I KNOW WHAT MEMORY AND WHAT MAXIMUM MEMORY SPEED SUPPORT MY MAIN BOARD BUT I DO NOT KNOW WHAT MAXIMUM MEMORY SPEED SUPPORT MY i7 870 CPU because there are "Memory type : DDR3 1066/1333" in spetification of this CPU. THANKS IN ADVANCE.
the i7 series supports 1066 and 1333MHz RAM officially, however, you can put in 1600MHz RAM into it as well. I'm not sure if it supports anything higher. it also does not support ECC memory
