In BIOS I have found an option that lets me choose between Ganged or Unganged for the CPU's memory controller. I have an AMD Phenom II X4 CPU. What is best for FS? Ganged or Unganged?

I had google it hehe, but looks like gaged mode will benefit multithreaded tasks by spliting the memory controller in two (2x64b) while unengaged gives single threaded applications an extra memory band width to work with (1x128b)Just test both and let us know how you do please. I don't have my phenom anymore to test it
