Nvidia recently released the GeForce Game Ready 595.71 WHQL driver package, focused on bug fixes and system stability for its global consumers. Entretanto, the update brought a silent technical modification that changed the energy behavior of RTX 50 series graphics cards. Independent Testes confirmed that the software imposes a new ceiling on the voltage of the graphics core, restricting customization capabilities.
The change directly impacts the community of enthusiasts and advanced users who use overclocking techniques to extract maximum performance from hardware. The restriction was mainly observed in high-performance models, such as the RTX 5090, which now encounter barriers to reaching the operating frequencies recorded in previous versions of the driver. Throttling prevents the component from receiving the power necessary to operate above factory defaults.
The scenario generated debates in specialized forums, since the change reduces the room for maneuver for fine manual adjustments. The energy containment measure acts automatically, regardless of the settings attempted by the user, blocking the full potential of the manufacturer’s most modern graphics chips.
Technical differences in energy management
Comparative analyzes between the current version and the previous driver, identified as 591.86, show a clear reduction in the permitted electrical parameters. The hardware, which previously operated fluidly between 1020 V and 1030 V during manual adjustments, is now forced by the system to work in a lower range, oscillating only between 1005 V and 1010 V. The Essa difference creates an immediate physical bottleneck for graphics processing in high demand situations.
In practical bench tests, voltage limitation resulted in the RTX 5090’s inability to maintain frequencies above 3,000 MHz stably. Mesmo When using third-party software to force higher values, the protection mechanism built into the new driver acts instantly to reduce the voltage, keeping performance contained within conservative limits established by the update.
Impact on custom models and partners
The restriction imposed by the software also affects cards developed by Nvidia partners, such as the premium lines from ASUS and MSI. Proprietários of these models report that even maximizing the power limits in the settings, the voltage curve is unresponsive, suggesting that blocking occurs at a deep level in the driver. Isso ignores robust hardware specifications designed by third parties specifically to support more intense workloads.
The RTX 5080 model showed similar behavior in tests, failing to reach the 3,230 MHz peaks that were accessible with the old drivers. Popular Ferramentas settings, such as the MSI
Driver security and rollback
Experts in the technology sector point out that reducing maximum voltage can be a preventive measure to ensure the long-term integrity of components. The main hypothesis is protection of the 12V-2×6 power connector against overheating in excessive load scenarios, although Nvidia has not issued an official statement detailing the specific technical reasons for this sudden change in power management.
In response to the limitation, many affected users chose to downgrade, returning to using version 591.86 WHQL. Essa rollback allows you to regain full control over the voltage and frequency of the cards, although it forces the user to forego the latest optimizations and bug fixes intended for games recently released on the market.
