Thought I would add some info Jimmy at DFI was kind enough to forward to me. Kris could add this to a guide also if needed
Over the next day or so i will explain what we have here and how to use the tables.
Big thanks to Jimmy at DFI here for the info.
EDIT 1 the top table.
This table pretty much shows what happens when you leave GTL's at auto and change VTT. All the time though GTL's will show at 110,
It is recommended you follow this table manually if you choose manual as this table closely follows Intels spec's
Next table shows what bios has as options for VTT and what is actually set.
The bottom tables show the relationship of VTT and GTL...An example is setting VTT to 1.2 and GTL to 115 will give 0.86V but with VTT at 1.5V 115 gives 1.05V
