4GB DDR3 1600MHz Desktop Upgrade

This single 4GB DDR3 module runs at 1600MHz with PC3-12800 bandwidth and CL11 latency. It is built as a non-ECC unbuffered DIMM using major-brand chips and operates at the standard 1.5V for desktop systems. The module targets users upgrading older AMD or Intel platforms that accept DDR3 memory.

Check DDR3 slot and voltage before ordering

Verify that your motherboard has an available 240-pin DDR3 slot and supports 1.5V unbuffered non-ECC modules at 1600MHz. Consult the system manual or vendor specifications to confirm the maximum capacity per slot and the total memory limit for your platform. Matching the existing module speed and voltage avoids instability.

240-pin DIMM with major-brand chips

The 240-pin gold-edge connector seats firmly in standard desktop DDR3 sockets and the low-profile green PCB fits most chassis without clearance issues. Major-brand chips are tested for reliability under continuous workloads. The module carries a lifetime warranty and includes access to US-based technical support for installation questions.

Questions about this item

Will this module fit a Dell desktop that originally used part A5649222?

Yes, the module is listed as a compatible replacement for Dell part numbers A5649222, A5764362, A6994459, A7398800, A7545689 and SNP531R8C/4G.

My motherboard has 240-pin DDR3 slots — is the voltage correct?

The module runs at the standard DDR3 voltage of 1.5 V, matching the 1.50 V specification for 240-pin DIMM slots.

Can I add this stick alongside existing CL11 memory without timing conflicts?

The module uses CL11 latency at 1600 MHz, so it will match other PC3-12800 CL11 sticks; the system will run all modules at the slowest common settings.
