  • Why does CPU-Z (Memory tab) show half the frequency speed of my memory kit?

    CPU-Z reports the operating frequency of the DRAM. Since DDR (DOUBLE Data Rate) memory transfers data on both the rising and falling edges of the clock signal, the actual clock speed is half of the advertised effective speed. CPU-Z shows the actual clock speed.

     

    For example, if your DDR3 memory is rated at 1600 MHz, CPU-Z will show 800 MHz, as the effective rate is 800 MHz × 2 = 1600 MHz.

  • How do l determine if my RAM is defective?

    You can use memory testing tools such as Memtest86 or Windows Memory Diagnostic tool to determine if your RAM is causing any issues. It’s recommended to test your memory independently from the operating system to eliminate the possibility of drivers or other software causing the errors. If the tools show errors, then the memory might have developed a fault, please contact our tech support for further assistance and we will do our best to help you (support@biwintech.com).
