I was looking at some motherboards, and noticed that some had support for 4GB of registered ddr sdram memory and 3GB unregistered ddr sdram. I was wondering the difference between this is?? Better performance possibly???

Well DDRAM was devloped because there was a huge need for faster and better memory data processing, see CPU speeds went through the roof and once they managed to get past the 1GHZ barrier a year or so ago I thinka little more even, they realized that SDRAM and EDO and all these other types of RAM were unable to process the data as fast as the processor would "handle" it.

Basically Registered DDR uses the Read command differently and only registers data upon request, its ideal memory for Servers and High end machines that need alot of ram very fast.

So registered is better.

lol...I forgot I even posted this. Glad to see someone responded. Well thanks for the info psychogen. So generally would this kind of RAM cost more?? I'm assuming it would since the better something is usually costs more. Another thing, what brand or maker of RAM is particularly better?? Thanks again.

DDR does not cost more due to the fact that the machienes that make DDR were the same type of machienes that made SDRAM So DDR is pretty Cheap to find...

Well maybe not exactly cheap but compared to SDRAM it is not much off the same price, but once you get up to the 3 - 4 GB area it does get kinda pricy.....

I always have and always will recommend the brand "Kingstone Memory" the focus just on RAM and nothing else (last time I looked anyway) very good brand, never had any problems with any of their stuff!
