I have 4 GTX 570's on a windows 7 machine. According to the programming guide Peer-to-peer memory copy should work on Geforce and Quadro as well as Tesla
Memory copies can be performed between the memories of two different devices. When a unified address space is used for both devices (see Unified Virtual Address Space), this is done using the regular memory copy functions mentioned in Device Memory. Otherwise, this is done using cudaMemcpyPeer(), cudaMemcpyPeerAsync(), cudaMemcpy3DPeer(), or cudaMemcpy3DPeerAsync()
However in order to use it on windows, I need to instal the TCC driver. Can I install the TCC driver for geforce cards on windows?
