Server DDR5 ECC RDIMM 32GB

This A-Tech module delivers 32GB of DDR5 4800 registered ECC memory for server and workstation platforms. It operates at 1.10V with CL40 latency and a 2Rx8 organisation. The 288-pin DIMM is built as a direct replacement for Hynix HMCG88MEBRA113N, HMCG88MEBRA115N and HMCG88MEBRA174N part numbers.

Registered ECC with 2Rx8 layout

The registered buffer and on-die ECC protect data integrity in multi-module configurations. A 2Rx8 rank structure allows higher density per channel without exceeding typical platform rank limits. Verify that your motherboard supports DDR5 RDIMM at 4800MT/s and the required rank population rules before installation.

Tested replacement module

Each unit undergoes A-Tech quality-assurance testing to confirm reliability at rated speed and voltage. The module ships as a single 32GB stick with no additional cables, brackets or software utilities included. Lifetime warranty and US-based technical support are provided by the manufacturer.

Questions about this item

What does the 4800 MT/s rating mean for real throughput in a server?

The module runs at 4800 MT/s with a PC5-38400 rating; actual throughput depends on the platform's memory controller and channel configuration

How does the DDR5 interface and ECC RDIMM design affect compatibility?

This is a DDR5 288-pin registered DIMM with on-die ECC and a register; it only fits DDR5 RDIMM slots and requires a platform that supports registered memory

What physical space and slot type does this 262-pin DIMM need?

The module uses the standard DDR5 288-pin DIMM form factor (not 262-pin SO-DIMM) and requires a full-height RDIMM slot with 1.1 V support
