Hello everyone, good morning. *I am going to build one of these system. *In my city sells only KINGSTON ones. http://www.infobox.com.br/categoria.aspx?cat=46 I am not sure about wich memories I can use in these motherboards. Here are the options: 1) i7 2600k + mobo intel DZ68ZV ( I don't know what types of Kingston memories I should use on this mobo) I heard about issues using DDR 1600 . maybe I should use Kingston DDR1333 regular ones instead of hiperX ones??. I have read on intel web page telling to not use more than 1.65v, is highly recommended to use 1.5V memories. Theres diference of volts between hiperX and regular ones? http://www.intel.com/support/motherboards/desktop/dz68zv/sb/CS-032741.htm 2) MB LGA2011 Intel Extreme Series DX79TO - Box + ore i7-3930K (LGA2011 - 3,2GHz) I have the same questions about memories. In both Options I will use video card AMD HD 7950 or AMD 7970. PS: I do not like to use overclock Thank you in advance for all. Best Regards, Edde
