Size 64GB 2X32GB

  • 64 GB capacity from two 32 GB modules for full population
  • DDR5 5600 MHz speed rated at PC5-44800 for rated throughput
  • ECC registered design corrects single-bit errors and buffers every slot
  • 10 V operation at CL46 latency matches controller expectations
  • 288-pin RDIMM form factor verified for Supermicro X14SDI-36C-SP3F

Exact-fit server upgrade

This 64 GB kit provides two 32 GB DDR5 RDIMMs built to the precise rank, voltage and timing the Supermicro X14SDI-36C-SP3F memory controller expects. Registered ECC architecture offloads the controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly. The 288-pin form factor matches the board's required RDIMM layout.

Sustained-load stability

Registered buffering keeps electrical loading low across all channels, allowing the memory subsystem to maintain 5600 MT/s throughput during continuous workloads without throttling. ECC detection and correction runs on every transaction, preventing silent data corruption that would otherwise accumulate under long-running compute or database tasks. The 1.1 V operating voltage supports consistent thermal behaviour in densely populated server chassis.

DDR5 interface limits

The PC5-44800 standard caps per-pin transfer rate at 5600 MT/s, so this kit cannot exceed that bandwidth regardless of processor capability. CL46 latency is fixed by the module's SPD profile and cannot be tightened without violating the validated specification. Population rules for the X14SDI-36C-SP3F restrict maximum capacity per channel, so adding further DIMMs beyond the board's approved layout will not increase usable memory.

Questions about this item

How much power does the 5600 MHz kit draw at 1.1 V when the server runs continuously?

The modules operate at 1.1 V with DDR5 5600 speed and CL46 timings, a combination designed for stable power draw in fully populated registered DIMM configurations.

What motherboard feature must my Supermicro X14SDI-36C-SP3F already provide for these RDIMMs to function?

The board must support 288-pin DDR5 Registered ECC memory with 2Rx8 organization and PC5-44800 data rate so the memory controller can initialise the kit at its rated 5600 MHz.

Will the 2Rx8 registered ECC modules work in the remaining slots if I keep older single-rank DDR5 RDIMMs installed?

Mixing 2Rx8 registered ECC DIMMs with different rank counts is not guaranteed; the X14SDI-36C-SP3F manual should be consulted for approved population rules before combining them.
