And I think this model used DDR and not DDR2.

I was asked by a friend to install Windows 7 into a DELL Demention 3000. It had 256mb of Ram aand needed 512mb mininum to install Windows 7. I have several sticks of DDR2 and tried to insert them into the DIMMS they won't match up with the single notch. When I place the old memory and new memory side by side there is about 1/8 inch differance in the alignment slots. Do DELL computers use a non standard DDR2?
