    tweak Win 7 for more RAM?

    I read a few articles that states that M$ set certain versions of windows to only recognize certain limits of RAM:

    Here are the upper RAM limits for the different editions of Windows 7:

    Starter : 2GB
    Home Basic : 8GB
    Home Premium : 16GB
    Professionall: 192GB
    Enterprise : 192GB
    Ultimate : 192GB

    Question is, can I tweak Win 7 64bit Home Premium to recognize the 32GB I want to put in or am I stuck at 16GB?

    I'd rather not have to buy a new version of Windows 7 since Win 8 will be out soon.

    on top of that, per M$'s site:

    http://windows.microsoft.com/en-US/w...oducts/compare

    There doesn't seem to be anything that I'd want from Professional or Ultimate......

    Why do you think you need more memory?

    If the system isn't paging, you aren't using the memory you have. Use perfmon.exe to look at memory page reads per second and memory page writes per second. A certain amount of paging is built into the program code for startup, shutdown and error routines. Unless the counters are consistently greater than 5 page I/O's per second, additional memory won't improve performance. Neither my 4 GB dual core notebook nor my very busy 16 GB 8 core server consistently page at all.

    also per another thread:

    well I may run sonar 8 and adobe production at the same time
    and latency is a very big issue so RAM would be the answer

    Memory cache faults per second is an indicator of file system activity. It is not very relevant for random disk file I/O. The cache keeps recently read/written data available in case it needs to be read again. In which case a file I/O operation is not required to retrieve the data. The cache fault value of less than 1 per second is unremarkable considering that physical disk I/O's per second (IOPS) are measured in the hundreds for SATA drives and the thousands for SSD's.

    Adding additional memory will not necessarily be used for cache.
    The easiest way to increase the file system memory cache is to use fsutil to set MemoryUsage to 2. The default is 1 and "not set" is 0. The other way to change the value is to edit the registry.

    To see the current value open a CMD window and enter fsutil behavior query memoryusage.

    Here is the performance tool I use. It is much better than the Task Manager tool.

    Run perfmon.exe
    Click performance Monitor
    Click the green + to add counters
    Click Memory from the list in the upper left panel to expand the selection
    Add Page Reads/sec
    Add Page Writes/sec
    Add any other counters you wish such as Cache
    Click OK
    A line graph window will display
    The graph can be changed to a histogram or a report.
    Keep in mind that some paging operations are hard coded into the programs and will occur no matter how much memory is available.

    For clarity Highlight the default %Processor counter and click the red X.
    The remaining graph will show disk reads and writes due to hard memory faults.
    Soft memory faults don't count because all that means is that the data is located in the memory cache and physical page file I/O is not required.
    Here is a sample report and a matching line graph. I've added Page file use as well.

    I do not think that it can be done.

    Life has its own balance I assume that any one that do a level of professional work that 32 GB will serve him better than 16GB, it worth is while to upgrade from Home to Pro for $79.

    It is kind like if you get an invitation to race in the Indi 500 you do not look to buy a used car for $500.
