    At first when i used Extreme Memory Profile (x.m.p.) ......[profile 1] my ocz ssd vertex failed to operate. after calc memory the ahci controller gave me that message : smart command failed.
    i think its because of the low ram voltage of the ram (1.25) . what do you think? The lowest setting for memory volts is 1.3 which i don't think i can use it because my ssd fails.

    1st) i want to ask if it's safe to run those g.skill (1.25v) at 1.4v
    2nd) any imrovements i can make?

    Yes, 1.40V is no problem

    Those settings are pretty good, so as long as the system is stable you are ready to go!
    Are you an overclocker? Have screen shots of your OC results? Please post and share your OC experience!
