In a recent video by Northwest Repair, it was revealed that a modified RTX 4090 graphics card has been completely discarded due to inadequate heat dissipation and the use of substandard power supply components. This particular card, boasting an impressive 48GB of memory—double that of a standard RTX 4090—ultimately succumbed to the perils associated with the modification, rendering it beyond repair. While past instances have seen successful graphics card repairs, it's evident that not all modifications can yield positive outcomes.
