FSB problem!!!!

I have an AMD Athlon XP3000+ CPU, and just installed it in my new mobo. I can't run it at 333Mhz ( Frequency of 166), because evertime i'm about to get to the Windows XP screen (the black/loading screen) it restarts. Now i switched it both 133MHz and 100Mhz and then it works. When its at 166 the temp doesn't go above 55F, so i don't think this is a heating issue.....but then what do I know???? So would some of you more experienced people please, PLEASE help me. I don't know what to do.

 

Does your ram support 166 FSB ( 333DDR ) ???? Make sure your running stock memory timings....

 

took out my one stick of PC2700, and left my two stick of PC3200 in......it works, thanks

 

well PC 2700 is DDR333 so it should work....maybe check for a 1:1 memory:FSB ratio or maybe thares a setting to force DDR333 .... My gess is some how its trying to run DDR400 and the DDR333 stick wont do it....
