Question
I have installed a GRID K340 on 1028GR-TRT. I found the GPUDirect P2P (Peer-to-Peer) test failed. Is there a fix for this problem?
Answer
For the failure by running GPUDirect P2P, pls confirm "ACS Support" has been disabled under BIOS.
Then, re-run the test, should be able to pass.

Path: Advanced -> Chipset Configuration -> North Bridge -> IIO Configuration -> Intel VT for Directed I/O (VT-d) -> ACS Control -> Enable / Disable.
