From this it's clear that DFI didn't follow the nVidia reference design and further proof of this is that the little piece of PCB that most SLI boards use to change between SLI and none SLI mode is missing. Instead DFI is using six blocks of jumpers that have to be moved to change to SLI mode. The problem with this is that the jumper blocks are quite hard to remove, even with the included tool. As the tool hasn't been specifically designed for removing jumpers - it is a BIOS chip removal tool - it takes time and patience to remove the jumper blocks. However, re-fitting them is easy enough and it's not a task that you'll perform more than once or twice in the lifetime of the board anyhow - unless you review graphics cards for a living.
