RAM Question...

merlinxi · Aug 17, 2004, 01:17 PM

Why is ram named like this:

DDR400, Obviously means it's 400MHZ speed.

But why is it PC3200 after that, what is the purpose of giving it a different name with the same purpose. I can't think of anything else, unless it has to do with binary. Please enlighten me

Its called PC3200 because it gives up to 3200MB/s of bandwidth

And on top of that, the actual clock frequency is 200MHz. What a nice world computer business can be...

So in other words, 400mhz is the bus speed? and the clock speed is 200, and the bandwith is 3200?

In a nutshell, yes, as long as you remember the MHz, and MB in there.

i kinda knew all of that, except for the 3200 part. all you need to know is this:

3200 is faster than 2700

Heh, I had a friend who assumed higher timings on ram was better, because of the higher numbers.

the 400 refers to how many transfers per second are taking place. the memory runs at 200MHz, but since it is DDR (double data rate), it does 2 transfers per clock, hence DDR400.

and yes, technological naming conventions can be very wacky

good example fo tech naming conventionas... AMD Athlon 1600+ (or the model numbers)... they pose a interesting idea.. but are flawed....

Need a different system to gage cpu speed.... ghz don't work and gflops don't either....
