We first looked at

Find the "CPU/NB Voltage" setting and bump it 0.01 or 0.02v and test stability.

yes I see the entry in the Manual. I did not have this I had the "Quick Install guide."  Thank you for pointing the Manual out to me.

 I have never modified settings like these before so it seems daunting. Meaning I do not have command of the OC realm.  Hand holding may be needed.
 I see that if I select CPU OC instead of manual that I can change the NB voltage as in CPU/NB so should I be in "manual mode" or "CPU OC mode"
 As such in CPU/ OC I do not have choice to add 0.01 or 0.02 it allows selection of 1.5 xand 1.6x or more or less

  I figure I should ask before I do. You seem to be one who knows a bit about OC

I'm not feeling like I am closer to a solution. I'm not sure what I am to try.  I have been able to select higher CPU OC 10% for example if the RAM Speed is 1600 or lower.  Naturally reported memory speed is higher with CPU OC such as 1788 mhz @ 10%  Nothing I try allows for 1866. So we were wanting to increase NB voltage?
