Exact-fit 48 GB DDR5 RDIMM for Supermicro H13DSH

This 48 GB DDR5-6400 module matches the Supermicro H13DSH memory controller with CL52 timing, 1.1 V operation and 2Rx8 registered ECC architecture. It is built for servers that require full-capacity recognition and error correction at rated speed.

Simple slot installation with population rules

The 288-pin RDIMM seats in the standard DDR5 DIMM slots, but the motherboard manual defines the supported capacities and required population order. Skipping those rules can leave capacity unseen or force the system to run at reduced speeds.

48 GB per module handles heavy virtualization

Registered buffering offloads the controller so every populated slot runs at the full 48 GB, while ECC corrects single-bit errors before they corrupt data. Applications that exceed per-slot limits or need unbuffered UDIMM form factors cannot use this module.

Questions about this item

How can I verify the module is running at 6400 speed with CL52 after installation?

Check the BIOS memory information screen or use a tool such as CPU-Z; the SPD should report DDR5-6400 (PC5-51200) with a CAS latency of 52 at 1.1 V.

What exactly ships in the box and is anything else required?

The package contains one 48 GB 288-pin DDR5 ECC registered RDIMM; no heat spreader, cables or additional parts are included or needed for installation.

Should I choose the 48 GB 2Rx8 version or a different capacity for the Supermicro H13DSH?

This 48 GB 2Rx8 RDIMM matches the board's validated population rules; consult the motherboard manual for approved capacities and slot order before selecting a different size.
