RAM- Registered/Unbuffered

I am building a computer and when looking for memory it says Registered or Unbuffered. What does this mean? The one I am planning to use said Unbuffered is this good or bad?



Thanks,

Colin

registered and buffered ram is usually reserved for servers. I'd guess at 95+% of desktops are using nonregistered unbuffered ram.



Registered RAM contains a "register" (wow!) to aid in ensuring the data is being handled correctly, delaying all data from being transferred to the module for one clock cycle. The registers re-drives the signal throughout the memory chips which in turn allows for each module to be built with more memory chips, a plus for systems which require registered memory for sure.



Buffered is just a re-drive, no error checking

Its only bad if your machine needs buffered memory (i.e., Socket940 Athlon64 processor)

I am going to use an Athlon 64, so that means I need registered ram? Its a socket 754.

the ram contorller is on die so the cpu specs will say what type of ram it needs

I don't see anything about ram, this is the processor http://www.newegg.com/app/viewProduc...factory=BROWSE



and this is the ram I was planning on using, http://www.newegg.com/app/viewProduc...factory=BROWSE

the cpu wont say what it need. The motherboard you chose should tell you what type of ram you need.



I dont know about socket 754 but I have a socket 939 amd and am using unbuffered ram. I believe that only the socket 940 require registered ram.

754 does not require registered/buffered RAM. Only the 940

ok so if I am using this mother bourd, http://www.newegg.com/app/viewProduc...factory=BROWSE



and this processor, http://www.newegg.com/app/viewProduc...factory=BROWSE



I can use this ram, http://www.newegg.com/app/viewProduc...factory=BROWSE



sorry for all the questions I just don't want to order all this stuff to build a pc and have it not work.



Thank you very much for your help!

It should work just fine
