Server DDR4 upgrade kit

This 64 GB kit contains four 16 GB registered DIMMs built for DDR4 servers and workstations. Each module runs at 2933 MHz with CL21 latency at 1.2 V and provides ECC error correction. The single-rank x4 layout supports quad-channel operation on compatible platforms.

Registered ECC constraints

Registered DIMMs with ECC only function in systems designed for DDR4 RDIMM memory; they will not work in standard desktop or laptop motherboards. The 288-pin form factor and registered buffer require matching chipset support and correct channel population rules.

Replaces non-ECC or lower-capacity RDIMMs

The jump is worthwhile when moving from unbuffered memory or smaller registered kits to gain error correction and higher total capacity for virtualization or database workloads. Systems limited to slower DDR4 speeds or fewer channels will not use the full 2933 MHz bandwidth.

Questions about this item

Should I choose the 4 x 16 GB kit or a different capacity for my server?

This kit provides 64 GB total across four 16 GB modules, designed for quad-channel server and workstation platforms that support DDR4 registered ECC memory.

What does the 2933 MHz rating mean once the modules are installed?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency at 1.2 V, delivering the rated throughput when the platform enables the matching memory controller speed.

How does the DDR4 288-pin RDIMM interface limit performance in practice?

The registered 288-pin DDR4 interface caps operation to the platform's maximum supported DDR4 speed and requires a server or workstation motherboard that accepts registered ECC DIMMs.
