All that will happen is that any PC 133 modules will only work as PC100, thus slowing down your computer. It's better to use all the same speed modules.

In rare cases you will get real errors, not just a slower system. But it is very rare and varies from board to board and chipset to chipset.

If your main board is designed to oscillate the memory at 133 and does not have the ability to set it lower (100), you can experience computer lockups and/or corrupted data even including a scrambled file table.

Also, you could even overheat the memory and destroy the chip.

Most older machines have the ability to autosense or manually choose a setting of 100 or 133 in the BIOS. This feature is less prevelant in your big branded systems.

It should be understood that the oscillation speed of the memory is set by the board; the memory has no oscillator of its own. It can be over/underdriven as easily as driven at proper speeds. That is all determined by the board, not the memory chip.

another thing, if you try putting in a slower ram stick in, remember to ALWAYS put it in the FIRST SLOT before any other sticks!
