Ocing an old P3 866

[zShowtimez]

I have P3 866 and im gonna work on OCing it. The motherboard and cooling shouldnt be a problem (Epox 3VSA2, Volcano 5 on processor). I can push the chip to 975 easy by boosting the FSB to 150, but the problem that comes up is the RAM i think. Its some generic PC133, 256MB. Theres an option on the motherboard to lower the ram clock 33MHz below the FSB, so I turned that on, didnt help. In fact it wouldnt boot with it on, so i had to turn it off. I think I should be able to get more out of this chip, so any pointers would be helpful.
