Transitioning the Ethereum Blockchain from Proof of Work to Proof of Stake. mergeeffectively meant cryptocurrency mining with consumer graphics cards no longer profitable. Gamers have been waiting for cheap New and used GPUs are becoming the norm, according to a series of videos posted on . Twitter by I_Leak_VN.
Some Vietnamese miners cleaned up their old graphics cards after ETH was merged by exposing them to very high risk. It’s just their cleaning season while waiting for his 3rd coin that is next GPU minable. (1/3)pic.twitter.com/qnUMWxpyctSeptember 23, 2022
In the video above, it’s somewhat surprising to see a alleged Vietnamese GPU miner nonchalantly jet cleaning multiple racks of powerful GPUs. His I_Leak_VN on Twitter shared a collection of these interesting videos today. Alongside the video was a repeated warning about buying a used graphics card.
A powerful jet from this kind of cleaning system prevents potential physical damage (who misses random surface mount resistance?) and water intrusion where it may not readily evaporate. can easily be caused. Also, be careful with the fan, as the thermal grease and lubricating grease may come off.
The water allegedly used for jet washing/bathing was not particularly “clean”. Deposits tend to remain on PCBs and can cause damage leading to short circuits and other electrical damage when power is applied to these products.
In a third video from the same source, you can see dip cleaning being used on some graphics card PCBs and I/O brackets.ZeOne water that is being agitated using an ultrasonic cleaner. Whether this is the second stage of “refurbishment”, cleaning of jet-washed cards, or reserved for old, dusty, or dirty cards is not discussed. It should be mentioned that there are experts and hobbyists who use the immersion method to clean component PCBs. household dishwasherThose familiar with this cleaning method are very careful with water and cleaning additives. Impurities and deposits left after cleaning (and prolonged drying) can adversely affect electronic integrity.
Summarizing the above, it seems that some expected second-hand “as good as new” graphics cards, or even some “refurbished” graphics cards, may be prone to failure. If the silicon and the components that support it haven’t been stressed to the brink of death during time mining, they undergo an extreme cleaning to try and make the box look fresh.Watch out for eBay or your local equivalent when you GPU bargain huntingIt seems particularly important to ensure that you receive a refund or replacement. A warranty from a reputable seller is also probably worth it.
