Crimson causing black screen on CPU ratio change?

Hi all,

 

I've an AMD/MSI setup which, since upgrading to Crimson, has lost a little bit of the functionality I'd been enjoying. As some of you probably know, MSI Command Center is a piece of software bundled with MSI boards that lets you (amongst other things) alter the CPU ratio from within Windows. Using this, I was able to run with my CPU locked @ 21x for gaming etc., and lower it to as little as 4x when workloads were low or I wanted to keep the fans at their lowest setting.


This all worked fine under the Catalyst drivers, but since upgrading to Crimson any change in the CPU ratio results in a black screen. Now, Command Center was updated around the same time, but I've rolled that back to no avail.

 

What could be causing a conflict like this? It seems odd to me that changing the CPU ratio should affect the display driver at all.
Could AMD chipset drivers be involved somehow?
Has anybody else run into this problem?

Are there any alternative programs for adjusting the ratio on-the-fly that I could try using instead of Command Center?

 

Thanks
