4GB DDR3L 1600 ECC RDIMM for servers

This A-Tech module provides 4 GB of DDR3L memory at 1600 MHz with CL11 latency. It operates at 1.35 V and uses a registered ECC design with a single 1Rx4 rank. The 240-pin DIMM fits compatible server and workstation motherboards requiring DDR3L registered memory.

Suited for Lenovo system upgrades and ECC repair

The module serves as a direct replacement for IBM-Lenovo part numbers 00D5023, 00D5024 and 46W0684. Builders who need higher capacity per slot, different voltage levels, unbuffered memory or non-ECC operation should look at alternative modules.

Registered ECC with 1Rx4 organisation

The registered buffer and ECC function combine with the 1Rx4 rank layout to meet the strict signal-integrity demands of supported server platforms. Systems that require unbuffered DIMMs or a different rank configuration will not accept this module.

Questions about this item

How do I install this 240-pin DDR3L RDIMM and what step do people get wrong?

Align the notch with the slot key, press firmly until both clips snap shut, and verify the system posts with ECC registered memory enabled in BIOS.

What maintenance or replacement will this 4GB 1Rx4 module need later?

No routine maintenance is required; replace only if memory diagnostics report correctable ECC errors that exceed the platform threshold.

What limit shows up first under sustained use with this 1.35V CL11 kit?

The registered buffer adds one cycle of latency, so sustained throughput is capped by the DDR3L 1600 MT/s data rate rather than thermals.
