The AOpen AX45-4D Max will be the first motherboard which will ship with the SiS 655/963 chipset that allows Dual-Channel operation similar to Intel's Granite Bay chipset.
What is Dual Channel? You might be wondering what kind of enhancement would this new technology do to your system, right? Simply put, we used to have 64-bit memory bandwidth for memory access. No matter how many memory modules have been installed, though capacity added, the speed of access remains the same! From now on, with 128-bit dual channel introduced, it doubles the memory bandwidth up to 5.4GB in advanced 128-bit mode!More information @ AOpen
