Supermicro H13SSH-E Memory Upgrade

This 128GB DDR5-4800 Registered ECC RDIMM is built to the exact specification the Supermicro H13SSH-E motherboard requires. It delivers 128GB of capacity in a single 288-pin module rated at PC5-38400 with CL40 latency and 1.10V operation. The 2Rx4 registered architecture ensures the memory controller recognises the full capacity at rated speed.

Server Builders Needing Verified Fitment

This module suits administrators upgrading or populating a Supermicro H13SSH-E system where registered ECC memory is mandatory for stability and data integrity. It is not for desktop or workstation boards that accept only unbuffered UDIMMs, nor for laptops requiring SODIMM form factors. Buyers who need a different capacity, speed, or rank configuration should consult their motherboard manual for the supported population rules.

128GB DDR5-4800 2Rx4 Registered ECC

The single specification that decides fitment is the 128GB DDR5-4800 2Rx4 Registered ECC RDIMM profile at 1.10V CL40. Your server's memory controller expects this precise rank, voltage, and timing combination to initialise at full capacity and rated frequency. Verify the H13SSH-E manual for approved DIMM population order before installation.

Questions about this item

Does the 128GB DDR5 4800 kit include everything needed for the Supermicro H13SSH-E or are extra parts required?

The kit provides the 128GB 288-pin DDR5 RDIMM module itself; no cables, brackets or additional components are included and none are required for installation.

How do I decide between the 2Rx4 CL40 4800MHz module and other capacities or speeds for this motherboard?

Choose the 2Rx4 CL40 4800MHz module when the board's qualified-vendor list calls for that exact rank, voltage and timing; other capacities or speeds may not be recognised at full performance.

What does the PC5-38400 rating mean once the RDIMM is installed in the H13SSH-E?

PC5-38400 confirms the module runs at DDR5 4800 with a 1.10V supply and CL40 latency, delivering the bandwidth and error-correction the server's memory controller expects.
