AA192163 Dell 32GB Memory 2Rx4 ECC Module PC4-23400

Dell 32GB 2Rx4 Memory Overview

The Dell AA192163 32GB 2Rx4 2933MHz PC4-23400 CL21 ECC Registered Dual Rank X4 1.2V DDR4 SDRAM 288-Pin RDIMM Genuine Memory Module occupies a focused space in the enterprise memory category where reliability, error correction, and predictable performance matter more than headline clock speeds alone. This memory module is designed for use in servers and high-end workstations that require ECC protection and the stability of registered (RDIMM) buffering. It represents a mainstream, capacity-optimized choice for organizations that balance memory capacity per socket with the demand for sustained throughput across multi-socket platforms. The module’s specification—32GB, dual-rank, x4 organization, DDR4-2933, CL21 timing and ECC registered topology—tells the story of a part engineered to deliver data integrity and compatibility with enterprise BIOS and memory controllers while operating at a low-voltage 1.2V standard to reduce power draw and heat under continuous operation.

Technical Identity

The full designation—Dell AA192163 32GB 2Rx4 2933MHz PC4-23400 CL21 ECC Registered Dual Rank X4 1.2V DDR4 SDRAM 288-Pin RDIMM Genuine Memory Module—serves both marketing clarity and technical precision. Each segment of the name maps to critical characteristics: the manufacturer identifier Dell the capacity marker (32GB) indicates the module’s usable storage for system memory; the rank and chip organization (2Rx4) explain how the memory chips are grouped and how the module presents itself to the memory controller; the speed rating (2933MHz and PC4-23400) relates to peak theoretical bandwidth; CL21 indicates the column address strobe latency in clock cycles; ECC Registered indicates the module’s capability to perform on-the-fly single-bit correction with registered buffering for signal integrity; the 288-pin RDIMM form factor confirms compatibility with standard DDR4 server memory sockets; and 1.2V denotes adherence to DDR4 standard voltage to optimize power consumption and thermal envelope.

Core Characteristics

Operating at the DDR4 baseline voltage of 1.2 volts, the Dell AA192163 module benefits from modern low-power design practices. The 288-pin RDIMM layout is the industry-standard physical interface for DDR4 server memory, ensuring that the module fits standard server DIMM slots while supporting the electrical and timing specifications enforced by server motherboards and memory controllers. The 2933MHz data rate corresponds to a PC4-23400 classification, which quantifies the module’s data throughput in megabytes per second under ideal operating conditions. The CL21 timing offers a balanced latency profile for a mid-frequency enterprise module; while not the lowest possible latency for DDR4, the timing is chosen to maintain signal margin and compatibility across server platforms under ECC and registered operation.

Memory Architecture

Several architectural choices in this module carry direct implications for performance, capacity scaling, and compatibility. The “2R” in 2Rx4 signifies dual-rank operation. A dual-rank module behaves like two smaller memory modules on a single DIMM, which can increase effective memory parallelism and density but also has implications for memory channel loading and the maximum number of modules supported per channel. The “x4” chip organization denotes that each memory chip on the module has a 4-bit wide data bus. This organization typically yields a larger number of chips on the module compared to x8 or x16 organizations at the same capacity, and it aligns with ECC schemes and certain server memory controller preferences. In practice, dual-rank x4 RDIMMs like the Dell AA192163 are commonly selected when a balance of 32GB capacity and broad compatibility with server ECC implementations is required.

ECC Registered

Error-Correcting Code (ECC) is a defining attribute for server-grade memory because it enables detection and correction of single-bit errors and detection of multi-bit errors, significantly improving the reliability of systems that process critical data 24/7. Registered memory (RDIMM) introduces a register between the memory controller and the DRAM chips to buffer command and address signals, improving signal integrity especially in systems populated with many DIMMs. When combined, ECC Registered modules provide a stable, reliable memory subsystem for database servers, virtualization hosts, scientific compute nodes, and storage controllers where a single undetected memory error could have outsized consequences. The Dell AA192163 module’s ECC Registered design thus prioritizes resilience over the minimal latency advantages sometimes favored in desktop memory.

Compatibility

Compatibility is a crucial aspect of server memory selection. RDIMM modules are intended for systems that explicitly support registered ECC memory. While many enterprise-grade servers, especially those in the Dell ecosystem, accept RDIMMs, it is essential to verify motherboard or system vendor documentation before purchase. The module’s 288-pin physical configuration aligns with the DDR4 standard, but electrical compatibility—for instance memory controller support for 2933MHz speeds, accepted rank and chip organizations, and maximum per-channel population—must be confirmed against the target platform’s memory compatibility list or vendor specifications. The Dell AA192163 module’s designation as a “genuine memory module” emphasizes its verified manufacturing origin and the likelihood of firmware-level SPD (Serial Presence Detect) settings that help system BIOS configure memory timings and voltages automatically.

Use Cases

This category of memory is particularly well-suited to several classes of workloads. Virtualized environments and hypervisors that host multiple guest VMs benefit from the large memory capacity and ECC protection, which help maintain guest stability and reduce the risk of soft errors that could compromise long-running services. Database servers, both transactional and analytical, gain from the increased working set size made possible by 32GB modules, allowing larger in-memory caches, buffer pools, and reduced disk I/O. Compute clusters running scientific or simulation workloads will appreciate ECC’s error mitigation, while storage controllers and file servers relying on memory for caching or metadata operations require the determinism and correction capabilities that ECC RDIMMs provide. High-availability environments, where error prevention directly translates to uptime, are prime candidates for Dell AA192163 modules.

Performance

To extract the best stable performance from modules like the Dell AA192163, follow platform-specific guidance on memory population rules, channel balancing, and rank limitations. Populate memory channels in accordance with the server or motherboard manual to ensure symmetric channel loading and to enable optimal interleaving of memory addresses. When increasing memory capacity, prefer matched pairs or kits tested together to minimize SPD mismatches. If your server supports multiple frequency steps, use the highest JEDEC-defined frequency supported by all DIMMs in the system unless you have validated manual settings. Monitor error logs and system telemetry after upgrades to confirm that the addition of new modules does not introduce ECC error counts or signal-related warnings. Because RDIMMs add a register stage, confirm the maximum supported number of RDIMMs per channel for your CPU/motherboard combination before densely populating all slots.

Reliability

Enterprise memory modules like the Dell AA192163 are designed for continuous operation and long lifecycle service. They are subjected to tighter quality controls and screening than consumer DRAM. ECC functionality aids in maintaining data fidelity over time by correcting transient single-bit errors that can result from cosmic rays, electrical noise, or aging. The material and manufacturing standards for RDIMMs are generally higher than for commodity consumer memory, with stronger emphasis on PCB quality, chip binning, and SPD validation. Administrators should plan memory refresh and lifecycle replacements based on server support windows, vendor recommended replacement cycles, and growth forecasts; a conservative approach to replacing modules after several years of heavy use can minimize field failures and unplanned downtime.

Comparisons

Comparing the Dell AA192163 module with alternatives clarifies where it fits in an organization’s memory strategy. Compared with unbuffered ECC UDIMMs, RDIMMs offer better signal integrity and scalability for high-density server configurations. Modules with x8 organization typically have fewer chips per DIMM and are sometimes preferred for specific controller compatibility.
