I need some kind of graphics card

    just make sure your motherboard has an appropriate slot for you to be able to plug the graphics card in. pick a current-generation card that has at least 1 GB. people will try to convince you that you can get a last-gen card that's more powerful for a better value. don't get lured in. for your system, you want the latest decoding engines for video and the newest DirectX support for the best user interface experience. and see if you can grab something on sale. a few months ago, I grabbed a 6450 for my dad and it only cost $25 after rebate. things are always on sale.

    heck, at Newegg, I see the 6450 at $30 after rebate:
    Newegg.com - SAPPHIRE Radeon HD 6450 1GB 64-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card ( 100322L)

    Or, if you're willing to drastically change your system... you can get a motherboard/CPU combo that has Nvidia or ATI and that's dirt cheap and skip the graphics card (or throw on something cheap like the aforementioned 6450 which not only gives better performance but allows you to then have 4+ monitors plugged in together. Of course, it all depends on what your realistic budget limits are.

    It used to say 2gb nothing else.
    I am guessing that none of you had the heart to tell me, that although I have upgraded to 8 pro and added 2gb of ram making a total of 4gb that my ancient mobo is still limiting me to 3.?? of useable ram.

    Am I right.?

    An HD Radeon 6450 Can Run on a 350W Power Supply


    Hello all,

    I am running a Sapphire (no fan) HD Radeon 6450 on a 350W power supply without issue. However, I do not have an excessive drain on the power supply (using only 1 hard drive and other standard hardware). Moreover, from my observations, excessive heat does not appear to be a problem with this specific graphics' card. Also, my Dimension 8400 case only has 1 fan and the graphics card maintains an idle temp of 40c and a normal use temp of 41 to 42c (according to CPU-Z).

    It is a nice card but it is definitely not for gaming.

    Good luck!

    You need to be more specific than 3.??

    A response of 3.?? is too vague for a proper response; however, FYI, you will never have full use of that 4gbs of installed RAM because some is reserved by the system and allocated elsewhere. The best thing to do is show us a snapshot of your resource monitor at work. Here's mine, I have 3gbs installed:

    are you sure that you installed the 64-bit version of Windows 8 and not the 32-bit? it's not your motherboard limiting your RAM per se. it's 32-bit limiting your RAM.

    The main reason you go with 64-bit Windows is that you can install more physical memory. 32-bit versions of desktop Windows are limited to 4GB of physical memory, and thanks to dubious compatibility restrictions, they can't even offer that much. Every byte of memory in a system has a physical address, a number representing that byte of memory, and on 32-bit desktop Windows, those addresses are only 32 bits long (or rather, the addresses are between 36 and 64 bits long depending on which bit of software is manipulating them, but only 32 bits are actually used by Windows). This should allow 232 addresses, and hence 232 bytes—4GiB—of memory.

    But unfortunately, physical memory isn't the only thing using that address range. Peripherals such as video cards also carve out chunks of the address range, so that the CPU can communicate directly with them. Video cards in particular will often attempt to place all of their video memory—hundreds of megabytes, sometimes even gigabytes—within this range. When this happens, the physical memory loses out, and has to be relocated; it is given addresses that require the use of the full 64 bits. Since Windows only uses 32-bit physical addresses, that means that you lose access to some of your RAM.

    In other words, with a 32-bit operating system, all the RAM of all your devices have to fit within this 4GB address space. So if you install 4 GB of system RAM and then you plug in a 1 GB graphics card, that means your system will only recognize 3 GB of system RAM because you have 4 GB total in a 32-bit address space. If you plug in a 2GB graphics card, your system will have 2 GB of RAM even though you have 4 GB plugged into the motherboard.

    With a 64-bit operating system, the limit is much much much higher than 4 GB and basically becomes "limitless" for a typical consumer.


    Now, that's for your hardware side... The benefit for 64-bit on the software side is this... On 32-bit Windows, in normal configurations, each program only has a usable address space of about 2GB, half of the total memory that can be addressed with 32-bit addresses. This means that the amount of RAM that the program can manipulate directly is limited to 2GB. If the program needs to work on a larger chunk of data, it has to move that data in and out of RAM a piece at a time, usually storing it on disk when it's not in RAM. This 2GB limit is regardless of the amount of physical memory installed; if you run multiple programs, they each get a 2GB block of their own, so they can use many gigabytes in total, but any individual program can't readily break through this limit.

    So that means at any given time, a program (in a 32-bit) operating system can only have access to 2GB for itself no matter if your system has 16GB or whatever amount of RAM.


    Not so with 64-bit programs; 64-bit programs get 64-bit addresses, giving an address space of more than 18 billion gigabytes, of which they can theoretically use half. This limit is "theoretical" because neither current 64-bit x86 processors nor Windows support quite that much. The actual limit in theory is a mere 8TB, but this is still 4096 times more than 32-bit programs can use.

    I fitted a Geforce GT 610 this morning, so down to 2.95 usable.

    It looks like you have too much memory (1089mb) marked as "Hardware Reserved" and that is why your useable memory is lower than expected. Now, finding out why is a whole new ballgame. This could be caused by a memory mapping problem or an option setting in your BIOS; however, since I am not an expert in this area, you would be better served if someone else continues to help you from here.

    For a good, non-gaming PC, I strongly recommend the nVidia GT-430, which is an older card PCIe 2 card that you can probably pick up new for $50. It runs Win7 and Win8 very well and it had VGA and DVI on it.
