may be challenged and removed. (June 2011) (Learn how and when to remove this template message) A Machine Check Exception (MCE) is a type of computer hardware error that occurs when a computer's central processing uncorrectable processor machine check exception unit detects a hardware problem. Modern versions of Microsoft Windows handle machine check cpu 1 machine check error detected exceptions through the Windows Hardware Error Architecture. When WHEA detects a machine check exception, it displays the error in a

Similar errors may occur on other processors and will cause similar problems. Some of the main hardware problems that cause MCEs include: System bus errors: (error communicating between the processor and the motherboard). Memory errors: parity checking detects when a memory error has occurred. Error correction code (ECC) can correct limited memory errors so that processing can continue. Cache errors in the processor. Possible causes[edit] Normal causes for MCE errors include overheating and/or incorrect hardware installation. Specific manually-induced causes include: overclocking (which normally increases heat-output) poorly-fitted heatsink/computer fans (the same problem can happen with excessive dust in the CPU fan) an overloaded intern

is an error generated by the CPU when the CPU detects that a hardware error or failure https://wiki.archlinux.org/index.php/Machine-check_exception has occurred. Machine check exceptions (MCEs) can occur for a variety of reasons ranging from undesired or out-of-spec voltages from the power supply, https://software.intel.com/en-us/forums/intel-firmware-engine/topic/603829 from cosmic radiation flipping bits in memory DIMMs or the CPU, or from other miscellaneous faults, including faulty software triggering hardware errors. Contents machine check 1 Installation 2 Configuration 3 See also 3.1 Hardware documentation Installation Install the mcelog package. mcelog written by Andi Kleen is one of the tools to gather MCE information. Configuration mcelog's configuration file is located at /etc/mcelog/mcelog.conf. See man mcelog, man mcelog.conf and man mcelog.triggers for machine check error more information. Start and enable mcelog.service. By default, the service runs mcelog as a daemon.

Wed, 12/09/2015 - 16:04 Hello, I have a custom board(RC10), which has E3845 and is similar to MinnowBoard MAX. I have customized from Intel Firmware Engine MinnowBoard MAX firmware to RC10 by enabling i2c-0, PCIe-2, etc. When the Linux system boots, it shows "mce: [Hardware Error]: Machine check events logged" 300 seconds after the boot. 1. Since the original configuration came from the MinnowBoard MAX, which uses E3825, the mce error might come from it. If yes, how can I change the processor to E3845. 2. Other than #1 I don't have any idea where the mce error came from. Is there any way to track it down by disabling HW components(e.g. PCIE-0)?

Log in to post comments Brian Richardson (Intel) Thu, 12/10/2015 - 11:22 We'd like to get the log of the machine check exception to figure out what's going on. On Linux systems, you should be able to get this using mcelog - http://mcelog.org/ As an example you can install this on Ubuntu/Debian using apt-get: sudo apt-get install mcelog The events will be logged to /var/log/mcelog. You can also run: sudo mcelog --client to query the mcelog daemon for errors. -- Brian Richardson -- @intel_brian Top Log in to post comments JONG L.
