Z87 Mpower Max

Question

Having issues not being able to adjust my CPU ratio for my 4770K through bios (currently running 1.2B8). Does not allow me to change my setting from 'auto' to 'manual'. Seems to be locked. Although, I can change the CPU multipliers through MSI Intel Extreme Tuning Utility and overclock from there with no problems getting 4.5ghz at 1.2 vcore.
Also, for those who have the Z87 Mpower Max, does the debug code not show temperatures like the Z77 mpower anymore? At the moment, mine only shows the debug code(s).

Answer 1

Is there a reason why I can overclock better and significantly have better temperatures with 1 stick of ram compared to 2 (dual channel mode)?
Just by going dual channel mode, my temperatures automatically go up by 20-30C under load and it gets even worse as I raise my vcore. Where as if I go single channel, I can throw a good amount of vcore and the temperatures will slowly progress. For example, if I use 1 stick of ram, I can easily attain 4.5 with 1.2 vcore with temperatures in the low 60's using prime. But if I go dual channel mode, temperatures rise by 20-30C, and goes to 80-90C, but it requires 1.25 vcore in order to be stable. Yes, I know the vcore is higher, but if I raised my vcore to 1.25 using single channel mode, the temperatures would be close as if I were still running 1.2vcore, somewhere in the low 60's. Like I said, raising my vcore in single channel does not raise my temperatures as dramatically as in dual channel mode. Another example, right now I am running at 4.8 with 1.37vcore with temperatures in the 70-80 C using prime. I wouldn't even be able to do this in dual channel because temperatures would hit 100C at 4.6 w/ 1.3vcore and eventually underclock.
I have tested both sticks in single channel and get the same overclock results. So, it has to do something with it being in dual channel.
My setup:
Intel I7 4770K
MSI Z87 Mpower Max
Corsair Dominator Platinums 2133 1.5v C9
EVGA GTX 780 SC
Corsair AX 850
Corsair H100i
