64GB DDR4 ECC RDIMM for Servers

This 64GB registered DIMM uses DDR4 2666 technology with ECC and a quad-rank 3DS layout. It is built for servers and workstations that require registered memory and cannot be used in desktop or laptop computers. The module delivers 64GB of capacity in a single 288-pin slot.

DDR4 2666 Registered Interface Limits

The DDR4 2666 standard tops out at 2666 MT/s with a CL19 latency at 1.20V. Registered signalling adds one cycle of address/command buffering, which stabilises heavy loads but prevents use in unbuffered consumer platforms. Quad-rank 3DS stacking increases electrical load per slot, so maximum supported module count depends on the platform's memory controller.

64GB Capacity and Headroom

A single 64GB module suits memory-hungry virtualisation hosts, in-memory databases and large dataset analytics. Workloads that exceed 64GB per channel will need additional populated slots, limited by the server's qualified vendor list and rank-per-channel rules. The 1.2V operation keeps power draw within standard DDR4 limits for dense configurations.

Questions sur cet article

Should I pick a 64 GB module or combine smaller sticks to reach the same total?

A single 64 GB module leaves more DIMM slots free for future expansion, while multiple smaller sticks can enable more memory channels if your platform supports them.

What does the 2666 MHz rating actually deliver inside a server?

The module runs at DDR4 2666 with CL19 latency, giving a peak bandwidth of PC4-21300 when the memory controller is configured for that speed.

How does the 288-pin registered ECC interface limit what I can install?

The 288-pin RDIMM form factor only fits server and workstation boards that accept DDR4 ECC registered memory; it will not work in desktop or laptop slots.
