CrucialRAM 4GB DDR4 2666 MHz CL19 Desktop Memory CT4G4DFS6266

Q: I bought a single 8Gb stick of this for my build - it says 2400 but is running at 1200. Why? Is it only 2400 if I run 2 sticks?

Modern DRAM modules support double data rate (DDR) transfers, meaning that although they function at a given clock speed, they transfer data during both the rise and fall of a CPU clock cycle, allowing for double the data transfers their native speed, or frequency, would suggest. Some diagnostic or system information software does not express this clearly, only reflecting the modules' frequency in megahertz (MHz), making such feedback suggest that your parts are only running at half their possible speed. For example, DDR3-1600 supports 1600 megatransfers per second (MT/s) due to its nature as DDR memory, but runs at 800 MHz.

Q: If I add a 8gb for my Dell i5675 will it be compatible with the 8gb thats already in my pc?

Thank you for contacting Crucial and for your question. The part number that you provided is 100% compatible with your system. That being said, we can guarantee that our memory will work with your computer, but we have no way to guarantee that it will work with what is currently installed in the system. I can tell you that most consumer systems out there can mix different brands of memory without running into any issues.
