s about voltage and frequency for the GTX 1080ti undervolt/underclock settings
Hi,
I noticed both of my WS CPU's are a bit slow at 1080ti Gaming OC. I thought about undervolting and underclocking the GPU since pushing too much power isn't practical. I ended up getting around 1900mhz at 0.893V, which seems fine. Now I'm trying to lower the clock speed further (under 1900mhz), but each attempt seems to push the voltage higher—like 1200mV in that case... Is that acceptable?
The spike at the end of the voltage curve is typical. I saw the same on my 1080ti as well. But my card never hit that level. It will remain at the minimum voltage required for the frequency it's designed for, which is within its "working range." The 1.2v is significantly higher than what any non-modified 1080ti can reach, so everything should be okay.
I really wouldn’t bother because the GPU will be using only a fraction of its capacity at that speed. You might be running at 60% at 2000Mhz or full power at 1600Mhz. The impact on power use would remain the same. But if anything on the screen requires more processing, the first case could reach 65% at 2000Mhz, while the second would cause stuttering since it has nowhere to go.
Modern cards and CPUs are quite careful with power consumption; they only draw what’s necessary, using a very precise method. It’s likely they’ll run slower and at lower voltage anyway, which should make them perform better than yours.

You won't be able to select two options as the correct answer.
