64GB DDR5-4800 ECC RDIMM for Servers

This 64GB registered DIMM is built for server and workstation platforms that require error-correcting memory. It operates at the standard DDR5-4800 speed with a CAS latency of 40 and runs at 1.10V. The module targets administrators upgrading compatible IBM-Lenovo systems or similar enterprise hardware.

288-pin registered build without heat spreader

The module uses a 288-pin DDR5 RDIMM form factor and a 2Rx4 rank configuration with major-brand DRAM ICs. Registered buffering reduces electrical load on the memory controller, supporting stability in multi-DIMM configurations. The absence of a heat spreader keeps the profile low for dense chassis but relies on system airflow for cooling.

DDR5-4800 bandwidth ceiling

The PC5-38400 rating sets the maximum data rate for this module, limiting throughput to the DDR5-4800 specification. Registered operation adds a clock cycle of latency versus unbuffered memory, which affects timing-sensitive workloads. Compatibility depends on the platform's qualified-vendor list; systems not validated for this part number may not POST or may run at reduced speeds.

Preguntas sobre este artículo

Does the DDR5-4800 (PC5-38400) rating set a hard ceiling on memory bandwidth for this module?

The module is rated DDR5-4800 (PC5-38400). The memory controller and channel population in your server determine the sustained bandwidth you will see.

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

It fits a standard 288-pin DDR5 RDIMM socket. No heat spreader is present, so low-profile heatsinks or tight DIMM spacing will not interfere.

What is the correct installation sequence for this 2Rx4 registered ECC module?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the key in the slot, press firmly until both retention clips latch, then follow the system manual for channel population order.
