This can be a rooted Word that purchasing a used GPU, particularly one which has been used for cryptocurrency mining functions, is mostly a foul thought. However whereas shoppers understood the reality, that did not cease miners from discovering new methods to promote their broken items.
For instance, the most recent pattern rising from previous miners in China promoting used mining graphics playing cards is to color the graphics reminiscence to make the playing cards seem like model new. The deception was noticed by Brazilian Techtuber Iskandar Souza, who runs the YouTube channel Techlabs, and his technician good friend Paulo Gomes.
Souza’s investigation of your complete scandal is mainly a how-to in detecting GPUs which have been explicitly used for mining. To start with, he states that among the fundamental options of used graphics playing cards stay the identical; Lacking stickers and screws that have been clearly tampered with with a screwdriver are nonetheless good indications that the GPU has undergone some type of change.

As for “refreshed” graphics reminiscence, Souza says one of many largest indicators would be the yellow tint within the card’s reminiscence and GPU cores. Apparently, this yellow tint is the results of miners resoldering previous or faulty elements onto new boards. As well as, a yellow tint seems because of extreme warmth from extended use. Regardless of the case, Souza says the yellow tint is conclusive proof that the graphics card has been used for mining earlier than.
On one other word, this wasn’t the primary time Souza and his crew had encountered used mining GPUs offered with modified elements. In one other video, Techtuber found that some firms in Brazil have been unknowingly promoting modified graphics playing cards; The GPUs themselves have been seen utilizing a distinct shade of epoxy, and as soon as once more, a yellow tint across the PCB was seen across the core.
Regardless of all that has been stated right here, it is also good follow to not bounce to conclusions simply since you see a yellow tint in your graphics card part. As we talked about, this tint is commonly brought on by extended use in addition to put on and tear, which implies the cardboard is closely used for gaming, not mining. It is also widespread follow amongst board companions to decode elements on a GPU, because it helps them get monetary savings on utilizing costlier elements.
