I have the Intel D845EBG2 Socket 478 motherboard. This mobo supports 533 MHz. I am currently running the 2.26 GHz CPU. I would like to upgrade this computer one last time to get as much out of it as I can. The Intel website says that the 2.8 GHz CPU is the fastest that the mobo will support. However the website also says that the mobo is no longer supported so not sure if the info on CPU size is accurate. My question is this; Why wouldn't this mobo run the 3.06 GHz that also runs at 533 MHz? Am I missing something?
