Guys I have a weird issue with my P8P67 EVO - everything works fine but with my last two o/s installs (for benching) AI suite shows BCLK at 4.2mhz and wont accept any adjustment, whats going with this and how do I fix it? If I put my gaming HDD back in (with old o/s install) it works fine so it doesnt seem like a hardware issue....

Any help would be great.
