Motherboard: ASUS Ai Series P4P800-E-Deluxe
Chipset: Intel 865PE 3.2 GHz = P4 CPU on 800MHz FSB

My computer will accommodate identical, matched sets of RAM,
such as, PC 400 DDR DIMM Non-ECC

Some web sites stress the need for identical, matched sets of RAM.
But some computer sales people say that matched sets of RAM are not necessary.
One can have just as good results by purchasing two of the same type of RAM.

Please advise me on what is true?

How much improvement do the identical, matched sets of RAM provide?

I am a novice.
I know the kits of identical, matched sets of RAM are much more expensive.
And my funds are limited.

Thank You for advising me.

Yes, matched RAM is important, and usually even more important for Windows
than it is for the motherboard itself.
 
Identical ram from the same mfg might be benificial but very doughtfull.Where
one must be concerned,have the same mhz,the critical area,do not mix dual
sided ram with single sided.
 
Using matched sets of RAM is advisable for motherboards that use Dual
Channel technology, as does your motherboard. Non-matched modules may work
correctly, but it's less certain. For single channel systems it rarely
matters at all.

I've got several computers that are dual channel and have different type
an vendors ram in them, as an example:

DDR400 Dual Channel x 512MB
DDR400 Dual Channel x 512MB
DDR333 Dual Channel x 256MB
DDR333 Dual Channel x 256MB

In that system it only runs as fast as the slowest ram, but it's rock
stable.

If you do something like this:

DDR400 Dual Channel x 512MB
DDR400 Dual Channel x 512MB
DDR333 Single Channel x 256MB
DDR333 Single Channel x 256MB

The BIOS/board will revert to virtual single channel mode, since both sets
are not Dual Channel, and it will run slower.
