Another big difference of the LanParty UT NF4 SLI-DR has to do with the method for setting the SLI mode on the motherboard. Most manufacturers use a daughter card and slot that is used to configure the two 16x PCI Express graphics slots from running in a 16x and 1x mode to a dual 8x configuration. DFI has opted instead to use a set of black jumper blocks that exist between the two slots. This is bit sturdier design than the original daughter card designs.

One of the biggest drawbacks of the SLI configuration for the nForce4 chipset is the location of the it in relation to the expansion slots. In this case, the chipset fan is directly behind the primary 16x PCI Express graphics slot. This means that it is not possible to replace the heatsink fan with a third party solution. It also transfers a lot of heat to graphics card that can impair graphics card performance and overclocking.

In fact, during testing with an SLI graphics card setup, the primary graphics card was typically 5 to 10 degrees Celsius hotter than the secondary card. If the system is only going to have a single graphics card, it is possible to set the motherboard into the dual 8x PCI Express setup and place the card into the secondary slot. This will reduce the number of PCI Express lanes from 16 to 8, but during real world testing there was no noticeable difference in performance.
