TIA More about : mix match memory dimms FatBurger August 9, 2001 3:55:42 PM Nope, PC133 is backwards compatible. ----------------------- Quarter pounder inside Arrow August 10, 2001 2:30:44 AM Theoretically, there is no difference. But some boards will be the odd ones out. Note that this is very rare.

Spdy_Gonzales August 10, 2001 7:48:50 PM Yes you can mix them, and yes they will run at the slower speed. Sometimes, on older boards they may not work. Is that inconsistent? :smile: <font color=green>I wonder...what is the speed of gravity!<font color=green> :smile: Raystonn August 11, 2001 12:52:49 AM Just continue running yoru bus speed at 66 or 100 (whatever it supports). The memory will run at the slower speed, but it will work. -Raystonn = The views stated herein are my personal views, and not necessarily the views of my employer. = Can't find your answer ? Ask !
