Hello,
> I have a 16gb mem system which can't be upgraded any further to my knwoledge. What is the reason? CPU limits? MoBo limits? Soldered RAM? If the reason is just MoBo limit, you can just try to ignore it? My old laptop was officially able to have at most 8GiB RAM because of MoBo limits. I was told to ignore it and try 16GiB, as the memory controller is in the CPU, which can handle such amount of the memory. And it works well. Also, my current laptop supports reportedly at most 16GiB. It currently has one 16GiB module plus one unused memory slot. I believe it will work fine with 16GiB+16GiB, as the CPU supports it. AFAIR, even some forum thread indicates this for this or some similar model. For Intel CPUs, the memory limit can be found at https://ark.intel.com/ . >I do not remember setting up a swap space during setup but I think it was set >up automatically though in the dom0 system monitor plugin the swap space >monitor never seems to move (stays at zero). Note that Qubes has a separate swap for each VM. You can see details using cat /proc/swaps, htop or gnome-system-monitor, whichever you prefer. But any of them will show you the swap status just for the one VM you run it in. Default swap setup: * dom0 - not sure * PV appVMs - 1 GiB swap (this limit used to be hardcoded, not sure about the current status). Theoretically, you can add an extra swap, but I don't think it makes much sense. * HVMs - depends on the guest OS Also note that swap does not work well with memory balancing, because Qubes counts used swap as used memory. As a result, even if the VM has swapped some memory, it does not offer it to other VMs. There was some discussion about it in the past. As far as I know, the only workaround on this fact is reducing the upper memory limit or even disabling memory balancing for the VM. > Are there any recommended ways for reducing memory usage? Note that VMs with some PCI device (most notably sys-net and sys-usb on clean install) have memory balancing disabled. It might be worth trying to reduce its memory to as low as 200MiB. > If swap is not being used how can I enable it? It depends on for what VM you want swap. When adding a swap for dom0, you might want the swap to be encrypted, ideally with a random key.
