Mainboards powered by NVIDIA nForce4-series chipsets are entering mass-production now, but not all of them are capable of the feature quite some end-users want most of all – Multi-GPU SLI capability. Still, some mainboard makers seem to know how to transform less expensive NVIDIA nForce4 Ultra into NVIDIA nForce4 SLI media and communication processors.

“It really did not come as a surprise that nForce4 Ultra and nForce4 SLI are the same chipset with some capabilities in Ultra turned off. We have seen many cases over the years in which a manufacturer has one CPU-die or one chipset come off a production line, which are then differentiated with laser cuts or some other means of controlling speed or capabilities. What did come as a surprise is how very easy it is to reverse the process - to turn the nForce4 Ultra into the higher-priced and better-performing nForce4 SLI. This is an extremely easy mod for almost anyone,” claims AnandTech web-site, who has find a way to transform NVIDIA’s nForce4 Ultra into fully-fledged nForce4 SLI and even managed to run numerous benchmarks on such modified system.
