Advanced Memory Technology

ECC Registered Architecture

Error Correcting Code (ECC) technology provides single-bit error correction and multi-bit error detection capabilities, ensuring data integrity and system reliability. The registered design incorporates address and command registers that reduce electrical load on the memory controller, enabling support for higher memory capacities and improved signal integrity across large memory arrays. This combination makes ECC Registered memory ideal for mission-critical applications where data corruption cannot be tolerated.

Dual Rank X4 Configuration Benefits

The dual rank configuration effectively doubles the memory access parallelism compared to single-rank modules, while the x4 organization with four internal banks provides enhanced memory efficiency. This architecture reduces contention between memory requests and improves overall system throughput, particularly important for multi-threaded applications and virtualization environments running multiple simultaneous workloads.

288-pin RDIMM Form Factor

The 288-pin Registered DIMM (RDIMM) form factor follows JEDEC standards while incorporating Dell-specific validation parameters. The physical design ensures proper mechanical compatibility with VxRail memory slots and includes notches that prevent incorrect installation. The robust construction maintains signal integrity at high speeds through careful impedance control and signal routing.

VxRail HCI System Integration

Optimized for Hyper-Converged Infrastructure

This memory module is specifically engineered and validated for Dell VxRail hyper-converged infrastructure systems.

The module supports extended performance profiles that go beyond standard JEDEC specifications. These Dell-optimized timing parameters extract maximum performance while maintaining system stability. The memory includes serial presence detect (SPD) data that automatically configures the system for optimal operation without manual intervention.

Virtualization Performance Impact

In virtualized environments, memory speed and latency directly impact VM density and application performance. The 3200MHz operating frequency reduces memory access latency, improving response times for memory-intensive applications. The large 64GB capacity enables consolidation of more virtual machines per host while maintaining adequate memory headroom for burst workloads.

Power Management Features

DDR4 technology introduces several power-saving innovations including data bus inversion and command/address parity. These features, combined with the lower 1.2V operating voltage, contribute to reduced power consumption compared to previous generations. The memory supports various low-power states that automatically activate during periods of reduced memory activity.
