without changing the voltage or maybe slightly increasing it
Shouldn't make a difference. 1050 Ti has locked voltage. You could use 100% without damaging it because it won't go above a certain number.
Do you recommend overclocking it?
Sure, why not? Unlike CPUs, it's far easier and safer.
Just thought if I could get more performance out of 1050 Ti without sacrificing much.
5-10% boost. 15% if you're lucky.
--------------------
If you need a guide:
0. Install MSI Afterburner
0. Download and run UNIGINE Valley on
Ultra.
1. Max your power limit. (You PSU should have more than enough power)
2. Increase your core clock 25+ at a time while looking at UNIGINE benchmark till artifacts (weird lines and colors) appear or your driver crashes. Then fine tune it compared to your previous clock.
Example Core clock: +25 > ... > +150 > artifact > +125 > ... (Keep it 25 or more below max)
3. Do the same for Memory. (50 or more below max)
4. Save your profile.
5.
Don't check apply overclocking at startup. You can check it after few days of testing.
Keep your temps
below 80c/176F, if you go over it or stay near it., consider installing a fan on your case near the GPU. But I doubt a 1050 Ti could get that hot.
