4GB DDR3L ECC UDIMM for servers

This 4GB DDR3L 1600 ECC UDIMM module targets administrators upgrading or repairing server and workstation systems that require error-correcting unbuffered memory. It serves as a direct replacement for the Crucial CT51272BD160B part number. Systems needing registered DIMMs or higher capacities per slot cannot use this module. Buyers without ECC-capable platforms should look elsewhere.

Low-voltage operation at 1.35V

The DDR3L rating runs at 1.35V, reducing power draw and heat output compared with standard 1.5V DDR3 during normal workloads. CL11 latency at 1600MHz delivers predictable timing for stability-focused deployments. No active cooling is required on the module itself. The unbuffered design keeps the signal path short for compatible platforms.

240-pin DIMM with major-brand chips

A 240-pin DIMM form factor fits standard DDR3 UDIMM slots in supported servers and workstations. The 2Rx8 organisation uses major-brand chipsets under quality-assurance testing for dependable operation. ECC circuitry protects data integrity in memory-intensive tasks. Verify your system's qualified-vendor list before installation to confirm compatibility.

Questions about this item

How do I install this 240-pin DDR3L UDIMM, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify the module is seated evenly; the step often missed is confirming the 1.35V voltage setting in BIOS so the CL11 timings run at the rated 1600 speed.

What maintenance or replacement will this 4GB ECC module need over time?

No scheduled maintenance is required; if a correctable error count rises or the system logs uncorrectable ECC events, replace the module — otherwise it runs for the system's service life.

What limit appears first when this 2Rx8 kit runs sustained workloads?

The 4GB capacity per module fills before bandwidth or thermal limits become a bottleneck, so heavy multitasking or virtualization will hit the size ceiling first.
