(double data rate) the data rate provides twice the frequency of the memory bus. So if the memory bus speed is 800mhz and you are using -1600 memory, the ram is running at the correct speed.Adopt high-quality IC particles and pa strict testing to ensure high stability and bility, which is a powerful tool to improve efficiency and easily achieve work objectivesBlack Diamond s Quality AuranceDesigned with 8 layers of black diamond board, new frosted black anti-solder layer, with anti-interference, anti-static performance, gold fingers using high-strength gold plating proce, wear resistance, anti-oxidation is stronger, and has a better electrical conductivity, to ensure the stability of data nsmiionHigh speed and stability Excellent compatibilityHigh quality memory selection and advanced technology to ensure compatibility with mainstream brand computers, support various operating syst and ensure long and stable system operationTechnically sound and powerfulProfeional memory technology and comprehensive memory solutions, offering targeted memory timing settings and a wider range of CL programmability to meet individuaamer needsQuick response game, easy to deal with in the officeEasily upgrade your computer to support large games runs,Stable improvement of computer operating efficiencyHigher frequency Significant speed sHigh frequency speed memory nsfer and CPU data exchange more quickly, and good support for operating system multi-threaded operation, multi-tasking operations, large games run smoothly, bringing zero latency and fast experience1. brand with box2.
