Exact-match DDR5 ECC kit

This 128GB kit delivers four 32GB DDR5 5600 modules built to the PC5-44800 standard. It targets administrators and engineers who run Supermicro H13SRD-F or H13SRE-F motherboards and need validated ECC memory for production workloads.

Unbuffered UDIMM fit

Each module uses the 288-pin unbuffered ECC UDIMM form factor that these boards require, not an RDIMM or SODIMM. The 2Rx8 rank structure and 1.10V operating voltage match the memory controller expectations so the full capacity is recognised at rated speed.

ECC protection included

On-die error correction detects and corrects single-bit errors automatically, reducing silent data corruption and unplanned reboots. The kit contains only the four memory modules; no heat spreaders or additional software are supplied.

Questions about this item

What sustained thermal limit appears first when all four 32 GB DDR5 5600 modules run continuously?

The modules operate at the standard 1.10 V with no heat spreader, so the first limit is the motherboard DIMM-slot temperature threshold rather than a module-side thermal throttle.

How much acoustic noise or extra power draw do the bare 2Rx8 ECC UDIMMs add during all-day workloads?

They have no fans or active cooling and draw only the 1.1 V DDR5 baseline, so they add no audible noise and negligible extra power beyond the memory controller budget.

Which motherboard must already be installed for this 288-pin DDR5 5600 ECC UDIMM kit to function?

The kit is validated for the Supermicro H13SRD-F or H13SRE-F motherboard that accepts 288-pin unbuffered ECC DDR5 5600 DIMMs.
