Server ECC RDIMM upgrade

This 8 GB DDR3 1333 registered ECC module is built for Lenovo ThinkServer RD230, RD240 and TD200x systems. It replaces a long list of Lenovo part numbers including 46C0542, 46C7449 and 49Y1436. The single 240-pin DIMM runs at PC3-10600 with CL9 latency at 1.5 V. It is not compatible with standard desktop computers or unbuffered memory.

Sustained load behaviour

Registered buffering and ECC correction keep data integrity intact during continuous server workloads. The 2Rx4 organisation spreads accesses across two ranks for steadier throughput. JEDEC-compliant 1.5 V operation avoids voltage drift over long uptime. No heat spreader is fitted, so airflow in the server chassis handles cooling.

Pre-order checklist

Verify your ThinkServer model is RD230, RD240 or TD200x before ordering. Confirm the motherboard accepts registered ECC RDIMMs and does not require unbuffered modules. Match capacity, speed and voltage across all populated slots for optimal performance. Ensure the 240-pin DDR3 form factor matches the memory slots in your chassis.

Preguntas sobre este artículo

How much power does this 1.5 V DDR3 ECC RDIMM draw when the server runs 24/7?

At the rated 1.5 V the module follows standard DDR3 1333 power envelopes; actual draw depends on the ThinkServer platform and workload.

What must the Lenovo ThinkServer already have for this 2Rx4 registered DIMM to work?

The board must support DDR3 1333 ECC registered memory and provide a 240-pin RDIMM slot; unbuffered DIMMs cannot be mixed with this module.

Can I add this CL9 8 GB stick alongside older DDR3 1333 modules already in my RD230?

Yes, if the existing modules are also ECC registered at 1333 MT/s; mixing ranks or speeds may force the channel to the slowest common timing.
