Server Memory for ECC Registered Workloads

This 16GB DDR3 module operates at 1333MHz with CL9 latency and 1.35V voltage. It uses a 240-pin form factor and includes ECC registered technology for data integrity. The unit is suited for servers requiring registered memory architecture. It is not for systems that only accept unbuffered non-ECC modules.

Sustained Load Behaviour with Registered Buffer

The registered buffer reduces electrical load on the memory controller during continuous operation. ECC circuitry detects and corrects single-bit errors without halting the system. CL9 timing and 1.35V voltage maintain stable throughput under prolonged demand. The module is not for platforms that cannot address registered DIMMs.

Installation Notes for 240-Pin DDR3 Slots

Align the notch on the 240-pin edge connector with the motherboard key before applying even pressure until the retention clips engage. Verify the server BIOS recognises the full 16GB capacity and registered mode at POST. The unit is not for boards limited to unbuffered memory or a different DDR generation.

Questions about this item

How much power does the 16 GB DDR3 1333 module draw at its 1.35 V rating when running continuously?

At 1.35 V the 16 GB DDR3 1333 registered ECC DIMM runs cooler and draws less power than standard 1.5 V DDR3, helping keep server chassis temperatures lower during all-day workloads.

What motherboard slot and chipset support are required for this 240-pin registered ECC DDR3 1333 DIMM to function?

You need a server-class motherboard with 240-pin DDR3 slots that explicitly supports registered ECC memory and PC3-10600 speed; consumer desktop boards typically cannot use registered modules.

Can this CL9 1.35 V registered ECC DDR3 1333 stick share a channel with older 1.5 V unbuffered DDR3 DIMMs?

No — registered ECC and unbuffered non-ECC DIMMs use different signalling and must not be mixed on the same channel or the system will fail to post.
