Overclocking GPU Memory clock for Mining

[Ghost]

Does it harm for it? Does it reduce its lifespan significantly? Card is Aorus Master RTX 3070 currently set to following

Power limit : 55%
Core clock : -150
Memory clock : +1300
Fan speed : 85%

You should verify with a benchmark if you're actually getting better performance with overclocked memory, because after a certain point the memory can be still stable but performance will degrade, i'm not sure if it's only for GDDR6X (3070ti and higher) or for all RTX3000 cards, but still..try heaven benchmark, stock, +500, +1000, +1300 and see if the performance improves with each setting.
On my 3080 the performance is degrading at +1300 = gives stock like performance, at +1400 it's worse than stock.

That's obvious to be fair, using one variant of a product 24/7, and the other sporadically, will result in drastically different lifespans. The issue is whether or not mining actually (significantly or not) decreases the actual running-lifetime of the card, and I don't think there's been any evidence as to that here?

I've spoken with miners before, and ones that used Polaris GPUs (i.e. RX 570, 580) had to replace a lot of them because the hardware fails easily on cheaper cards. It's easy to tell that it can stress some cards to failure and shorten their lifespan, especially in larger farms because they're basically cooking in a room together for an extended period of time.

That's not proof of anything, just that some had issues with cards. Again, mining cards run 24/7, even a heavy gamer will be putting out what, maybe 60 hours a week on the upper-end? Something running 3x as long is bound to die soon, but again, that doesn't mean it actually LASTS any less time.

Actually it does, because you're not gaming constantly and it's not a constant load on the memory, but it is like that with mining, so my point exactly. It's difficult to measure it because you would be having to play heavy titles constantly, switching with people to keep the load going for the same amount of time, and even then you can't tell the difference just by looking at the card, a component either fails or it doesn't, and mining will bring more consistent failures, mostly with the VRAM because it's a primary point of stress with Etherium.

Learn to read faster. If you buy something I'd expect you to at least know something about it, or are you that much uninformed and following the crowd with regards to what you purchase?

Can you learn to get some critical thinking skills please? It will do you many favours.

Ok sir. Noted sir. You know everything sir! I sell my GPUs sir. I will sell my car sir. I will get rid of off grid solar system sir. Now all sorted right sir?

*sigh* people always think of the simplest conclusion because complicated multifaceted reasoning is too hard.

its like this entire debate about used mining GPUs. No one seems to mention the stress put on other components other than the gpu die and vram. I think the capacitors and chokes my be more at risk here and fan motors/ barrings.
But there appears to be no clear cut reason for or against. Having conflict that doesn't appear to be resolved that being said of course miners are going to try a justify the resalability of the used cards otherwise they have gpus which are worthless. Due to this miners will likely have significant bias which therefore this means the word of a miner can not be trusted.
