 PC Memory RAM Memoria Module Computer Desktop 1GB 2GB PC2 DDR2 4GB DDR3 8GB 667MHZ 800MHZ 1333MHZ 1600MHZ 8GB 1600 RAM DDR2: Used DDR3: New DDR4: new CAS Latency: 667mhz CL555 800mhz CL666 1333mhz = CL9, 1600mhz = CL11, 2133mhz = CL15, 2400mhz = CL17, 2666mhz = CL19 Pinos: DDR2 = 240pin, DDR3 =240pin, DDR4 = 288pin Tensão: DDR2 = 1.8v, DDR3 =1.5v DDR4 = 1.2v 1600 MHz Can Compatible With DDR 3 1333 MHz / 1066 MHz 1333 MHz Can Compatible With DDR 3 1066MHz 800 MHz Can Compatible With DDR 2 667MHz / 533MHz 667 MHz Can Compatible With DDR 2 533/MHz Why is my BIOS or diagnostic program (such as CPU-Z) showing that my memory is running at half the frequency? The BIOS or diagnostic program usually reports the memory bus frequency, 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 800MHz and you are using DDR3-1600 memory, the RAM is running at the correct speed.
