Undervolting 1080ti

[Edgar R. Zakarian]

Hi guys,

I know what overvolting and clocking damages the electronics over time.

 

Is there some way that undervolting could cause any harm ? I've currently pulled all the sliders on MSI afterburner to the left. My thought is,cool and quiet gpu=longer lifetime ?? 

 

I only have a 1080p display with 120hz. So I didn't need all the performance power.

I'm not aware of any problems one would have with undervolting

You could decrease the power bar to decrease its performance on purpose, it will make the card cooler... but you can not actually touch the voltages without flashing the GPU BIOS since those are locked on Pascal.

One other question, if you didn't need all the power of a 1080Ti, why not just get a 1070 or 1080?

Your GPU will live longer than you will own it, so you will never notice any increase in lifespan.

I've just pulled ALL the sliders, POWER, Core clock, mem clock ALL the way to the left

Because I already got this. And bought it for the same price as 1070 A guy I know wanted to get Strix instead, so he sold me this one cheap.

Just in case you're interested. Bought it with receipt and everyting for 4200 DKK.

I've actually had multiple GPU's die on me, while I would still have use for them in terms of gaming.

8800 GTX (Bought new), GTX 560 (bought used), Radeon HD 6990 (bought used).

All 3 of them died on me. Now I'm on this one.

congratulations on buying a $800 graphics card and make it perform like a $200 graphics card.

Why would I need  like 200 fps in GTA V? If 60 or 120 is enough with the underpowering?

Not quite correct. Sure you cant just enter an offset value and make it work like AMD cards, but the voltage/frequency curve does indirectly allow that.

How long did they last?

Bragging rights.

What power supply are you using?

Uhm. 8800 GTX lasted until 2013 I think, 560 GTX lasted until 2014, Radeon HD 6990 lasted until 2016.

So nothing very special?

Uhm it's a cooler master V750.

This one

Anyway, back to topic, so nothing negative will happen by pulling down the power?
Prolonged life i guess makes sense, since less heat and stress on the components? (also lower temperature change from idle 30'C to load 49'C)

 

Just wondering if some components are designed to work at a specific frequency, and lower frequency might stress them more? (maybe that's not how it works? )

AFAIK, the card is only clocking as high as it needs to.

 

that means if the GPU would need to clock up to 1600 MHz to get 200fps, it should stay well below that on its own when it only needs to do 60fps because you turn on VSync - no need to fiddle with any sliders

Not, though undervolting can further reduce power draw. Think of voltage as force used to close a door. You close it with less force, the less wear it takes. Of course, if you close it too lightly you couldnt close it (in a graphics card the software crashes)

Well, apart from the GTX 560 all cards lasted reasonably long.

Great analogy. Thanks for that! :-D! I think I have my answer here.

Actually it's a bit different than that.

In CSGO for example, it will boost up to 1900Mhz or so, and the usage will only be around 15-25%.

Instead of keeping the clocks and power down and keeping usage to 100% at a cooler stage It's a bit weird.

So now it's limited to 11-1200 MHz. Very cool.

That's because of people using them for mining or not watching their temps.

Which is why you shouldn't buy used AMD GPUs.

Good tip, thanks.

To be fair the first 2 are NV. And 6990 came when the mining rush was starting  (first wave). High chances it wasn't even used for that.

None of the cards were used for mining. I know the guys I bought them all from.
