NVIDIA GeForce v595.71 Drivers Reportedly Restricts Voltage on RTX 50 Series GPUs

NVIDIA released its GeForce 595.71 WHQL Game Ready Drivers yesterday to address issues with the previous 595.59 WHQL version. However, troubles don’t seem to be over yet, as reports are coming from multiple users running the latest driver that the new installation is restricting GPU voltages across the RTX 50 series of “Blackwell” graphics cards. As multiple reports point out, the v595.71 driver is causing users to see a significant performance drop across multiple titles, all stemming from the capped GPU core voltage that is reducing the frequency. Wccftech testing has confirmed that the MSI GeForce RTX 5090 SUPRIM X used to run at a 1.020-1.030 V range, resulting in about 3,015-3,030 MHz in FurMark stress-testing using the older v591.86 driver with a manual overclock applied.

However, without a change in settings, the GPU now runs at a lowered voltage range between 1.005 V and 1.010 V, with occasional drops to 1.0 V. This has resulted in boost frequencies that are below 3,000 MHz, degrading the GPU performance while also lowering power usage. The reasoning behind this might be that NVIDIA is experimenting with lower voltage caps to limit what the GPU is capable of boosting to, so it can draw less power and prevent the fragile nature of the 12V-2×6 connector from overheating. Yesterday’s launch of the GeForce 595.71 WHQL Game Ready Driver mentioned that the previous driver issues were resolved, which included fans not spinning or not being detected at all. However, with…
