  • Error allocating RAM

    I have had this error occur on several different platforms.
    One is an Ipox mobile mini-ITX ADE-6051 with a core 2 duo T7100, the other is a MSI mobile 945GM2 with a core 2 duo T7200. Using version 5.3 1012. OS is XP SP2. The failure can take anywhere from 1 hour to 1 day to occur.

    Here's the end of one test log where the error occurs in about an hour and a half. Thanks.

    An "Error allocating RAM" error occurs when BurnInTest is unable to allocate a large enough block of sequential RAM for the RAM test. It is most typically caused by virtual memory fragmentation. It is highly unlikely to be a RAM hardware error.

    As it takes quite some time to occur, it would appear that some software (.exe, .dll) is allocating virtual RAM that is not being released from the virtual RAM address space. If this occurs then the free blocks with-in the virtual address space become smaller and smaller, to the point where it is smaller than the RAM test requires, and BurnInTest raises an error to basically indicate that it can't continue the test.

    We have done some testing with BurnInTest to try to confirm that it is not BurnInTest that is causing the memory fragmentation. At this stage it would appear not to be caused by BurnInTest, but rather more likely system software such as a library (system dll).

    Could you email me:
    - The full log file, and
    - Your configuration file (*.bitcfg)
    - The paging file settings (sizes)

    Either directly to me (you have my email address), or to help [at] passmark [dot] com

      Hello Ian,

      I've emailed you the info you requested. I gave you one erroneous piece of information - on the MSI motherboard, the OS was Win2K SP4. Thanks.
