Is PC-133 Memory Downward Compatible with 66 Mhz Bus?

[franco46]

I already have successfully used PC-100 memory with my older computer which has 66 Mhz bus. Will PC-133 memory work as well? Thanks for any help you can provide.

It will be fine.

[LordPolo]

it will work fine, although having lots of different types of memory in your computer can slow it down. (not saying it will, but it can)

It will work but at the same time it's really pointless to have PC133 run at 66 mhz.

Confirmations, That is a go for launch.

just adding my part :)

yup, will work (but methinks it's a sort of a waste tho)
