128GB DDR5 5600 ECC RDIMM

This 128GB DDR5 5600 registered ECC module targets administrators upgrading a Supermicro H13DSH platform. The 2Rx4 organization and CL46 timing match the board's native memory controller expectations so the full capacity is recognized at rated speed.

288-pin registered form factor

The 288-pin RDIMM form factor is the only type the H13DSH accepts, not UDIMM or SODIMM. Registered architecture buffers address and command signals, allowing every slot to be populated at full capacity without overloading the controller. ECC corrects single-bit errors on the fly to prevent silent data corruption.

Sustained enterprise workloads

Operating at 1.1V, the module maintains stability during continuous server workloads rather than short bursts. Registered buffering and on-die ECC keep signal integrity consistent across fully populated channels, reducing unplanned reboots in production environments.

Questions about this item

How many DIMM slots does the Supermicro H13DSH board provide for this 128 GB DDR5-5600 kit?

The Supermicro H13DSH motherboard is a dual-socket SP5 platform with 12 DDR5 RDIMM slots per socket, giving 24 slots total. This 128 GB module occupies one slot; full population would require 24 identical modules.

Does the registered ECC design keep power draw low enough for continuous 24/7 server operation?

Each module runs at the standard DDR5 1.10 V and uses a registered buffer that off-loads the memory controller. That combination is what enterprise platforms expect for sustained full-capacity operation without thermal throttling.

What motherboard revision or BIOS version must already be installed for this DDR5-5600 RDIMM to be recognised at full speed?

Supermicro specifies the H13DSH for DDR5-5600 registered ECC DIMMs. The board’s memory controller and SPD hub will train the module at 5600 MT/s CL46 2Rx4 1.10 V provided the BIOS supports the SP5 memory reference code for that speed grade.
