2GB DDR3 1600 desktop module

This Crucial CT25664BA160B module provides 2GB of DDR3 memory rated at 1600 MHz with a CAS latency of CL11. It operates at 1.50 V and is an unbuffered, non-ECC DIMM. The green PCB is sold as part of a dual-channel kit for desktop systems.

DDR3 1600 bandwidth and latency limits

The DDR3 1600 standard delivers up to 12.8 Gbps bandwidth per channel at this speed grade. CAS latency of 11 cycles at 1600 MHz sets the minimum access delay for random reads and writes. Systems that only support lower DDR3 speeds will run the module at the highest common frequency instead.

2GB capacity decides fit

A single 2GB DIMM suits older desktops that have two or four slots and a modest maximum memory limit. Builders who need more storage per module or a higher total capacity for modern workloads should choose larger modules instead.
