RAM into my new laptop, but before I do that I want to be 100% sure that it is all in working order. So far, in general use, I've encountered no problems with the Macbook.

However, I was wondering whether there are any freeware apps outthere I can use to check all the components are working fine? I know of coreduotemp to test my Macbooks temperature, but are there any others?

Thanks.

Involves going into the command line by holding... Funny Apple Key and S on startup, but works like a charm.

Not 100% reliable though, cos at the end of the day there is always that little bit of memory that is occupied by the kernel and stuff which can't be tested, even if you are on the command line.

You can also use the GUI extension (Rember IIRC) but that is absolutely useless, so much memory would be addressed by the desktop and extra crud that you barely get to test anything.
