Hi everybody, my first post here so go easy on me.

I was an avid overclocker back in the 300A and Tbird days, but multicore has added a whole new twist for me. I settled on the overclock in the sig after finding that the machine wasn't stable at 3.8GHz at safe temperatures if LinX and Prime95 were run simultaneously. (BSODs, calculation errors, silent data corruption)

Anyway... Setting the QPI link speed in my BIOS has no effect for some reason; it runs an "Auto" scale from 3.2-4.0(!) before switching multipliers. So I'm stuck running 3.6GHz uncore @ 1.45V at my Bclk. But I wonder, since my CPUs are also clocked at 3.6GHz, is there any performance advantage with synchronous operation of the cores and cache/QPI?
