Technically, you are correct. But with this specific motherboard, I can run triple channel using slots 1,2,3,5. I verified that through Gigabyte tech and using MemTest86. The problem I'm having is when I lowered the RAM timings from 9-10-11-28-2 to 8-9-9-27-1, my GFlop when from 50 to 48. I had both settings stable with only minimal changes. I'm hoping someone can explain to me why my computer actually got slower with better RAM timings and "MAYBE" give me pointers on what settings to adjust to make it better... THANKS!!!
