Maximum possible array/out of memory 64bit Matlab+Windows 8 pro

Hi,

I am running Matlab 64bit on Windows 8 pro. I have 8gb of RAM installed on my laptop. When I enter memory I get the following:

Maximum possible array: 2237 MB (2.346e+09 bytes) *

Memory available for all arrays: 2237 MB (2.346e+09 bytes) *

Memory used by MATLAB: 574 MB (6.023e+08 bytes)

Physical Memory (RAM): 8077 MB (8.469e+09 bytes)

• Limited by System Memory (physical + swap file) available.

I would like to allocate much more than the 2237 MB to my arrays and I do not understand why Matlab is not using more. I read some help pages in the Documentation Center and as far as I understood with a 64bit OS, 64 bit Matlab should be able to create larger arrays than that.

Does this have something to do with Windows? I would appreciate any help on this because I ran into this problem before and I thought buying this new laptop to switch to full 64bit with more physical RAM would fix some of these limitations.

Thanks in advance!

Should be possible. I have a similar system, except it's only Windows 7

    >> memory
    Maximum possible array:              12248 MB (1.284e+10 bytes) *
    Memory available for all arrays:     12248 MB (1.284e+10 bytes) *
    Memory used by MATLAB:                1094 MB (1.147e+09 bytes)
    Physical Memory (RAM):                8073 MB (8.465e+09 bytes)

    *  Limited by System Memory (physical + swap file) available.

Does this just happen to be this way or did you change anything in order to allocate this amount? I guess you increased to swap file also to get more than your physical RAM? I do not even get my physical RAM as maximum possible array size.

I didn't tweak anything. This was result of a factory default install.
