celeron II 850 @ 133x8.5 @ 1.85volts

rock solid until now..
just wana ask something. i jsut wana know if my voltage is ok. though its running solid even for hours of games, i have obsrved if i try to up the FSB to about 135-136 my computer would become unstable. but increasing my voltage to 1.9 seems to perform ok again. so if ill jst stay with 133, should i worry about my voltage having a little allowance incase theres a fsb change?
also im planning to use a pentium3-100FSB-coppermine soon for experiment.. what possible speed should i get to be able to safely reach 133FSB @ a decent voltage?
thanks for this over-age topic
