I know this isn't the same board, but I have the TP67B+ Rev 2.0 board, and whenever I get to a certain multi in overclocking (not sure exactly where it starts) whether I am using a fixed multi or via turbo clocking, when I start stress testing, my multi will drop. I am 99% sure that I turn off all the power saving features, but am not sure what could cause this. When I initially started clocking, I followed the video I will link to, but have tried other methods too. Thanks for the help.
It is hard to read in my system specs, currently running 2x4gb g.skill snipers 1866mhz 9-10-9-28 1t, but just got today 4x4gb of the 30nm samsung green memory that clocks amazingly. Have tried various ram settings to see if its ram related (XMP and not) which out any change. Also, on auto my board runs the ram at about 1.57v rather than 1.5v that it should, could that matter?
EDIT: Following the guide for 4.7ghz, the 2nd bit of code, you can see in that the person changed the Power Technology to custom, if I mimic this with my set up, I don't seem to get the multi drop issues.
