Awesome. I asked about this because the Mosfets are optimized for 5v and when went to 7 volts to 6 volts the VRM heat sink felt much cooler. So then I was really intrested in the 5 volt option.
Now if you can implement the latest RAID ROM, I be a really happy camper.

I was using the 1201 R4F bios, i had to switch back to 1005, due to prob's with the 3 way gpu setup i was running..

7V is about the optimum for balance between dissipation between the driver (not heatsinked) and FETs. Around the midpoint for a 5V VGS also.
