  • 128 GB total capacity for memory-intensive workloads using two 64 GB modules
  • DDR5 5600 MHz speed delivers high bandwidth with PC5-44800 rating
  • Registered ECC design corrects single-bit errors and buffers signals for full-slot stability
  • CL46 latency at 1.1 V balances response time with server-grade power efficiency
  • Validated for Supermicro H14DSH motherboard ensuring correct 288-pin RDIMM fitment

System-Specific DDR5 Upgrade

This 128GB kit contains two 64GB DDR5 5600MHz Registered ECC RDIMMs built for the Supermicro H14DSH motherboard. It targets server administrators who need exact-match memory that the platform recognises at full capacity and rated speed.

Verified Fitment and Enterprise Stability

The modules use the 288-pin RDIMM form factor, 1.1V operation, CL46 timing and 2Rx4 organisation required by the board's memory population rules. Registered architecture offloads the memory controller so every slot runs fully populated, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

Build Quality and Daily Implications

Major OEM DRAM from Samsung, Micron or Hynix underpins the kit, though no heat spreader is fitted so airflow across the DIMMs must be adequate. Buyers who need a different capacity, UDIMM or SODIMM form factors, or non-ECC memory cannot use this product.

Questions about this item

Will the 2Rx4 registered ECC RDIMMs need any firmware updates or periodic reseating during their service life?

No firmware updates or scheduled reseating are required; the 2Rx4 registered ECC RDIMMs are designed for continuous operation once installed in the Supermicro H14DSH motherboard.

What limits sustained throughput when all slots are populated with these 5600 MT/s CL46 modules?

The DDR5 5600 MT/s CL46 timing and 1.1 V voltage set the maximum sustained data rate; the memory controller on the H14DSH governs actual throughput under full load.

How much heat and power does the 128 GB kit draw when running 24/7 at rated speed?

Each 64 GB module operates at 1.1 V DDR5 standard voltage without a heat spreader, so total power draw and thermal output stay within normal registered DIMM limits for the platform.
