Are you still using offset? I was using it up until I read about the failed boost issue and personally I had no problems with failed boosts after stress testing on y-cruncher and setting my voltage appropriately. That said I'm using manual at 1.4V now just in case there is some failure in the future.
This discussion we had several pages back maybe the "magic bullet" to solve overvolting when on PState OC and AMD CBS reset but Extreme Tweaker does not
So CPB off.
. So if AMD CBS reset it would be 1.000V + offset which I use is +162mV = ~1.162V
With CPB on CPU is using PB/XFR, so will go to 1.35V and if borked boot happen, with offset, = ~1.5V .
With CPB off, CPU in OS for single thread only boost to 3000MHz. This fits perfectly with what I had been saying before that in the case of R7 1700 when we change PState 0 from [Auto] to [Custom] the 1185mV is ceiling of VID/VOLTAGE.
We have also seen VID is ceiling when lowering PState 2 to reduce idle voltage which has increased due to offset used for PState 0 OC to stabilise.
Am now gonna start switching off rig on 3.8GHz PState OC, but gonna have CPB off
. Come thee borked boots I am ready!
