16 GB DDR3 ECC Registered RDIMM

This 16 GB DDR3 module runs at 1066 MT/s with CL7 latency and a 1.5 V operating voltage. It uses a 240-pin RDIMM form factor and a 2Rx4 rank configuration. The module includes ECC and registered buffering for data integrity in multi-socket environments. It is built for select workstations and servers that require registered memory.

Replaces lower-capacity or non-ECC DDR3 DIMMs

The jump is worth it when a system supports registered ECC memory and needs 16 GB per slot to reach higher total capacity. It will not work in standard desktop platforms that accept only unbuffered modules. Mixing with unbuffered DIMMs is not supported and will prevent boot. Buyers who need unbuffered memory for a consumer motherboard cannot use this module.

Installs into a 240-pin DDR3 RDIMM slot

Alignment keys on the module and socket prevent incorrect insertion. The system must explicitly support registered ECC DDR3 at 1066 MT/s; otherwise the module will not be recognised. A common issue is installing this module in a desktop board that only accepts unbuffered memory. Another is mixing registered and unbuffered DIMMs in the same platform.

Perguntas sobre este artigo

Will this 16 GB DDR3 module fit a 240-pin registered DIMM slot?

Yes, it is a 240-pin DDR3 ECC RDIMM that requires a registered server or workstation slot; it will not work in unbuffered desktop boards.

What is the correct way to seat the 1.5 V RDIMM so the ECC register initialises?

Align the notch with the key, press straight down until both side clips click, and ensure the system BIOS is set to registered mode before boot.

When should the 2Rx4 1066 MHz module be replaced or tested?

Run a full memory diagnostic at install and after any unexplained crashes; replace if errors appear or when the platform is upgraded beyond DDR3.
