Server ECC RDIMM Upgrade

This OWC module provides 8 GB of DDR3 ECC registered memory for workstations, servers, NAS systems and routers. It runs at 1600 MHz with CL11 latency and a 1.5 V supply. The single-rank 1Rx4 organisation uses 240-pin RDIMM form factor without a heat spreader.

Replaces Lenovo 03X4325

The part matches the exact specifications of Lenovo part number 03X4325 for direct replacement. It upgrades systems currently running lower-capacity or slower DDR3 registered DIMMs. The jump is worth it when ECC error correction and registered buffering are required for data integrity.

Build Integration Notes

This memory fits 240-pin DDR3 slots that support registered ECC operation. It cannot be mixed with unbuffered modules and will not work in standard desktop platforms. JEDEC and RoHS compliance ensures warranty-safe installation in qualified server chassis.

Perguntas sobre este artigo

Will this 240-pin DDR3 ECC Registered RDIMM fit a standard server DIMM slot?

Yes — the module uses the industry-standard 240-pin DDR3 form factor and 1.5 V operation required by registered server slots.

What is the correct installation step for this 1Rx4 CL11 registered module that builders often miss?

Align the key notch with the slot, press straight down until both retention clips click, and never mix this registered DIMM with unbuffered memory.

When should the 8 GB DDR3 1600 module be replaced in a 24/7 server?

Replace it if ECC correctable-error counts rise steadily, the system logs uncorrectable memory errors, or the module fails a full memory diagnostic pass.
