Hello everybody,

In a review, I have read that at equal frequency, the DDR2 have a
transfert rate two times faster than DDR but in the same time, the
global performance of the DDR2 is just above the DDR one.

What about that ?

In France, the price of the DDR2 is just 10 to 15% above the DDR price.
Is it a good solution to choose DDR2 ?

Thank you for your help.

Pierre.

Choose you CPU first, then buy what it needs.

It is a Pentium P4 520 2.8 GHz. and with a mathor board ASUS P5GDC
Deluxe that accept both DDR and DDR2. So ... which one ?

At the same frequency the bandwidth is the same. DDR2 has slightly higher
latency then DDR so at the same clock speed DDR will give you slightly
better performance. However DDR2 can operate at much higher clock rates
then DDR so if you are going to get a DDR2 system buy the fastest RAM that
your system can support.

Since it already supports DDR2, I'd go ahead and get it.
Not even counting the minor performance difference, it could
be worthwhile to buy memory with better long-term viability,
reuse potential. That would also mean buying larger
modules, probably, like 1GB each instead of 512MB each.
