HEY

If i should change my PSU from a 300 wat to either a 700 or a 800 wat to handle a GTX 260 or a HD 5780 card?My specs are AMD QUAD CORE 9500 2.2GHZ,3GIGS and Geforce 8500GT 256mb

  1. Well, there is no such card called the 5780. Maybe you mean the 5870? But anyway, a 500watt power supply would be more than enough to handle a HD5870 or a GTX260. You should get a 700 or 800 watt PSU if you plan to SLI or crossfire those cards, otherwise, there is no need.
  2. Ok thanx for the advise,and the correction
  3. Hey u think if i should upgrade from 3gigs to at least 5gig DDR2 run these up coming games ?

    Not for at least another year or two. You're CPU will start holding you back before ram starts to become an issue.

    Which OS are you running? 3 is a funny number when it comes to DDR2, so I'm pretty sure your RAM is not currently operating at optimum bandwidth capacity.
  6. i'm running windows 7 32bit

    In that case you won't be able to install more than 4GB of RAM.
  8. why?The maximum of my pc is 8GB of RAM.

    Its because you've a 32 bit operating system which can address upto 3.5GB of the memory at the max.. Btw, for your initial query, a 500W PSU will be enough though make sure it comes of a quality brand..
  10. so it all depends on my PSU?
  11. No...An operating system must address hardware. A 32bit operating system has only so much addresses for ram. If you have a 32bit windows 7, then it cannot recognize any more then 3.5-4GB of ram. So even if you put 10GB of ram...the system will only make use of 4. If you get a 64bit operating system...its a different story. A 64bit operating system has potential of utilizing hundreds of GB of ram...its usually limited in use to the specific OS but it has the "Potential of use more". Now before you think you can install win7 64bit, make sure your CPU supports it, if it doesn't then you can't install it.
  12. My CPU can run up to x86 cause it's a QUAD CORE processor.
  13. If i'm correct then i must change to x64bit or x86 to my RAMS use?
  14. x86 is an architecture...a single or dual core can also be a x86....

    Yes, you are correct, you must change your CPU to a 64bit CPU if it already isn't AND install a 64bit OS to make use of more then 3.5GB of ram.
  15. Okay,I'll take down a 64bit win 7 rite now!

    All CPUs that you can purchase as a consumer today are x86. It is an architecture and has nothing to do with memory addressing.

    There is no such thing as x64, therefore. You are confusing an extension of the x86 architecture with the actual base architecture of modern consumer CPUs.

    Anyway, you need not worry about your CPU. It supports 64-bit instructions. Your problem is your operating system, it does not. You need the 64-bit version of your operating system in order for your system to detect more than 4GB of memory (2 to the power of 32).
  17. Hey,when i install the 64bit version of the OS will i be able to get the full use out of my 3gigs or i should install at lease 4-5gigs memory?
  18. Well, okay thanx for the info.

    As I stated before, DDR2 does not work well in uneven numbers. Your motherboard normally has 4 RAM slots (2 if it's a smaller board), numbered 0-3. 0 and 2 work as a channel, and 1 and 3 work as a channel. DDR2 can operate in dual channel mode which effectively doubles your memory bandwidth, provided you install it in the correct slots, and the modules are of equal specification.

    My recommendation would be:

    a) 2GB modules in the 1st and 3rd slots if you want 4gB.
    b) 2GB modules in each slot if you want 8GB.

    That will ensure that your RAM works at peak efficiency.

    Legally, I hope?
