4 GB DDR3 1600 module for desktop upgrades

This single Crucial CT51264BA160B module provides 4 GB of DDR3 memory rated at 1600 MHz. It is aimed at owners of older desktop systems that use unbuffered, non-ECC DIMMs and need a straightforward capacity increase. The retail package contains one stick ready for installation in a compatible motherboard slot.

Capacity and headroom: 4 GB suits light workloads

Four gigabytes handles web browsing, office applications and older operating systems without pressure. Modern multitasking with many browser tabs or current games will exceed this amount and force the system to use slower storage for paging. Adding a second identical module would double capacity and enable dual-channel bandwidth if the board supports it.

CL11 latency at 1.50 V defines compatibility

The module runs at CAS latency 11 with a standard 1.50 V supply, matching the DDR3 1600 (PC3 12800) JEDEC profile. Boards that require lower voltage or tighter timings may not recognise the stick or may down-clock it. Verify that your motherboard accepts unbuffered, non-ECC DDR3 at this voltage and latency before purchase.

Questions about this item

Will this DDR3 1600 module down-clock to match my existing slower DDR3 sticks?

Yes, the module will run at the speed of the slowest installed DDR3 memory, so it operates reliably alongside older modules.

How can I confirm the CT51264BA160B is running at 1600 MHz with CL11 after installation?

Open Task Manager or CPU-Z and verify the memory tab shows 1600 MHz speed and CAS latency 11.

Does the retail package include only the 4 GB stick or are cables or a heat spreader also supplied?

The retail box contains the single 4 GB unbuffered DIMM; no heat spreader, cables or additional accessories are included.
