i have a PowerColor 6700xt Red Devil, On the manufacturer's page it says that the OC boost frequency is 2622 Mhz, but in the Adrenalin driver it is set to 2649 Mhz by default, is that normal?
The PowerColor 6700xt Red Devil graphics card has a base clock speed of 2622 MHz, as stated by the manufacturer. However, the Adrenalin driver software sets the maximum frequency that the GPU can reach, called the "boost frequency", to 2649 MHz by default. This is common for graphics card manufacturers to set higher frequencies in software for improved performance. It's important to keep in mind that this can increase the power consumption and heat of the GPU, so it's important to monitor those to prevent damage to the card.
