So I changed the value CPU-NB VDD Voltage in BIOS and checked Overdrive. In Overdrive that value is named NB VID.
From Auto value in BIOS for the CPU-NB VDD Voltage I went one step up, so it took me from 1.1000 to 1.1250.
Confirmed before that the stock was 1.1000 in Overdrive before the OC.
I ended up at 1.215 something in BIOS and booted up to Windows. Opened Overdrive and could see the NB VID changed to the BIOS value, but in orange mark, in BIOS I need to go much higher to see the red mark. In a strange way I could see a red mark on the Memory VDDQ. Changing the BIOS for CPU-NB VDD Voltage auto changed the Memory VDDQ values.

What I find strange is why my stock CPU-NB VDD Voltage is at 1.1000 when the this board stock runs at 1.2500

I'm having a hard time finding information in this huge thread. Tried searching, tried viewing several pages, but at nearly 1000 now, it's difficult.

Does anyone know if this board actually "supports" tri-fire? I have three 5870s in mine which Windows sees as well as Afterburner and GPUZ, however I seem to only ever have two cards enabled.

Yes it supports tri-fire, and it even supports quad-fire.  You might have to enable all of the cards in the Catalyst Control Center.

You will run in 8x.

I tri fired 3 5770s on it and ran fine for a while so yes it does.

Did any raise the VID voltages for your overclocks? VID are the startup voltages the CPU, MB... uses to fire up.

I have this motherboard MSI 790fx-GD70 and AMD Phenom II x6 1100t CPU
Is it possible to reach 4.1GHZ or more by OC the CPU?
It is stable with 4GHZ OC but if i try to get more like 4.1 or above it become unstable is it because of the motherboard or the heat? it didn't get above 49c I got the Cooler Master 212 Plus heatsink with and extra fan to cool the CPU

3.30 GHz / 1.325v = Stock Speed & Voltage
4.00 GHz / 1.375v
4.10 GHz / 1.425v = Max Stable OC

This board has a reputation of cooking the power delivery system when you have a highly clocked x6 in it. It's not really recommended.

It all depends on the individual board though.  I've had an x6 at over 5ghz and 1.7v on this board without any problems, but I've seen other people blow their vrm's at less than 1.4v.
