I was told to never mix PC133 and PC100 Ram
I was told to never mix PC133 and PC100 Ram together.
I just accidentally installed a 256 / PC133 and a 128 / PC100 strip in the same computer and it booted right up without problem. When I grabbed what I thought was the 128 / PC100 to put it in another computer I realized I put in the wrong strip...... Oops..... I thought they could not be used together. These are SDRAM. Then I made another mistake (been one of those days). I pulled the wrong strip before shutting off the computer. Oops, frozen computer. Now they are all in the correct computers and everything is fine. |

There's no issue mixing ram. PC133 can replace PC100 in a system designed for PC100 - the PC133 RAM will just run at the slower speed of PC100. The reverse is not true. *TimDaniels* |

There's no issue mixing ram. Oh ye of little experience... I've been mixing PC133 and PC100 from the outset without issue except on some brand name motherboards. A blanket statement that 'you should never mix ram of different FSB speeds' is incorrect in the majority of cases (and certainly will not kill a computer like th poster implied...unlike yanking modules out of a powered system). You chose to take a personal swipe rather than address that blanket statement. What does that say about you?

Most PC100 modules, especially those sold in the last 6 or 7 years are rebadged PC133, and will run perfectly fine at the higher speed. It's rebadged simply to maintain OEM compatibility. |

That is how all memories (and CPUs for that matter) achieve different speeds. The chips are all the same. The modules are all the same. When they test the chips they either meet the speed rating for the faster parts, or they meet the speed ratings for the slower parts, or they are discarded as scrap sometimes to show up in "bargain" memory I am told. I have never tried to verify the "bargain" memory claims. With older SD RAM the design was pretty solid for both the chips and the boards and there were few incompatibility issues. With newer memory types, the bus speeds are higher and board designs (mostly mother boards rather than the memory modules) were not 100% correct. So you ended up with situations where one brand of memory stick would work and another would not or they wouldn't work together or you could use the first bank or two but with not the last. Basically the DDR memory system design was pretty poor in many respects. This led to a lot of people making up rules like "don't mix the speeds" or "don't mix the brands" and who knows what... DDR2 is supposed to have fixed the system design issues, but I have no first hand knowledge of that. But I bet you don't hear so many "spooky" stories of things not working unless you follow all the made up goofy rules. Actually, DDR runs with higher data rates and has the potential of being worse. But I think they went to point to point data connections which solves a lot of the signal integrity issues. Someone please correct me if I am wrong about this. |

Not having the time to experiment (i.e. "try 'n fry"), I choose to follow the recommendations of companies like Crucial - which tell me that I can count on PC133 working in place of PC100, but not the other way around. As has been pointed out here, PC100 *may*/*might*/ *could* work in place of PC133, but why do the experiment to look for what may be rare and intermittent data corruption when you don't have to? *TimDaniels* |
