Registered vs Unbuffered SDRAM DIMMs

[bmsabcd]

Anyone know the difference between Registered vs. Unbuffered SDRAM DIMMs?

[Bleeding Edge]

"A buffer is a device used on EDO or Fast Page Mode modules. A register is used on SDRAM modules." They both do the same thing. "Registers and buffers 're-drive' or 'amplify' signals as they enter the memory module."

So, on an unbuffered sdram dimms the signals aren't "amplified", where as, the registered modules are.

Registered CL2 ECC sdram modules are great for highend workstations or servers. If your comfortable paying premium prices, get them.

Forgot about that link. Thanks Roy.

By the way, mind asking 8 or Elf to make an appearence over at www.sysopt.com/forum/Forum4/HTML/000591.html (http://www.sysopt.com/forum/Forum4/HTML/000591.html) I seem to be misunderstood. Am I doing something wrong there? Things may need smoothing out. Your input is much valued.
