Types of Memory for XPS 720

All I'm looking to move to Widows 7 from Window XP. I'm currently have 3 mb (PC-5300). I did a scan on Crucial website. Their recommend upgrade was PC-5300 DDR2-667. I noticed there were option for PC-6400 and PC-8500. Would those others work. If so, would I notice a difference?

  1. The Dell PC supports up to DDR2 800 (PC-6400), so you will be good to go with the PC-6400.

    I think you mean GB. :)
    The new memory would only run the lower stated speed if mixing modules (If the MOBO accepts it). You would notice no differnce unless you like running benchmarks.

    How many of which RAM modules have you got installed already? 4 slots in XPS 720?

    A few points.
    Firstly, you woud want the 64bit Windows 7 as 32bit can only use 3-3.5GB.
    Secondly, you only have four slots, so upgrades would have to replace current modules depending on the current set up.
    Thirdly, You may not notice much improvement unless you are performing memory intensive tasks.

    Hope that helps.
  3. I'm looking to upgrade the 4 slots with 2 mb for a total of 8 mb. I'm looking to move to Windows 7 64 bit.
  4. If your PC is a gaming PC, you will have little benefit with going 8GB of RAM. I would stick with just 4GB of memory.
  5. Fair enough.
  6. I use Access and manipulate data with a couple other programs for work, and I'm starting to get into video editing.
  7. For those applications, you will be more CPU limited with the dual core over the memory. They will benefit great by raw power of a quad core.
  8. I'm not ready to purchase a new PC and there are very few quad core processor that are still available for Socket 775.
  9. Excellent tips.Really useful stuff .Never had an idea about this.Keep it up

    Thanks
