A-Tech 32GB DDR5 5600 ECC RDIMM 2Rx8 for Hynix HMCG88AGBRA server RAM

32GB DDR5 5600 ECC RDIMM for servers

This 32GB registered DIMM operates at 5600 MT/s with a CAS latency of 40 and a standard 1.10 V voltage. It uses a 2Rx8 organisation and major-brand DRAM ICs on a 288-pin DDR5 form factor. The module is built as a compatible replacement for Hynix HMCG88AGBRA and the 188N, 190N, 191N, 192N part numbers. It targets server and workstation platforms that require ECC error correction.

Sustained-load behaviour with registered ECC

The registered buffer reduces electrical load on the memory controller, helping maintain signal integrity when all channels are populated. ECC circuitry corrects single-bit errors and detects multi-bit errors during continuous operation, protecting data integrity under heavy workloads. The module runs at the JEDEC-standard 1.10 V, keeping power draw predictable during extended duty cycles. No heat spreader is fitted, so chassis airflow must carry away the heat generated by the DRAM chips.

Pre-order checklist for your platform

Verify that your motherboard supports DDR5 RDIMMs and accepts 2Rx8 modules at 5600 MT/s. Confirm the maximum registered DIMM capacity per slot and the total number of slots available. Check the system manual for required population rules and channel configurations. Ensure the BIOS is updated to a version that recognises this module density and rank structure. Buyers needing unbuffered UDIMMs or a different rank configuration should look elsewhere.
