What exactly do you mean? Look, you should be able to set the FSB independently of the memory clock. Also, most newly manufactured PC2100 nowadays should be able to do 166MHz. If the CPU jumped up to 100C, I think you must have done something wrong. Use programs like memtest and goldmem to test memory stability. Use CPU burn or similiar to test CPU stability.With 133 jumpers set I tried increasing the speed to 155/380 - the CPU jumped up to 100 degrees C and crashed spectacularly. I'm surprised it still works.
