To check if the dimm is dead, remove all added ram and boot computer. It will tell you with
a number of beeps that it will not recognize the ram. If it is in fact damaged, desolder it. Just
take your time and use the right tools. If you damage it, it wont matter, its broken anyway.
There is no software hack to speak of, so its hardware all of the way. Good luck and keep us
updated on your progress and diagnosis.
