A lot of the time people do not run the proper tests. They'll run their favorite
game/app for an hour and think all is well. In reality, they could have massive
memory errors. I've actually seen this happen before. I had a stick of ram start
dying on me. My rating on FICS kept dropping and dropping, finally the program
itself started to crash. Tested with memtest.. sure enough, ram kicked the
bucket. Put in a new stick and all was fine, rating went back up to normal.

It is a good idea to verify that your overclocked settings are alright with
burnk7, prime95, memtest86+ at 15C over your normal running temps. Once that is
done clock it back 5% or so and you'll be fine.

As far as overheating goes.. never seen it cause a problem. Usually any
overheats cause massive sudden problems. Completely locking up the computer or
crashing the program. Generally unstable/bad ram corrupts the hash tables and
thats what will do it.
