Hi Steve, I was hoping you could explain why when you put 4 gigs in a 32 bit system you only see 3 gigs or 3.5 gigs not 4. It has been my understanding that it is because the 4 gigs that the is used by the computer includes all memory in the system including bios, video cards, sound cards, etc. In other words if you put a 512 MB video card in your system and you also have a sound card with 256 MB your main memory will be limited to less that 3.25 gigs. Please let me know if I am correct and if not exactly what is the cause of this

Thanks in advance

You are basically correct, except that video and sound cards do not consume the amount of RAM that they contain on-board. You'll see some detailed information I posted on the subject here: viewtopic.php?p=66#p66, and here: viewtopic.php?f=3&t=74&hilit=4gb

Scott (aka Steve <g>).
