32GB DDR5 4800 ECC UDIMM for servers

This module delivers 32GB of DDR5 memory at 4800MHz with ECC error correction for server and workstation platforms. It operates at 1.10V with CL40 latency in a 2Rx8 unbuffered configuration. The 288-pin DIMM fits standard DDR5 slots and replaces Hynix HMCG88MEBEA modules. Systems without DDR5 slots cannot use this memory.

Practical limits of DDR5 4800 ECC unbuffered

The 4800MHz speed and CL40 timing set the baseline bandwidth and latency for this standard. ECC adds single-bit correction and multi-bit detection for data integrity in critical workloads. Unbuffered design means the memory controller drives each module directly, which limits the number of modules per channel compared to registered alternatives. Motherboards must support DDR5 ECC UDIMMs at this speed and voltage to enable full functionality.

Build quality and daily handling

The module uses major-brand chipsets and undergoes quality-assurance testing for dependable operation in continuous server environments. A 262-pin edge connector matches the DDR5 DIMM keying to prevent mis-insertion. The 1.1V operating voltage aligns with the DDR5 standard for reduced power draw. Installers should verify platform compatibility before purchase to ensure the system recognises the ECC unbuffered configuration.

Questions about this item

Should I choose a single 32 GB stick or add a second one for dual-channel?

This module provides 32 GB in one stick; a second identical module enables dual-channel on boards that support it.

What does DDR5 4800 CL40 deliver in a real server workload?

The 4800 MT/s data rate with CL40 latency and 1.10 V gives high throughput for ECC-protected workloads on compatible platforms.

How does the 288-pin DDR5 UDIMM interface limit speed and capacity?

The 288-pin unbuffered DDR5 interface runs at 4800 MT/s per module; maximum system capacity depends on the motherboard's slot count and memory controller.
