ASIC and overclocking, amirite?

[applesuxD]

Basically i am overclocking my r9 390 properly after watching jayztwocents video on asic quality, i notice that when i put higher voltages same clockspeed, the unigine heaven totally goes crazy, but when i lower the voltage, the thing was super smooth

 

ASIC quality is currently 78.1%

 

Is this supposed to happen?

Jayztwocents mentioned that sometimes, lower voltages can help overclocking, then goes on elaborating like how "too much voltages" is gonna affect very badly.

I posted this to know if this situation is what he meant?

 

Maybe for some of you guys this is common sense, but i think this will be a very helpful thread,espescially for people who are learning to OC nicely...

 

tnx babes <3

GPUs have a power limit, if you're already hitting that limit, increasing the voltage will only make the card power throttle even more, resulting in less performance and possibly dips.

So lower asic quality -> should max out voltage addition at a lower threshold?

Not really, asic quality doesn't really predict anything, it has to with binning at stock clocks, not how it will overclock. There's only a correlation with good overclocks.
