The 66 and 100 denotes the megahertz that the RAM runs at. Current Intel Celeron processors run at 66mhz and current P3's are either 100 or 133mhz. However, most motherboards allow you to use PC100 RAM with Celerons (forcing the RAM to run at 66mhz). But alas you cant use PC66 RAM with P3's. Also, some older motherboards actually require you to use PC66 RAM and cant handle the PC100 RAM regardless of CPU. |

That's some good information above. PC66 has a little bit of a slower response time that PC100. And I believe it has to have at least a 300mhz cpu or there abouts to work. Make sure your board will take PC100 and if so go for it. PC133 is out also. PC100 has a response time of 8ns and PC133 is 7.5ns. I personally don't think 133 is worth the price difference, right now.

Correction: PC100(not PC66) needs a 300mhz or faster I beleive. |

Pentium II 333 or lower use PC66
Pentium II 350 or higher need PC100 ram |

Actual memory speed depends on motherboard data bus clock speed, usually settable. The above processor/speed combinations are typically correct when things are optimized, but if you have jumpers to set the bus speed you can sometimes control what actually happens (if you want to for some strange reason). As long as your memory will run at your selected speed you can run. |
