Exact-match DDR5 kit for Supermicro H14SSF

This 512GB kit contains four 128GB DDR5 4800 RDIMM modules rated at 1.10V and CL40. Registered ECC architecture with 2Rx4 organisation meets the precise rank, voltage and timing the server memory controller expects for full-capacity operation. Designed for administrators upgrading a Supermicro H14SSF platform with enterprise-grade stability.

Verify DIMM population rules before ordering

Consult the system or motherboard manual for supported capacities, approved slot order and installation steps. The 288-pin Registered form factor is required; UDIMM or SODIMM modules will not fit. Chipset components come from major OEM sources such as Samsung, Micron or Hynix depending on supply. No heat spreader is included on these modules.

Sustained-load behaviour with registered ECC

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed during continuous workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production environments. Modules operate at the standard 1.1V DDR5 voltage without additional cooling requirements. Lifetime replacement warranty and US-based technical support back the kit.

Questions about this item

What is included in the kit and what must be purchased separately?

The kit contains four 128 GB DDR5 4800 CL40 1.1 V 2Rx4 ECC registered RDIMMs for a total of 512 GB. No additional modules, cables or cooling are required for installation.

How do I decide between this 512 GB kit and a smaller capacity for my Supermicro H14SSF?

Choose this 4 x 128 GB kit when the motherboard manual confirms support for 128 GB RDIMMs in all populated slots and you need the maximum registered ECC capacity at DDR5 4800.

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

The modules will operate at 4800 MT/s with a CAS latency of 40 cycles at 1.1 V, delivering PC5 38400 bandwidth per module while registered ECC maintains data integrity under full load.
