pc 2 100

[Brian G]

hello,
I am trying to learn about PC2 100.
Just what it is etc.....
web sites with info would be appreaciated
and any inside info, personal ideas, like switching from PC133 to..(if possible). stuff like that, I have no idea of what the difference is.
Thanks

Peace be with you

Double data rate (DDR) SDRAM does exactly what it sounds like — it doubles the rate of speed at which standard SDRAM can process data. That means DDR is roughly twice as fast as standard SDRAM. While DDR SDRAM chips have been used for some time in graphics cards and game consoles, Crucial Technology was the first factory-direct source of DDR SDRAM modules for hardware developers.

Good explanation Jumby-here is some more detail; since DDR rate " double pumps " the data, you have PC1600 moving data at 1.6 gb's per sec-hence the PC1600 nomenclature. PC2100 moves data at 2.1 gb's per sec, Ditto the name again. Remeber however that just as in PC100/133 specs, if you were to put a PC2100 stick in a system that only ran a 200mhz FSB ( 100 double pumped ) it would only run at the speed of a PC1600. PC2100 is designed for the 266 FSB ( 133mhz Double pumped).

Your system will always run at the maxium of it's slowest component, that's why you shouldn't put a CD player/burner on the same IDE cable as your Harddrive ( unless it's an ATA33 standard itself ) cause it will slow down the data burst rate of your Harddrive.

If you'r interested, SDRAM transfers data at around .8 gb's per sec, i've seen my systems speed improve i'sd say anywhere from 30-40% with DDR memory. It's very much worth the investment. http://www.PCGuide.com/ubb/biggrin.gif
