A question about a RAM upgrade

Discussion in 'Computer Support' started by news.alltel.net, Jan 7, 2009.

  1. I recently doubled the RAM on my Vista-32 system. It had 2gb and I installed
    an extra 2gb, (two 1gb DDR2 modules). When I boot my computer and look in
    system information it tells me I have 4.0 physical memory but 3.0 available.
    At first I thought it was because Vista was using 1GB but then I look at
    performance tab in task manager and it tells me I have 3068 total physical
    memory. Does this sound like one of my ram modules is bad? Another reason I
    ask this is because my ram speed before the upgrade in my bios was 800mhz
    and now the bios says it's 667mhz even though on both boxes it says 800mhz.

  3. True or false, you chose.


    2x800 < 4x667

    As far as the 667Mhz down from 800, perhaps you can adjust it in the BIOS.
    Otherwise the new ram is probably actually slower, regardless of what it
    says on the packaging. The computer will run the ram at the speed of the
    slowest ram.
    You could, however, remove the old stick and just use the new stick and see
    if it still stays at 667Mhz.
    As the other poster says, 32bit will only recognize 3GB of ram and I believe
    that is true, but I am not positive.

    1024x3=3072 1 megabyte does *not* equal 1,000,000 bytes.


    So that leaves 4 megabytes unaccounted for.

    From the Wikipedia discussing hard drive size.

    Most operating-system tools report capacity using the same abbreviations but
    actually use binary prefixes. For instance, the prefix mega-, which normally
    means 106 (1,000,000), in the context of data storage can mean 220
    (1,048,576), which is nearly 5% more. Similar usage has been applied to
    prefixes of greater magnitude. This results in a discrepancy between the
    disk manufacturer's stated capacity and the apparent capacity of the drive
    when examined through most operating-system tools. The difference becomes
    even more noticeable for a gigabyte (7%), and again for a terabyte (9%). For
    a petabyte there is a 11% difference between the SI (10005) and binary
    (10245) definitions. For example, Microsoft Windows reports disk capacity
    both in decimal-based units to 12 or more significant digits and with
    binary-based units to three significant digits. Thus a disk specified by a
    disk manufacturer as a 30 GB disk might have its capacity reported by
    Windows 2000 both as "30,065,098,568 bytes" and "28.0 GB". The disk
    manufacturer used the SI definition of "giga", 109 to arrive at 30 GB;
    however, because Microsoft Windows, Mac OS and some Linux distributions use
    "gigabyte" for 1,073,741,824 bytes (230 bytes), the operating system reports
    capacity of the disk drive as (only) 28.0 GB.

    I think that 4 megabytes of ram is the stick of ram you're using in your

    No. This is something much less needed and far less rare.
