Speed 5600MHz

  • 512 GB total capacity from four 128 GB modules
  • DDR5 5600 speed with CL46 latency for rated throughput
  • Registered ECC design corrects single-bit errors automatically
  • 1 V operation matches the motherboard specification exactly
  • 288-pin RDIMM form factor fits the Supermicro H14DSH slots

Server Memory Kit for Supermicro H14DSH

This 512GB kit contains four 128GB DDR5 5600 RDIMM modules built to the exact rank, voltage and timing the Supermicro H14DSH memory controller expects. Registered ECC architecture allows every slot to run fully populated at rated speed while correcting single-bit errors on the fly. The 288-pin form factor matches the board's physical requirements.

512GB Capacity with 2Rx4 Organisation

Four dual-rank modules deliver 512GB total, providing headroom for large virtualisation clusters, in-memory databases and high-thread-count compute workloads. The 2Rx4 layout keeps electrical load manageable across all channels, though the registered buffer adds one cycle of latency compared with unbuffered alternatives. Maximum capacity is defined by the motherboard's supported population rules.

DDR5 5600 Registered ECC Interface Limits

The DDR5 5600 (PC5-44800) interface operates at 1.1V with CL46 timing, setting the bandwidth and latency ceiling for this platform. Registered signalling reduces electrical stress on the memory controller but does not increase the peak data rate beyond the JEDEC 5600 MT/s specification. Systems requiring higher throughput or lower latency must use a platform that supports faster DDR5 speeds.

Questions about this item

Will the 2Rx4 registered DDR5 modules run at 5600 MHz alongside any existing RDIMMs I keep in the Supermicro H14DSH?

The kit is spec-matched to the H14DSH memory controller at DDR5-5600 CL46 1.1 V. Mixing ranks or speeds can force the board to down-clock; populate all slots with identical 2Rx4 RDIMMs for full rated performance.

How can I verify the 512 GB kit is detected at full speed and ECC is active after installation?

Enter the BIOS or UEFI and confirm the memory frequency shows 5600 MT/s, total capacity reads 512 GB, and ECC status reports enabled for each channel.

Does the box contain only the four 128 GB RDIMMs or are any brackets, cables or tools included?

The package content lists only the 512 GB 4×128 GB DDR5-5600 CL46 288-pin ECC registered RDIMM kit; no additional brackets, cables or tools are supplied.
