I haven't looked into the pricing of computer hardware lately, and I was looking around at the websites of some local computer stores and noticed that a 2GB stick of DDR2 was around $60 for a decent brand (cheaper for generic brands) so I thought I might aswell buy two and get 4GB.

I know 32-bit Windows places a limitation on having only 2GB for user-programs (or 3GB for /3GB), since Microsoft reserve the physical (:?) and virtual addresses above 3GB for the kernel and drivers.

The kernel and drivers barely use up 200MB, leaving 800MB to go to waste. However, the best part of my plan is that my nVidia graphics card allows me to assign memory to graphics card (which exists in kernel-space). So I could assign the ~800MB of left over memory to my graphics card.

I work in a local computer store. Today I spent half an hour on the phone talking to a customer, trying to convince them that I hadn't ripped them off because they only saw 3GiB of RAM instead of the installed 4GiB.

The more people move over to 64 bit operating systems, the better.
