512GB DDR5 4800 ECC RDIMM kit for Lenovo

This kit provides 512GB of DDR5 memory across four 128GB registered DIMMs. It is built for the Lenovo Thinkstation PX workstation platform where ECC and registered operation are required. The modules run at 4800MT/s with a CL40 latency at 1.1V.

Four matched 128GB modules simplify full population

The package contains four identical 288-pin RDIMMs in a single kit, removing the need to source and match individual sticks. Each module uses a 4Rx4 organisation with ECC and registered buffering, so the workstation sees a consistent, validated configuration across all slots.

Handles large in-memory workloads.

The 512GB capacity supports multi-VM hosting, large dataset analytics and high-core-count rendering without swapping. Workloads that demand higher memory bandwidth or lower latency than DDR5 4800 CL40 provides will not benefit from this kit.

Points forts

Questions sur cet article

Will the 128 GB modules need any firmware updates or active cooling as they age?

These registered ECC modules have no heat spreader and run at the standard 1.1 V; they rely on the workstation's airflow and require no firmware maintenance.

What limits sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

The DDR5 4800 MT/s clock sets the peak bandwidth ceiling; CL40 latency determines access delay but does not cap maximum throughput.

How much heat and noise do the four 4Rx4 RDIMMs add when the ThinkStation PX runs all day?

Operating at 1.1 V with no onboard fans, the modules add minimal heat; any audible noise comes from the chassis fans responding to total system load.
