CPU-Z displays only half the RAM speed.
CPU-Z displays only half the RAM speed.
The display shows only half the MHz because it’s a way to simplify the information. CPU-z often shows just the lower half of the MHz value for clarity, making it easier to read. Regarding RAM, it’s a type of memory used by your computer to store data quickly, helping it run faster.
Double data rate isn't relevant to the speed you experience. The MHz value on your RAM indicates a specific configuration, not the actual speed. If your system reports 3200 MHz, it should be 6400 MHz according to DDR standards—not 1600 MHz. This suggests a possible problem with one of your RAM modules. I own four devices at home—two desktops and two laptops—all using DDR4 RAM. My desktop previously showed 3200 MHz but now displays 1600 MHz. In the BIOS it still shows 3200, yet one stick seems faulty. The other devices consistently report 2400 MHz, not 1200. Please disregard the double data rate claim. A 3200 MHz DDR RAM should deliver double that speed, not half. RAM warranties are generally strong, so consider replacing the faulty sticks.
DDR-4 3200 refers to a data rate of 3200 MT/s, not 3200 MHz. A 1600MHz clock results in 3200 Mega Transfers per second, while the CPUZ display shows memory clock speed, not transfer speed.
