128 GB DDR4 LRDIMM for Cisco M5 Servers

This 128 GB DDR4 2933 CL21 4Rx4 288-pin ECC Load Reduced DIMM is built for Cisco HX220c M5, HX240c M5, HXAF220c M5, HX-E-220M5SX and C480 ML M5 servers. It targets administrators who need maximum capacity per slot in qualified enterprise platforms.

Load-Reduced ECC architecture prevents mixing

The module uses 4Rx4 Load-Reduced ECC technology that is electrically incompatible with standard unbuffered or registered ECC DIMMs. Systems must support LRDIMM topology; desktop and consumer workstation boards cannot use this memory.

Operates at 1.2 V with JEDEC-standard thermal

No heat spreader is fitted; the module relies on server chassis airflow for cooling. Power draw follows the 1.2 V DDR4 specification at 2933 MT/s, with backward compatibility at 2133, 2400 and 2666 MT/s when the platform requires lower speeds.

Perguntas sobre este artigo

What does the 128 GB capacity mean for a Cisco HX220c M5 server?

A single module adds 128 GB of ECC load-reduced memory, increasing total system capacity without occupying additional DIMM slots.

How does the PC4-23400 rating affect real-world speed in a Cisco C480 ML M5?

The module runs at DDR4 2933 CL21; the system will operate it at the highest speed the platform and memory controller support, down to 2133 MHz if required.

What physical slot and clearance does the 288-pin LRDIMM need in a Cisco HX240c M5?

It fits a standard 288-pin DDR4 DIMM socket; the module has no heat spreader, so it clears standard server heatsinks and airflow baffles.
