Dell AC049361 32GB DDR5 Memory Module

DDR5 Technology

The Dell AC049361 represents the cutting edge of DDR5 SDRAM technology, delivering significant performance improvements over previous DDR4 generations. This 32GB module operates at PC5-38400 classification with a data rate of 4800MT/s (million transfers per second), providing substantial bandwidth enhancement for memory-intensive applications and workloads.

Memory Density

32GB Capacity

This 32GB module provides substantial memory headroom for demanding computing environments. The high-density design utilizes advanced semiconductor manufacturing processes to pack 32 gigabytes of storage onto a single 288-pin DIMM, making it ideal for workstations, servers, and high-performance computing systems requiring large memory capacities.

Unbuffered Architecture Benefits

As an Unbuffered DIMM (UDIMM), the Dell AC049361 operates without buffer chips between the memory controller and DRAM chips, resulting in lower latency compared to registered or load-reduced modules. This makes it particularly suitable for desktop workstations and entry-level servers where minimal memory access latency is critical for application responsiveness.

Performance Characteristics

Speed and Bandwidth Specifications

Operating at 4800 million transfers per second, this DDR5 module delivers peak theoretical bandwidth of 38.4 GB/s in a single module configuration. The increased data rate represents approximately a 50% improvement over standard DDR4-3200 modules, enabling faster data access and improved system responsiveness across all computing tasks.

PC5-38400 Classification

The PC5-38400 designation indicates compliance with JEDEC standards for DDR5 modules operating at 4800MT/s. This classification ensures compatibility and performance consistency across different systems and platforms, providing reliable operation in qualified Dell systems and compatible third-party platforms.

CAS Latency Optimization

The Dell AC049361 features optimized CAS latency timings that balance high-speed operation with responsive memory access. While specific timing parameters may vary based on system configuration and BIOS settings, this module is engineered to deliver the ideal latency-to-speed ratio for professional workloads and general computing tasks.

Efficiency

DDR5 technology introduces improvements in command rate efficiency, allowing for more streamlined memory operations. The enhanced command bus and separate address/command channels contribute to reduced command conflicts and improved overall memory controller efficiency compared to previous DDR generations.

Physical Specifications

Module Form Factor

The module utilizes the standard 288-pin Dual In-line Memory Module (DIMM) form factor specified by JEDEC for DDR5 memory. The pin configuration is specifically designed to prevent insertion into incompatible DDR4 slots, ensuring proper installation and system protection. The physical dimensions comply with industry standards for height, width, and PCB thickness.

UDIMM Physical Characteristics

As an Unbuffered DIMM, this module features a single notched design that aligns with the keying in compatible memory slots. The standard height of 1.23 inches (31.25mm) ensures compatibility with most system configurations, including those with large CPU coolers and complex thermal solutions.

Key Specifications

On-DIMM Power Management IC

This DDR5 module includes an integrated Power Management Integrated Circuit (PMIC) that distributes the 1.1V VDD power supply to the appropriate voltage levels required by different components on the module. This on-module power management improves power delivery efficiency and reduces motherboard design complexity while providing more stable voltage regulation.

Power Efficiency

Operating at a nominal voltage of 1.1V, the Dell AC049361 delivers improved power efficiency compared to DDR4 modules that typically operate at 1.2V. The reduced operating voltage contributes to lower power consumption and reduced heat generation while maintaining high-performance operation, making it suitable for energy-conscious computing environments.

Signal Integrity

DDR5 technology introduces Decision Feedback Equalization to the memory interface, enabling improved signal integrity at high data rates. This advanced signal processing technique helps compensate for channel losses and inter-symbol interference, allowing reliable operation at 4800MT/s and beyond.

On-Die ECC Implementation

The module incorporates on-die Error Correction Code functionality that corrects bit errors within the DRAM chips themselves. This additional layer of data protection enhances reliability by addressing errors that occur during cell refresh operations and internal data transfers, complementing traditional system-level ECC when available.

Compatibility and System Requirements

Dell System Integration

The Dell AC049361 is engineered specifically for compatibility with Dell workstation and server platforms that support DDR5 memory technology. The module undergoes rigorous testing and validation within Dell's ecosystem to ensure seamless operation, optimal performance, and reliable service life in supported configurations.

Industry Standard Compatibility

While optimized for Dell systems, this UDIMM module adheres to JEDEC standards for DDR5 memory, providing compatibility with other manufacturer's platforms that support unbuffered DDR5 memory at 4800MT/s. Users should verify specific system compatibility and BIOS requirements before installation in non-Dell systems.

Application Scenarios
