Quick note: The memory dump files contain everything available in memory and are usually as large as the memory size. In contrast, the minidump files are only several megabytes in size, and they. Best way is firstly use finish and after that use System.exit (0) to clear static variables. It will give you some free space. A lot of applications leave working processes and variables what makes me angry. After 30 minutes of using memory is full and i have to run Task Manager - Lvl 2 clear memory.
Anyone who regularly works with a computer and has to deal with software which requires a lot of processing power knows how important powerful hardware is. Most people immediately think of the processor or graphics card (especially when the focus is on image and video editing). However, the main memory is also of fundamental importance for the smooth operation of the system and other software. This memory is required by the processor to manage the data of running programs and services or processes. The capacity of the main memory has a decisive influence on how many applications can be loaded simultaneously and how quickly data can be processed.
Since I very much want use the app again, I thought I would delete it and download it again. So, I have done the following: deleted the app off my phone, then added it again. Still hold the memory for the false log-in. Deleted the app off my phone AND iTunes (computer), then added it again on my phone. Still holds the memory.
In principle, the more memory, the better. However, since the costs also play a role and the RAM memory cannot be expanded, many people use a fairly simple trick when the memory reaches its limits - deleting processes that are no longer required from the cache, and creating space for the data that is relevant for your current activities. This increasing your RAM. So all you do is clear the RAM or free it up.
- Free up your RAM – here’s how
What is the function of the main memory?
The main memory, also called RAM memory, is the central storage unit for all data that is required for programs or program parts that are currently running and for all active system processes. This memory, whose data is automatically lost when the computer is switched off, is accessed directly by the processor. If there is not enough memory available to process the relevant data during such an access attempt, the execution of the respective application will not work. The more processes take place simultaneously and the higher the system requirements of the executed programs, the more important a high capacity RAM becomes.
Which factors are vital for an efficient RAM?
The performance of the main memory is affected by the following three factors:
- Access speed: time required for successful access (write or read operation)
- Data transfer rate: a value that indicates the amount of data that can be transferred in a given time
- Memory capacity: available RAM
These three things are essential for the efficiency of the main memory in managing processes to be executed. Capacity is of particular importance, as it sets a strict limit to the storage capacity. For example, if an application requires 2 gigabytes and another 3 gigabytes of memory over a longer time, both cannot run simultaneously if only 4 gigabytes of memory are available. However, when it comes to processing a large number of temporary processes, access speed and data transfer rate come into play. The faster the individual data is processed and then disappears from the main memory, the faster space is freed up from the RAM for new processes.
Why is it a good idea to clear your RAM? And when should you do this?
A slow PC can be frustrating, especially when you need to problem solve and use your computer quickly. An ever decreasing performance of the computer is often connected with straining the RAM. On the one hand, it is already automatically occupied by the operating system and system processes, on the other hand, it gets a bit fuller with every open program. Often it is of little use to close programs again. The latter is due to the fact that all files are rarely deleted from memory when you close an application. In addition, there are programs and processes that are active but not actually needed. For the above reasons, it may be advisable to clear the RAM if your computer shows signs of a significant decrease in performance
Free up your RAM – here’s how
Even if you are unsure whether your computer's memory is actually too full, you can try and free it up anyway. This way you’re only pre-empting an operation that would be performed automatically when you turn off your computer (but save the files you are working on so that your work results are not lost). In general, you have three different options for clearing your RAM manually:
- Empty the working memory via the task manager of your system
- Write a script that releases used memory
- Use an external tool that has a function for emptying RAM memory
The following sections explain what you need to do in detail.
To clear the RAM in Windows 7, 8, and 10 via the task manager
The task manager has long been an established feature in Windows systems. The background service lists running applications, services, and processes and also provides an overview of CPU and memory usage. Opening the Windows service works across all Windows versions by pressing the key combination[Ctrl] +[Shift] +[Esc]. Press these three buttons simultaneously to open the interface. Alternatively, you can also use the Windows search: Simply enter the term “Task Manager” and then click on “View running processes with Task Manager.”
To use the task manager to empty the working memory under Windows 7 and other versions select the “processes” tab:
Now go through the list of active processes and search for those that you do not need – for example, because you have already closed the program. Select the corresponding processes with a left or right click and press “end task” to close them permanently and clean up the working memory piece by piece.
Empty memory via script: the necessary steps
An interesting alternative to memory management via the task manager is to write a script that frees up a specified amount of RAM when it is executed. That sounds like a complex task at first glance – but you don't need any programming experience. A small entry in a simple text document created for this purpose is completely sufficient. To create a script to clear the RAM, proceed as follows:
Create a new text document by right-clicking on your desktop and selecting “new” and “text document” in the pop-up menu:
Open the created document and insert the following line of text:
Then save the file under the desired name. Make sure that ANSI is set as the encoding form if the editor offers an appropriate option. The last step is to replace the default extension .txt with the extension .vbs. Only in this way can Windows determine that the file is a script.
You can now execute the script simply by double-clicking it. The code proposed here automatically releases 32 megabytes of main memory, and this process can be repeated as often as required. Of course you can also adjust the amount and empty 128 megabytes (“Space(128000000)”). However, the value should never exceed half of the built-in memory size – otherwise there is a risk of program errors or even system crashes.
How to clear RAM with external tools
If you want to use an external solution instead of the system-internal possibilities for memory cleaning, this is also possible without problems: there are various programs that were developed especially for this purpose and are mostly freeware. One of the most popular tools of this kind is Wise Memory Optimiser. The program by the developer company WiseCleaner is completely free of charge and available for all current Windows systems. After you install and start Wise Memory Optimizer, you will be taken to the main screen of the application, which displays both the occupied and free memory. With a single click on “Optimize Now” you can use the tool to empty the memory under Windows XP up to 10.
Under the tab “settings” (the gear symbol), you can activate auto-optimization. Use the slider to specify how much should be cleared from the RAM automatically (for example, if less than 1280 MB is free, then the RAM should be optimized).
As an alternative to Wise Memory Optimizer, you can also use the tools RAMRush or Mz RAM Booster to clear your RAM.

Symptoms
After you upgrade to Microsoft Office 2013/2016/Office 365, you experience one or more of the following symptoms:
The computer uses more memory when you open multiple Microsoft Excel 2013 workbooks, save Excel workbooks, or make calculations in Excel workbooks.
You can no longer open as many Excel workbooks in the same instance as you could before you upgraded to Excel 2013/2016.
When you insert columns in an Excel workbook, you receive an error about available memory.
When you are working with an Excel spreadsheet, you receive the following error message:
Cause
Starting in Excel 2013, improvements were made that require more system resources than earlier versions required. This article identifies areas in Excel workbooks that use lots of memory and describes how you can make your workbook files work more efficiently.
For more information about the changes that we made in Excel 2013, see Memory Usage in the 32-bit edition of Excel 2013.
Resolution
To resolve this issue, use the following methods in the order in which they are presented. If the one of these methods does not help, move on to the next method.
Note
Many Excel workbooks have several issues that can problems. After you eliminate these issues, your workbook will run more smoothly.
Formatting considerations
Formatting can cause Excel workbooks to become so large that they do not work correctly. Frequently, Excel hangs or crashes because of formatting issues.
Method 1: Eliminate excessive formatting
Excessive formatting in an Excel workbook can cause the file to grow and can cause poor performance. Formatting would be considered excessive if you formatted whole columns or rows with color or borders. This problem also occurs when formatting requires data to be copied or imported from webpages or databases. To eliminate excess formatting, use the format cleaner add-in that is available in Clean excess cell formatting on a worksheet.
If you continue to experience issues after you eliminate excess formatting, move on to method 2.
Method 2: Remove unused styles
You can use styles to standardize the formats that you use throughout workbooks. When cells are copied from one workbook to another, their styles are also copied. Photoshop elements 8 serial number. These styles continue to make the file grow and may eventually cause the 'Too many different cell formats' error message in Excel when you save back to older file versions.
Many utilities are available that remove unused styles. As long as you are using an XML-based Excel workbook (that is, an .xlsx file or an. xlsm file), you can use the style cleaner tool. You can find this tool here.
If you continue to experience issues after you remove any unused styles, move on to method 3.
Method 3: Remove shapes
Adding lots of shapes in a spreadsheet also requires lots of memory. A shape is defined as any object that sits on the Excel grid. Some examples are as follows:
How To Clear Application Memory On Mac
- Charts
- Drawing shapes
- Comments
- Clip art
- SmartArt
- Pictures
- WordArt
Frequently, these objects are copied from webpages or other worksheets and are hidden or are sitting on one another. Frequently, the user is unaware that they are present.
To check for shapes, follow these steps:
How To Clear Memory Cache Win 10
- On the Home Ribbon, click Find and Select, and then click Selection Pane.
- Click The Shapes on this Sheet. Shapes are displayed in the list.
- Remove any unwanted shapes. (The eye icon indicates whether the shape is visible.)
- Repeat steps 1 through 3 for each worksheet.
If you continue to experience issues after you remove shapes, you should examine considerations that are not related to formatting.
Method 4: Remove conditional formatting
Conditional formatting can cause the file to grow. This occurs when the conditional formatting in the file is corrupted. You can remove the conditional formatting, as a test to see if the problem is with corruption in the formatting. To remove conditional formatting, follow these steps:
- Save a backup of the file.
- On the Home Ribbon, click Conditional Formatting.
- Clear rules from the whole worksheet.
- Follow steps 2 and 3 for each worksheet in the workbook.
- Save the workbook by using a different name.
- See if the problem is resolved.
If removing conditional formatting resolves the issue, you can open the original workbook, remove conditional formatting, and then reapply it.
Problem remains?
If none of these methods work, you may consider moving to a 64-bit version of Excel, breaking your problem workbook into different workbooks, or contacting Support for additional troubleshooting.
Calculation considerations
In addition to formatting, calculations can also cause crashing and hanging in Excel.
Method 1: Open the workbook in the latest version of Excel
Opening an Excel workbook for the first time in a new version of Excel may take a long time if the workbook contains lots of calculations. To open the workbook for the first time, Excel has to recalculate the workbook and verify the values in the workbook. For more information, see the following articles:
If the file continues to open slowly after Excel recalculates the file completely and you save the file, move on to method 2.
Method 2: Formulas
Look through your workbook and examine the kinds of formulas that you are using. Some formulas take lots of memory. These include the following array formulas:
- LOOKUP
- INDIRECT
- OFFSETS
- INDEX
- MATCH
It's fine to use them. However, be aware of the ranges that you are referencing.
Formulas that reference whole columns could cause poor performance in .xlsx files. The grid size grew from 65,536 rows to 1,048,576 rows and from 256 (IV) columns to 16,384 (XFD) columns. A popular way to create formulas, although not a best practice, was to reference whole columns. If you were referencing just one column in the old version, you were including only 65,536 cells. In the new version, you're referencing more than 1 million columns.
Assume that you have the following VLOOKUP:
In Excel 2003 and earlier versions, this VLOOKUP was referencing a whole row that included only 655,560 cells (10 columns x 65,536 rows). However, with the new, larger grid, the same formula references almost 10.5 million cells (10 columns x 1,048,576 rows = 10,485,760).
This is fixed in Office 2016/365 version 1708 16.0.8431.2079 and later. For information on how to update Office, please see Install Office updates.
For earlier versions of Office you may need to reconstruct your formulas to reference only those cells that are required for your formulas.
Note
Check your defined names to make sure that you don't have other formulas that reference whole columns or rows.
Note
This scenario will also occur if you use whole rows.
If you continue experience issues after you change your formulas to refer only to cells that are being used, move on to method 3.
Method 3: Calculating across workbooks
Limit the formulas that are doing the calculations across workbooks. This is important for two reasons:
- You are trying to open the file over the network.
- Excel is trying to calculate large amounts of data.
Instead of doing calculations across networks, contain the formula in one workbook, and then create a simple link from one workbook to another.
If you continue to experience the issue after you change your formulas to refer only to cells instead of calculating across workbooks, move on to method 4.
Method 4: Volatile functions
Limit the use of the volatile functions in a workbook. You do not have to have hundreds of cells that use the TODAY or NOW function. If you have to have the current date and time in your spreadsheet, use the function one time, and then reference the function through a defined name of a link.
If you continue to experience the issue after you limit your volatile formulas, move on to method 5.
Method 5: Array formulas
Array formulas are powerful. But they must be used correctly. It is important not to add more cells to your array than you must have. When a cell in your array has a formula that requires calculation, calculation occurs for all cells that are referenced in that formula.
For more information about how arrays work, please see Excel 2010 Performance: Tips for Optimizing Performance Obstructions.
If you continue to experience the issue after you update your array formulas, move on to method 6.
Method 6: Defined names
Defined names are used to reference cells and formulas throughout the workbook to add a 'friendly name' to your formulas. You should check for any defined names that link to other workbooks or temporary Internet files. Typically, these links are unnecessary and slow down the opening of an Excel workbook.
You can use the Name Manager tool to view hidden defined names that you can't see in the Excel interface. Gba for mac emulator. This tool enables you to view and delete the defined names that you don't need.
If Excel continues to crash and hang after you remove any unnecessary defined names, move on to method 7.
Method 7: Links and hyperlinks
Excel's power is in its ability to bring in live data from other spreadsheets. Take an inventory of the file and the external files to which it is linking. Excel doesn't have a limit on how many Excel workbooks can be linked, although there are several issues that you can encounter. Test the file without the links to determine whether the issue is in this file or in one of the linked files.
Moving on
These are the most common issues that cause hanging and crashing in Excel. If you are still experiencing crashing and hanging in Excel, you should consider opening a support ticket with Microsoft.
More Information
If none of these methods made a difference, you should consider either moving to a 64-bit version of Excel or breaking your problem workbook into different workbooks.
