  • Hi vle87:

        I think your memory resources are normal.  Windows reserves various amounts of memory for many things but releases the memory on a priority basis as needed.  To see where your memory is reserved and being used,  open Task manager from the task bar, click on the performance tab,  then click resource monitor, then click the memory tab and you can view how your memory is being used.
       I have 4 GBs also and system information shows 4.00 GB  installed, 3.93 GB Total Physical,  1.88 Available Physical Memory, 7.86 Total Virtual Memory,  4.54 GB Available Virtual Memory and 3.93 GB Page File Space.  My video card has 512 MB onboard RAM.  You could type system info in the start menu search bar and see what yours reads to compare.  Different hardware on PCs can result in many different descriptions of memory availability.

  • Just a thought, is your ram same make and model as well as capacity and size? And is there any graphic card on the rig itself? If is using onboard graphic then some of the memory of the ram would be share. The other factor could be some of the ram or chip are bad.

    You could infact run memory diagnostic or memtest to ensure the problem is not lying with the ram

  • there's no onboard video, im using a geforce 8600gts with 256mb of memory, so it shouldnt account for the 1153mb which is reserved.
    all 4 dimms are same model. ill try to run a memory diag. but its kinda strange that the bios sees it fine, windows see its fine but it just allocates it somewhere else.

  • Be sure the firmware for your Bios supports the 4 gig
    I have an IBM T60 with 4 gig installed.
    Win 7 and Win2008 Server both report 3 gig useable 4 gig total (yes i do mean 64 bit versions of both)
    It took me a copple of days pokeing around before I actually spotted the small print on the Lenovo website that said the OS would address 3 gig !
