Exact-match server upgrade

This 64 GB DDR5-4800 Registered ECC RDIMM is built for the Supermicro H14DSG-O-CPU motherboard. Its 2Rx4 organisation, 1.1 V operation and CL40 timing match the board's memory-controller expectations so the full capacity is recognised at rated speed.

DDR5 RDIMM population rules

Registered architecture buffers the address and command bus, allowing every slot to run fully populated without overloading the controller. ECC corrects single-bit errors on the fly, preventing silent data corruption. The motherboard manual defines supported capacities, approved population order and installation steps that must be followed before purchase.

288-pin registered form factor

The module uses the 288-pin RDIMM form factor required by this platform; it is not a UDIMM or SODIMM and will not fit those slots. No heat spreader is fitted, so airflow across the chips depends on the server's chassis design. Major-brand Samsung, Micron or Hynix DRAM ensures consistent enterprise-grade reliability.

Questions about this item

Should I pick the 64 GB DDR5 4800 CL40 2Rx4 module or a different capacity for the Supermicro H14DSG-O-CPU?

The 64 GB 2Rx4 Registered ECC RDIMM matches the board's qualified DIMM population rules; choose another capacity only if your manual lists it for the same slot layout.

What does the 4800 MT/s rating deliver once the module is installed in the server?

The memory controller will run the DIMM at its rated 4800 MT/s with CL40 timing at 1.10 V, giving the full PC5-38400 bandwidth the platform expects.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered buffer reduces electrical load on the controller so all slots can be populated at 4800 MT/s, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
