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).
  5. Boot up, go into Genie BIOS, do DRAM Voltage. Should now be


Changing from 5V to 3.3V:

  1. boot into bios and lower vdimm to below 3.3v
  2. save & exit
  3. boot up and see that the voltage 'stuck' to the new setting correctly.
  4. save & exit and shut down
  5. change vdimm jumper back to 3.2v position.
  6. boot up and make sure vdimm is where it is supposed to be in the bios.
  7. 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.

You can shutdown the PC when you are in BIOS? That is something that interested me, because it is recomended to do it aimmediately after flash and I have a thing about shuting down the PC while it is posting. Is it safe to shut down the PC (using the switch) when it is in BIOS?
