cpuburn is your friend to test the stability of a new or changed system. 
Finds mmx/memory-transfer errors on broken mainboards/cpu's. It's designed to 
produce maximum heat/load on each cpu and finds errors by comparing calculated 
and expected results. 
Example: i found, that my old mainboard (labeled FSB133) did not reliable work 
at 133 MHz FSB although the right memory was used (tested with 3 different RAM 
chips), with 100 it was (almost) stable. 
 
Typical userware might not be suitable for that job because of: 
1. not stressing enough (look at the cpu-temp when cpuburn runs - it jumps 
+10°C almost) 
2. most times the errors are not detected because the software just runs on 
producing wrong results, video glitches etc. but does not crash most the time
