Pretty much a novice to memory - but a quick question. Are there real advantages to having say, 2 512 Sticks running dual channel or 1 stick of 1 Gig? The memory type is 240 Pin Unbuffered.

The best reason is if one gives up the ghost your machine will stay running until you get a replacement.

Not a small detail BTW. I never build single module machines for just that reason.

I cannot comment in terms of how tangible the difference is to the user but in theory it could make a big difference. It depends on your system.

Two modules works out cheaper than one big one.

To get the best performance possible from your system your total memory bandwidth should match your FSB.

For more specific advice give more details about your system. The fact that your PC is only 1.5GHz and supports DDR2 seems strange to me.

If your Intel MBoard supports dual channel there is a definate advantage to using it.

Thaks for the followups. I should have elaborated that the new memory setup is for a new build that supports dual channel with 240 Pin sticks. The system being referenced in this post is a P4 3.2 w/HT and will sit on an Asus MB (775). There are 4 Memory slots. Sorry.

Thanks

In that case I really suggest to use two
ram sticks. If dual channel is really
supported by the controller it can speed
you up quite a bit because the system can
use 128bit to send data to the ram instead
of 64bit.
