128 GB ECC UDIMM kit for servers

This 128 GB kit contains eight 16 GB DDR4 2933 modules built as 2Rx8 unbuffered ECC DIMMs. It is designed for servers and workstations that require error-correcting memory and will not function in standard desktop or laptop systems. Each module runs at the standard 1.2 V DDR4 voltage.

Upgrade from smaller DDR4 ECC UDIMM configurations

The kit replaces lower-capacity DDR4 ECC unbuffered memory to increase total system memory to 128 GB. The jump is worthwhile when workloads exceed the capacity of existing modules and the platform supports 2Rx8 organisation at 2933 MHz with CL21 latency. Compatibility must be verified against the system manual before installation.

Sustained workload behaviour with error correction

Under continuous load the ECC function detects and corrects single-bit errors to maintain data integrity across all eight modules. The dual-rank 2Rx8 layout allows the memory controller to interleave accesses across ranks, helping sustain throughput during extended compute or virtualisation tasks. Modules operate without heat spreaders at the standard 1.2 V level.

Vragen over dit artikel

Will these 288-pin DDR4 modules fit my server's DIMM slots?

Yes, each 16 GB stick uses the standard 288-pin DDR4 DIMM form factor, so it fits any server or workstation slot built for DDR4 ECC UDIMM memory.

Do I need to populate all eight slots at once, or can I add them in pairs?

Install modules in matched pairs per channel following the motherboard manual; mixing ranks or leaving a channel half-populated often causes the system to run at a lower speed or fail POST.

How long before the ECC chips or the 1.20 V power delivery might degrade?

ECC UDIMM modules have no moving parts and run at standard 1.20 V, so they typically last the life of the server; replacement is only needed if a module develops correctable errors that exceed the platform's threshold.
