Exact-Match DDR5 Kit for Supermicro H14DSH

This 192GB kit delivers twelve 16GB DDR5-4800 Registered ECC RDIMMs built to the memory controller's exact rank, voltage and timing requirements. It targets administrators upgrading a Supermicro H14DSH motherboard to full population without guesswork.

Registered Architecture Offloads the Controller

Each 288-pin RDIMM runs at 1.1V with CL40 latency and 1Rx8 organisation, allowing every slot to operate at rated speed when fully populated. The registered design reduces electrical load on the memory controller, while on-die ECC corrects single-bit errors before they affect production workloads.

Twelve Modules Ship Ready for Population

The package contains the complete 12x16GB set matched to the board's population rules, so no additional DIMMs or mixed-capacity planning are required. Installers should still consult the motherboard manual for approved slot order and BIOS steps before seating the modules.

Questions about this item

What is the CAS latency that limits throughput under sustained load?

CL40 timing sets the minimum access delay the memory controller must wait for on every read cycle during continuous operation.

How much power does the 12-module kit draw at the rated 1.10 V?

Each 16 GB RDIMM operates at 1.10 V; total draw depends on the server's memory controller and population rules, so consult the H14DSH manual for exact figures.

What motherboard and form factor must I already have for this kit to work?

A Supermicro H14DSH motherboard with 12 available 288-pin DDR5 RDIMM slots is required for full installation.
