Run that Orthos test and get back to us.
Just some advice for the longrun, in case you find you have more headroom in your chip (which you likely will): make sure that you keep your fsb and memory running 1:1 ratio (look in CPU-z) (also do you have the latest version of CPUZ? The clocks are off, from your dropped multiplier)
you can also run a higher fsb with a lower multi (which it looks like you are doing), Conroes get quite a boost from having higher bus speeds.
but your maximum performance will always be the highest FSB you can acheive with a 1:1 ratio.
