You should e-mail MSI tech support about this issue, and you may want to start a thread on the MSI forums as well. The issues with EIST may also be a factor of missing / incomplete BIOS support.

In the mean time, I would suggest leaving everything at "Optimized Defaults." When MSI releases an update that addresses the half multiplier issue, you should then revisit your OC efforts.
Good idea, will do. In the process of putting the 8400 in now and if that gets me back to EIST disbaled with the 7.5 I'll leave on defaults for now.
