I installed 2 sticks of g.skill ares 16gb(2x8) 1866mhz/10-11-10-30/1.5v in the first dual channel (slot 1 & 3) and an 8gb (1x8) 1866mhz/10-11-10-30/1.5v in the second channel (slot 2). When I run cpu-z/speccy etc. It reads @ 666mhz (1333mhz dual) and the clock at 9-9-9-24. Im running a 970 Extreme4 Mobo that is capable of supporting up to 2100 Mhz (oc) or 1866Mhz. So, when I went into bios and manually changed each ram stick to 10-11-10-30, and the clock speed to the rated 1866mhz I was getting some really effed up readings. The ram frequency became unstable in speccy and it was going for 666 then crashing to 0 then spiking up high, and I had some weird things happen like after I saved the bios and exited then it wouldnt display anything even tho I could hear the pc running, I had to hard kill the pc and restart then it would load windows and even then when I checked the MHZ it was still hovering around 667Mhz in cpuz which would be 1333mhz dual. I finally got all the settings back to auto in the bios and everything is running fine again but can anyone tell me is there something Im not doing probperly? I really want to get the maximum mhz out of my ram because I am running a Ram Drive and atm the ram drive is not much better than my actual HDD.
