Hi, :)
I want to overclock "Gainward Nvidia GeForce RTX 2080Ti Phoenix GS 11GB" with MSI Afterburner.
Does that work at all or do I have to use the OC tool from Gainward?

I don't want to install a lot of software forever. And I use Afterburner as always for the display.

Now I wonder if that makes sense?
Whether Afterburner is as good as Gainward's tool.
What is better?

Thank you and best regards, Sunface

The card will boost higher because of the better temperatures and because with water the temperature remains low and stable. The card normally stays at the high core frequency. Also you can put more voltage into the gpu and not overheat. Whether or not the cost is worth the small performance increase is a personal choice.

If you have two 2080 ti or 2080 cards then water cooling is likely required to stop both cards running at high temperatures and possibly overheating. The top card also does not get much room because the card below blocks the air intakes for the fans and heat tends to recirculate.

I had a crossfire system with two 290x cards. The top one died because it would run 10-20c hotter than the bottom card.

I don't use water cooling if that was your question?
No, I was asking what kind of temps your gpu was seeing in game?

The gpu has a thermal limit of 84C, so if by chance, you were normally already close to that, then trying to OC would certainly push it to that thermal limit.

Does overclocking only make sense with water cooling?
No. You can totally OC on air, but due to Nvidia's Gpu Boost algorithm, which is temperature sensitive - how high it will boost depends on power and thermal headroom available.
So, if the card were already running warm, you'd see next to no benefit from trying to OC.

The main issue with RTX cards is getting the RT/tensor cores stable. Control is the best stress test. Most overclock's fail in Control but are fine in every other game. You could be stable at +65-80 core for most games but will freeze in Control with anything higher than +40. The same with the RAM, Metro Exodus and Control are best to find a maximum vRAM overclock. Your overclock will be unstable in Control long before you hit thermal issues.

I also think I don't overclock. Your arguments are plausible.

Maybe I'll buy a water cooling system.
But at the moment the performance fits anyway.

Thank You
