16GB DDR5 4800 ECC SODIMM for Microserver Upgrades

This A-Tech module delivers 16GB of DDR5 memory at 4800MHz with ECC error correction for data integrity. It uses a 262-pin SO-DIMM form factor and operates at the standard 1.10V voltage. The unbuffered 1Rx8 design targets microserver, server, and workstation systems needing reliable capacity expansion.

Hynix HMCG78MEBAA092N Direct Replacement

The module is built as a compatible replacement for the specific Hynix HMCG78MEBAA and HMCG78MEBAA092N part numbers. Major brand DRAM IC chips are used throughout, and every unit undergoes quality assurance testing to verify dependable performance. This ensures a straightforward upgrade path for systems originally equipped with those Hynix modules.

Suits ECC SO-DIMM Slots Needing 1Rx8 Unbuffered DDR5

This memory fits platforms requiring unbuffered ECC SO-DIMMs with a 1Rx8 rank configuration at DDR5 4800 speeds. Builders needing registered or buffered modules, higher capacities per slot, or different pin counts should look at other options. Systems without ECC support in the chipset or BIOS will not utilise the error-correction capability.

Questions about this item

Does the 1Rx8 ECC module require any periodic maintenance or component replacement?

No, the DDR5 SODIMM has no moving parts or user-serviceable components; once seated in the 262-pin slot it runs maintenance-free for its service life

What limit appears first during sustained workloads on this 4800 MT/s stick?

The fixed CAS latency of 40 cycles and the 1.10 V operating voltage set the throughput ceiling before thermal throttling becomes a factor

How much noise, heat or power does the 16 GB module add when running all day?

At 1.10 V the module draws minimal power and generates little heat; with no heat spreader it relies on normal chassis airflow, keeping noise unchanged
