4GB DDR3 1600MHz Desktop Module

This 4GB DDR3 DIMM runs at 1600MHz with CL11 timing and 1.5V operation. It is an unbuffered, non-ECC module built as a direct replacement for several ADATA part numbers. The 240-pin form factor fits standard desktop memory slots.

Check motherboard DDR3 support and slot count

Verify that your desktop motherboard accepts DDR3 memory and has an available 240-pin DIMM slot. Confirm the board can run at 1600MHz or will down-clock the module automatically. Ensure the system does not require registered or ECC memory, as this module is neither.

Replaces ADATA AX3U1600W4G9-DB and similar

This module replaces ADATA AX3U1600W4G9-DB, AX3U1600W4G9-DGV, AX3U1600W4G11-DD and AX3U1600GC4G9-1G sticks. The upgrade is worthwhile when your system currently has less than 4GB of DDR3 or when a failed stick needs a matched-specification replacement.

Questions about this item

Does the 240-pin DDR3 module ship with any cables or tools, or must they be purchased separately?

The module is a bare 240-pin DIMM; no cables, screws or tools are included and none are required for installation.

Should I choose the CL11 1.5 V version or a different latency or voltage variant?

This kit is only offered as a single 4 GB stick at CL11 and 1.5 V; no other latency or voltage options exist for this part.

What does the 1600 MHz PC3-12800 rating deliver in a typical desktop?

It runs at 1600 MHz with CL11 timing at standard 1.5 V, giving a peak bandwidth of 12 800 MB/s for everyday multitasking and application loads.
