mega-bump, but I just registered here just to comment on this cause im having the EXACT same issue
wich im currently discussing here: http://www.overclock.net/t/1324236/over ... ome-issues
difference is: OC isnt automatic, I did it manually per core (although on this board you cant set the Vcore setting, so that's the only thing auto, but it works fine (1.3V)
here's a picture I took, good example of what the OP is talking about:
Ive been trying EVERYTHING and havent found a solution. So if someone out there has one id be inmensily grateful.
my guess: the mobo is just bad for overclocking and it hits some sort of limit (defined by either heat or voltage or something) and automatically throttles down. Ive turned on and off every single power saving feature (and every single feature in general for that matter) and still cant fix it.
my way of dealing with it: I just use the OC anyway (currently at 4.5ghz). Im yet to see a game that will stress a CPU as much as a prime95 blend test, so it shouldn't
be an issue, but it would sure be nice to fix it.
Fuck the "LE" at the end of this board
should have gone with p8p67 PRO
