And don't believe anyone who tells you otherwise. Since Windows 7 was released last October I've read lots of articles about the right and wrong way to measure and manage the physical memory on your system. Much of it is well-meaning but just wrong. It doesn't help that the topic is filled with jargon and technical terminology that you literally need a CS degree to understand. Even worse, web searches turn up mountains of misinformation, some of it on Microsoft's own web sites.
And then there's the fact that Windows memory management has evolved, radically, over the past decade. Someone who became an expert on measuring memory usage using Windows might have been able to muddle through with Windows XP, but he would be completely flummoxed by the changes that began in Windows Vista and its counterpart, Windows Server and have continued in Windows 7 and its counterpart, Windows Server R2.
The behavior in all cases is strikingly similar and consistent, although you can get a misleading picture depending on which of three built-in performance monitoring tools you use. What helped me understand exactly what was going on with Windows 7 and RAM was to arrange all three of these tools side by side and then begin watching how each one responded as I increased and decreased the workload on the system.
To see all three memory-monitoring tools at work, be sure to step through the screen shot gallery I created here: How to measure Windows 7 memory usage. For someone who learned how to read memory usage in Windows XP, the Performance tab will be familiar, but the data is presented very differently. The most important values to look at are under the Physical Memory heading, where Total tells you how much physical memory is installed minus any memory in use by the BIOS or devices and Available tells you how much memory you can immediately use for a new process.
Performance Monitor This is the old-school Windows geek's favorite tool. One big advantage it has over the others is that you can save To run it, click start, type perfmon , and press Enter. To use it, you must create a custom layout by adding "counters" that track resource usage over time. The latter is the same as the Available figure in Task Manager. I'll discuss Committed Bytes in more detail later.
Resource Monitor The easy way to open this tool is by clicking the button at the bottom of the Performance tab in Task Manager. Resource Manager was introduced in Windows Vista, but it has been completely overhauled for Windows 7 and displays an impressive amount of data, drawn from the exact same counters as Perfmon without requiring you to customize anything.
The Memory tab shows how your memory is being used, with detailed information for each process and a colorful Physical Memory bar graph to show exactly what's happening with your memory. I believe this is by far the best tool for understanding at a glance where your memory is being used. You can go through the entire gallery to see exactly how each tool works. If you have more RAM than that, the basic principles will be the same, but you'll probably see more Available memory under normal usage scenarios.
As you'll see in the gallery, I went from an idle system to one running a dozen or so processes, then added in some intensive file operations, a software installation, and some brand-new processes before shutting everything down and going back to an idle system. At one point I had 13 browser tabs open, including one playing a long Flash video clip ; at the same time I had opened a page PDF file in Acrobat Reader and a page graphically intense document in Word , plus Outlook downloading mail from my Exchange account, a few open Explorer windows, and a handful of background utilities running.
And, of course, three memory monitoring tools. So why do people get confused over memory usage? One of the biggest sources of confusion, in my experience, is the whole concept of virtual memory compared to physical memory. Windows organizes memory, physical and virtual, into pages. Cacheman for Vista 7. MaxMem 1. CacheBooster 1. FreeMem Pro 5. CacheBoost Pro 5. RightMark Memory Analyzer 3. MemScope 1. MemScope presents an alternative algorithm to identify memory problems.
GoldMemory 6. MemTurbo 4. MemMonster 4. Using easy to use interface you quickly and safely monitor and increase the amount of available physical memory. Fast Defrag Standard 2. It features with a powerful engine and uses low system resources. Freeware application to free and optimize your computer's RAM Random Access Memory , resulting in an increase in system performance and productivity.
RAM Idle Le 1. RAM Idle LE is a smart memory management program that will keep your computer running more efficiently, faster, and longer. The program's intelligently manages the free RAM that is available to Windows. The RAMTester tool that is meant for checking memory modules reliability under MS Windows x86 and x64 on the example of virtual addresses. The idea of this utility is writing bit patterns into memory and then reading and comparing them with reference.
Ram2Free 1. Ram2Free does not run in the taskbar and use system resources when not in use. MemDefrag rev. With MemDefrag, you will optimize your RAM memory to reach the top of its usage, defragmenting the RAM memory in realtime and permiting that the programs use all of the memory on disposal in your computer.
RAM Def 2. Memory monitoring and cleanup tool. MemoryBoost Pro 2. MemoryBoost is designed to tackle the difficult but crucial problem of memory management. Memory is the most precious resource in your computer; when it becomes low, your computer will slow down severely or crash. AOK Ramfreer 1. RAMfreer is a smart memory management tool. It works by freeing up Physical RAM wasted by applications.
WinRamTurbo Free 2. WinRamTurbo increases system performance by making more RAM available for your applications and the operating system.
RAMBoss 1. MemWatcher 4. MemWatcher automatically frees up memory no longer in use by Windows, allowing programs to start faster and run smoother. Memory Optimizer Pro is the most advanced memory manager available, and it can proactively monitor your system memory and resources, freeing up RAM and preventing crashes.
Free Memory 7. MemStat XP 1. MemStat XP is utility that monitors physical memory in Windows systems. With this little tool you can track usage of memory in your system and easily free it if needed. Simply having a large amount of RAM does not mean your computer can use it. RAMpage 1. RAMpage is a small Windows utility that displays the amount of available memory in an icon in the System Tray. It can also free memory; by double clicking the tray icon, or by setting a threshold that activates the program automatically.
RAM Boost 2. RAM Boost is a little useful utility which forces Windows to move unused memory data into the swap file. MPower 1. Cleans and defrags RAM. Memory-Trax 3. By reclaiming your memory, you will find that your system crashes less and most other programs will run more smoothly.
MemoryElevator 2. If you want to perform any task under Disk Management in Windows 7, you must know how to access it. Here are 3 common methods to access Disk Management tool in Windows 7.
This method is usually easy to handle, so most Windows 7 users would like to access Disk Management with this method.
Based on its name, it is easy to understand that you can format partition, delete partition, change drive letter and paths, extend partition and shrink partition after accessing Disk Management in Win 7. Based on those basic features, you can resolve some related problem occurred on Windows 7.
Here are some related possible issues that you can resolve with Windows 7 Disk Management: 1. Create a new partition with Disk Management in Windows 7. During the usage of your computer, you may want to create a new partition sometimes.
On Windows 7, you do not need to repartition hard drive in order to create a new partition. You just need to follow the guide below to create new partition on Windows Enter the amount of space you want to shrink and then click 'Shrink' button so that you can get some unallocated space.
Follow the wizard to format the unallocated space and assign a drive letter to this volume, after which you can create a new partition. Another feature is that you can fix low disk space problem on Windows 7 with Disk Management.
