more than 846mhz from celeron 600

im looking fer more speed,, i got an abit bx 133 raid mb,, and a celery600 cpu that wont go over 846 mzh,, it'll run fer 30mins or so before crashing,, Do i need to get a better cooler than the standard fan on the cpu?????

The stock Intel fan fine for default speed but not that great for ocing. An Alpha Pal 6035 would do a great job and not drive you insane like a H/F with a delta 38. What do you have your voltage set at? If you haven't increased the cpu voltage from stock this would be why you can't clock any higher.

did you up the core voltage?

if you have the stock cooler, get a new one. The Pal6035 would be great for you. You may need up your core voltage, but wait and get a new hsf.
