Fast speed: The frequency speed DDR4 memory transfer speed and CPU data exchange is faster, and can support operating system multi-threaded operation. Multi-tasking, large games run smoothly, giving you a no-delay and jet-like experience.Overclocking: Built-in Intel XMP2.0 version, easy to experience the high-speed pleasure of the hyperband, say goodbye to CatonLow fever: 1.2V working voltage, lower power consumption, keep working at low temperature, and run more stable.Low power consumption: BR-DDR4 memory is faster and saves power. The operating voltage is reduced from DDR 1.5V to DDR4 1.2V, saving 20%.Hard disk/flash memory vendors are using decimal arithmetic: 1MB=1000KB, 1G=1000MB calculated, but the operating system is using binary arithmetic: 1MB=1024KB, 1GB=1024MB. So there are some differences between display capacity and nominal capacity of hard disk/flash memory products.Transmission bandwidth:PC19200Capacity: 4GBFrequency: 2666MHzFunction: DDR4 260PIN 64bitWorking temperature: 0-85 CelsiusScope of application: DesktopColour: blackMaterial: PCBSize: 13.5*3cmPackage Contents:1 * RAM MemoryOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
