    32 bit vs 64 bit performance with same RAM


    Hello,
    I have 2 questions that I need answers:

    1)If I have 3.00 Ghz processor, and 4GB of RAM, 32-bit or 64-bit will have a better performance? And if I upgrade my RAM to 8GB, will it boost performance of my 64-bit system a lot? What is the recommended RAM for 64-bit system for best performance if I don't play any games?

    2)My Windows Experience Index score is always low because of "gaming graphics" score which is 3.2 (lowest), anyway to boost the score to become high (more than 5.0) without changing my video card (I am still thinking to change or not)?

    Thank!

    1. With 64 bit. Windows alone will occupy around 3GB of RAM so that will leave 1GB available for anything else. Any application that you run will first be loaded into RAM then run. So the answer is 8GB would be ideal.
    2. I would not worry about the WEI if you are not playing any game

    1. A 64 bit OS was never about performance. Which OS will perform better depends on many factors but 64 bit systems tend to perform better if you have 4 GB or more RAM. Within reasonable limits adding more RAM will improve performance. But there will always be a point of diminishing returns beyond which there will be little improvement. That point and how much improvement there will be depends on what applications you are running and multiple other factors. But for general use that point is usually around 8 GB. More RAM will help but probably not much. There are always exceptions.

    Be aware that only a 64 bit OS can use more than 4 GB RAM.

    2. The only thing that will significantly improve gaming graphics is a new video card. But if you are not playing games why do you care? What are you doing that would benefit?

    I understand that there are tricks to change the WEI numbers but they don't improve performance. You would only be fooling yourself.

    Thank for reply.

    So I will upgrade RAM to 8GB RAM.

    But if I have 8GB RAM and a very bad video card, does it will effect PC performance, or not at all, only for games?

    Thank.

    Forget the video card if you don't play games. That WEI means nothing regarding the rest of your system performance.

    Btw - with 4GB of RAM, a 32bit OS is the better choice. But you want to upgrade the RAM. Then you need 64bit. But don't expect wonders in normal performance behavior. Only for few RAM intensive programs you will see a difference.

    I would put the money into a SSD. That gives you a much better performance deal for the money.

    Thank everyone for reply.

    But I still have question. Although I have only 4GB RAM and use 64-bit OS, my OS only use 20% of RAM when idle (task manager show) and I not allowed any program run at startup (except antivirus). It use 30-40% of RAM when doing work, and I try to open a 3D games then my RAM only used up about 60% (still have 40%).

    So in this situation does upgrade to 8GB will boost performance?

    The Task manager display is often misunderstood. That 60% usage doesn't account for full memory usage. In Resource Monitor look at the value for "Standby" memory. This is not unused but makes a considerable contribution to good performance. Only memory that is labeled as "Free" is unused. With 8 GB memory Standby will be larger and performance better.

    Even some computer professionals have been confused by this.

    Thank you very much for reply. I will decide to upgrade to a new 8GB RAM with faster speed.
