A-Tech 4GB DDR3 1333MHz Desktop RAM

This A-Tech module provides 4GB of DDR3 memory for desktop computers. It operates at 1333MHz with a PC3-10600 rating and uses a standard 240-pin DIMM form factor. The kit is designed as a compatible replacement for several Crucial part numbers including CT51264BA1339 and BLS4G3D1339DS1S00.

DDR3 1333MHz PC3-10600 interface limits

The module runs at the standard DDR3 voltage of 1.50V with CL9 latency timings. As an unbuffered non-ECC DIMM, it fits consumer desktop platforms that support this specific speed grade. Systems limited to lower DDR3 frequencies will typically downclock the module automatically to match the memory controller capabilities.

Straightforward 240-pin DIMM installation

Installing this memory involves aligning the notch on the module with the key in the motherboard slot and pressing firmly until the retention clips engage. The most common issue occurs when the notch position is mismatched, which prevents the module from seating fully and can cause the system to fail to boot or recognise the new memory.
