Machine Check Exception efter långvarig överklockning?

Jag behöver råd from vanare överklockare om ett felmeddelande jag emellanåt får. För ungefär ett år sedan skaffa jag en Sandybridge 2600K och överklocka den till 4.4Ghz@1.3V. Jag loadtesta med prime95 några nätter och allt funka fint. Temperatur var runt 65C. Jan 19 i år fick jag en Machine Check Exception med felet "Generic CACHE Level-2 Generic Error" men efter omstart gick allt fint. Igår fick jag en till Machine Check Exception men denna gången kunde ingen human readable felsträng decodas.

Vanligt förekommande problem vid överklockning? Lösning?

"Causes

Normal causes[clarification needed] for MCE errors include overheating and/or incorrect hardware installation. Some specific manually induced causes could 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 internal or external power supply (fixable by upgrading)

Computer software can also cause MCE errors (normally by corrupting data which programs read or write). For example, software performing read or write operations from or to non-existent memory regions can lead to confusion for the processor and/or the system bus.[citation needed]"

"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 that may include parity / Error correction code (ECC) problems. Error checking ensures that data is stored correctly in the RAM; if information is corrupted, then random errors occur.
Cache errors in the processor; the cache stores important data and code. If this is corrupted, errors often occur."
