Multi-Link AXIOM 64GB DDR4-2666 ECC LRDIMM video accessory

SKU CH-76DK-0QZQ6

High-capacity 64 GB DDR4 server memory module with ECC error checking and 2666 MHz speed

  • Product typeOffice Products
  • 64 GB capacity supports large memory workloads
  • DDR4-2666 speed delivers 21300 MT/s data rate
  • ECC with CL19 latency protects data integrity
  • 288-pin LRDIMM form factor fits compatible Lenovo ThinkSystem SR550 servers
  • RoHS certified and environmentally friendly design

Purpose-built server memory

This 64 GB DDR4 LRDIMM is designed for the Lenovo ThinkSystem SR550 server. It targets administrators who need high-capacity, error-correcting modules for virtualisation or database workloads.

Speed and latency limits

The module operates at 2666 MHz with a CAS latency of CL19 and a voltage of 1.20 V. The PC4-21300 standard defines the maximum throughput; workloads requiring higher frequencies or lower latencies will not be supported by this part.

Installation notes

The 288-pin LRDIMM form factor fits the SR550 memory slots directly. Builders must populate compatible channels in the correct order; mixing this module with standard RDIMMs or non-ECC memory will prevent the system from booting.

Questions about this item

Should I choose the 64 GB LRDIMM or a smaller RDIMM for my ThinkSystem SR550?

The 64 GB LRDIMM reduces electrical load on the memory bus, allowing the SR550 to reach higher total capacity than standard RDIMMs.

What does the 2666 MHz rating deliver inside a ThinkSystem SR550?

The module runs at 2666 MHz with CL19 latency, providing DDR4-2666/PC4-21300 bandwidth for the SR550 memory controller.

How does the 288-pin DDR4 LRDIMM interface limit performance in the SR550?

The 288-pin DDR4 interface caps speed at 2666 MHz and 1.20 V, matching the SR550 memory controller specification.
