QNAP RAM-64GDR4ECK0-RD-3200 64GB DDR4-3200 ECC RDIMM

QNAP RAM-64GDR4ECK0-RD-3200 – Enterprise ZFS NAS Memory Module

Overview :

The QNAP RAM-64GDR4ECK0-RD-3200 is a high-capacity 64GB DDR4 SDRAM module designed for enterprise-grade NAS infrastructure. As a Registered DIMM (RDIMM) equipped with Error-Correcting Code (ECC), it is engineered for high-density server environments that require absolute stability. The ECC technology proactively detects and repairs single-bit errors, ensuring that mission-critical data remains uncorrupted during intensive, long-term operations.

This Enterprise ZFS NAS memory module operates at 3200 MT/s, providing the high-speed throughput necessary for data-heavy applications. It is specifically optimized for ZFS-based systems where large amounts of RAM are used for ARC (Adaptive Replacement Cache), inline deduplication, and real-time compression. Increasing memory capacity with this 64GB module allows for higher virtual machine density and smoother performance in multi-tenant environments.

The module is intended for use in QNAP's high-end rackmount series powered by Intel Xeon or AMD EPYC processors. Due to its Registered (RDIMM) architecture, it facilitates better signal integrity when multiple modules are installed in a single system. This RAM should not be used in entry-level or mid-range NAS units that support only Unbuffered (UDIMM) memory, as the two types are electrically incompatible.

Key Features :

• 64GB high-density capacity supports extensive virtualization loads.

• 3200 MHz frequency maximizes data transfer rates for ZFS caching.

• ECC (Error-Correcting Code) prevents data corruption and crashes.

• Registered DIMM design ensures stability in multi-slot configurations.

• Fully validated for QNAP QuTS hero and QES enterprise platforms.
