Is 0.9 voltage enough for ZOTAC 1070 ti? Working on 1911 frequency.

[KalashnjukUA]

Hi dwellers!
So, what do you think of the voltage? Is it an acceptable one? Playing such games like The Witcher 3, GTA 5 and running the benchmarks like Furmark, Heaven, Superposition, OCCT everything goes fine, as far as I can consider it.
So, shall I leave the voltage?
Thanks to you all in advance!

Have you changed the voltage, or is that just how it is?

If thats just how it is from the factory then its fine, and probably means you have got a good chip.

I've changed it by myself.
Factory voltage is around 1.06

That's a very good undervolt, if it's stable. My card is running on 0,9v for ~1.5 years now without any issues. The only effects will be less waste heat and quieter operation.

Why did you lower it?

If its working fine then you can leave it, but you may get lower performance or instability.

What frequency is your card working on?

 

[RobCrezz]

Mines slightly overclocked so hits around 2100mhz in games.

You know, I did it since I wanted to lower temperatures in games.
The only thing I want to know is whether the voltage is judicious?

Still waiting for your comments.

I tuned the voltage curve to max out on 0.9v @1860mhz. Default would be 1987@1.05v.

The card was running in the mid to high 70's C and quite a bit louder at stock values. I did oc memory by 400mhz to lessen the performance loss.

Very happy with this result. Less noise, heat, consumption while being more quiet and performing the same.

So, basically 0.9 is enough for 1911 Mhz?

It differs from chip to chip. Golden silicon might do 1950mhz@0.9v, while a bad chip might not be able to get 1750mhz at the same voltage.
It's something you have to test out for yourself.

How to make certain everything goes stable and non problematic?

When your games don't crash while overclocked i would consider it ok. If you get artifacting or driver/game crashes you need to lower the clock or raise the voltage.

Try running something like Unigine Superposition:

Very good test for stability.

I've noticed some a pinprick...
You see, I've set 0.9 voltage, but in a game it may very up to 0.92, not more, though.Why does it happen like that? Whatever voltage I set, then it rises up a bit. The temperatures are fine while running. What's the matter, guys?

Pretty normal, there will be minor fluctuations when the card is under heavy load.

So, there is nothing to worry about? Does your voltage flactuate either? I thought it would be completely stable and not variable at all, since the curve in MSI Afterburner is settled on 0.9 only.

Yep, mine fluctuates between 1.03-1.06 depend on the load and whats on the screen. When not gaming it drops down to 0.6250

Your voltage is a stock one, though, but mine has been set by me and it varies a bit so far.

Yes, thats normal.
