So those GPUs are run in the most effective way, that means undervolting and underclocking They run 24/7 so they keep same (low) temperature all the time

Undervolting and underclocking produce less heat it's true, but can damage the same than OC (btw it is the same for engine... and for alive organism too)... Also the H24D7 use is also the most bad thing for the less expensive version of the home use GPU card they have found on the market 😉 . Last point never trust the "still on blister, never use it at all" as anyone can have a blistering machine... BUT you can still do good bargain when the bubble crack, if miner said 1000, you offer 200, they always accept even if it still cost 600 lol *edit* don't forget to reflash the board with original bios as some use modbios for crypto too

You don't get out much do you

He's obviously not referring to individual miners who use their personal rigs for it.

I dont believe that one single bit, but if you can explain how that is supposed to happen, I will consider it with open mind.

See post 19.

Well they need to sell all those gpus. Be careful who you buy it from.

Price will go down for them , drastically , right now it is the tip of the iceberg , jus twait until it melts.

Ofcouse it is BS. UV can make HW go for longer , it is almost certain.

Look at it like this, get an incandescent bulb and a dimmer switch and leave it at 75% brightness and the bulb will still eventually blow through wear. The same would happen with a gpu, even undervolting it will wear the chip down over time so a gpu from a gamer that used it full tilt for a couple of hours a day is going to have less wear than a card of the same age that was undervolted and underclocked but was used 24/7, the mining card will infact have a lot more wear. Also lets face it pc gamers usually have quite well ventilated cases whereas miners have lots of these cards in close proximity to each other (think back to Sli and how hot they could get) so heat would have a big factor also.

I've bought over a dozen used GPUs in the last decade or so, never had an issue with any of them, they all worked perfectly for months or years, most of them I sold again and never had any complaints or return requests. The one card I bought direct from a manufacturer was a refurbished card from Gigabyte, it failed completely (PC refused to boot with it installed) within weeks and I had to RMA it. I got a refund and bought a used EVGA card. Never again will I buy new or refurbished. Plus the depreciation on a new GPU is huge, nothing depreciates like GPUs do apart from maybe luxury cars. Unless you're rich enough that it doesn't matter, you're basically ripping yourself off by avoiding used GPUs.

Any evidence for this? Smells like BS to me.

Not a sound analogy at all. Again, evidence please. The heating and cooling cycles of turning off and on every day cause as much wear as anything else, so an undervolted card with low temps left working 24/7 will likely have less wear than a card that's been warmed up and cooled down every day for years.

A gpu used normally go into a low power idle state, they are designed to power up and down so that wear on the gpu will be minimal, they are not designed to be run at full tilt 24/7 undervolted or underclocked or not, thats 168hrs or wear on the gpu compared to someone who games for say 20hrs a week, wear and tear occurs no matter the volt or clock, thinking it will magically disappear by downclock/volting is just silly and yes the bulb analogy is fine because it shows that the bulb degrades over time through constant use and not by undervolting and incandescent bulb will also last longer than the dimmed one if used for just a couple of hours a day.

If you think an incandescent bulb wears in the same way as a GPU you have beef with your school for failing to educate you. A GPU is just a microprocessor, or a few thousand of them squashed together really. Microprocessors can last a long time, I have calculators and amplifiers from the 80s that still work perfectly. If you want to waste your money buying brand new cards because you have an irrational fear of cards used for mining be my guest, but don't push your uneducated guess as scientific fact, go find an anti-vax or flat earth forum if that's your thing.
