so ive been ming for a couple days. i have my power limit set to 80% but i noticed on the graphs(https://imgur.com/a/f5DVVfw) that there are some spikes over the limit, up to 100-120% at the peaks of the circled spikes. is this a reading error or something that absolutely shouldnt be occurring?

Another question I have: I have read that running GPUs at 100% power ruins the longevity of the cards. Does overclocking the core and memory clocks have the same effect?

Last question: I've seen conflicting information. Does running at 100% power ruin cards or does running at high temps (i.e. 70+) ruin cards. ive been running at 60% power and have been only hitting 39-51C. is it safe to up the power? the thing im struggling with is finding overclock settings. what ive been doing is upping the core by 25 and the mem by 150 and seeing if its stable. but i feel like ive already overclocked it further than i should. how do i know when its too much? right now im sitting at 60% power, +150 core, +700 mem mining mtp (zcoin)

I think that's just myths. As long as your cooling is OK (fans can sometimes die on GPUs, never had the issue, but it can happen) your cards will not have any longevity issues. Most of my gear is comprised of RX470s that are past 2 years old now, they still run like a charm.

The same goes for when I was selling some of my gear, people would always ask "Has it been used for mining???".

They assumed that because you use a GPU for what it is essentially intended for (do calculations. I mean when you game, it's the same thing....) the GPU would be worn out and on its way out. Which is about the most retarded question you can ask.

The fact is most miners will actually turn things down a notch with voltages and usually tune the card's frequency in by often underclocking it in regards to the undervolt. What matters isn't having the highest hashrate, it's having a stable GPU that doesn't give you high numbers of stale or bad shares and that you can leave running for days on end without a problem.

So the conclusion is that if there was any scientific evidence on if overclocking had any effect on a GPUs longevity, you could make the point that a miner's card would be in better shape than that of a gamer who would usually try to overclock the card to get the max performance out of it.

Regarding temps, GPUs can handle 70°C and up no problem.

Also look on the pool side of things. How does your reported hashrate match your miner's hashrate. Any large discrepancy means you likely went too far with your over/under clock/volt.
