Gigabyte Takes Action to Prevent Cracking in High-End RTX 40 Series GPUs
Reports on the Nvidia subreddit suggest that Gigabyte has introduced revisions to its RTX 4080 and RTX 4090 Gaming OC graphics cards. These new versions feature enhanced PCB designs, specifically addressing the susceptibility to cracking near the PCIe locking mechanism. The redesigned PCB has also been identified in Gigabyte's latest RTX 4080 Super models.
Gigabyte has faced ongoing challenges with poor PCB reliability, dating back to the RTX 30 series. The issue has expanded to affect various board partner models within Nvidia's high-end RTX 40 series GPUs. The increased size and weight of graphics card coolers, a trend since the RTX 20 series, have placed additional stress on the PCBs.
MisinformationALWAYS shared an image revealing Gigabyte's updated PCB design for the revised RTX 40 series. The new design focuses on providing more surface area around the PCIe locking tab, addressing the cracking issue observed in many of Gigabyte's RTX 40 series GPUs. In contrast, the previous PCB design featured a more fragile structure with an extended gap between the PCIe locking point and the bottom of the graphics card.

The effectiveness of Gigabyte's new PCB design in resolving the cracking problem remains to be seen. However, the updated design appears notably more robust than its predecessor. It is hoped that other board partners facing similar challenges with their high-end RTX 40 series graphics cards will adopt this improved design.
The severity of the PCB cracking issue is significant, with nearly every RTX 4090 at risk. Several months ago, a report highlighted a repair technician receiving 19 cracked RTX 4090 graphics cards, rendering them inoperable due to PCB cracks near the PCIe locking mechanism. While the extent of this problem among RTX 4080s or 4090s is not precisely known, it appears more prevalent in pre-built systems that may have been roughly handled during shipping.
For those interested in acquiring Gigabyte's updated RTX 4090 and 4080 graphics cards, the new models are identified by the v1.1 revision. All Gigabyte RTX 4080 Supers come equipped with the redesigned PCB, offering assurance to buyers concerned about potential PCB revisions with Nvidia's latest Super GPU.
