I rolled it back to the previous, non-beta BIOS and set all the Turbo Boost multis to 45. Seems to have stuck, the CPU stays at 4.5GHz when I run Prime95. I guess it was a bug in that beta BIOS that they never bothered fixing, just my luck as my keyboard doesn't work in the BIOS now and I'll have to dig out an old PS/2 one whenever I need to change a setting.

If IntelliStep (or any other power saving tech) is enabled, you need to put some load on CPU for it to show proper clocks in apps like CPU-Z. Otherwise it'll run downclocked and of course have lower clocks.
