I've got a Fujitsu Siemens PC (purchased in the UK) which has a motherboard that has 4x DDR400 RAM slots. The board supports Dual Channel RAM. Currently the system has 1x 1GB RAM Module installed. The owner wants to increase the RAM to help with performance. What do you guys think would best setup for this PC RAM wise...

2x 1GB RAM Modules (2GB) - Setup as Dual Channel
3x 1GB RAM Modules (3GB)

PC = XP Pro, P4 3.2GHz CPU, Gigabyte PCI-E Graphics Card, SATA HDD

Cheers. :thumbs:

2x1GB and 2x512MB = 3GB or 2x1GB = 2GB

I wouldn't get 3x1GB.

Use dual-channel if you can (ie use matching sticks in slots 1 and 3, 2 and 4)

I'd just get 4x1gb, even if you can't see it all if the ram isn't too expensive...

What is the computer's model number?

It's a Fujitsu Siemens P320 1915G....

I've got 2x 1GB RAM Modules in there at the moment and the system seems to be running sweet as!

No use in getting 4gb of RAM unless you've got a 64bit OS, Windows will only recognise around 3.25gb of RAM

And it probably wont work with 1 stick of 4 GB.

Unless the slot supports up to 4 GB

More ram in single channel mode is your best option,provided your doing tasks that will make use of 3GB of ram.

2 x 1 gig = 2 gig = Dual Channel
2 x 1 gig + 512mb + 512mb = 3 gig
