Mining cards are run near always, while gaming cards are usually pushed only a small number of hours per day.
I have no data to back this up but anecdotally this makes a huge difference in wear.
- pantalaimon 6y agoGPUs are not mechanical parts (well save for the fans but those can be replaced). I would imagine thermal stress from heating and cooling would be the biggest issue - you don't get that under constant load.
- iforgotpassword 6y agoHeat = bad for silicon. Also electromigration. And probably a couple other effects I don't know about.
- R0b0t1 6y agoHeat is bad, but MTTF at usually achievable temperatures is hundreds or thousands of years. Electromigration matters on the order of 100 years.
- namibj 6y agoWell, tell that to my chipset's SATA controllers (Sandbridge generation). Intel messed up their life expectancy calculations, and thus they died after 2~3 years. I think 2 are still alive.
- o-__-o 6y agoLooks like you should have put a fan on that chipset. Like your GPU, which runs at extreme temperatures for extended periods of time!
- namibj 6y agoIt was cooled by the OEM config. And the chipset did get nice airflow.
- pantalaimon 6y agoThe Sandy Bridge SATA issue did make big waves back then and Intel did a recall IIRC. Only the B2 stepping of chipsets should be affected by this tough. https://www.anandtech.com/show/4142/intel-discovers-bug-in-6series-chipset-begins-recall https://www.anandtech.com/show/4142/intel-discovers-bug-in-6... https://techreport.com/news/20326/intel-finds-flaw-in-sandy-bridge-chipsets-halts-shipments/ https://techreport.com/news/20326/intel-finds-flaw-in-sandy-...
- namibj 6y agoI guess I should have gotten a replacement board. I'll probably just upgrade to Zen3 soon, so it'd not be worth the effort (the machine in question is off and in storage).
- locuscoeruleus 6y agoHuge difference in wear, yes. But not in the direction you think, I think. Warming up an cooling down is more damaging for a card than running constant temperature. It 'jiggles' parts more.
- AnHonestComment 6y agoThat seems true of structural components but untrue of silicon, where the heat output difference is literally the GPU being jiggled more aggressively inside by the miner. Heat dissipation is due to jiggling the tiny gates a little every time you fire one: which cycle much more often in the mining case — at a higher temperature, where there’s more likely to be damage.
