I was thinking to change my 2*256 SDRAM PC133 memory's chip with a 512 DDR
333 (my motherboard support both).
Who know the improvement in performance in such change (the system is a P4
2.53)?
In other words: is it convenient?
Thanks

I've read similar questions to yours before and always read the threads -
i've got a ECS K7S5A Pro with 512MB PC133 RAM and wondered what the
performance gain would be to upgrade to DDR memory - it supports a maximum
of 266 DDR memory.

The answers tend to suggest a 10% performance gain by using 266 DDR compared
to PC133 memory.

So maybe a 'bit' more may be gained with 333 DDR memory...?

I doubt that increase is only 10%, since DDR RAM has 100% more data flow
than old one, so if gain would be only 10%, then DDR would be history long
time ago.
I think it's lot dependant on mobo and CPU. IF mobo and CPU isn't capable of
reading/writing at double speed, then it's no point of using DDR. also
depends a lot to which program do you use - if it works a lot with RAM, then
increase is bigger (like graphics programs etc.)

The performance boost with higher speed memory depends on many things, e.g. the size of level 2 cache. The improvement with faster memory would be much greater with a Celeron with 128 Kb cache than a Pentium 4 with 512 Kb cache. Going from 256 Mhz to 333 Mhz will produce a significant difference in benchmarks but not a big difference in overall system performance.
