- Nvidia’s 595.71 driver broke overclocking for graphics card users
- The driver limited GPU voltages, leading to underperformance
- Nvidia has just released a hotfix that addresses the issue
Normally, undervolting your graphics card requires plenty of careful tinkering, benchmarking and adjusting in order to get everything precisely right. It’s not something that is forced on you or comes about unexpectedly, yet that seems to be exactly what happened to many Nvidia customers who upgraded some of the best GPUs to the company’s 595.71 driver. Fortunately, although it had an impact on real-world gaming performance, a fix is now available.
The issue was reported by VideoCardz, with the outlet noting that early feedback from the 595.71 driver had included reports of “core voltage and boost behavior changing, with many claiming a ceiling around 0.95 to 0.975V and clocks that stop around 2,955 to 2,985MHz, or around 3,000MHz, even after applying manual overclocks.”
In other words, users’ overclocking abilities appeared to be limited by the software update. This apparently wasn’t in evidence before the customers installed the 595.71 driver. While the problem didn’t appear to be limited to one graphics card in particular, it did only seem to affect those from the RTX 50 series.
Users were not happy. On the official Nvidia support forums, for example, user bloodknight2012 said their custom overclock was “totally…
