About this item

HP/SK Hynix HMAA8GL7CPR4N-VK is a 64GB DDR4 2666MHz ECC Load-Reduced DIMM (LRDIMM) server memory module built for enterprise and data center environments. Featuring a 4Rx4 quad-rank configuration, on-module data buffers, and PC4-2666V-L performance at 1.2V, it delivers maximum memory density per channel with strong stability and reliable error correction for mission-critical workloads.

Pulled from working systems, tested and functional.

Key Features

  • Model: HP/SK Hynix HMAA8GL7CPR4N-VK — 64GB DDR4 2666MHz (PC4-21300) ECC LRDIMM
  • Load-Reduced Architecture: A register and on-module data buffers isolate the DRAM ranks from the memory bus, reducing electrical load so platforms can run higher-capacity, higher-rank modules across more slots per channel than registered DIMMs allow.
  • High Density Support: The 4Rx4 quad-rank configuration places four ranks of x4 DRAM on a single 288-pin module, delivering 64GB per slot for high-density enterprise deployments.
  • Standard Voltage Operation: Runs at 1.2V with CL19 timings at 2666MHz for balanced performance and power draw in fully populated server platforms.
  • Data Integrity: Integrated ECC (Error-Correcting Code) functionality helps detect and correct memory errors in real time, ensuring improved system reliability and uptime for mission-critical workloads in data center environments.
  • Enterprise-Grade Design: Engineered specifically for server and workstation platforms requiring dependable high-capacity memory. Not compatible with consumer desktops or laptops due to LRDIMM architecture and ECC requirements.
  • Dual HP/SK Hynix Label: Carries the HP part label but works in any system supporting a standard 288-pin DDR4 LRDIMM interface — not limited to HP systems.
  • Compatibility: Supports enterprise platforms using standard 288-pin DDR4 LRDIMM memory slots that specifically support 64GB quad-rank modules. Operating speed depends on your CPU and DIMM population and may run below 2666MHz when multiple modules share a channel — verify against your platform's memory QVL and population rules.
  • Note: You cannot mix LRDIMMs with RDIMMs or UDIMMs in the same system — ensure all installed modules are of the same type.

We test every memory before you do.

Every RAM module Server Part Deals sells passes an internal 4-stage testing protocol before it ships. While many resellers stop at a basic visual inspection, we validate identification data, memory capacity, performance, and stability under sustained load. Each module is checked to confirm that it meets or exceeds its rated specifications.

Stage 1: Physical Inspection

  • Connector and contact inspection
  • PCB damage and corrosion check
  • Component and solder integrity
  • Label and part-number verification

Stage 2: Module Validation

  • Capacity and speed validation
  • ECC and memory-type confirmation
  • Rank and configuration check

Stage 3: Performance Testing

  • Multi-round read/write cycles
  • Bandwidth and latency validation
  • Performance benchmarking
  • Load and stress simulation

Stage 4: Memory Integrity Testing

  • Full-address memory scan
  • Bit-error detection
  • ECC error monitoring
  • Final inventory verification
