RADEON 7870 TWIN OPENCL DRIVER INSTALL
When you have the drivers installed correctly and didn't install BOINC as a service, you can check in the BOINC messages if your GPU is detected correctly. This may be an option in the driver installer (mostly in the case of Nvidia drivers, and it's hidden away in a non-obvious place so read all the options carefully), but it may also require you to uninstall the previous drivers via Device Manager or Uninstall a program. Wherever, try to make a clean installation of the drivers. So it is better to use the drivers from the GPU's manufacturer, being AMD (or ATI), Intel or Nvidia: It's also that a lot of the components are open source, a thing that Microsoft doesn't like, and most of these components are direct competitors with things that Microsoft makes:
Game and 3D graphics performance of the AMD Radeon HD 7850 can be.
This model has the maximum power draw of 130 Watt. The GPU supports PCI Express 3.0 interface, and needs 2 slots on the motherboard. The memory is clocked at 1.2 GHz, which gives 153.6 GB/s memory bandwidth. This is done to make the drivers be available for a wide range of hardware. The Radeon HD 7850 embeds 2 GB of GDDR5 memory, utilizing 256 bit bus. While Windows will probably install drivers for your GPU, these drivers are usually lacking the necessary components to do calculations on that hardware.
