Graphics card drivers are frequently updated to improve performance, add new features, fix bugs, and ensure compatibility with the latest games and applications. In 2021, several significant updates were released for both NVIDIA and AMD graphics cards, reflecting ongoing efforts to enhance performance and support for evolving technologies like ray tracing, artificial intelligence (AI) enhanced graphics, and improved virtual reality (VR) and augmented reality (AR) experiences.
Some motherboard BIOS updates in 2021 added a or “Spread Spectrum” toggle. This is not a driver setting but works in tandem with the GPU driver. Enable it if you need strict Class B compliance.
If your device was released or used around 2021, it likely uses one of these major driver sets: Radeon RX 580
: Drivers control the clock speeds, voltage, and timing pulses of the GPU. Because ICES-003 applies to any device generating pulses at rates above 9 kHz, the way a driver manages these signals can affect the card’s EMI profile. Instruction Manuals ices 003 class b graphics card driver 2021
The shift to Issue 7 meant manufacturers needed to ensure their hardware and software combination met the new standard.
Which (Windows 10, Windows 11, etc.) do you use?
Enter your GPU series, operating system, and change the "Windows Driver Type" to match your system (Standard or DCH). Graphics card drivers are frequently updated to improve
| Frequency Range (MHz) | Class B Limit (QP in dBµV/m) | | :--- | :--- | | 30 – 88 | 40.0 | | 88 – 216 | 43.5 | | 216 – 230 | 46.0 | | 230 – 960 | 47.0 | | 960 – 1000 | 54.0 |
Look for the ICES-003 statement on the product's packaging, in the user manual, or on the card itself. It will indicate whether it is Class A (commercial) or Class B (residential). If you live in a home or apartment, ensure your card is Class B.
If you are looking for a "2021 driver" for a device with this label, you are likely looking for the official manufacturer drivers (NVIDIA, AMD, or Intel) for a card produced or sold around that time. What is ICES-003 Class B? This is not a driver setting but works
