Server-grade capacity for Supermicro H13DSG-O-CPU

This 128GB DDR5 4800 module delivers registered ECC memory tuned to the exact rank, voltage, and timing the board expects. It targets administrators upgrading or populating that specific Supermicro server platform. Buyers needing unbuffered UDIMM or SODIMM form factors cannot use this kit.

Registered architecture for full-slot population

The 288-pin RDIMM design offloads the memory controller, allowing every supported slot to run fully populated at rated speed without signal degradation. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. Consult the motherboard manual for approved population order and maximum capacity per channel before installation.

Single-module kit with lifetime backing

The package contains one 128GB DDR5 4800 CL40 1.1V 2Rx4 RDIMM ready for immediate installation. No heat spreader is included, so airflow in the chassis must meet the server's thermal requirements. Lifetime replacement coverage and US-based technical support are provided by the manufacturer.

Questions about this item

Does the 2Rx4 registered ECC design let all slots run at 4800 MHz when fully populated?

Yes, the registered architecture offloads the memory controller so every slot runs fully populated at the rated 4800 MHz speed.

How much heat and power should I expect from this 1.10 V module during continuous operation?

At 1.10 V with no heat spreader, the module runs cool and draws minimal power, suited for 24/7 server workloads.

My Supermicro H13DSG-O-CPU board needs DDR5 RDIMMs — will this 288-pin kit install without extra parts?

Yes, the 288-pin DDR5 RDIMM form factor matches the board's slots exactly; no adapters or other components are required.
