The Ethereum blockchain changeover from Proof of Work to Proof of Stake, generally known as the Merge, successfully meant crypto coin mining with shopper graphics playing cards was not worthwhile. Whereas players seemed ahead to cheaper new and used GPUs turning into the norm, in line with a sequence of movies posted to Twitter by I_Leak_VN, GPU crypto miners in Vietnam seem like jet washing gear their outdated mining equipment earlier than placing the elements up on the market on eBay or native equivalents.
Some Vietnamese miners have cleaned up their outdated graphics playing cards after ETH merge by bathing them with extraordinarily excessive threat. It is actually their cleansing season whereas ready for the subsequent GPU-minable third coin. (1/3) pic.twitter.com/qnUMWxpyctSeptember 23, 2022
Within the video above it’s considerably startling to see what’s purportedly a Vietnamese GPU miner casually jet washing a number of racks filled with highly effective GPUs. Twitter’s I_Leak_VN shared a group of those intriguing movies at this time. Alongside the movies got here repeated warnings about shopping for used graphics playing cards.
The highly effective jets from this sort of cleansing system can simply trigger potential bodily injury (who’d miss a random floor mount resistor?) or water ingress into locations it may not simply evaporate from. Additionally, thermal paste or lubricating grease might presumably be eliminated too, so watch these followers.
The water allegedly getting used within the jet washing / bathing wasn’t significantly “clear”. It may simply go away deposits behind on the PCB, doubtlessly inflicting injury that would result in brief circuits or different electrical injury as soon as these merchandise are powered up.
In a 3rd video from the identical supply, we are able to see immersion washing getting used on some graphics card PCBs and I/O brackets in a shower of ‘ozone water’ that’s being agitated utilizing an ultrasonic cleaner. Whether or not this can be a second stage of ‘refurbishment’ or cleansing for the jet washed playing cards, or is reserved for older, dustier or grimier playing cards isn’t mentioned. We should point out that there are professionals and fans that sometimes wash element PCBs through immersion strategies, and even in a family dishwasher. These nicely versed on this cleansing methodology are once more very cautious about their water and cleansing components; any impurities or deposits left behind after the wash (and prolonged drying) may very well be detrimental to digital integrity.
Summing up the above, it seems to be like a portion of the anticipated flood of used, ‘like new’ and even some ‘refurbished’ graphics playing cards may very well be susceptible to failure. If the silicon and supporting elements haven’t been confused to inside an inch of loss of life throughout their time mining, they’re then subjected to excessive cleansing to try to make them look field contemporary. Watch out on the market on eBay or your native equal if you end up GPU discount looking. It seems to be like guaranteeing it is possible for you to to get refunds and/or replacements significantly necessary, and a assure from a vendor with a great repute would in all probability be worthwhile too.
