I can surely clarify your problems.
1) DDR3-1066 does not operate with XMP/EPP since it is below DDR3-1333. Core temps jumped because more voltage is being utilized at DDR3-1600 than DDR3-1066. At DDR3-1066, the memory is not using 1.50V. Even if you have it set at this, it is overvolted. So 3-4 degree jump from DDR3-1066 to 1600 is perfectly normal.
2) In CPU-z, are you looking in the SPD tab? Max bandwidth 667Mhz (PC3-10700)? That is the maximum default, DDR3-1333, like I was speaking about above. You will need to look in the memory tab. It should state DRAM Frequency ~800MHz 7-8-7-24. The memory tab shows the actual values the memory is currently operating at where as the SPD tab is the suggested values.
Thank you
