Server-grade ECC UDIMM kit

This 32 GB kit contains eight 4 GB DDR4 2133 modules built for servers and workstations that require error-correcting unbuffered memory. Each stick is a single-rank 1Rx8 design running at 1.2 V with CL15 latency. The modules are not compatible with standard desktop or laptop platforms.

Steady throughput on multi-core workloads

ECC circuitry corrects single-bit errors in real time, preventing silent data corruption during long compute runs or virtualization tasks. Unbuffered topology keeps latency low across all populated channels, while the single-rank layout helps the memory controller maintain consistent timing under sustained load.

Plain green PCB fits dense DIMM arrays

The 288-pin UDIMM form factor slots directly into standard server boards without extra height from heat spreaders. Major-brand chips are tested for reliability before shipping, and the kit arrives as eight matched modules to simplify channel population.

Questions about this item

How much power does each 4 GB DDR4 2133 module draw at the rated 1.2 V?

Each module operates at the standard DDR4 voltage of 1.20 V; actual wattage depends on the server platform and workload.

What motherboard slots and memory controller support are required for this 8 x 4 GB ECC UDIMM kit?

The kit needs eight 288-pin DDR4 UDIMM slots and a CPU or chipset that supports ECC unbuffered DDR4 2133 memory.

Will these single-rank 1Rx8 DDR4 2133 ECC UDIMMs work alongside older DDR4 registered DIMMs in the same server?

No — unbuffered ECC UDIMMs and registered ECC RDIMMs cannot be mixed; all slots must use the same module type.
