4GB DDR3L 1600 Desktop Module

This Crucial CT51264BD160B module provides 4GB of DDR3L memory rated at 1600 MT/s with CL11 latency. It is an unbuffered, non-ECC UDIMM designed for desktop systems. The module operates at a standard voltage of 1.35V. It suits users upgrading older platforms that require DDR3L memory.

240-Pin UDIMM Installation

Installation requires aligning the notch on the 240-pin connector with the motherboard slot key and pressing firmly until the retention clips engage. The dual-voltage design allows operation at 1.35V or 1.5V for broad compatibility. A common issue occurs if the slot is dusty or the module is not fully seated, causing the system to fail POST.

DDR3L Voltage and Speed Limits

The DDR3L standard limits this module to a maximum data rate of 1600 MT/s and a peak bandwidth of PC3L-12800. Operation at 1.35V reduces power draw compared to standard DDR3, but the memory controller must support the lower voltage. Mixing with 1.5V-only modules may force the system to run at the higher voltage.

Questions about this item

How do I verify the module is running at 1600 MT/s with CL11 latency after installation?

Open Task Manager or CPU-Z and confirm the memory tab shows 1600 MHz speed and 11-11-11 timings at 1.35V.

Does the retail package include only the single 4GB UDIMM or are cables and a screwdriver also supplied?

The box contains the 4GB DDR3L UDIMM module only; no cables, tools or extra hardware are included.

Should I choose the 1.35V DDR3L version or a standard 1.5V DDR3 module for my desktop?

Select this 1.35V DDR3L module; it is dual-voltage and will also run at 1.5V if your system requires it.
