4GB DDR3 ECC RDIMM for servers

This 4GB DDR3-1333 ECC registered DIMM is built for servers and workstations that require error-correcting memory. It operates at 1333 MHz with CL9 latency and standard 1.5V power. The module uses a 2Rx8 organisation and major-brand chips for dependable operation in compatible IBM-Lenovo systems.

Registered design and standard voltage

Registered buffering reduces electrical load on the memory controller, helping stability in multi-DIMM configurations. The 1.5V DDR3 standard voltage keeps power draw predictable without requiring special cooling. ECC functionality detects and corrects single-bit errors to protect data integrity during continuous workloads.

240-pin DIMM fits registered slots

The 240-pin form factor installs only in motherboards that support DDR3 registered ECC memory. Verify your system's qualified vendor list against the listed IBM-Lenovo part numbers before purchase. This single module leaves remaining slots free for additional capacity upgrades when the platform allows.

Questions about this item

How do I install this 240-pin DDR3 RDIMM and what step is often missed?

Power off the server, open the chassis, align the module key with the slot notch, press firmly until both retention clips lock, then verify in BIOS that the 4GB ECC registered module is detected at 1333MHz.

What maintenance or replacement will this 1.5V registered DIMM need over time?

No routine maintenance is required; if a memory error appears in system logs, reseat or replace the module, otherwise it runs for the server's service life.

What limit appears first when this CL9 2Rx8 module runs under sustained load?

The DDR3-1333 bandwidth ceiling and registered-buffer latency are the first constraints during continuous heavy workloads.
