128GB DDR5 5600 Registered ECC RDIMM

This 128GB DDR5 5600MHz PC5-44800 module is a 288-pin Registered ECC RDIMM built for the Supermicro X14SRG-TF motherboard. It runs at 1.1V with CL46 latency and a 4Rx4 organisation. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at rated speed.

Verified fitment for Supermicro X14SRG-TF

The module uses the 288-pin Registered RDIMM form factor that this motherboard requires, not a UDIMM or SODIMM. Spec-matched population rules mean the DIMM installs in the correct slot order without manual trial and error. Registered buffering offloads the memory controller so every populated slot runs at full capacity, while ECC corrects single-bit errors on the fly to stop silent data corruption.

Capacity and headroom for dense workloads

A single 128GB stick provides the maximum density this slot accepts, letting memory-heavy databases, virtualisation hosts or analytics jobs keep working sets in RAM. Registered architecture allows full-slot population without signal degradation, so total system memory scales to the board's limit. Workloads that exceed 128GB per slot or need unbuffered UDIMMs will require a different platform.

Questions about this item

Will the 4Rx4 ECC Registered RDIMM modules need any firmware updates or component replacements over their service life?

The modules are solid-state with no moving parts and no user-serviceable components, so no firmware updates or part replacements are required during normal operation.

What limit appears first when the 128GB DDR5-5600 kit runs at full load continuously?

The memory controller's thermal and power envelope is the first bottleneck; the DRAM itself is rated for 1.10 V at 5600 MT/s and will not throttle before the platform does.

How much heat and power do the 288-pin RDIMMs produce when the server runs all day?

Each DIMM operates at 1.10 V without a heat spreader, so power draw stays within standard DDR5 RDIMM limits and passive airflow in a server chassis is sufficient for cooling.
