Only if his O/S can handle all those memory addresses, 64 bit windows
can but 32 bit windows can't[1]. How many addresses can his O/S handle?
Incidentally isn't the amount of RAM accessible limited to 3.125GB in
the BIOS of the 530
[1] Theoretically it can but there are lots of reports about 32 bit
Windows only "seeing" 3.5 GB. Quite often this 'lost' memory has been
reserved for on-board video but with the Inspiron having a separate
graphic card all bets are off.
On 32-bit W7, look at:
Control Panel\All Control Panel Items\System
It will tell you how much is usable. I see quite a lot of HP boxes at
3.24 GB - but it varies.
This might be useful. I've got it on two XP PCs, but I can't remember if
I put it on a W7 Pro laptop.
