Bclk should be 100 unless you manually tweak it and there isn't a lot of room for adjustment because raising it by even a little causes system instability. The bus is more than just the CPU so changing it means changing everything connected to it. Your CPU adjusts the *ratio* to reach different clock frequencies while the bclk remains the same. For clock speeds your CPU has a base frequency of 3.3ghz but individual cores can run lower if they are not needed. The advertised 3.6 turbo is single core which means you would ideally have a single threaded task running and not much else. As soon as you start multi-tasking and loading up other cores you won't be able to reach that 3.6 without tweaking/overclocking.
