Is There a Difference between DDR and DDR2 RAM?
My computer flat out needs RAM, and I have a 512MB DDR stick lying around, but I think my computer requires DDR2, is there a difference in memory type that will restrict me from using the DDR on my computer? I don't want to mess up my computer or anything 
I have a Dimension C521 btw.
Hi there:
Here are the differences of DDR2 over DDR:
1) Double the data rate
2) Double the bus rate
3) Lower voltage (2.5v for DDR and 1.8v for DDR2)
and so much more.. Here's the full list:
http://www.overclockercafe.com/Articles/DDR_vs_DDR2/
And as for your Dell question, your model has specs as follows:
Up to 4GB* Dual-Channel DDR2** SDRAM (533MHz)
* - The total amount of usable memory available will be less than 4GB, depending on actual system configuration
** - Dual-Channel memory requires 2 each of the same capacity memory DIMMs
For more info on your model # check here:
http://www.dell.com/content/products/productdetails.aspx/dimen_c521?c=us&cs=19&l=en&s=dhs#tn3
From what i read on that site, your model supports only DDR2 memory chips not DDR since as stated above, the voltages are different between the two chip types.
Hope this helps!
