Memory type

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View

I read lately an article in a local newspaper, that stated that if I have a
motherboard that is build to use PC3200, I could also use PC4000  and even DDR2
memory modules

What I would like to know is , IS this true, I know that I would not get the
whole performance gain from those memory module, but is it possible to use the
higher speed modules

Thank you in Advance

Merci a l'Avance

DDR has 184 pins.

You can use either PC3200 and PC4000 in a board designed for DDR.

DDR2 has 240 pins. It can not be used in place of DDR.

Most new Intel boards use DDR2.

The speed rating of a memory module is its tested maximum. It can go slower
and might even go faster, but cannot be guaranteed stable if run over its
rated speed. Its like a car that is claimed to do 120MPH. It doesn't have to
go flat out. It might go faster (down hill with following wind), but you
might damage it.

I think DDR2 is a different physical size though, so won't work.

You could use PC4000 DDR(1) modules, either running at
PC3200 speed or at higher speed if your board supports it
and is stable doing so.  Typically only an aggressive
overclocker would do so.

DDR2 won't work in your board.  Won't fit, because it
wouldn't work if it did fit.

The best performance is typically running at same clock rate
as FSB, or in some cases the +33 async mode, and the lowest
timings the modules and board support.  So if your CPU and
board dictate PC3200 memory speed, get modules with 2,2,2,5
timings... though just because the module supports these
timings, it doesn't necessarily mean the board would be
stable, and shouldn't use them anyway if you also have other
modules with slower timings installed simultaneously.

Re: Memory type

You CANNOT use DDR2 modules in a DDR socket.
