Can anyone tell me what 266MHz DDR RAM equates to in PCxxxx memory terms? Its my first time with a DDR MB (yes, I'm a RAMBUS snob! ;) ) and I need some RAM...

Cheers.

DDR266 should be PC2100, DDR333 would be PC2700

just to complete the list:

DDR400 is PC3200

Bandwidth formula : Frequency(1) * bus width in bytes
MHz * bytes = MBytes/sec
here : round to hundred ( Frequency * 8 )

266 * 8 = 2128 => PC2100
333 * 8 = 2664 => PC2700
400 * 8 = 3200 => PC3200

(1) or rather equivalent frequency since DDR400 is really running at 200MHz.
