Question hitting the voltage limit when overclocking my GTX 1050 TI to the max

[pezku]

hello i am trying to overclock my 1050 ti to the max potential. My core clock is now +155MHz and memory clock is +925MHz, these are stable enough to run some benchmarks and temps are max 59c , but even though my core voltage is on +100% it hits the voltage limit while on high use. If i reduce the clock's a bit it doesn't hit the limit anymore. Should i just keep the clock's lower or is it possible to raise the voltage. + I don't think Superposition gpu performance test is enough to test stability, so recommend me a free software to test stability.

personally when testing a overclock you should see what gives you better gains more core clock or faster memory.

i would start over and see how far you can get the core clock before its unstable then go back to last stable clock speed.

then work on pushing the memory clock and see how far you can go before it stops being stable.

also voltage is locked its more a power limit at 100 percent

so i should push the memory with the stable core clock or with no core overclock? what software should i use to test the stability

Superposition should be fine i would push the core clock dont touch the memory till you can push the clock speed. once you have a core clock thats the max you can go without it crashing.

then make note of that core clock speed and set it to that number.
then start moving the memory clock in small numbers of 25 to 50 then 75 then 100 once you hit a unstable memory go back to previous clock e.g you hit 100 from 75 so you go back to 75 and try 80 to 85.

then that gives you your max core clock with your max memory clock save it as a profile.

Keep in mind that anything you set in these apps are actually suggestions to the card. The card's firmware has built-in protections that may prevent it from reaching whatever you said it should do if it thinks it can't do it safely.

In any case, hitting a voltage limit, assuming you're looking at "PerfCap Reason" in GPU-Z or a similar thing in other utilities, isn't bad. It just means the video card refuses to go further to the right in the V-F curve.

With regards to stability, what are you after? If it's just "video card doesn't crash" then sure, Superposition is fine. But if it's "FPS is within x% for y period of time" and you don't want to do the data gathering and processing yourself, 3DMark has a tool for that.

i did it. on superposition it works well with the max clock's, but when i open games or use userbenchmark the gpu power limit is hit and the application crashes. edit: i put on the power setting for dynamic clock adjustment and userbenchmark didn't crash. Peak power consumption was 95,6w and the TDP is 75w so it's at the max 125% at peak. Should i reduce the clock's to avoid reaching power limit. Does The voltage or clock speeds affect power consumption.

Yes, voltage and clock speed absolutely affect power consumption. That's the main reason manufacturers don't push hardware farther from the factory - higher clocks mean more power draw, lower efficiency, more heat to dissipate, and increased chip degradation over time. It's a bunch of tradeoffs for the additional speed.

The greatest roadblock is the built in Gpu Boost algorithm. It has too much free reign over the gpu, that it can override your settings as it sees fit, if it's not comfortable with the card's parameters.
Part of overclocking involves keeping the custom settings from moving so you can try to test and see if they're stable.
Gpu Boost gets in the way of that.
Run into the power limit too often? It drops down to the next highest curve it's comfortable with.
It's running a few degrees warmer one day? Yep, still does it.
Plus, there's no ultimate gpu benchmark; that's why things can look fine on one application, but turn into a disaster on another.

You won't find the absolute max, 'cause the card won't stay still.
