You can if you like but it's not necessary. As long as you're below the power limit you're good. You can try and increase the voltage to maximum to see if you can run 150+ on the core.

1.212v. Make sure your fans are at maximum when running the voltage at max.

You can try increasing the power a little bit at a time, or you could just go straight to max, whichever you prefer.

Yep.

Should I go for the last 25%?

I went ahead and put it up to 100.  Power and temps were about the same as default.  Didn't work for 150+ on core.  I guess 100 is as good as it gets on that?  I'm still at 250 on the memory so maybe I still have some headroom on that?
 
Should I just leave the voltage on 100 then since I didn't get anymore out of the core with it?

Since you didn't get more core with voltage at max I would suggest you put the voltage back to stock. Having the voltage at max isn't going to help your memory overclock as the voltage is mainly for the core.

I would have thought increasing the voltage would have increased my temps and power usage but It didn't seem to.  Thanks for your help I will try more overclocking with the memory then. 

If you didn't see an increase in temps it's likely because the BIOS already has it set at 1.212v already. You can see the voltage in GPU-Z. (VDDC)

Hey I noticed in the Afterburner properties when I had checked "Unlock voltage control" off to the side it says Standard MSI, reference design, extended msi.  I had it on standard MSI when I had tried upping my core speed past 100 and had crashing.  Maybe standard MSI doesn't allow for increased voltage past stock?

Yes try it.

What about unlock voltage monitoring?  I have that checked is that one necessary?

Nope.

How come my power usage on my cards is around 70%?  I would think it would be maxed out right if I am utilizing 98% of the capabilities of the cards but why would the power only be 70%?  I have read through a bit on the overclock.net forum where I had downloaded the Skyn3t bios and other people seem to have to increase the power limit to allow past 100% TDP.  What is special about mine?
 
I checked out the ASIC value of my cards.  My first card was 61.5% and the second card is 79.5%.  Don't know if that makes any difference. 

Most likely because of the game you're playing. Try running 3dmark11 using performance preset with display scaling mode set to stretched, you should see your cards use over 70% usage. My cards use around 90 to 100% when running 3dmark11.

3000 watts if your name is Vince.
 
If you're a normal person, 1200 watts should be sufficient, even with light GPU OCs.

Question for Sajin:  I don't have this 3rd card yet but I have noticed ever since I installed the Skyn3t bios my cards seem to run full tilt even at the desktop with nothing going on.  Consequently my fans on it are at like 75% speed.  I first noticed because I kept feeling "wiffs" of warm air hitting my face.  I figured it out that it was my GPU's running nearly full speed.  It is either the Skyn3t bios or the new precision X.  I got rid of after burner and went with Precision X not long after installing the skyn3t bios.  Is it normal for either of these to cause that?

The card should downclock to idle mode even with the skyn3t vbios. It may be the new precision x. Do what bdary said to see if it's related to PrecX.
