Hi
I have a problem related to that, the memory option that was there before when you pressed Memory> an option menu came i right side as mmatesic wrote.
There you could change mem settings between Automatic or manual setup, i kinda need that settings to underclock my ram to 1600 MHz.
I got G.SKILL Ripjaws 1866 MHZ F3-1866C10D-8GRSL after i saw a test on Legitreviews where it seemts to Work fine, but mine blue screen and make errors in memtest86+, but when i changed the ram settings to 133x12 (1600mhz) instead of 133x14 (1866mhz) it worked fine as far as i could see.
But the strange thing is a friend of mine got the same setup as my Nuc and same G.SKILL ram and it Works without any trouble at all, so i am wondering whats wrong with mine since it is possible to get it to Work with a setup like mine.
And when i am at it there is a proglem with USB 3 ports when using a verbatim 1 tb 2.5" external harddrive, if i do a coldboot with it plugged in it do not find the drive, even if i unplug it or use a different port, but if i reboot Windows after the coldboot it finds the drive, but you can also coldboot without the drive plugged and when Windows 7 is started plug the drive in and it findes the drive.
Hope you can help!!!
Best regards
