Exact-match upgrade for Supermicro H13DSG-O-CPU-D

This 256GB kit contains two 128GB DDR5 4800 RDIMMs built to the board's required 2Rx4 registered ECC specification. It delivers the precise rank, voltage and timing the memory controller expects so the full capacity is recognised at rated speed.

Sustained-load behaviour

Registered architecture offloads the memory controller allowing every slot to run fully populated at full capacity without throttling. ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots during continuous production workloads.

Installation and common issues

The 288-pin RDIMM form factor fits only the board's registered DIMM slots; UDIMM or SODIMM modules will not seat. Consult the motherboard manual for supported capacities and the approved population order before installing to avoid a no-post condition.

Questions sur cet article

How much power does this 1.10 V DDR5 kit draw when the server runs 24/7?

The modules operate at 1.10 V, the standard voltage for DDR5 RDIMMs, so power draw per DIMM is lower than previous DDR generations at full load.

What motherboard slot and population rules are required for this 288-pin RDIMM kit?

The kit needs a Supermicro H13DSG-O-CPU-D motherboard with DDR5 RDIMM slots; consult the board manual for the approved 2Rx4 population order before installing both 128 GB modules.

Can I mix these 2Rx4 Registered ECC modules with other DDR5 RDIMMs of different rank or speed in the same server?

Mixing ranks or speeds is not recommended; the memory controller expects identical 2Rx4 CL40 modules at 4800 MT/s for stable operation across all populated channels.
