    Hi, I saw that previous post about this topic were outdated (2015 solution). So i figured I’d start a new one for an updated solution.

    What im trying to achieve:

    I want SQ to use as much memory as possible that is available from my desktop. Currently I have set the memory usage to 128 gb of RAM. However through viewing from task manager, it is only showing 11% of RAM is being used. How can I increase the amount used.

    I tried to change the options in the configuration section (top right of SQ app). Here you can see the settings I put. I have tried the firs toption “determine maximum memory” but that resulted in low RAM usage.

    Thank you for your time!

    Hi,

    the memory is just not wasted when not needed. When it is not required for SQX it is not allocated. If you set a very large genetic population and use additional cross-checking and robustness testing more memory will be used.

    If you really want to utilize more RAM you can copy the entire SQX folder and run multiple copies of SQX. But benefits are questionable since you will also split your CPU resources

    the ram need to use sqx in the full cpu load was very decreased… i have also 128 GB ram from SQ3 times, where this amount ram was needed to run 40 cores in full load

    now with SQX even with my hardest workflow the sqx consumes something like 50GB max

    if you run already with 100% cpu load, you will get nothing more
