@MaxLG:
Does anyone know what they are for? 
What motherboard do you have?
If it allows OC through the bios, it's better to forget about that SetFSB, that was useful for benchmarking or motherboards that don't allow OC through the bios. Also, you need to have the version and microcode of your motherboard to be able to change anything.
I haven't touched it in a long time because I have motherboards that allow OC through the bios and I always configure it in the bios or UEFI, but those bars will only be one for increasing frequency and another for Pcie, I can't remember exactly, the one above is for increasing fsb, I think.
