Exact-fit server upgrade

This 128GB kit delivers eight 16GB DDR5 RDIMMs built to the precise 1Rx8 rank, 1.1V voltage and CL40 timing the Supermicro H13DSG-O-CPU-D memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly so every slot runs fully populated at rated speed without silent data corruption.

Sustained-load stability

Registered buffering keeps signal integrity intact across all eight slots during continuous multi-threaded workloads while ECC corrects single-bit errors in real time preventing silent data corruption and unplanned reboots. The modules operate at the standard 1.1V DDR5 voltage maintaining thermal headroom inside dense server chassis.

288-pin DDR5 RDIMM form factor

The kit only fits motherboards that accept 288-pin registered DDR5 DIMMs and cannot be used in boards requiring UDIMM, SODIMM or any earlier DDR generation. Verify your platform manual for supported capacities and population order before purchase.

Questions about this item

How much power does the 1.1V DDR5 kit draw when the server runs all day?

Each module operates at 1.10V; total system draw depends on CPU load and motherboard regulation.

What motherboard slot and population rules must my Supermicro H13DSG-O-CPU-D already have for this 8×16GB kit to work?

The board needs eight 288-pin RDIMM slots and must support 1Rx8 registered ECC population per the manual.

Can I mix these 1Rx8 CL40 RDIMMs with older DDR5 modules of different rank or latency in the same server?

Mixing ranks or timings is not recommended; the memory controller expects identical 1Rx8 CL40 modules for stable operation.
