What server platforms support the HMCG84AHBRA292N?

Compatible with Intel Xeon 6th Gen (Granite Rapids), AMD EPYC 9005 (Turin) series and later platforms supporting DDR5-6400 RDIMMs. Requires server motherboards with 288-pin DDR5 slots and BIOS firmware enabling 6400MT/s operation for full performance.

Does this module support high-density configurations?

Yes, the registered RDIMM design with clock driver supports up to 8 DIMMs per channel in dual-channel setups. 1Rx4 rank optimizes signal integrity for maximum capacity populations in 2U/4U enterprise servers.

What is the power consumption of this DDR5 module?

Operates at 1.1V with on-module PMIC managing power delivery efficiently. Typical active power around 5-7W per module under load, significantly lower than DDR4 equivalents while delivering 6400MT/s bandwidth.

Is ECC functionality hardware-based?

Yes, full hardware ECC detects and corrects single-bit errors on-the-fly. Server CPU memory controller handles correction transparently, ensuring data integrity without software intervention or performance penalty.

What are the physical dimensions for rack integration?

Standard RDIMM profile: 1.00 inch height x 6.75 inch depth x 0.20 lb weight. Fits all standard 288-pin server slots in rackmount chassis from Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem.

Can this mix with other DDR5 speeds?

All modules in a channel must match speed and rank for stability. Server BIOS downclocks to lowest common speed if mixing, but matched HMCG84AHBRA292N sets recommended for optimal 6400MT/s performance.

Product overview

The SK Hynix HMCG84AHBRA292N is a 32GB DDR5-6400 ECC Registered DIMM (RDIMM) designed for enterprise server and workstation environments requiring high reliability and data integrity. Featuring PC5-51200 speed rating, 1Rx4 single rank configuration, and CL52 CAS latency, this 288-pin module operates at 1.1V for optimal power efficiency. The ECC functionality detects and corrects single-bit errors, ensuring uninterrupted operation in mission-critical applications like virtualization, databases, and cloud infrastructure. Compared to DDR4 predecessors, DDR5 architecture delivers up to 70% higher effective bandwidth with improved power management through on-module PMIC and decision feedback equalization. The registered design buffers command/address signals, supporting high-density memory populations without signal degradation. Ideal for Intel Xeon and AMD EPYC platforms supporting DDR5, this module enables scalable memory configurations up to server maximums while maintaining stability under heavy workloads. With dimensions of approximately 1.00" H x 6.75" D and lightweight 0.20 lb construction, it integrates seamlessly into standard 288-pin server slots. Targeted at enterprise IT deployments, it provides the performance and endurance needed for 24/7 operations in data centers, HPC clusters, and business-critical systems, balancing speed, capacity, and reliability for long-term ROI.
