Dell 8GB PC3-14900 DDR3 1866MHZ Registered. RAM frequency refers to the speed at which a RAM module can transfer data. It is measured in MHz (megahertz) and represents the number of clock cycles that the RAM can complete in one second. The higher the frequency, the faster the RAM can transfer data. For example, a DDR3 RAM module with a frequency of 1600MHz can complete 1.6 billion clock cycles in one second. This means it can transfer data at a rate of 12.8GB/s (gigabytes per second), calculated by multiplying the frequency (in MHz) by the number of bytes transferred per clock cycle (in this case, 8 bytes for DDR3 RAM).
