4GB DDR3 1066 ECC RDIMM Server Module

This 4GB DDR3 1066 ECC RDIMM module delivers registered error-correcting memory for server and workstation platforms. It operates at PC3-8500 speed with a CL7 latency and standard 1.5V voltage. The 4Rx8 organisation suits systems that require registered DIMMs for stability under sustained workloads.

Direct Replacement for IBM-Lenovo Part Numbers

The module matches the specifications of IBM-Lenovo part numbers 43X5055, 46C7444, 46C7448, 46C7452, 46U2941 and 67Y0125. It upgrades installations that currently run lower-capacity or non-ECC DDR3 DIMMs at the same 1066 MHz rate. The jump is worthwhile when the platform supports registered ECC memory and the workload demands data integrity over raw bandwidth.

240-Pin DIMM Form Factor for Registered Slots

The 240-pin DIMM fits DDR3 registered memory slots that accept 1.5V ECC RDIMMs. It requires a motherboard and chipset qualified for registered operation and will not function in unbuffered desktop slots. The single-module design leaves additional slots free for further capacity expansion within the system's supported limits.

Questions about this item

Will the 240-pin DDR3 DIMM fit my server's registered memory slots?

Yes, the module uses the standard 240-pin DDR3 DIMM form factor with registered (RDIMM) signalling, matching server boards that accept PC3-8500 ECC registered memory.

Do I need to populate specific slots or follow a rank order when installing this 4Rx8 module?

Install the RDIMM in the slot sequence recommended by your server manual; a common mistake is mixing 4Rx8 ranks with different rank configurations in the same channel, which can prevent the system from posting.

How do I know when this ECC RDIMM should be replaced?

Run periodic memory diagnostics; if corrected ECC error counts rise steadily or the module fails a full test pass, replace it to maintain data integrity.
