32 GB DDR5 ECC Unbuffered Module

This 32 GB DDR5 SDRAM module operates at 4800 MHz with CL40 latency and 1.10 V voltage. It features ECC error correction and an unbuffered design in a 288-pin form factor using Hynix A-die chips. The dual-rank 2Rx8 organisation supports data integrity for server and workstation workloads.

Suited for DDR5 platforms accepting unbuffered ECC

Builders populating servers or workstations that support unbuffered ECC memory at 4800 MHz will find this module compatible. Systems requiring registered or load-reduced DIMMs cannot use this kit. Platforms limited to earlier DDR generations or those needing speeds above 4800 MHz or latencies tighter than CL40 should consider other options.

Unbuffered ECC with dual-rank 2Rx8 organisation

The unbuffered signal path combined with ECC and a dual-rank 2Rx8 layout is the specification that determines fit. Motherboards must explicitly support unbuffered ECC DDR5 at this rank configuration; registered-only or non-ECC platforms will not accept the module.

Questions sur cet article

Will the Hynix A-DIE chips on this 32 GB DDR5 module need any firmware updates or re-training over time?

No firmware updates are required for the Hynix A-DIE ICs; the module runs at its rated 4800 MT/s with 40-39-39 timings for its service life.

What limit appears first when this dual-rank 2Rx8 stick runs continuously at 4800 MT/s?

The JEDEC-standard 1.10 V operating voltage sets the thermal ceiling before frequency or latency thresholds are reached.

How much heat and power does a single 32 GB DDR5 4800 CL40 module produce under all-day load?

At the specified 1.10 V the module draws only its rated power, generating modest heat that standard server airflow handles without extra cooling.
