MSI afterburner - is it safe to increase core voltage slider to max

[sunshinewelly]

got a new 2080 and note that with nvidea OC through afterburner the suggestion is to slide the top 3 boxes to the right ie core voltage, power and temps.

on my last card a 1080 i would only touch the power slider.

is it safe to simply set the core voltage to 100% and if what does that slider actually do

You can just set it to 100%. The maximum voltage on Turing is 1.068v and you can't go over that no matter what you do with the slider. Maxing it should provide additional headroom for overclocking.

The "100%" part is a little misleading. It's just saying "allow the maximum extra voltage permitted for this card" which is still only a small bump over stock max voltages.

You're safe to slide it right up - it can help with stability but can also increase available clock speeds. It can also add heat (obviously) and lead to higher power draw meaning power limits may be reached. There's a balance involved.

I found my maximum benchmark scores were without using all the available extra voltage - I assume this is because I avoided hitting power limits. You may or may not have the same experience. Experiment - it's safe to do so

I set them all to maximum even the fans, Keep memory and core default this keeps clocks normal but the boost will be higher and temps too.

Then you could start to try +25mhz steps on the core until the max is found. Wait some time then repeat on the memory. If all is well this is the way i do it i make sure i get all the power draw for the cores before memory.

the slider actually does very little, which is no surprise, I consider it a hype feature.

If you watch the voltage curve and max it out, you will notice maybe 2 or 3 intermediate bins get a one notch boost, thats it, the entire effect.
