Important Compatibility Notice: Check Before You Buy: This RAM is designed for specific systems. To ensure compatibility, please verify your computer's specifications (CPU, motherboard, and existing RAM type) before purchasing. If your system's specs do not match this product's requirements (DDR2, 240-pin, for AMD platforms), it will not work correctly. How to Check Your Computer's Max Supported RAM: 1. Press the Windows key and R key together to open the "Run" dialog box. 2. Type "cmd" and press Enter to open the Command Prompt. 3. Type "wmic memphysical get maxcapacity" and press Enter. 4. You will see a number representing the maximum memory capacity in kilobytes (KB). You can convert this to gigabytes (GB) by dividing the number by 1024 twice (e.g., 4194304 KB / 1024 / 1024 = 4 GB).
