Just looking for some confirmation that 184 pin 266mhz DDR RAM is the correct kind for a new dual 867 Powermac.

My online vendor of choice here in Canada only has 266mhz listed, no mention of PC2100, where as the Apple site says PC2100 - but no mention of 266mhz.



Cheers!

    In the best of my knowledge I believe that PC2100 DDR is 266MHZ DDR. Id say about 99.9999999% sure.

    PC2100 unbuffered is the correct kind (I think). PC2100 DDR RAM is actually 133Mhz, but since data transfer happens on the rising and falling edge of the clock is an effective 266Mhz. This is why it is called DDR (Double Data Rate).



    This may help you with DDR vs. RAMBUS memory:
