MRC

MRC => Memory Reference Code

找不太到說明的網頁,只有看到一小段

One of the most important aspects of the BIOS for an Intel board is the Memory Reference Code (MRC). 'The MRC is part of reference BIOS code, which relates to memory initialisation 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 and compiled by board makers. It provides a space to develop advanced features, and the ability to tune memory. '
