Understanding ICES-003 Class B: The Regulatory Guide for Your Graphics Card Drivers
ICES-003 is the Interference-Causing Equipment Standard issued by Innovation, Science and Economic Development (ISED) Canada. It ensures that digital devices like graphics cards do not emit excessive radio frequency noise that could interfere with other electronics.
The 2021 Update: The search for "2021" drivers often stems from ICES-003 Issue 7, which was published in late 2020 and became mandatory in October 2021. This update changed how manufacturers tested their gear, leading to a wave of new compliance labels on products sold that year. ices 003 class b graphics card driver 2021
NVIDIA’s controversial driver that limited Ethereum hashing on RTX 3060 cards also altered PCIe signal integrity. Some users found that this driver caused their monitor’s built-in speakers to emit a buzzing noise—a classic symptom of conducted EMI. A hotfix driver (461.81) reverted the PCIe timing changes, citing “improved EMI margin for Class B environments.”
