Server Memory Upgrade

This 128GB DDR5 5600 ECC Registered RDIMM is built for Lenovo ThinkAgile VX650 V3, SD650-N V3 and SR680a V3 platforms. It serves administrators who need a single high-capacity module to expand memory in validated server configurations.

Sustained Operation

ECC Registered design with 4Rx4 organisation corrects single-bit errors and buffers address and command signals, helping data integrity during continuous workloads. The JEDEC-standard 1.1V voltage and CL46 latency support stable throughput at the rated 5600 MT/s speed.

Build and Connectors

The 288-pin DDR5 form factor fits the approved ThinkAgile slots without a heat spreader, allowing dense population in supported chassis. Registered buffering means it cannot be mixed with unbuffered or load-reduced modules, so matching memory types is required.

Questions about this item

How much power does the 128 GB DDR5 5600 module draw at 1.1 V?

It runs at the standard DDR5 voltage of 1.1 V, so power draw per DIMM is low and scales with the 5600 MT/s data rate in your Lenovo ThinkAgile VX650 V3.

Which server models accept this 288-pin ECC Registered RDIMM?

Qualified for Lenovo ThinkAgile VX650 V3, SD650-N V3 and SR680a V3; the module is not compatible with standard desktops or unbuffered memory slots.

Can I mix this 4Rx4 registered DIMM with older load-reduced ECC modules?

No — the manufacturer highlights state it cannot be mixed with unbuffered or load-reduced ECC memory, so populate all slots with matching registered DIMMs.
