My memory frequency on the Memory tab of CPU-Z reports 100 MHZ, is this correct? When I overclock the FSB to 250 it will then read 125. Forgive my ignorance if this is a dumb question.
Yeah, that's just how ASUS records memory dividers in their newer BIOS's. The last several ASUS boards I've worked with all had memory listed that way. For example the A8N32-SLI, A8R-MVP are all that way.
