I read in another thread iirc someone explained that the voltage and clocks are tied to a curve, so when upping the voltage the clock appears to auto boost to follow the curve thus causing instability. In there example they specific
I haven’t tested it myself though.
I imagine if you specified a clock and then upped the voltage it would lock the clock and allow you to test as normal. But that’s just a theory.
If Shamino doesn’t update or maintain the ARC OC tool, maybe I will look at it since the FW tool is working.
Once, I upped the voltage and I suspect I tripped the watt limiter. Because it looked like Windows rebooted the system, but it just sat there with just PSU power and no POST, until I power-cycled.
That was when testing hours ago and it started with Cyberpunk 2077 failing with a freeze for multiple seconds, then the message from the Cyberpunk 2077 reporter about it being flat lined, LOL.
Shortly after that, it escalated with what looked like a literal video card shutdown! Now, I suspect a hard mod is required to go much higher now, due to a watt limiter. Unless that was because of IGS randomly cranking it up well past the acceptable limits.
Update: I was able to up the GPU core without those strange frequency spikes, if I disable the tuning, then re-enable it and only drag the slider to the number I selected, and don't move the slider again, before disabling tuning first.
Monitoring with HWiNFO64, I don't even hit 230W at 2.56 GHz! Looks like even Alchemist is efficient!
In short, it looks like the clocks go all over the place, if I move the slider and hit apply again, after I already selected a boost level. It looks like you must disable the tuning then re-enable tuning, before selecting another boost level.
