Registered RAM?

[Henry Rollins II]

Hi all

What is reg. DIMMs? How can they have a cas latency of 2,3? Do they increase or decrease system stability and/or speed? Is there a good faq about this somewhere, I couldn´t find anything.

regards,
Henry

What does "registered" SDRAM mean?

Solution:

The term "registered" refers to how the memory module processes signals. Registered modules contain a register that delays all information transferred to the module by one clock cycle. This type of memory is primarily used in servers and was designed for modules with 32 or more chips on them to help ensure that data is properly handled.

While most PCs will only accept unbuffered SDRAM, there are some that accept registered SDRAM. Keep in mind that when you install registered SDRAM, all of the modules installed in your PC must be registered because unbuffered and registered modules are not interchangeable.

They are slightly slower than unbuffered but more stable.

but can a board that says " supports up to 3gb registered DDR SDRAM" use ram that isnt registered sdram?
