I have the same problem on my MVG i dont know if its a MB problem, but is very anoying has one cannot tweak the system correctly because of this, getting Multiplier stuck all the time is realy bad and only way to fix it is to clear cmos :(
Quote from the Asus forum.
strange issues with latest bios (1604)
suddenly , changing the cpu multiplier in bios stopped working . for example i changed it to 45 , during post it shows cpu freq @ 4500mhz , then once in windows , max freq is 3700 (under load) .
loaded bios defaults ,changed multi to 45 , same thing . once in windows cpu freq was up to 3700 .
uninstalled asus ai suite - no change .
then switched to second bios chip (original 0257) and walla , everything works fine .
switched back to the first chip , no good ...
finally , cmos reset solved it .
it worked for couple of tries , then got stuck again , now its stuck at 4400mhz , and changing the multiplier had no effect .
i reset the cmos once again , and so far its working .but i dont know when its going to go crazy again .
board is MVE
