A-Tech 4GB DDR3 1600 CL11 1.5V Desktop Memory

Compatible DDR3 1600 Replacement

This A-Tech 4 GB DDR3 1600 module replaces ADATA AX3U1600W4G11-BR and AX3U1600W4G11-RD parts in desktop computers. It runs at PC3-12800 speed with CL11 latency and standard 1.5 V operation. The unbuffered non-ECC DIMM fits 240-pin desktop slots. It offers a straightforward capacity boost for older systems.

Speed and Latency Match

The decisive specification is the tested 1600 MHz frequency combined with CL11 timing at 1.50 V. Your motherboard must support DDR3 1600 at this voltage and latency for the module to run at its rated speed. If the board only runs lower frequencies the memory will downclock automatically.

Simple DIMM Installation

Installation requires aligning the notch on the 240-pin DIMM with the slot key and pressing firmly until the retention clips click. The most common issue is the module not seating fully, which causes a no-post condition. Reseating usually resolves this immediately.
