128 GB DDR5 ECC UDIMM kit

This 128 GB kit contains four 32 GB DDR5 5600 modules with ECC and a CAS latency of 46. The unbuffered 2Rx8 design runs at 1.1 V and uses 288-pin DIMMs built with major OEM chips. It is intended for servers and workstations that require error-correcting memory at this speed and density.

Suited for ECC UDIMM platforms.

These modules fit systems that accept unbuffered ECC DDR5 UDIMMs at 5600 MT/s. They will not work in motherboards that require registered or load-reduced DIMMs, nor in platforms limited to non-ECC consumer memory. Buyers needing higher capacities per slot or registered memory should look elsewhere.

DDR5 5600 unbuffered ECC specification

The decisive specification is DDR5 5600 unbuffered ECC with 2Rx8 organisation. Verify that your motherboard and CPU support this exact combination before purchase; a mismatch in buffering, ECC type or speed will prevent the kit from functioning.

Questions about this item

Will the 288‑pin DDR5 ECC UDIMM modules fit my server’s standard DIMM slots?

Yes, each 32 GB module uses the 288‑pin DDR5 UDIMM form factor, matching the standard slot layout for DDR5 unbuffered ECC memory.

What is the correct seating procedure for the 2Rx8 modules, and what step is often missed?

Align the notch with the slot key, press straight down until both retention clips click; the step often missed is verifying both clips are fully latched after insertion.

When should I consider replacing the 1.1 V DDR5 5600 kit?

Replace modules if memory diagnostics report uncorrectable ECC errors, the system fails POST with memory codes, or stability issues persist after reseating and firmware updates.
