Upgrade dell xps 7100

Currently have Dell XPS 7100 studio phenomllx6 1075t 3.0ghz - 8gb, amd radeon 6700 series. I believe CPU is 460 watt. Doing more rendering and wondering what nvidia would fit in dell xps 7100. AMD Radeon 7870 was suggested and would like to compare with nvidia. Hope this is sufficient info and thanks in advance for advise.

  1. Hi

    Do you have your motherboard model?
  2. Dell ONWWYO AOO. couldn't see anything on the board itself so this is a belarc advisor

  3. Let me provide all information I know about upgrading your XPS, so you can choose the most appropriate to your needs.
    About processor. Since you already have Phenom II X6 1075T the list will include only X6 CPUs, note that this is Dell approved ones

    Here are the Processor Kits that Dell associates with the Studio XPS 7100 system:

    * 1NDY0 AMD Phenom II X6 1035T
    * M7P5K AMD Phenom II X6 1045T
    * 68DKM AMD Phenom II X6 1055T
    * YF80X AMD Phenom II X6 1075T
    * 963RW AMD Phenom II X6 1090T

    So, only 1090T is above your choice, not worth it. However, 1075T is Black Edition (unlocked multipliers) or not? I think it is - and if it is so, you can overclock it in this particular Dell. So, some improvement here is possible.

    Memory. Memory can go up to 16GB, memory used is DDR3 1333 MHz, you can get improvement here.

    I found out that this 460 PSU can support up to 6970 card (no matter what it said on minimum requirements) http://en.community.dell.com/support-forums/desktop/f/3515/p/19395350/19924508.aspx#19924508

    If you decide to upgrade you power supply. Most generic standard ATX power supply units can be installed, with either a 24-pin or 20+4-pin main motherboard power and P-2 12V 4-pin connectors, with or without the on/off switch. I recommend a good name brand unit though.

    You should be able to buy a compatible power supply from either a local or online computer store.

    Note: A power supply with five SATA power connectors, is needed.

    Special note regarding size of ATX PSU. XPS 7100 chassis requires a standard-length (5.9-inch) ATX power supply. Some ATX power supplies, like the OCZ "Fatality" 550-watt, will not fit because they are too long and will overlie the two metal catches in the chassis, however, it is possible to remove the two catches with a grinder or other tool (I did it on my Inspiron 570, a little headache and no problems).

    Check the length first before buying an aftermarket power supply for the XPS 7100.

    Anything else, I missed?

    So, based on this information, you can easily choose any components you wish.

    If you are interested in overclocking, let me know, so we can discuss it here after you choose graphic card.
  4. Thank you for the information. Do you think an upgrade to the amd radeon 7870 would require a higher watt power supply? I am rendering in a cabinet design program which works fairly well and was told that maybe just upgrading the graphics card would make things faster.
  5. 7870 requires at least 500 watt and 6970 tested on 460 watt Dell PSU requires 550 watt, I know for fact that low power Dell 250 watt PSU is actually producing about 280' watt, so it is not a surprise to me that your 460 watt PSU is capable to support 550 watt cards, also take into the account that in reality it is not 550 watt requirement, but much less, card manufacturers usually overstate power requirements. So, you OK.
