I'm going to be charitable and make a wild guess. There's probably some software section that checks a memory mapped region for a value from thermometers and throttles as necessary. It doesn't sound too difficult to make a mistake related to testing that region. If I were an evil overlord / dictator trying to follow one or more of the lists of things to do / not do... a dedicated hardware circuit for thermal overprotection would be among the must have items for any non-trivial device. Trivial devices being things that could fail with no risks, even from their worst failure mode. http://www.eviloverlord.com/lists/overlord.html http://www.eviloverlord.com/lists/overlord.html // https://tvtropes.org/pmwiki/pmwiki.php/Main/EvilOverlordList https://tvtropes.org/pmwiki/pmwiki.php/Main/EvilOverlordList

The way that is worded makes it sound like a certain German retailer is frequented by miners, and this is what the failure mode of RDNA2 cards look like when overclocked and overvolted until dead. The article says the users claimed they weren't mining, but, obviously, a miner wouldn't say they were mining with it, even though the strict EU consumer protection laws would probably protect them anyways.

  Miners almost never overclocked but tended to underclock and undervolt. Especially in a place like Germany where power is very expensive miners would be even more incentivized to find the optimum power/performance spot.

  Usually miners undervolt and also clock down the gpu. The memory is what gets clocked up. Majority of those deaths happen due to heat-up and cool-down cycle of the gpu between gaming sessions. Not implying that mining is light on the cards vs occasional gaming but if you game daily on it you'll have higher gpu temps during gaming. Source: had an rx6800 that mined for over a year and no such issue.
