Hey, I am currently debating about getting into the Opteron club. Cos my local stores currently don't have 146s in stock, all I can get are cabne & cabye 144s. The seppings are fine, but it seems I cannot run my cpu at high chipset speeds on my board. Even though my K8N Neo2 P.E. supports HT speeds of up to 450, any attempts I tried with my current CPU to run around 300 MHZ HT (with low dividers and low mem settings of course, just to test) failed miserably. I already tried upping the vga-voltage as my mobo doesn't have individual chipset voltage. So how does it work? Is it pure luck? Am I missing something? As far as I understand it, it shouldn't make a diff if I run my setup @ 9x200 MHZ or 6x300 MHz, as long as I make sure the ram runs accordingly, right? Please help me out, I know those cabne Opterons will run 3GHz, but it's no use if I cannot crank up my bus-speed! Cheers!!!
