MSI afterburner voltage limit and 3080

[Cavallino]

Folks there is voltage limit which is a viewable element on the osd.

It always seems to be at '1' when I'm playing games.

Does this mean there could be something wrong with my card or is this quite normal?

Thanks.

It’s normal, it’s similar to the GPU-z limit readout, it’s just highlighting what is preventing your from boosting any further. In MSI AB, 0 = No and 1 = Yes, so all it’s saying is your not boosting further as your at the voltage limit. Entirely normal to have a limit of some kind preventing further boosting, weather it’s temp, power, voltage etc.

I imagine your clock speeds are showing above the box speeds.

Well that's the thing. If I don't over clock my GPU and run normally. The limit does flag up.

So I'm not sure how I interpret this.

nothing to do with over clocking. These cards automatically boost out of the box. Take a look at your clock speeds, in most use cases your clock speed will certainly be sitting above the clock speeds that is slapped on the side of the box that the card is rated for. The cards all have a boost table in the background and they will keep trying to boost as high as they can until they hit a limit somewhere.

I see so you mean that regardless of overclocking or not, everyone is going to hit a voltage limit due to the "boost function"?

As above, can be limits somewhere which is not just voltage, can be temp (though less of an issue on these GPUs), power, voltage or even FPS cap (from limit you put in place or the CPU not able to deliver the frames). However voltage when under a heavy load is pretty typical to see. The card has a boost / voltage table in background, you can actually see it in MSI AB if you clock the curve button. It will try to hit certain frequencies by selecting a corresponding voltage. It will however only go up to a certain voltage and no go any further hence you will see voltage limit showing up.

So yes, there is usually a performance limit somewhere in most cases and voltage is a pretty common one to see if your not running into thermal or power first.

Voltage limit, yes, Power-limit, yes.

Your best bet is to under-volt.

Even if you shunt-mod the card with solder or liquid metal, the 3080 cards remain power-limited.

Personally, i don't think that's an issue because you have to draw the line somewhere.

Ok sweet, thanks.
Is there anyway to ascertain if I am getting LESS than what I should be as a base clock on the box?
I guess if I underclock to the frequency on the box in theory it shouldnt be hitting a voltage limit?
