Speed 5600MHz

  • 768 GB total capacity for memory-intensive workloads with six 128 GB modules
  • DDR5 5600 speed rated at PC5-44800 for high throughput
  • ECC Registered RDIMM design corrects single-bit errors and stabilises fully populated slots
  • 1 V operation with CL46 latency matches the board's memory controller spec
  • 288-pin 2Rx4 form factor verified for Supermicro H13SVW-N motherboard

Exact-match server upgrade

This 768GB kit delivers six 128GB DDR5 5600 RDIMM modules built for the Supermicro H13SVW-N motherboard. Each stick runs at 1.1V with CL46 timing and a 2Rx4 registered ECC layout that matches the board's memory controller requirements.

Registered ECC stability

The registered architecture buffers address and command signals so all slots stay stable when fully populated. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

Slot-order installation

Populate the DIMMs in the sequence specified by the Supermicro manual to avoid a no-post condition. The 288-pin RDIMM form factor fits only registered slots; UDIMM or SODIMM sockets will not accept these modules.

Questions about this item

Will the 128GB RDIMM modules or their ECC function need replacement over time?

Registered ECC DDR5 modules have no moving parts and the ECC logic is built into each DRAM die, so the kit does not require scheduled replacement; the motherboard firmware will flag a correctable error count if a module ever degrades.

What limits sustained throughput when all six slots are populated at DDR5-5600?

The memory controller on the Supermicro H13SVW-N enforces the official JEDEC DDR5-5600 data rate, so bandwidth caps at the rated 5600 MT/s per channel regardless of load duration.

How much heat and power do the 1.1V 2Rx4 RDIMMs generate during continuous operation?

Each module runs at 1.1 V without a heat spreader; total kit power scales with the six 128GB ranks, and airflow across the bare PCBs keeps temperatures within the DDR5 JEDEC thermal envelope.
