  • 64 GB DDR5 capacity expands server memory headroom for virtualization workloads
  • 4800 MHz PC5-38400 speed matches the motherboard's rated data rate for full throughput
  • Registered ECC architecture offloads the controller and corrects single-bit errors to prevent silent data corruption
  • 2Rx4 dual-rank organization enables full-slot population at maximum density
  • 1 V DDR5 operating voltage reduces power draw per module in dense configurations

Server-ready DDR5 upgrade

This 64 GB DDR5-4800 RDIMM is built for the Supermicro H14DSG-OM motherboard. It delivers registered ECC memory that the platform's controller expects at full rated speed and capacity.

288-pin registered form factor

The module uses the 288-pin RDIMM layout this board requires, not UDIMM or SODIMM. Registered buffering offloads the memory controller so every slot can run fully populated while ECC corrects single-bit errors on the fly.

CL40 timing at 1.1 V

CAS latency 40 and 1.1 V operation match the exact timing and voltage the server's memory controller specifies. Buyers needing a different rank configuration, voltage, or latency should verify their manual before ordering.

Questions about this item

Does the DDR5 4800 interface run at the full PC5-38400 rate on this motherboard?

The module is spec-matched to the Supermicro H14DSG-OM so the memory controller recognises the 64 GB 2Rx4 Registered ECC DIMM at its rated DDR5 4800 speed.

What physical slot and form factor does this 288-pin RDIMM require?

It needs a standard 288-pin DDR5 RDIMM slot on the Supermicro H14DSG-OM; UDIMM or SODIMM slots will not accept the registered form factor.

What is the correct population order when installing this kit on the H14DSG-OM?

Consult the motherboard manual for the approved DIMM population sequence; installing modules in the wrong order is the most common reason the system fails to recognise full capacity.
