GPU miners cheat: Watch out for the memory drawn on the graphics cards in use


PSA: Malformed memory chips are a common sign of heavily used graphics cards, possibly previous mining cards. Recent evidence suggests that some vendors attempt to deceive customers by drawing over memory. The paint comes off relatively easily for those examining the GPUs in use.

Two Brazilian YouTube channels have uncovered signs that crypto miners are trying to sell used graphics cards by passing them off as more lightly used than they are now. An amazing new technique is to hide the signs of wear in GDDR memory.

When the GPU is under heavy load for extended periods, such as mining cryptocurrency, heat can give memory chips a yellow tint. Iskandar Souza (below) and TecLab recently Spread Videos that analyze cards that appear to be drawing on those chips. Scraping off the paint revealed the discoloration. Souza’s report compares a new GPU to one with disguised wear and tear.

The past few years have paved the way for such schemes in the graphics card market. Miners are trying to offload GPUs from their platforms that have lost profitability after crypto winter and last year’s Ethereum merge. Although lower mining prices have improved prices in recent months, many cards remain Struggling to get into MSRP.

In this environment, deals on used GPUs are likely to remain attractive to many potential customers. These buyers will likely want to avoid cards from cryptocurrency miners that are more worn than most.

Extensive use and repair efforts are also leaving marks on other parts of the GPU, as seen in Souza’s video. Discoloration around the card’s core and scratches may indicate that the vendor attempted to reinstall it, for example. Missing screws could indicate someone cracked open a graphics card to cover up traces of mining use.

Last year, we reported on a video an offer A miner attempts to prepare GPUs for resale by blasting a rack of them with a pressure washer – a highly undesirable method. Not only can untreated water damage graphics card components, but the force of a pressure washer can also damage them.

However, all of the revamped GPUs aren’t bad. Buyers just need to be careful when buying from third-party sellers on major sites like Newegg and Amazon. Perhaps the safest way to get renewals is directly from board partner stores such as PNY and EVGA (pictured above).
