4.5ghz works fine, but one multiplier up and windows insists on using 15.5 .
I had a similar problem years ago with a e5200, I thought I had got a 5ghz bench run but it had been running with a lower multiplier then it should off.
Were you able to sort out the e5200?... Might be along similar lines.
How about C1E support? C1E can auto magically reduce the multiplier as well as a few other things for power saving.
