Heheh...yeah, I knew that overclocking varies big time.
My Celeron 400 could barely hit 525, but my celeron 366 could run at 600 just fine.
Well, defaults are 333mhz memory clock......so I'll tinker with it once I get my slot-fan replaced by 3dcool.com AGAIN! (don't buy the sleeve model...they suck...fail after 3-6months...).
