ECC Registered DDR3 for Servers

This kit provides 32GB of DDR3 1866 ECC registered memory in a matched pair of 16GB modules. It is built for workstations, servers and NAS systems that require registered DIMMs with error correction. Standard desktop platforms cannot use this memory.

Dual-channel 240-pin kit

The two modules operate together in dual-channel mode on boards with 240-pin DDR3 slots that support registered ECC. Each stick runs at 1.5V with CL13 timing and a 2Rx4 organisation. No heat spreaders are fitted, so clearance is minimal.

For registered-ECC platforms only

Buyers whose systems accept DDR3 registered ECC RDIMMs can use this kit to expand capacity. It will not work in computers that need unbuffered non-ECC memory or in platforms that use a different DDR generation.

Questions about this item

Will the 1866 MHz speed hold under sustained server workloads?

The modules run at DDR3 1866 (PC3-14900) with CL13 latency at 1.5 V, matching JEDEC specifications for continuous operation.

How much heat do these registered DIMMs produce during all-day use?

The kit has no heat spreader and operates at the standard 1.5 V, so thermal output stays within normal DDR3 registered DIMM limits.

What motherboard features are required to use this ECC registered kit?

The system must provide 240-pin DDR3 slots that support ECC registered (RDIMM) memory; standard desktop boards that only accept unbuffered DIMMs will not work.
