128GB DDR5 RDIMM for Supermicro H14DST-F

This 128GB DDR5 5600MHz ECC Registered RDIMM is built for the Supermicro H14DST-F motherboard. It delivers 2Rx4 rank organisation at 1.1V with CL46 timing so the memory controller recognises the full capacity immediately. The 288-pin form factor matches the board's DIMM slots exactly. Server administrators upgrading production systems get the precise module specification the platform expects.

Registered ECC limits for DDR5 5600

Registered buffering offloads the memory controller, allowing every slot to run fully populated at the rated 5600MHz speed. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. The DDR5 standard at this frequency requires the registered architecture for stable operation across all populated channels. Builders using unbuffered UDIMMs or SODIMMs will find they do not fit or function in this server platform.

288-pin RDIMM build and daily handling

The module uses major OEM Samsung, Micron or Hynix chips without a heat spreader, keeping the profile low for dense server chassis airflow. The 288-pin Registered edge connector keys only into DDR5 RDIMM slots, preventing accidental insertion into incompatible sockets. Installation follows the motherboard manual's population order to ensure full capacity recognition. Buyers needing consumer desktop memory or non-ECC modules cannot use this part in those systems.

Questions about this item

Should I choose the 128GB DDR5-5600 2Rx4 RDIMM or a different capacity for my Supermicro H14DST-F?

This module provides exactly 128GB in a single 288-pin RDIMM at 5600MHz with CL46 timing and 1.10V. Your motherboard manual lists the approved population order and maximum capacity per slot, so check that first to confirm this density fits your planned configuration.

Will this DDR5-5600 CL46 kit actually run at 5600MHz once installed in the H14DST-F?

The module is specced for DDR5 5600 (PC5-44800) with CL46 at 1.10V. The Supermicro H14DST-F memory controller negotiates speed at boot; with the correct population order it will recognise the 2Rx4 rank structure and operate at the rated 5600MHz.

Is the 288-pin RDIMM interface on this kit the same as a standard UDIMM, and does it limit how many modules I can populate?

No, this is a 288-pin Registered (RDIMM) DDR5 module, not a UDIMM. The registered buffer reduces electrical load on the memory controller, allowing the H14DST-F to run every supported slot fully populated at the rated 5600MHz without signal degradation.
