Ben's Custom Cases hacked up a DFI NF4 Ultra-D in their latest article and turned this board into an SLI board
Months ago when DFI released their nForce4 Ultra-D series of motherboards, some discoveries were made regarding this board. It was common knowledge that the board had two 16x PCIe slots and a series of jumpers marked "SLI" but the chip was not capable of SLI as it was the nForce4 Ultra chipset. Some people discovered that certain drivers would actually enable SLI operations, but nVidia quickly patched those up and "software initiated" SLI was no longer possible.D-I-Y SLI with DFI: Free Performance?
Reports varied around the web from people who claimed their board could run SLI and others that said it was impossible. I purchased the nF4 Ultra-D for our test rig hoping that it could be modding into an SLI board, but I was quickly loosing hope.
