ICES-003 is the 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.
ICES-003 (Interference-Causing Equipment Standard) is a Canadian regulatory requirement that sets limits on radio noise emissions from digital apparatus. Class B applies to equipment intended for residential environments and therefore has stricter limits than Class A (commercial/industrial use). In 2021, manufacturers and system builders continued to navigate ICES-003 Class B requirements when designing and certifying graphics cards, including considerations related to driver software because drivers can affect device emissions through timing, power management, and signal behavior. ices 003 class b graphics card driver 2021
What Brand X discovered—too late—was that their “Class B optimized” driver actually made interference worse for real-world users, while passing lab tests with flying colors. In a shielded test chamber, the spread spectrum routine looked beautiful: a smooth noise floor, no sharp peaks. In a cramped apartment with a cheap power strip and a microwave running? Pure chaos.

Look for the manufacturer logo (ASUS, MSI, Gigabyte, etc.) or the GPU chip name (Nvidia/AMD) on the card. Once you have those names, you can easily locate the correct 2021 driver packages on the official support sites. Class B applies to equipment intended for residential
While the term often confuses users into thinking they need a "Class B driver," the reality is simpler: your graphics card needs a standard manufacturer driver from companies like , which happens to comply with these safety standards.

In February 2021, AMD’s Adrenalin 21.2.3 introduced a “Rage Mode” preset for RX 6900 XT cards. This preset increased memory clock by 8% and disabled spread spectrum on the memory controller. Users reported interference with nearby Bluetooth devices and wireless keyboards. AMD quickly released 21.3.1 with a note: “Resolved excessive EMI on memory bus; restores ICES-003 Class B compliance.”
