I have a 1080Ti which is hitting the Voltage Limit from an under-clocked 1468Mhz all the way upto 2050Mhz. Adding voltage doesn't remove the limit, the limit seems to be on all the time when the card is at load. Surely this isn't right?

Is the voltage limit set to 100%? If still limit than you cannot increase any further.

The 'voltage limit' isn't a *fault*. It is just an indication that the GPU was using the max stable voltage for that clock speed. GPU Boost 3.0, takes a bit of getting used to. The key thing is temps. The lower your temps the more consistent and higher your boost clocks will been. You've probably also noticed that even setting 120% power target and you still hit that fairly easily.

ya the voltage limit is always going to be your limit there unless your getting limited by POWER or TEMP or UTILAZATION before the voltage
Do you have water block?????? The only limit im seeing is POWER LIMIT 120% all day every day about every 5sec so sure wonder what your doing BRO.....voltage ha cant go over 1.000v before BOOM 120% power throttle coming my way

Hi Jacob, The Voltage was at stock in the first post, and the Voltage Limit is there even when I apply max added voltage +100mv and underclock the card by -400.  Undervolted by and Underclocked by -550:  What ever I do in terms of clock speed or voltage the Voltage Limit is set off which doesn't seem normal.

This card dosent seem to set off the Power Limit only the Voltage Limit. I have another 1080ti (watercooled) which does set off the Power limit on/off at very high clocks ie 2050Mhz. Although it never sets off the Voltage Limit. So the Voltage Limit doesn't mean the card needs more Voltage to be stable or stop throttling? Its more than its getting too much voltage? I have tried undervolting the card as low as it would let me with a power curve and still the Voltage Limit flagged. bryanernster

So are you saying that seeing the Voltage Limit triggered off when underclocked by -400 is totally normal? I cant seem to find a setting where a Voltage limit isn't set off be it stock, overvolted, undervolted, underclocked etc... unlike my other gpu which can run at stock with no limits being set off. As soon as this gpu gets any load bang off goes the the Voltage Limit.

Yeah I was having issues with my watercooled Ti downclocking while running at +165 core +225 memory with 120% power... I was going from 2050+mhz down to 1911mhz and dropping my 3Dmark by 1000 pts. I was told I was hitting the power limit. After multiple responses to my thread and a few hours of testing I ended up resolving the issue by slowing down the memory OC. A few people told me the memory OC doesn't make all that much difference anyway and errors will lower the throughput too. I spent a few hours testing and am now running at +175 core +100 memory with 120% power and after 30 or so benchmark runs the card has remained at 2050+mhz so I think I'm good to go. Latest benchmarks show 2063mhz and haven't dropped at all.

When you underclock by 400 you are not changing the cards tendency to reach max voltage and then limit itself. You are just subtracting 400MHz from the frequency when that happens (in other words, grossly overvolting for that given frequency). The card will go up to 1.03xV without adding to the voltage limit with MSI afterbruner. If you max the voltage slider on Afterburner the card will go up to 1.09xV the frequency slider has nothing to do with the voltage limit, but just adds or subtracts a fixed offset to the frequency at those settings. Do you have a screenshot of GPU-Z's data screen showing the voltage limit, and the frequency, GPU load, Etc. at that point? remember, memory OC and max fan will also help you reach your voltage limit sooner.

I see thanks for explaining a bit more on the voltage limit, so basically this card is overvolting all the time. However even when I undervolt it the Limit Warning sets off. In fact it is set off no matter what settings I run the card at which is what I am struggling to accept is normal considering my other/current card does not set off any Limit warnings at stock and only a power Limit when heavily overclocked, this card is on water so it negates the Temp Limit warning. I also have a friend whos card behaves the same and doesn't set off any Voltage/Power Limits at stock. Happy to post some screen grabs of GPU-Z of the card running at stock or underclocked/undervolted?

That definitely isn't right, but as long as you're running at advertised clocks I wouldn't be worried about it.

Its a replacement card on advanced RMA as the current card has coil whine, this means I have both cards here. Considering how much these cards cost I do not want to accept something which isn't right as it will just annoy me. nvidyuh

I am sure you will be fine.

Its an RMA replacement, I think its going back to EVGA even though they say its normal and just a silicone lottery. I'm not sure if they are hinting I have lost it with this card. Either way its not ideal.
