RAM question - can I use both PC100 and PC133 RAM ?

[lt123]

If my motherboard accepts PC133 RAM, can I use one stick of PC133 RAM and one stick of PC100 RAM at the same time?

If the bus is 100Mhz the 133Mhz should work, if the bus is 133Mhz the 100Mhz unlikely will not work.

I've got the Abit Kt7-RAID motherboard.

Thanks
