Backward Compatibility???

[moboteaser]

I dont understand this concept... when a memory chip can be backward compatible from one speed to another. For example, a pc2700 can be backward compatible to a pc2100. How is that?

A little secret here. PC2100 memory and PC2700 memory aren't really different things per se. They're both ddr memory, its just that the PC2700 stuff is RATED to handle frequencies of 166mhz (DDR333), and PC2100 is specified for 133mhz (DDR266). You could run either at either speed.

Since the PC2100 isn't intended for 166mhz, it'd probably fail. However, running the PC2700 at 133mhz (PC2100 speed) isn't a problem, you're simply not using all of it's potential.

Iamgine you get a Porche, and your friend gets one identicle except for his has a turbo. Both will cruise at 70MPH down the freeway, but his will go faster at a race track than yours. Does that mean his isn't backwards compatable to 70MPH freeways?

well say i have a pc2100 and a pc2700 in the same system will it work together in peace? like some pc100's and pc133's can?

Sure, but your mobo will make them both run at 133mhz (PC2100) so you won't get the full potential of that PC2700. Depending on your CPU that may or may not actually matter.
