Registered RAM

[SuperVisor]

When descibing RAM. What does 'registered' mean? See here. Do they work only on certain types of motherboards/processors?

 

[Evadman]

Registered ram has an internal "register" that delays the Memory access by 1 CPU cycle. It is there as a sort of buffer, so the right and correct data is read/written.

This might be a little more appropriate in General Hardware.

To answer the question though, Registered RAM contains a register that delays data transferred to the module by one clock cycle, it's done to help ensure the reliability and accuracy of data transferred.

Is this compatible ONLY with motherboards requiring 'Registered' ram or all motherboeards??

 

[John]

Not all motherboards support "registered" and/or "ecc" memory.

Is there a way to tell which motherboards support 'Registered' ram or is it trial and error. If I shop for ram, do ask I for 'Registered' or not??
