Another reason for you guys to upgrade to Vista if you haven't so. With Windows Vista Service Pack 1, now you can see the full 4GB RAM in your system even if you are running only 32bits version of the Operating System.
Yes, too good to be true, same as most other people out there, I'm excited and happy to have 4GB shown in my laptop, only for the few minutes.
The fact is that, SP1 only changes the Windows OS such that it will DISPLAY the total RAM installed on your system rather than the USABLE by OS.
Oh microsoft, I hate it!
Well, RAM is dirt cheap nowadays that I've just upgraded my laptop from 2GB (2 x 1GB sticks) to 4GB (2 x 2GB sticks), and that cost S$60. The prices started to go up somehow, I was told by the shopkeeper that 4 hours ago it was S$28 per 2GB stick.... :-S
And ofcourse, I bought the Kingston, very cheap RAM.
