DDR Info

[goldeagle2005]

Hey
Here's a table I got from MSI's web site

FSB\Memory DDR266 DDR333 DDR400
200 MHz YES YES NO
266 MHz YES YES YES*
333 MHz YES YES ***
400 MHz NO NO YES*

What I want to know is this:
the 200, 266, 333, 400 MHz listed in the leftmose column is the RAM's FSB speed. What does the 266, 333, 400 stand for in DDR266, DDR333, DDR400 ?

Im a bit unclear on that
Thanks

No, the "FSB" is the Front Side Bus speed on the motherboard.The DDR266/DDR333/DDR400 items are the various speeds of DDR RAM available.

However, to get a better idea of what is happening (and so offer the best advice), what motherboard are we talking about here and what is it you are trying to do exactly?

What I wanted to know was what the DDR 266 etc meant. Is that the RAM Module's clock speed? I'd appreciate it if you could give me all info about RAM (What DDR266, DDR333 etc is, what PC2100, PC 3200 etc is.) All technical info there is to know about DDR RAM.

I was talking about the MSI 6712 mainboard.

"DDR266" does indeed refer to the RAM module's maximum rated clockspeed. DD266 means that the module is capable of 133Mhz, which is 266Mhz "double-pumped" (DDR - Double Data Rate).

"PC2100" refers to the module's maximum transfer rate, which in this case is 2.1Gb/s. It's also another way of identifying the RAM module's speed. PC2100 = DDR266, PC2700 = DDR333, PC3200 = DDR400.

Additional information can be found by Googling and looking here. ;)

Thanks. All info clear now.
