8GB DDR3 1333MHz ECC RDIMM for IBM-Lenovo Servers

This 8GB registered DIMM is built for server and workstation systems that require ECC memory. It replaces IBM-Lenovo part numbers 47J0152 and 49Y1441 with a compatible A-Tech module. The module runs at DDR3 1333MHz with a CL9 latency and standard 1.5V operation. It targets administrators upgrading compatible IBM-Lenovo platforms.

Registered 2Rx4 Design Upgrades Non-ECC

The 2Rx4 registered layout adds a register buffer that reduces electrical load on the memory controller, allowing higher densities per channel. It upgrades systems currently using non-ECC unbuffered DIMMs or smaller registered modules that lack error correction. The jump is worth it when data integrity and maximum slot population matter for the workload. Buyers needing unbuffered desktop memory or non-ECC laptop SO-DIMMs cannot use this module.

Sustained Load Stability Through ECC

Under continuous operation the ECC function detects and corrects single-bit errors before they affect applications. The registered signal buffering keeps timing margins stable across all populated slots during extended workloads. Quality assurance testing validates reliability for 24/7 server duty cycles. The standard 1.5V DDR3 voltage maintains consistent power draw without the spikes seen in overclocked consumer memory.

Questions about this item

Does the 240-pin DDR3 DIMM fit a standard server memory slot?

Yes, the module uses the 240-pin DDR3 DIMM form factor that matches standard registered server slots.

What is the correct seating procedure for this 2Rx4 registered ECC module?

Align the notch with the slot key, press firmly until both retention clips click, and verify the module sits level.

When should the 1.5 V DDR3 ECC RDIMM be replaced?

Replace it if memory diagnostics report uncorrectable ECC errors or the system fails to recognise the 8 GB capacity.
