whenever you change ram timings and fsb always check your ram for errors with -Memtest86-
its a util you run from a floppy disk at bootup and if your memory aint 100% stable it will tell you.
a memory can work 100% in windows and even games even if its not 100% error free but it wont last as long (obviously). so therefor its good to test the memory with memtest86 so you REALLY know if it actually is 100% error free

i personally ran my memory at some timings and fsb for a few months before i found out with memtest that my memory was not 100% error free. and there i was thinking it was perfect and all
