KT7A's 7.5 multiplier won't work

Hi everyone,

I also post this in the OC forum but...

I have a KT7A-Raid that I have been ocing on and recently found that the half step multipliers (6.5, 7.5, 8.5) don't work with my bios settings tweaked. (I followed AthlonOC's KT7 Tweak guide to optimize the settings on my mobo http://www.athlonoc.com/KT7tweakGuide1.htm)
Does anyone know what setting might be causing me to lose the half-step functionality?

Thanks
