GA-P55A-UD4 upgrading memory but with...too high QPI Frequency?

[Ri-Sa]

Hello:

Until a few days I had two memory DDR3 pc3-10666 (1333Mhz) running in my motherboard...Everything stayed normal (QPI Frenquency was 4797 Mhz [36x] and the UnCore Frequency 2132 Mhz [16x])
I bought an 8GB kit from Crucial Ballistix 2 x4GB 1866 Mhz CL9 1.5V...but when i try to get the BCLK Frequency at 187 Mhz and Profile 1 at XMP then the QPI Clock Ratio in Auto the QPI Link speed goes up to 6.73 Ghz or if a set it to x32 it goes up to 5.98GHz...are not these too high...
I have installed Aida64 and everything seems normal but when i go to Sensor the PCH temp says PCH 70 °C (158 °F)...that maybe is too high (if I reset the computer the value of PCH temp shown in the bios is around 50 degrees celsius...is Aida64 wrong??)
I have two 12cms fans at 500rpm one blowing in fresh air and the other one taking out the hot air.

Is just a matter of moving more air? did i do a right setting for the memory? is the PCH temp normal?
I need some help

Thanks
