The Memory Reference Code (MRC) is a fundamental component in the design of some computers, and is "one of the most important aspects of the BIOS" for an Intel-based motherboard.
[1]: 8 It is the part of an Intel motherboard's firmware that determines how the computer's memory (RAM) will be initialized, and adjusts memory timing algorithms correctly for the effects of any modifications set by the user or computer hardware.
With this in mind care needs to be taken when programming the appropriate values into the SPD [the part of a memory module that contains its operating requirements and specification].
If we put in more effort than our competitors, we can find more information.The MRC usually only provides support for industry-standard memory configurations.
For people who want higher memory frequency, we used the setting of 800MHz FSB:DDR2-800 in MRC, but overclocked it to work with a 1,066MHz FSB, so we could implement support for DDR2-1066.The article author describes the MRC as "One of the most important aspects of the BIOS for an Intel board" and the reason why "one [board might be] a brilliant overclocker and another [is] as stable as a plate of jelly on a bouncy castle"; adding that "When you're overclocking, you're literally running clocks faster than normal.
