One of the most interesting features of the nForce 4 SLi Intel Edition is that it has native support for 667MHz DDR2 memory. This is not yet a ratified standard, but Corsair is already offering memory which will run at this speed and faster. The new Twin2X CM2X512A-5400UL modules we were sent to test the GA-8N-SLi Royal with worked flawlessly at 667MHz on a 1066MHz bus with a 3.73GHz Pentium 4 Extreme Edition CPU.
