This can be just as easier, and probably more truthfully, read as "miners can no longer make the used market a minefield by selling overtaxed consumer cards without disclosing their provenance." Because, yeah, having ex-miner cards burn out is a pretty common thing on the used market. Great! Cryptocurrencies are not inherently good or valuable and cryptocurrency people aren't special and their world-burning habits and desires need not be privileged.

> Because, yeah, having ex-miner cards burn out is a pretty common thing on the used market. This is mostly a myth, miners cards are usually undervolted, and only a subset of the card is used. If your CPU only used it's floating point unit then it wouldn't be as intense as if you were using the whole thing. The only potential issue is thermal damage, but that's hard to place and has to be close to, or in excess of 90-110c.

  It's not a myth. These things get racked in stacks of GPUs in what may or may not be actually-cooled data centers. Undervolted or not, when you couple that with constant load you're stressing devices manufactured to consumer specs. The excusemaking is pernicious.

  ? My CPU actually underclocks itself if I am running a heavy AVX-512 workload. Actually, back when I had it in a cheaper motherboard, my system would crash because the MB couldn't deliver enough power to the CPU. But I agree with the first sentence. Lots of miner cards are undervolted because what matters is performance per watt, just like many server cpus.

    It underclocks, but generates more heat in the AVX-512 case (that’s the whole reason for the underclocking). If miners are undervolting to reduce power consumption, heat generation is going to lower by necessity.

  The core clock is undervolted while mining - but the memory clock is absolutely cranked to the maximum it will support. I've been idly mining on an RTX3080 for 6 months now, and the hashrate has slowly gone down about 20% since new. I suspect the thermal pads on the memory chips are slowly cooking. I replaced them once already and restored a bit of hashrate.

    out of curiosity, and if you don't mind sharing that info, how many bitcoins have you mined with 1 card in 6 months? Did it pay for the electricity and the card itself at the current BTC price?

      It earns about $6-10US/day, off surplus solar during the day and about 50c of grid electricity through the night.

        Interesting, that's much higher than I expected. Thanks for the info!

Having used GPUs in general burn out is somewhat common, but it's less common for ex-miner cards than for ex-gamer cards.
