    HEXUS.guide: DDR and DDR2 Explained

    DDR stands for Dual Data Rate and is the replacement for SDRAM. The best analogy we have come across for how DDR works is: If the memory is visualised as a bicycle pump, SDRAM “pumps” push data into the “tyre” each time the barrel of the pump is pressed down, whereas DDR pushes data both on the downstroke and the upstroke of the barrel so filling the “tyre” at twice the speed.

    Re: HEXUS.guide: DDR and DDR2 Explained

    Great article! Now I have a question:

    I have a couple of DDR2 PC4300 modules at 1 GB per module installed on my computer, which gives it 2 GB of total RAM. I took the old modules that I had (256 MB DDR PC2700 module x 2) from that system prior to installing the new modules. Is it possible for me to put those old modules back into my system by using those 2 empty slots that I have (my computer has 4 total slots for memory) without causing my system to crash due to incompatibility or memory issues? I feel that the old modules are just sitting about and I would be glad to be able to put them again to good use. Any assistance to this question would be greatly appreciated. Thanks!

    I think my motherboard is based on the Intel 915G Express chipset. It is a Dell Dimension 4700 desktop.
