Exact-match server upgrade

This 128GB DDR5-4800 module is built as a direct drop-in for the Supermicro H13SVW-N motherboard. It uses the registered RDIMM form factor, 2Rx4 rank structure and 1.1V operation that the board's memory controller expects.

Enterprise stability focus

Buyers who need registered ECC memory for fully populated servers will find the correct specifications here. Those requiring unbuffered UDIMMs, SODIMMs, or non-ECC modules for workstations should look at a different product line.

Single-module kit contents

The package delivers one 288-pin DDR5 RDIMM rated at PC5-38400 with CL40 latency. No heat spreader, additional cables or software utilities are included, so installation depends entirely on the motherboard's documented population rules.

Questions about this item

Does my Supermicro H13SVW-N motherboard need to support 2Rx4 registered ECC DDR5 at 1.1V for this 128GB module to work?

Yes, the H13SVW-N must accept 288-pin RDIMMs with 2Rx4 organisation, 1.1V operation and registered ECC; the module matches those exact specifications so the board will recognise the full 128GB capacity at DDR5-4800 CL40.

Can I mix this 128GB DDR5-4800 CL40 RDIMM with slower DDR5 modules already installed in my H13SVW-N?

The motherboard will down-clock all populated slots to the speed of the slowest module, so existing slower DDR5 will force this kit to run below its rated 4800 MT/s and may require looser timings than CL40.

How can I verify the module is running at DDR5-4800 with CL40 and ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory frequency shows 4800 MT/s, CAS latency reads 40, voltage reports 1.1V and ECC status is enabled for the installed 128GB RDIMM.
