What are the hardware requirements for FPGA mining?
Currently there are no known specific hardware requirements for FPGA mining beyond basic requirements for GPUs. That is, a basic CPU, minimal ram, minimal disk, and x1 PCI-E 3.0 connectivity.
Is using a 2.0 PCI-E out of the question or can we get by with one? Would this reduce the cards overall effectiveness and by how much?
One of our engineers is testing on PCI-E 2.0, but we have no idea how it will behave in mass deployment or with variations of motherboards.
