4GB DDR3 1600 Desktop DIMM

This 4GB DDR3 1600 module is a 240-pin unbuffered DIMM built for desktop computers. It runs at the standard 1.5V voltage and carries a PC3-12800 rating. The single stick is designed as a direct replacement for specific Samsung part numbers.

Suits AMD and Intel desktop upgrades.

The module is non-ECC and unbuffered, matching mainstream AMD and Intel desktop platforms that accept standard UDIMMs. Systems requiring ECC or registered memory cannot use this part. Buyers needing capacities beyond 4GB should look at larger modules or multi-stick kits.

DDR3 1600 speed at 1.5V decides fit

The decisive specification is the DDR3 1600 (PC3-12800) speed combined with 1.5V operation. Your motherboard and CPU must support DDR3 at this frequency and voltage; otherwise the module will not function. Verify the platform’s supported memory standard before ordering.
