99.99% of the IRQL BSOD's I've gotten and heard of other people getting
were easily resolved. The message would make more sense if it said:
 
  "You have bad memory. This memory will pass any test you give it, but
   fails under the load of a real system." 

I've even run memtest on memory with the deepest possible test for a week,
and had it IRQL within minutes under Windows. The same memory ran for months
on linux before failures showed up. Once they did the computer would not boot,
so it really was bad.
