OK Boris, I have read your CubeMod at http://www.cubeowner.com/overclock.html so I know you know what you're talking about. The screen doesn't go grey but it rather the processor slows down to a crawl. Or at least it seems like the processor, but maybe it's device access. I'm going to experiment for a few hot days and collect information.
