In order to obtain proper performance our recommendation is testing with components within the specifications given before. Please check the following links:
Sorry i didn't understand you,
you want to tell me that i can only use DDR1066/1333Mhz memory with 1,5V ?
I never used memory with higher voltage - and low voltage memory IS supported by the DZ68BC.
Thanks for your help.
