First, the basics. While memory frequency is measured in Hertz, or cycles per second, the unit for memory timings is just plain cycles. To convert clock cycles to a measurement of time requires knowing the frequency of the memory. This is listed in MHz, or units of 1,000,000Hz. 3200MHz memory has a clock … See more That last paragraph requires some additional explanation. Every stick of RAM contains information baked into EEPROM (Electrically Erasable Programmable Read Only Memory), including some safe timing/frequency … See more So, when it comes down to it, RAM doesn’t set its own frequency and timings--the BIOS does, with SPD/XMP as a starting point. On Intel boards, this element of the BIOS is called the MRC. This is one area … See more With all that out of the way, it’s time to talk about the primary set of timings.
