I'm running 24/7 @ 4ghz (182x22) but I was thinking today, how can the 930 use a 22x multi? 21 x 133 = 2.8ghz (stock speed), so how is it that I'm able to use a 22x multi when overclocking and with turbo mode disabled? My bios lets me select 22x just like 21x...

Also, my bios and cpu-z say 4ghz but right-clicking on "my computer" says 3.83 ghz. Since 3.83ghz = 182*21, is it just thinking I'm using a 21x multi?

Running benches such as cinebench and super pi definitely indicate 4ghz clocks and I tend to believe my bios and cpu-z over windows reporting...
