Yes, there are known issues with installing multiple graphics cards. The most common problems are compatibility issues, power supply issues, thermal issues, and driver issues.
Compatibility Issues
The most common compatibility issue is that when utilizing multiple graphics cards, the cards must be of the same type or architecture. Also, the cards should have the same amount of onboard video RAM. Even when the cards are of the same architecture, it is important to make sure that the cards can work together without any issues. This can be done by researching the manufacturer’s website for compatibility information.
Power Supply Issues
When using multiple graphics cards, a powerful power supply will be required to ensure proper performance. Most modern graphics cards are power hungry, which means they require plenty of wattage to operate correctly. If the power supply is insufficient, the graphics cards may not perform properly or could become damaged.
Thermal Issues
Installing multiple graphics cards can increase the overall system temperature significantly. This is because multiple cards generate more heat than a single card, and therefore require more cooling. If the system is not properly cooled, the graphics cards can overheat and become damaged.
Driver Issues
In addition to the hardware compatibility issues mentioned above, driver compatibility is also an issue when installing multiple graphics cards. Different graphics cards require different drivers, so it is important to make sure that the correct drivers are installed for each card. If a driver is incompatible with a card, it can lead to instability issues or poor performance.
Overall, there are known issues with installing multiple graphics cards. It is important to research compatibility issues, make sure the power supply is powerful enough, properly cool the system, and use the correct drivers for each card. Doing so will help to ensure that the graphics cards will perform as expected.
