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.
