SDR Ram & DDR Ram 'the 'ol switcherooo'

[AndreL]

Can SDRam and DDRam be switched also does DDR have double the accesing time compared to SD Ram.

[bombledmonk]

No they are not compatible. And for the sake of simple explaination DDR can do twice as much per clock cycle as SD RAM

[AndreL]

I read or heard some where that a MB can be configured to accpet both.
Is that ture.

[bombledmonk]

Only if the mobo has separate slots for both. The Sticks of Ram physically different.

[nunyadam]

^ that and you can only use one type at a time in the motherboard.

Yes, what nunyadam said. The two are electrically incompatible (different voltages) and a board will not boot with both types inserted.
