NVIDIA GeForce 595.71 WHQL Driver Update: New Issues Emerge for RTX 50 Series

NVIDIA recently rolled out the GeForce 595.71 WHQL Game Ready Drivers, aiming to resolve several problems found in the previous 595.59 WHQL release. While the update addressed earlier concerns such as fan detection and operation, a new set of challenges has surfaced for users of the latest RTX 50 series "Blackwell" graphics cards.

Performance Drops Linked to Voltage Restrictions

Multiple users have reported that after installing the 595.71 driver, their GPUs are experiencing restricted core voltages. This limitation appears to be affecting the entire RTX 50 series, leading to noticeable performance drops across various games and applications. The root cause seems to be a cap on GPU core voltage, which in turn reduces the maximum achievable frequency.

Independent testing by Wccftech highlighted the impact of this change. For example, the MSI GeForce RTX 5090 SUPRIM X previously operated within a voltage range of 1.020 to 1.030 V, achieving boost frequencies around 3,015 to 3,030 MHz during FurMark stress tests with the older v591.86 driver and manual overclocking. With the new 595.71 driver, the same card now runs at a reduced voltage range of 1.005 to 1.010 V, occasionally dipping to 1.0 V. As a result, boost frequencies have fallen below 3,000 MHz, leading to decreased performance and lower power consumption.

Possible Reasons Behind the Voltage Cap

There is speculation that NVIDIA may be experimenting with lower voltage caps to limit GPU boost capabilities. This approach could be intended to reduce power draw and address concerns about the durability of the 12V-2x6 power connector, which has been known to overheat under high loads. However, NVIDIA has not provided any official statement regarding intentional or unintentional voltage regulation in the latest driver release.

User Feedback and Ongoing Discussion

The GeForce Forums have seen a surge in user reports about performance degradation following the 595.71 driver update. Many users are sharing their experiences and seeking clarification on whether these voltage restrictions are a temporary measure or a permanent change. As of now, the community awaits an official response from NVIDIA to address these concerns and clarify the situation.
