i should have clarified, i can't run any of the 4 enhanced modes on my mobo without errors in game. regular stock is fine.
I've seen you post that before about PBO not working but didn't make much of it as it was a tangent. However all the boards I've seen have PBO on auto stock. Technically PBO on auto is disabled.
"Precision Boost OVERDRIVE is what AMD is calling it when those three thresholds are bumped up.
The default setting for PBO is “auto,” which the stock specification defines as disabled; further, AMD’s own review guide states to disable PBO for reviews, as the Overdrive portion is not spec. That’s what we did for our review, just like how we disable MCE for Intel. The default numbers can be pulled from the chip (overdrive disabled) or higher numbers can be pulled from the motherboard (overdrive enabled). Setting overdrive to “enabled,” setting overdrive to “advanced,” and specifying the motherboard as the source did the same thing on the two boards we tested for this content, but the two motherboards set different values."
Thus if you have to disable PBO outright then you've got issues. It's only between your cpu and motherboard... Any of the four modes causes crashing then I'd look at your board.
