SK hynix HMAA8GL7AMR4N-VK 64 GB DDR4-2666 LRDIMM server RAM

SKU CH-6PJH-KN1MR MPN HMAA8GL7AMR4N-VK

64 GB DDR4-2666 LRDIMM with ECC and registered signal processing for high-capacity server memory

  • Type288-Pin DDR4 SDRAM
  • CAS LatencyCL19
  • 64 GB capacity provides room for complex applications
  • 2666 MHz speed supports smooth system performance
  • CL19 latency enables quick data access and retrieval
  • ECC registered design ensures data integrity for servers
  • LRDIMM form factor reduces electrical load on memory controller

64 GB LRDIMM for DDR4 servers

This 64 GB LRDIMM module is built for DDR4 server platforms that need high memory capacity per slot. It uses load-reduced technology to ease the electrical load on the memory controller. The registered design adds signal buffering for stable operation in multi-module configurations. It targets administrators scaling memory in compatible DDR4 systems.

2666 MHz DDR4 bandwidth limit

The module runs at 2666 MHz with CL19 latency under the DDR4 standard. Bandwidth is capped by the DDR4-2666 interface, so total throughput cannot exceed that ceiling. ECC protection is included for data integrity in critical workloads. Systems locked to lower memory speeds will downclock the module automatically.

288-pin LRDIMM build and fit

The 288-pin LRDIMM form factor fits standard DDR4 server DIMM slots with the correct keying. Registered signalling and the load-reduced architecture help maintain signal quality across populated channels. The module operates at 1.20 V, matching the DDR4 baseline voltage. Buyers who need unbuffered UDIMMs or a different DDR generation cannot use this module.

Otázky k tomuto produktu

Should I choose the 64 GB DDR4-2666 LRDIMM or a lower-capacity RDIMM?

The 64 GB LRDIMM uses a load-reduced design that lessens electrical load on the memory controller, allowing this high density per module where standard RDIMMs cannot reach the same capacity.

What does the 2666 MHz rating deliver in an actual server?

The module runs at up to 2666 MHz with CL19 latency, providing registered ECC signal processing for data integrity in multi-socket workloads.

How does the DDR4-2666 interface limit performance in practice?

The 288-pin DDR4 interface operates at 1.20 V and 2666 MHz, with the registered buffer and LRDIMM architecture managing signal integrity at this speed.
