8GB DDR3-1333 ECC Registered Module

This 8GB Samsung module runs at DDR3 1333 (PC3 10600) with CL9 latency and a registered signal. It is built for servers and workstations that require error-correcting code memory and registered DIMMs. The dual-rank 2Rx4 organisation suits multi-socket platforms. It operates at the standard DDR3 voltage of 1.50V.

Suits ECC-registered platforms.

It fits systems that specifically accept 240-pin DDR3 RDIMMs with ECC enabled in the BIOS. Builders using desktop motherboards that only support unbuffered non-ECC UDIMMs cannot use this module. Buyers who need low-profile unbuffered memory for standard PCs should look elsewhere.

Registered ECC with 2Rx4 organisation

The registered buffer and on-die ECC are the decisive specifications; the memory controller must support both. If the platform requires unbuffered memory or cannot enable ECC, this module will not function. The 2Rx4 rank structure also affects maximum population rules per channel.

Questions about this item

What motherboard slot and voltage must my system provide for this 240-pin DDR3 registered DIMM?

The module fits a 240-pin DDR3 DIMM slot and operates at 1.50 V as a registered ECC part.

Will this 1333 MHz CL9 module run reliably if I keep slower DDR3 DIMMs in the other channels?

Yes, the memory controller will down-clock all modules to the lowest common speed and latency, so slower DDR3 DIMMs can remain installed.

How can I confirm the module is recognised as 8 GB ECC registered memory after installation?

Check the BIOS memory summary or run a tool such as dmidecode; it should report 8 GB, DDR3-1333, ECC registered, dual-rank 2Rx4.
