DDR4 4GB RAM – Overview

Type: DDR4 SDRAM (Double Data Rate 4th Generation)
Capacity: 4GB
Speed: Typically ranges from 2133 MHz to 3200 MHz (commonly 2400 MHz or 2666 MHz)
Form Factor:

• DIMM – for desktops

• SO-DIMM – for laptops and compact systems
  Voltage: 1.2V (lower than DDR3, which uses 1.5V)
  Latency: CL15 to CL19 (varies by model)
  Pins:

• 288-pin (DIMM)

• 260-pin (SO-DIMM)

Key Features:

• Improved performance and higher bandwidth over DDR3

• Lower power consumption – ideal for energy-efficient systems

• Increased memory density – supports larger and faster memory modules

• Reliable and stable – often features ECC (Error Correcting Code) in server versions

Use Cases:

• Entry-level desktops or laptops

• Office productivity (web browsing, word processing, spreadsheets)

• Lightweight media usage

• Basic gaming (with integrated graphics or low-end GPUs)
