Following the link from the previous post, I was able to downgrade my bios the original 203 version with no issue. However the bus speed has remained the same. I also made sure to go into the bios and restore defaults and save, but still no change.
For now I am gonna give up and continue research into what may be causing the problem.

The bus speeds affects the overall cpu speed. Normally, on Ivy and Haswell (sandy bridge too I think), it is set to 100 MHz. You then take your multiplier, which with my i7 under full load with turbo boost, would normal be 32, to make the processor hit 3.2 GHz under full load. The problem with my laptop is the bus speed is fixed at about 97.5 MHz. So, not only will my CPU only hit about 3.152 MHz. My ram is also affected, it always runs at around 785 MHz instead of 800.
This problem can usually be fixed on Asus motherboards in desktops by going into the bios and manually setting the bus speed to 100 MHz. Of course laptops do not have this option changeable and it is usually always fixed in the bios.
For comparison, here is the same screenshot from my system. Just downloaded HWINFO64 to show you what I am talking about. The bus varies randomly, but you can see in the left pane that the bus is supposed to be set to 100 MHz in every instance, but the CPU status always shows a bit lower.
