64GB DDR4 ECC RDIMM Kit

This 64GB kit contains four 16GB DDR4 3200 modules built as ECC Registered DIMMs for servers and workstations. Each module runs at 1.2V with CL22 latency and uses a dual-rank x8 organisation. The 288-pin form factor fits only systems that support registered ECC memory.

Upgrade from lower-capacity or slower DDR4 RDIMMs

The jump is worth it when your workload needs more simultaneous threads or larger datasets than your current memory allows. Adding this quad-channel kit increases total bandwidth and reduces swapping on compatible platforms. It does not fit desktop or laptop boards that require unbuffered non-ECC modules.

Straightforward installation with channel awareness

Install all four modules following the motherboard manual for quad-channel population order. The registered design adds electrical load, so verify the CPU memory controller supports the full population. Mismatched ranks or mixing with unbuffered DIMMs will prevent boot.

Spurningar um þessa vöru

Will these 288-pin DDR4 RDIMMs fit my server's DIMM slots?

These are standard 288-pin DDR4 RDIMMs. They fit only server or workstation boards that support DDR4 registered ECC memory; they will not work in desktop or laptop systems.

What is the correct way to populate the four modules for quad-channel operation?

Install one module per channel following the motherboard's slot-colour guide; the common mistake is placing two modules in the same channel while leaving another channel empty.

How can I tell if one of the 16 GB sticks has failed and needs replacing?

The server's BIOS or OS will log corrected or uncorrected ECC errors tied to a specific DIMM slot; swap the suspect module to confirm the fault follows the stick.
