Memory Channel:Dual Channel CAS Latency: 2133MHZ=CL15 2400MHZ=CL17 2666MHZ=CL19 3200MHZ=CL22 Pins: DDR4=260pin Voltage: DDR4=1.2V Features:Unbuffered Function:Non-ECC Warranty: lifetime Why is my diagnostic program (CPU-Z etc.) showing that my memory is running at half the frequency? CPU-Z usually detects the bus frequency of the memory, which is half of the frequency for DDR type memory. DDR (Double Data Rate) data rate provides twice the memory bus frequency. Therefore, if the memory bus speed is 1200MHz and you are using DDR3-2400 memory, the RAM is running at the correct speed. Chip Brand: HY/SK/SEC/CRUCLAL1.
