First of all the actual Vmod for this board is very complicated due to the fact that it is the only Asus boards using a digital VRM chip. This chip is capable of 3 different tables of voltage as you can see from the link to the PDF of the chip itself. As you read about the properties of this chip you will see that to actually change the table from a VRM10 table to a VRM 9 table can be done by an inline 50ohm resistors to the Vcore leg of the chip, or the resistor located off to the left of the chip itself. Now for the hard part, as you can see from the tables of the VRM 10 and VRM 9 there are digital codes (1’s and 0’s). You now need to rework what your 1’s & 0’s are. Example ….0-1-0-1-0-1 was 1.6v, but now on the VRM 9 table 0-1-0-1-0-1 actually adds up to a different voltage now 1.575v, and as you can see the last column has been dropped. Now you need the bios update that recreates the 1’s and 0’s table. Bios version Z7SWS0718.This bios is very hard to find for it was written for us by Asus. It is out there if you look for it. Finally there are to resistors to be swapped out to a 20k and a 40klocated to the bottom left hand corner of the VRM chip itself. I believe it is swapping the 56.6 to the 40k and the 26.2 to the 20k. I have included the link to the VRM chip below in the post. Good luck to all …NOW YOU HAVE A DUAL SOCKET PCI-E 2.0 SKULLTRAIL MOTHERBOARD WITH VERY FRIENDLY BIOS.
Oh…by the way the new bios allows you to set voltage to each core individually now under jumper free settings.
