![]() ![]() The Intel P4 CPU could always address more than 4Gb (by using something called Physical Address Extension, or PAE) Old motherboard only supported 4Gb of physical RAM, modern ones support a lot more. Read also Microsoft KB 929605 - The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed. There were countless forum posts online related to this same topic. I ran in to this same problem a few years ago when I built a 4 GBs 32-bit Windows Vista system when Vista was first released. Speaking from personal experience, this is no new problem. However, you may be able to take advantage of the full 8 GBs installed if you followed these instructions. There is more information if you check out the source. Intel chipset specs are pretty good at explaining what address ranges gets reserved by default and in some cases call out that 1.5GB is always reserved and thus inaccessible to Windows. What this means is a typical system may see between ~256MB and 1GB of address space below 4GB reserved for hardware use that the OS cannot access. PCI Express support will reserve at least 256MB, up to 768MB depending on graphics card installed memory.BIOS – including ACPI and legacy video support.Significant chunks of address space below 4GB (the highest address accessible via 32-bit) get reserved for use by system hardware: This is independent of the OS running on the machine. Those reservations overlay the physical address space and mask out those physical addresses so that they cannot be used for working memory. This behavior is due to "memory mapped IO reservations". However, I did find a more detail reason why your system shows less available ram than what is actually installed.įrom The 3GB-not-4GB RAM problem (Microsoft MSDN blog):ĭue to an architectural decision made long ago, if you have 4GB of physical RAM installed, Windows is only able to report a portion of the physical 4GB of RAM (ranges from ~2.75GB to 3.5GB depending on the devices installed, motherboard's chipset & BIOS). You will never see over 4 GBs if you are using a 32-bit Windows XP. ![]() Instead, it applies to 32bit desktop Windows - 32bit Linux systems with PAE and many 32bit Windows Server editions support more than 4GB per the linked article. Does anybody know some way to shrink the amount of opened files? Great desktop environment by the way, I like it.First, Windows XP (32bit) only supports 4 GBs. I guess this might be too much for Cinnamon. Things were worse when I launched some apps in firejail, as I remember (now I don't do that, maybe that helps). Maybe the startup applications overload my Cinnamon too, these are the following, besides the standard, built-in ones (startup applications won't launch, so its from my memory): I'm currently using the not so elegant solution: I launch programs with Synapse without launch icons.
