32GB DDR5 ECC SODIMM for microservers

This 32GB DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It uses a 262-pin SO-DIMM form factor and includes on-die ECC for data integrity. The unbuffered design suits compatible microserver and workstation platforms.

Sustained load stability with ECC

Error-correcting code detects and corrects single-bit errors during continuous operation, preventing silent data corruption in long-running workloads. The standard DDR5 voltage maintains consistent signalling without elevated power draw. Unbuffered topology keeps latency predictable under sustained memory pressure.

DDR5 4800 interface practical limits

The PC5-38400 rating defines the maximum JEDEC-standard data rate for this module. Systems that only support lower DDR5 speeds will clock the memory down automatically. Platforms requiring registered DIMMs or higher-density configurations cannot use this unbuffered SODIMM.

Questions about this item

How much heat and power does the 1.10V DDR5 4800 module produce when running continuously in a NAS or microserver?

The module operates at the standard DDR5 1.10V without a heat spreader, keeping power draw low and thermals manageable for always-on workloads.

What must my system already provide for this 262-pin ECC SODIMM to function?

A DDR5 SO-DIMM slot that supports unbuffered ECC memory at 4800MHz and a platform qualified for the Hynix HMCG88MEBAA092N part.

Will this CL40 DDR5 4800 stick work alongside the Hynix HMCG88MEBAA092N modules already in my server?

Yes, it is built as a compatible replacement for that exact Hynix part number, matching speed, voltage, rank and ECC type.
