64GB DDR5 4800 ECC RDIMM
This 64GB DDR5 module operates at 4800MHz with ECC and registered buffering for server and workstation platforms. It replaces Hynix part numbers HMCG94AEBRA103N, HMCG94AEBRA108N, HMCG94AEBRA123N, HMCG94MEBRA102N and HMCG94MEBRA103N. The 2Rx4 organisation and 1.10V voltage match the original specifications. Systems requiring unbuffered memory or non-ECC operation cannot use this module.
288-pin RDIMM build and daily handling
The module uses a standard 288-pin DDR5 RDIMM form factor without a heat spreader, relying on chassis airflow for cooling. Registered signalling reduces electrical load on the memory controller, which is essential for multi-module configurations in dense servers. Installers must follow the system manual for correct slot population and channel guidelines to ensure stability. Buyers who need a low-profile heat spreader for restricted clearance should look elsewhere.
DDR5 4800 interface limits
The DDR5 4800 interface delivers a peak transfer rate of PC5-38400 with a CAS latency of 40. Bandwidth and latency are fixed by the JEDEC standard for this speed grade; higher throughput requires platform support for faster DDR5 speeds. ECC correction adds reliability for critical workloads but does not increase raw bandwidth. Systems limited to lower DDR5 data rates will downclock the module automatically.

この商品に関する質問
Does the DDR5-4800 PC5-38400 interface cap real-world throughput to the module's rated speed?
The module runs at DDR5 4800 MT/s with PC5-38400 bandwidth; actual throughput depends on the server platform, memory controller, and channel configuration.
What physical slot and clearance does the 288-pin DDR5 RDIMM need to fit?
It requires a standard 288-pin DDR5 DIMM slot; the module has no heat spreader, so it fits in tight server chassis with minimal vertical clearance.
How is the ECC RDIMM installed, and what step do people often get wrong?
Align the key notch with the slot, press firmly until both retention clips click, and follow the system manual for correct channel population — mixing registered and unbuffered DIMMs is the common error.
