What sockets can the AMD ISA plug into?
XtremeData ISA’s are only proven in sockets 3 and 4 (the non-IO sockets). If you plug the ISA in the I/O socket, then the drivers for that south bridge will not get loaded. Since the module does not currently support “Tunneling”, it is best to only use our accelerators in the back two sockets. The ISA has the capability to support tunneling, but this feature is not currently supported.
