The SK hynix HMCG88AEBRA115N is a 32GB DDR5-4800 dual-rank registered ECC DIMM (2Rx8 RDIMM) designed for high-density enterprise server environments. Operating at an energy-efficient 1.1V nominal supply, it provides up to 38.4 GB/s of peak bandwidth alongside enterprise-grade data integrity. It is optimized for 4th and 5th Gen Intel Xeon Scalable and AMD EPYC 9004 series server platforms.
The HMCG88AEBRA115N is built on SK hynix 16Gb DDR5 SDRAM monolithic dies organized in a dual-rank x8 (2Rx8) configuration. The part number decodes systematically: 'HM' signifies SK hynix module, 'C' designates DDR5 SDRAM, 'G' denotes an RDIMM form factor, '88' specifies 32GB density with a 2Rx8 organization, 'A' indicates 16Gb component density, 'EB' reflects die revision and package type, and '115' identifies the DDR5-4800 speed bin with standard JEDEC CL40 latency. DDR5 splits the traditional 64-bit data bus into two independent 32-bit subchannels (each with 8-bit ECC overhead, creating two 40-bit channels) to enhance memory concurrency, reduce latency, and boost effective channel efficiency.
The module features a JEDEC-standard Registering Clock Driver (RCD) that buffers Command/Address signals, an onboard Power Management IC (PMIC) converting host 12V power to 1.1V VDD/VDDQ and 1.8V VPP directly on the module, and an integrated SPD Hub with thermal sensing. Reliability is reinforced via a dual-layer error mitigation scheme combining internal DRAM on-die ECC (ODECC) for single-bit defect scrubbing with module-level sideband ECC processed by the host CPU memory controller.
Always verify against your server's qualified vendor list (QVL).
No. DDR5 RDIMMs feature an entirely different key notch position, pin layout (288 pins with different signal assignments), and on-module power architecture (PMIC) that make them physically and electrically incompatible with DDR4 slots.
2Rx8 indicates a dual-rank module using x8-wide DRAM chips. While x4 modules support advanced chipkill/multi-bit device correction more granularly, 2Rx8 modules provide rank interleaving benefits on single-DIMM-per-channel deployments at a cost-effective price point for 32GB configurations.
Yes. The JEDEC SPD profiles programmed on the module allow it to operate at supported lower clock rates if required by the host processor or memory population rules, provided the host supports DDR5 RDIMMs.
