easy captain, thats not true.
To conclude, there has been no evidence that the DFI NF4 motherboard has been responsible for any memory death. You can choose to not believe this if that is what you want to do. We have done extensive testing and found no evidence that the board kills memory modules though, and that is the truth, no matter how much some of you might want to flame and shout that you 'know for sure' that the board does kill memory.
the facts are that
some people are having problems with the ram dying, as if pushing 3.5v through ram 24/7 is a good idea to begin with. in particular, most people having this problem are using utt/ch5, not bh5 and vx chips. and for every one person complaining about this issue there are many, many others using the 4v jump without an issue.
the most important things to remember is the active cooling on the ram and if you use the 4v jumper you need to use the volts. meaning, don't set it to 4v jump and run 2.9v through it as the extra volts have to be discharged somewhere, ie through the mobo mosfets which obviously will burn the board up over time.
here is the thread on the issue. kinda lengthy but worth the read if you are considering that kind of voltage.
