I have a 2.4northwood Celeron running at 2.8 with FSB@115. Mem bus is @298mhz. I have had it to 3.0ghz with a 125mhz FSB, membus@333. it runs stable enough for me. Now i know Voltage kills, with all temps under 55 degrees. would upping the DDR voltage say to 2.6 or 2.7 and raise the Core to 2.55v would that give me more performance or jus more heat?? i would think it would but i dont want to fry my memery and cpu. btw i have coolers on my mem.
