Where can I find out how PC2700 got it's name?
I understand 333MHz DDR SDRAM (double data rate of the system bus speed - on the up and down cycle in the current PowerBook case 2 * 167 = 333MHz), but what is the correlation to PC2700 ... and PC2100 for that matter?
Thanks.

Thanks for the Google link
(or, if someone has a better idea of what to type into Google to find this answer please share)
TIA.
google "PC2700 means"
The first result is very detailed. Here's a brief quote from it:
Naming Conventions
Module vendors use the PC-xxxx, which signifies the module data rate in MB/s (Mega-Bytes per second). Memory vendors adopted the DDR-xxx that signifies memory data rate for each pin in MHz (Mega-Hertz).
Module Data Rate Memory
Data Rate Maximum Bus Speed
PC1600 DDR200 100MHz
PC2100 DDR266 133MHz
PC2700 DDR333 166MHz
PC3200 DDR400 200MHz
Table 1: Data Rate and Bus Speed
For example: 2GB Stacked PC2700 Registered DIMM has the capacity of storing about 2 billion words (2GB) of data. PC2700 means:
(a) The transfer speed is 2.7 billions words per second. It can transfer the whole content of its memory in less than 1 second.
(b) It can be used in systems with any bus speed up to 166 MHz. i.e. 100, 133 or 166 MHz.
Sometimes I wonder if we should have to pass a test like the driver's license exam to use the internet.

Ahhh.... I see, I should have typed PC2700 "means"

I have no witty retort for this...
still - thanks anyway (now I'll know for next time)
