I know that no one is interested in answering this question but is 520W at 1.1V considered safe for an RTX4090 that doesn't go over 65°C in temp?
should I see degradation over time with this settings?
 
That is fine. The original 4090s shipped with a 1.1V limit (though newer 4090s came out with a 1.06V limit, if I remember correctly).

FWIW, all silicon will degrade over time as it operates. It's normal and the user will rarely ever operate it long enough to actually see it happen (assuming normal operating parameters). The rate of that degradation is the difference (see recent 13/14th gen Intel issues).

Edit: 24/7 365 max load operation, such as mining or folding, would not be considered normal operation by most people and companies.

I don't know if the 1.1v is safe, my first 4090 died at 1.1V 600W 24/7 usage after 1.5 years. My 2nd 4090 I'm keeping at 1.05V 540W its nearly the same performance.

My SuprimX does not go higher than 520W at 1.1V because it's power limited at 520W.
What's your power limit? and what card are you using?
 
Since i´ve ran a 3080ti at 450 watt for 480 days straight at 100% my worries concerning burning up a gpu die or its ram are lessened.

Burning up a 4090s cable or connector is what still worries me.

So i´ve attached a temp sensor on the plug and did setup a HWinfo64 alarm.

what do you mean?

at 520W my cards performs 20% more than at stock.

You mean 2%? You won't he wattage limited with a 3ghz OC and ramping the vram a bit even with the default 450w. If you undervolt, you'd be under 400w with roughly the max the core can typically reach anyway then. Are you using some kind of exotic cooling like ln2 or chilled water?

no, I mean +20% of performance in most titles.
the point is that with demanding games there is no way to run the card at 3GHz core and 12GHz VRAM without feeding it with 520W.

I'm using a custom waterloop

You can do that on stock cooling, and yes it will be under 450w if you undervolt + power limit. This has been well explored at ocn and g3d forums :).

All that cards are simply not stable.
No need to explore this.

Very very few cards are able to do 3GHz with under volt.
Probably they can do it with light loads, but certainly not with the cards at full blast
 
All things entropy basic law of thermodynamics.
As systems (i.e. microchips) get more complex at a small scale there is higher probability of a failure.
Heat is a killer unless you operate at cryogenic low temps.
Shiny new things will replace your old things before warranty expires.
 
My MSI SuprimX 4090 I got a few months after launch. It's unlocked to 1.1V and 520W. It's stays cool, doubt it would hurt anything. However, even at 4k gaming, I only max out the power to 520W, but I cap voltage at 1.06V. Only when I benchmark or push for fun do I go with 1.1V. OCing definitely makes a difference at 4K, even on a 4090. I run mine OCed all the time with gaming and never have issues as I found the max stable OC for it.
 
There's definitely a silicon lottery with 4090s. There's some threads of binning cards on other forums and I've seen cards that run stock right at the power limit, and other cards that can run as low as 315W even at unlimited power limits at full load.

I find it hard to believe that there could be over a 40% variance in 4090 power consumption for the same workload and conditions.

Yeah, I've seen wildly different results. What I've never seen is someone claiming that an under 8% clock boost made their card 20% faster :ROFLMAO:.
