    In my bios under system info it says
    memory: 3200MB
    appropriated: 896MB

    Not sure why it does that.. At first I didn't care as I primarily run XP32, so it only uses 3GB anyways.

    But I installed Windows7 x64 to play with it, and it shows the same as my bios, 3200MB total.

    Now 896MB happens to be the memory my gpu has (gtx 280) so I wonder if it's doing something weird like holding it for it?

    Anyways, anyone know whats going on, is it normal or no?

    System specs per my panel..

    I have to enable the "memory hole" in my bios to use the full 4 gig.

    no idea about the bios option but afaik there are no gtx 280 cards with only 896 MB of memory. so where did you get yours?

    Nothing you can do you can do a work around to SEE 4GB but you can't actually use 4GB in 32bit vista/xp was the same as me i had 3254MB ram but im 64bit now so i can use all my ram :)

    W7 x64 can use 4 gb, it supports up to 128 GB of internal memory if MS didn't change that number, just like XP x64 and Vista x64.

    You need to enable memory remapping in BIOS.

    interesting note: according to what I know Vista 64 bit has different memory maximums depending on what version you have..

    64bit basic has a max of 8 gig.. dont know what the others are.. I do know the max is 128gig... on the most expensive editions.

    kinda wierd if you ask me... and here I have basic cause I thought it would just have less extra crap I dont want/need for a pure gaming rig.... oh well.

    I know home Premium supports 16GB (the max most Mobos can support)...

    If its a 64bit OS, either some of the RAM is bad, theres a BIOS option keeping RAM from being used, or M$ *forgot* to properly code their new os...

    Yep that was it, thanks Anarion.

    My bios says this option provides better compatibility for 32bit OS when off, so it's default to off. Turned it on brought it up to 4gb.

    dear all
    i hv the same prob as like in this thread.
    but
    myself having 4gb in my board. but my sys couldnt run til 4gb which is only run as in 2.5gb. this is abnormal whereby other user who install OS in 32bit detects 3.25GB for their ram usage in the OS.

    How would i need to do in order to get 3.25gb o more bcos 2.5gb is alrdy running abnormally.

    every kind of testing for hardware is done. so, pls recommend some other solution like i hv read memory mapping would work. but for gigabyte ep45-ud3l i duno where to do that in bios.

    or hv some other way to solve it. pls advise. :bang:

    thank you.

    ^What he said.


    ^What he said


    Actually that's bang on. 3200 + 896 = 4096Mb

    Your BIOS is seeing the whole 4 gig but some of it is reserved for onboard devices and gfx cards etc, which is normal, so looks like remapping is already enabled....

    If remapping is enabled in the bios then your motherboard doesn't support 4Gb RAM. Some chipsets don't. There was a member here, Sava99 I think, who had the same problem as you. Might have even been the same board.

    If your board doesn't see all your ram then your OS definitely won't.

    If you have integrated graphics make sure it's disabled if you don't use it, or the bios will assign system ram to it for the frame buffer.

    my bios can detect 4gb. but not in my OS (vista 32bit). i wonder y only my board detects 2.5gb way too low for detection. isnt it. surely something o some setting is wrong.

    how to check the remapping in my board model?

    Sorry I thought you were using XP.

    The available physical memory shown in the Vista Task Manager is what is left over for the system after memory has been allocated to onboard devices. (That's what I have read)

    Your OS can see a max of 3.5 Gb physical memory. around a gig of that is assigned to your video card, so you should have 2.5Gb left over - which is what is displayed in your task manager.

    But you maybe able to increase the amount of ram the bios lets vista have by enabling remapping. There should be an option in your bios under the memory options that looks like "memory remapping" or "memory hole". If it's in there just enable it.
    I'm not familiar with your board though. I just realized what I said i my last post. If there is a memory remapping option available then yeah of course your board would support 4gb...

    You should set the amount of shared memory for your gfx card to a smaller amount if you want more system RAM. I would. You may have an option in your bios to change the size of shared video memory/frame buffer.

    yes, thus is it true or real that my 2.5gb n suppose to hv 1gb extra if not assigned to GC huh.

    then would it able to take out frm the GC setting rather than go for remapping. cos, gigabyte dont hv such term, remapping or memory hole. can u pls help ask around ur area who using gigabtye?

    does asus got such term or keyword??
