8 GB DDR3L ECC module for server workloads

This Crucial CT102472BD160B is an 8 GB unbuffered DDR3L UDIMM running at 1600 MT/s with CL11 latency. It operates at 1.35 V and includes ECC error correction for data integrity. The 240-pin layout follows the standard UDIMM form factor for compatible server platforms.

Low-voltage operation reduces heat and power draw

At 1.35 V the module draws less power than standard 1.5 V DDR3, lowering thermal output in dense configurations. Unbuffered design adds no register delay, keeping latency tight for typical workloads. No heat spreader is fitted, so airflow across the PCB handles cooling directly.

Replaces non-ECC or lower-capacity DDR3 UDIMMs

The jump is worth it when your platform supports unbuffered ECC and you need single-bit error correction without registered modules. It does not suit systems requiring registered DIMMs or higher-density 16 GB sticks. Builders needing more than 8 GB per slot should look elsewhere.

Questions about this item

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

Align the notch on the module with the slot key, press firmly until both retention clips snap shut, then verify the system detects the full 8GB at 1600 MT/s in BIOS.

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

No routine maintenance is required; replace only if memory diagnostics report uncorrectable errors or if a system upgrade demands higher capacity or a newer DDR generation.

What limit appears first when this 1.35 V CL11 kit runs sustained workloads?

The DDR3L 1600 CL11 timing ceiling caps throughput at 12800 MB/s, so bandwidth saturates before the 1.35 V thermal envelope becomes a constraint.
