Hardware Error Machine Check Exception
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 machine check exception error unit detects a hardware problem. Modern versions of Microsoft Windows handle machine check

exceptions through the Windows Hardware Error Architecture. When WHEA detects a machine check exception, it displays the error in a machine check exception fix Blue Screen of Death, with the following parameters (which vary, but the first parameter is always 0x0 for a machine check exception): *** STOP: 0x00000124 (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000) On Linux, a

Most MCEs require a restart of the system before users can continue normal operation, and indicate a long-term problem of a general nature. Contents 1 Problem types 2 Possible causes 3 Decoding MCEs 3.1 Programs to Decode MCEs 4 See also 5 References 6 External links Problem types Most of these errors relate specifically to the Pentium processor family. 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 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 o

Bascailly its giving me hardware errors locking up. Im thinking it might be bad ram, so im doing a memtest now but i just want to double check as i dont fully understand the message its giving me.[img]http://i.imgur.com/7pRQD.jpg[/img]Any input would be appreciated!

X86 CPUs report errors detected by the CPU as machine check events (MCEs). These can be data corruption detected in the CPU caches,
in main memory by an integrated memory controller, data transfer errors on the front side bus or CPU interconnect or other internal
errors. Possible causes can be cosmic radiation, instable power supplies, cooling problems, broken hardware, or bad luck.
Most errors can be corrected by the CPU by internal error correction mechanisms. Uncorrected errors cause machine check exceptions
which may panic the machine.
When a corrected error happens the x86 kernel writes a record describing the MCE into a internal ring buffer available through the
/dev/mcelog device mcelog retrieves errors from /dev/mcelog, decodes them into a human readable format and prints them on the standard
output or optionally into the system log.
Optionally it can also take more options like keeping statistics or triggering shell scripts on specific events.
