Exact-Match DDR5 RDIMM Upgrade

This 128GB DDR5-4800 registered ECC module is built for the Supermicro H13DSG-OM motherboard. It delivers the precise 2Rx4 rank structure, 1.1V operating voltage, and CL40 timing the board's memory controller expects for full-capacity recognition at rated speed.

Verified Fitment for H13DSG-OM

The 288-pin RDIMM form factor matches the required registered architecture, not UDIMM or SODIMM. Major OEM Samsung, Micron, or Hynix chips provide enterprise stability with on-the-fly single-bit error correction to prevent silent data corruption in production workloads.

Check Population Rules Before Ordering

Server memory support varies by model and BIOS revision. Consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps to ensure compatibility with your specific configuration.

Questions about this item

Will the 128GB DDR5 RDIMM need any periodic maintenance or component replacement during its service life?

The module has no moving parts and no heat spreader, so it requires no scheduled maintenance or component replacement under normal operating conditions.

What is the first limit reached when the 128GB DDR5 4800MHz CL40 RDIMM runs at full load continuously?

The CAS latency of CL40 and the fixed 4800 MT/s data rate define the timing ceiling; sustained throughput cannot exceed the rated PC5-38400 bandwidth.

How much heat and power does the 1.1V 2Rx4 ECC Registered DDR5 module produce when the server runs all day?

At 1.1 volts the module draws minimal power and generates low heat; with no heat spreader it relies on chassis airflow to stay within thermal limits.
