  • 5V operation meets JEDEC standard for compatibility
  • 240-pin RDIMM form factor fits select workstations and servers

Server ECC RDIMM Kit

This 64GB kit provides eight 8GB DDR3 registered DIMMs rated at 1866 MT/s with CL13 latency. It is built for workstations, servers, NAS appliances and routers that require ECC registered memory. The modules operate at 1.5V and conform to JEDEC PC3-14900 specifications. No heat spreaders are fitted.

Suited for ECC platforms only

The registered design and ECC function make this kit suitable for multi-socket servers and error-correcting workloads. It will not work in standard desktop boards that accept only unbuffered non-ECC memory. Builders needing unbuffered DIMMs or higher DDR generations should look elsewhere.

Capacity and headroom

Eight modules populate eight slots for a total of 64GB, giving ample headroom for virtualisation, large databases or memory-intensive file services. The dual-channel kit layout assumes a platform that can address all ranks at the rated speed. Systems limited to fewer slots or lower memory ceilings will not use the full capacity.

Questions about this item

What motherboard slot type is required for the 240-pin DDR3 RDIMMs in this kit?

The modules use the standard 240-pin DDR3 DIMM form factor and require a motherboard with registered DIMM slots that support ECC registered memory.

Can I add these CL13 1.5V registered modules to a system that already has unbuffered ECC DDR3 installed?

No, registered and unbuffered ECC memory cannot be mixed; the motherboard must support registered DIMMs exclusively for this kit to function.

How can I verify the full 64GB kit is running at DDR3 1866 with CL13 timings after installation?

Check the BIOS memory information or use a system utility such as CPU-Z to confirm the speed reads 1866 MT/s, CAS latency 13 and all eight 8GB modules are detected.
