Can a motherboard with an 815E chipset use both PC133 and PC100 memory simultaneous?

The memory runs at the speed of the FSB. Therefor if the FSB is 133MHz the pc100 ram will more than likely burn out. I do not know what effect using pc133 ram with the FBS at 100MHz; although obviously you won't get the rams full potential.

Your memory speed should be at or above the speed of your FSB for your processor. If the motherboard allows you to run the processor:RAM at 4:3, then you can use a 133mhz processor and PC100 RAM. Usually, mixing RAM is fine, but in some rare cases, you might have some problems.

if you are not planning on oc'ing your bus speed, you can mix pc-100 and pc-133. some pc-100's can be oc'ed to 105 or even higher. but my pc-150 and my pc-100 are working fine at 100mhz bus speed.
