The MRC is part of reference BIOS code, which relates to memory initialization in the BIOS. It includes information about memory settings, frequency, timing, driving and detailed operations of the memory controller. The MRC is written in a C-language code, which can be edited andcompiled In computing, a compiler is a computer program that translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primarily used for programs that ...by board makers. It provides a space to develop advanced features, and the ability to tune memory. We try to look into ntel'sMemory Reference Code to try to understand its behaviour ... Sometimes, there are some remarks inside the source code, while on other occasions, we just try to change the arguments to see what effect it has. If we take the time to understand the MRC then we can get more out of it. 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 instance, under a 1,066MHz FSB, the only choices regarding memory speed in the MRC are DDR2-667 and DDR2-800. We have to provide additional choices. 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 oard might bea brilliant overclocker and another sas stable as a plate of jelly on a bouncy castle"; adding that "When you're overclocking, you're literally running clocks faster than normal. Working out the effect of this on the various different components on the board is a task that a good BIOS must be able to handle."
