![]() Windows is constantly making these decisions managing a cache for hundreds of files that are constantly being written by background services whilst balancing it with the memory demands of active processes. giving RAM to the process that more actively needs it. The vast majority of the time Update is dormant while your desktop isn't, so it will page Update in favor of caching the desktop in active memory, i.e. Take Windows Update vs your desktop, for example. Windows will monitor memory usage and might page away processes with less activity to accommodate more active processes and also any processes that you may launch in the future. Windows will use the page file even when RAM is available: This is important to keep in mind, especially if you're seeing unexpected slowdown with large page files. According to Microsoft, kernel dumps will typically be around 1/3 the size of the RAM on your system. Kernel dumps are less demanding, but their size can vary considerably. Though complete memory dumps aren't typically needed since we also have kernel dumps, which will trim the file down by omitting information that is (probably) irrelevant to the crash. if you have 32GB of RAM but often work with 50GB data sets, then you'll probably want a page file somewhere in the ballpark of 32GB to cover the difference and accommodate anything else that might be allocating memory.īudgeting for Windows crash dumps: For complete memory dumps, you need a page file the size of your RAM + 1MB. The accepted answer here is what one would recommend to a casual user, not a power user.īudgeting for max workloads: If you expect to max out your RAM usage, then at the very least you should be budgeting enough virtual memory to cover any worst case scenarios. There is no hard and fast rule that encompasses the ideal page file size on all systems it's very specific to the workload your computer is exposed to. In most cases though using 1.5 times virtual memory for the amount of total RAM on Windows 10 systems will suffice and keep it simple or be a good enough starting point if simply allowing Windows 10 to manage it automatically will not work. ![]() While all this is really just a trivial matter, it'll add some complexity and time to get the most optimal configuration where this setting must be the most optimal. There are many options available to record and measure system performance metrics to help benchmark and super fine-tune this configuration if needed though. In these cases, depending on various factors of the system and what's important for the system processes, there are many other factors to consider obviously. It's probably true there is no ' one size fits all' formula for Windows 10 systems that are super fine-tuned to find the most optimal configuration per those systems. The maximum size of the swap file will be 1024 x 4 x 1.5 Mb. So it sounds as if the 12 GB configured in your system currently is correct so when or if Windows needs to utilize the virtual memory, the 12 GB should suffice.Īs a general rule, the maximum size of the paging file must be x1.5 To calculate the "general rule" recommended size of virtual memory in Windows 10 per the 8 GB your system has, here's the equation 1024 x 8 x 1.5 = 12288 MB. Minimum Pagefile size can be 1.5 GB, and the maximum size of the file For example, if your computer has 1 GB of RAM, the The minimum and maximum size of the Pagefile can be up to 1.5 timesĪnd 4 times of the physical memory that your computer has Typically you'll simply allow the Windows OS to dynamically manage this since in most cases that'll suffice and it'll work just fine. Windows 10 automatically manages the pagefile for your computer's configuration and the amount of RAM present in it.
