So.. Intel says that for ivybridge memory can be 1.5V +-5% that is 1.575 V
I think that 1.65V is 10% more. maybe B-75 is not good for that voltage but good Z-77 MoBo is going to bee fine with 1.65V memory. If cpu is cooler properly.
Eny good cpu or MoBo is not going to break down with 10% over volt usage.
