Capacity and Compatibility

This kit provides 512GB of DDR4 ECC registered memory in four 128GB modules. It is built for the Lenovo ThinkEdge SE450 Edge AI Server and will not fit systems that require unbuffered DIMMs or a different pin count.

Installation Requirements

Verify that the server has four free 288-pin DDR4 RDIMM slots and that the BIOS supports 4Rx4 registered modules at 3200MHz. The kit runs at 1.2V, so the platform must supply that voltage for stable operation.

What the Kit Changes

Adding the full 512GB kit expands the memory ceiling for virtualization and edge-AI workloads while ECC and registered signalling protect data integrity. No heat spreaders are included, so airflow in the chassis must be sufficient for bare modules.

Questions about this item

Does the 512GB kit include all four 128GB modules or must any be purchased separately?

The kit contains four 128GB DDR4 3200 CL22 ECC RDIMM modules for a total of 512GB; nothing else is required for installation.

When should I choose the 4Rx4 128GB modules over other capacities for the ThinkEdge SE450?

Select this 4Rx4 128GB configuration when the SE450 memory slots support quad-rank modules and the workload needs maximum density per slot.

What does the 3200 CL22 rating mean once the memory is running in the SE450?

The modules operate at 3200 MT/s with a CAS latency of 22 cycles at 1.2 V, delivering PC4-25600 bandwidth in the server.
