Exact-fit server memory

This 384 GB kit contains twelve 32 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 timings at 1.1 V. Registered ECC architecture and 2Rx8 organisation deliver the stability required for fully populated Supermicro H14SST-G systems.

Verify board rules first

Consult the motherboard manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before installing all twelve modules. The 288-pin registered form factor fits only slots designed for RDIMMs.

Suits memory-intensive servers

Ideal for virtualization hosts, database nodes, and compute clusters that need maximum registered ECC capacity on this platform. Not for workstations or desktops that accept only unbuffered UDIMMs, nor for builds requiring SODIMM modules or lower-density kits.

Questions about this item

What comes in the box and is anything else needed to install this kit?

The package contains twelve 32 GB DDR5 4800 CL40 1.1 V 2Rx8 288-pin ECC RDIMM modules for a total of 384 GB. No additional memory parts are required.

Why is this 12-module kit the right choice instead of a smaller or larger set?

The Supermicro H14SST-G motherboard supports twelve DIMM slots; filling all twelve with 32 GB RDIMMs reaches the board's 384 GB maximum while keeping every channel evenly populated.

What does the DDR5 4800 CL40 rating mean once the modules are running in the server?

The memory controller will operate each module at 4800 MT/s with a CAS latency of 40 cycles at 1.1 V, delivering the rated bandwidth and error-correction the platform expects.
