Trixx -OC stable, AB 4.2.0 - OC unstable (crashes within 3-5 minutes)

Hi there.

I'm having a strange issue with afterburner.

I'm running my fury at 1140/570, power limit+50,+72mV, custom fan curve.(temperature never exceeds 52-53+C under load)

Trixx: everything is stable, furmark, benchmarks,hours tested-no issues. different games and what is most important witcher 3 (one of the most sensitive to unstable overclock games I've ever seen)

AB 4.2.0(same OC):

Witcher 3 crashes within 3-5 minutes every time.

I have amd catalyst driver 15 .11.1 installed but I've tried the latest crimson driver and Ab has the same issue. Unfortunately I couldn't check Trixx coz crimson driver resets core clock to 1000 all the time,I didn't even touch overdrive obviously, I can OC only memory).


I tried uninstalling trixx, uninstalling AMD drivers using DDU in safe mode and installing them again, uninstalling AB and installing it again and whatnot.

I only have "unlock voltage control" enabled and "extend official overclocking limits"(so that I can OC HBM)

How do I check what is exactly wrong here?

Thank you.

PS Fury unlocked to 3840. Stable(no aftifacts, no throttling, no nothing) in everything at default clocks and , as I've mentioned, at my current OC with Trixx.

 

Here's another sample.
My Fury X was very stable with Trixx at 1160/500, +50%, +48mv
But with Afterburner, I can't stabilize my fury at 1160/500 +48mv, even with more than +72mv.
Now I'm using 1120/500 +60mv. I dont' think it's best result but I'm tired of crashing.
I'm just wating for another afterburner update.

 

I think I know what causes it

Check voltages(right column, I used Trixx and AB logs)

Trixx stock voltage

Ab stock voltage

Now, pay attention

Trixx OC +72mV

Ab +72 mV

It looks like Trixx actually pushes more than +72 mV for whatever reasons, whereas Ab is more accurate in this regard.

PPS OK.. I've increased +mV in AB to +96mV(it should be enough if we take a look at stable trixx OC voltage) and I still got crash within 2-3 minutes.

Judging by AB logs

this time AB was pushing less voltage most of the time than was specified

I guess I'll have to stick to Trixx..
