Hi "felinusz man. Got your PM man and the link and came and read the whole thread from beginning to the end and the few posts past yours here.
I am going to say exactly what I know and no more about this situation and will temper my personal biases against memory that requires so much voltage anyway. That said.
I would go and download this bios right here as it is the one going very fast to "official" status even as I type from its' beta status.

Download the bios. Throttle back and set 200 defaults and get off the 5.0 jumper to flash.
How to get on and off the +5V jumper? Pretty precise post by hovo73 to get on and off procedure rounded up.

Or in essence: 'copied from hovo73 post #113.
Ok back on the 3.2Volts settings and Jp17 is on the 3.3Volt rail for voltage supply and now flash the bios above and use ONLY the Yellow slots.According to DFI-Street when changing J17 position you should do the following:
Changing from 3.3V to 5V:

1. Go into Genie BIOS and manually set your vcore (cpu voltage). It MUST NOT be on Auto!
2. Save & exit. Return to bios upon reboot.
3. Verify that your vcore is correctly set. Save, exit, shut the rig down.
4. On the motherboard, move the 4v jumper in the upper corner of the board to the proper position (see manual/cd-manual/online manual for pics).
Boot up, go into Genie BIOS, do DRAM Voltage. Should now be adjustable above 3.2V.
Changing from 5V to 3.3V:

1. boot into bios and lower vdimm to below 3.3v
save & exit
2. boot up and see that the voltage 'stuck' to the new setting correctly.
save & exit and shut down
3. change vdimm jumper back to 3.2v position.
4. boot up and make sure vdimm is where it is supposed to be in the bios.
keep in mind that sometimes the voltages for vdimm or cpu 'stick'. Its very random and rare but I have witnessed it myself. Its a quirk. Clear CMOS and the voltages will return to their defaults and can be reset.
Note: here! Do not really care about how fast you can now go. If there is going to be any testing done and it is> you need to quit feeding the dang memory into a slot you think is killing memory until such time as testing is done. That is all I can say about that for you who have seemed dead memory.
Now that should get most back into safe territory even if they go back to the 5V mode according the procedure for change as shown above.
Now I have not seen this but have a tester that has had recording Oscope on the Vdimm and has not seen a spike as of yet. No he has not tested 15 motherboards but he still has seen no voltage spike.
Oskar is aware of this thread and is looking deeply at the bios as I type this. I am now awaiting UTT as I have NONE ; mainly because I don't really like it but nevertheless am getting some for testing. When UTT arrives will setup and get running with Bios 510-2 as linked above and put sticks in Yellow slots (1 and 3) and start to running at High Volts and at as much FSB as it will do and let run prime or some other proggie to load the system and see if any problems surface from Yellow slots (1 and 3) and also to be able to test any beta bios Oskar hands me for test against his findings.
Now other than that I have no frikken clue and will not speculate. I have said all I know and will say. No guessing and jumping to any mind blast I may have come to me.
Thank you, "felinusz" for giving me heads up man. Did what I said I would do when you asked.
RGone...
