In this example, 03 is the month, 11 the day, 20 the year, and -01 the number of the dump file.
Windows 10 creates only a minidump file
If you notice that your Windows 10/8 device that uses SD eMMC memory creates only a minidump file then this post will help you. The term eMMC is short for “Embedded Multi-Media Controller” and refers to a package consisting of both flash memory and a flash memory controller integrated on the same silicon die. The eMMC solution consists of at least three components – the MMC (multimedia card) interface, the flash memory, and the flash memory controller – and is offered in an industry-standard BGA package. Today’s embedded applications such as digital cameras, smartphones, and tablets almost always store their content on flash memory. You’ll encounter this issue on a tablet device that’s running Windows 10/8.1/8 and that uses SD eMMC memory – Windows produces only a minidump file, even if Kernel memory dump or Complete memory dump is configured under Advanced System Settings > Startup and Recovery. The minidump file is saved to the %systemroot%\minidump directory instead of to the standard C:\windows\minidump location. This issue is caused because due to the aggressive power management on SD eMMC devices, Windows always creates a minidump and ignores the memory dump settings that are configured by the administrator. To override this default Windows behavior, a special Registry setting must be configured on the device. You can follow the steps outlined below to override the Windows eMMC power-saving feature during a BugCheck (also known as a Stop error or a blue-screen error) in order to produce a kernel memory dump or a complete memory dump. Before you begin, since this is a registry operation, it is recommended that you back up the registry or create a system restore point in case the procedure goes wrong. Once you have taken the necessary precautionary measures, you can proceed as follows:
Press Windows key + R. In the Run dialog box, type control system and hit Enter to open Advanced System Settings > Startup and Recovery, the Write debugging information option must be set to Kernel memory dump or Complete memory dump.
Next, proceed to Launch Registry Editor to create and configure the following registry key: This registry setting permits the dump file to be written.
Navigate to the registry path below.
Then right-click on an empty space on the right pane.Select New > DWORD (32-bit) Value.Name the key ForceF0State.Double-click the newly created key and set the Value data to 0x1.Click OK.
- Next, create and configure the following registry key: This registry setting makes sure that the dump file is not deleted upon reboot, even if you’re running low on free disk space.
Navigate to the registry path below.
Then right-click on an empty space on the right pane.Select New > DWORD (32-bit) Value.Name the key AlwaysKeepMemoryDump.Double-click the newly created key and set the Value data to 1.Click OK.
Make sure that the maximum page file size is larger than the amount of RAM that’s being used on the computer. Check this under Advanced System Settings > Performance > Advanced. The virtual memory paging file size setting on the system drive must be larger than the amount of RAM that’s being used.
Restart the device. This should help!
