Server DDR4 ECC RDIMM kit

This 64 GB kit contains four 16 GB DDR4 2400 MHz modules built as registered DIMMs with ECC and a dual-rank x4 organisation. It is intended for servers and workstations that require error-correcting registered memory.

Quad-channel registered memory

The four modules populate a quad-channel configuration on platforms that support DDR4 RDIMM slots with 288 pins. Registered buffering reduces electrical load on the memory controller, and ECC protects data integrity in multi-tasking workloads.

For ECC server platforms only

Buyers who need memory for standard desktop or laptop systems cannot use these modules because they require registered ECC support. Builders whose platforms accept only unbuffered non-ECC DDR4 should select a different kit.

Questions about this item

Does the CL17 latency at DDR4 2400 become the bottleneck during sustained workloads?

The kit runs at DDR4 2400 with CL17 timing, so the memory controller waits 17 cycles per access; under continuous load that latency is the first limit you hit.

How much heat and power do the four 16 GB registered modules produce when running all day?

Each module operates at the standard DDR4 voltage of 1.2 V; registered DIMMs draw slightly more power than unbuffered types, so expect modest but steady heat output across the 288-pin sticks.

What must the system already have to use this quad-channel ECC RDIMM kit?

The motherboard must support DDR4 registered ECC memory, provide four 288-pin DIMM slots wired for quad-channel operation, and accept dual-rank x4 modules.
