Yeah it does make a difference, but not
that much. You're running 50MHz faster, and tighter timings(though he's got 50MHz CPU on you)

...but i suspect there's more to it than that. I'd like to see his memory subtimings(and how "tweaked"...or "untweaked"

his system is...background services,etc.).
Your 1M time looks spot-on for 4GHz... so i think his is a little slow... versus yours being fast/GHz. *** no offense intended to either of you's***
