SAMSUNG 64GB DDR4-2666 LRDIMM CL19 1.20V M386A8K40BM2-CTD

SKU CH-YQH2-TWH9Q

64 GB DDR4-2666 load-reduced DIMM with CL19 latency and 1.20 V operation for high-density server memory

  • 64 GB capacity supports large virtualised workloads
  • Load-reduced design lowers electrical load on the memory bus
  • DDR4-2666 speed delivers 21300 MT/s data rate
  • Low 1.20 V operation reduces server power draw

64GB DDR4-2666 LRDIMM Module

This Samsung LRDIMM provides 64GB of DDR4 server memory at 2666 MT/s. It uses a load-reduced 4DRx4 organisation with CL19 latency and runs at 1.20V across 288 pins. The PC4-21300 rating confirms the peak transfer rate for demanding multi-socket platforms.

Capacity and form factor fit high-density servers

The 64GB density suits hosts that need maximum RAM per slot in a standard 288-pin DDR4 socket. Buyers who want more storage or a different memory technology should look at other product categories. Systems requiring unbuffered UDIMMs or lower-capacity registered DIMMs will not accept this module.

Highlights

  • 64 GB capacity supports large virtualised workloads
  • Load-reduced design lowers electrical load on the memory bus
  • DDR4-2666 speed delivers 21300 MT/s data rate
  • Low 1.20 V operation reduces server power draw

Questions about this item

Should I pick the 64 GB LRDIMM or a smaller RDIMM for my server?

Choose the 64 GB LRDIMM when you need maximum capacity per slot; its load-reduced design lets the memory controller drive more ranks than a standard RDIMM.

What does the 2666 MT/s rating deliver in a live system?

The module runs at 2666 MT/s with CL19 latency, providing 21300 MB/s peak bandwidth per channel when the platform supports DDR4-2666.
