Is pc133 RAM necessary for 133 MHz FSB?

[Shooters]

I have a Pentium III 700 MHz that I want to try to overclock to 933. I have 2x64 mb of pc100 RAM. My question is, is it necessary to use pc133 RAM to accomplish this overclock? The only reason I ask this is because I saw a post from a guy who said he had overclocked his Intel cpu from 700 to 1050 and he had pc100 RAM listed in his specs. Does the RAM have to be equal to or higher than the FSB in order for it to work? Also, Sisost Sandra shows that one of my sticks will do CAS2 at 100 MHz and CAS3 at 125 MHz and the other will do CAS2 and CAS3 at 100 MHz. Is Sisoft a reliable source or is it just being conservative?

Thanks,

VIA chipsets will allow a 133fsb and a 100mHz memory bus.

My Mitsubishi 64meg PC100 ram 8ns works fine at 133 and 140mhz at CAS3.

Ok, now for a post that actually attempts to answer the question:

Yes, you can sometimes run a 133FSB without RAM that is labeled PC133. Yes, the RAM does have to be running at 133 on an Intel setup. However, you can oftentimes get your RAM to run faster than its specs, much like the CPU. If it does not work, you can always try to tune it down to CAS3 too. This will allow the RAM to run at a higher speed, but have lower performance at that speed.

Hope this answers your question.
