I have been seeing many many people asking "How do I OC farther than CCC will allow?" So I will do this, so I don't have to keep typing it out!
To overclock beyond CCC limits, Download MSI Afterburner here: http://event.msi.com/vga/afterburner/download.htm

To use (properly) Install to your desired location. For simplicity, I will use C:\programs\MSI Afterburner. Yours may be different!
-Launch MSI Afterburner, then immediately close it!
-Navigate to the install directory, and locate MSIAfterburner.cfg (In my case for this guide, it will be C:\programs\MSI Afterburner\MSIAfterburner.cfg), and open in notepad.
-Change these values
     -"Enable Unofficial Overclocking" to 1 (Omitted on newer versions/combined with the EULA)
     -"Unofficial Overclocking Mode"   to 2
     -Then copy and paste the line below to "Unofficial Overclocking EULA"
I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
-save and exit
-Re-launch MSI Afterburner Enjoy!

Some helpful notes:
-This works on MOST if not ALL GPUs! You need not have an MSI GPU for this to work!
-Go to settings and set a custom fan curve
-If applicable, unlock voltage control and monitoring
-Save OC settings to a profile
-DO NOT CHECK THE "Apply Overclock at system start-up" BOX
-To set a low memory speed, you may need to lower the slider all the way down, hit apply, exit MSI AB, re-launch, and you should be able to lower farther. Repeat if necessary!

To run multiple GPUs
In the settings, there is a check box for "Synchronize settings for similar graphics processors"! Check that, then set your clocks/fan as you would for a single GPU! There is a monitoring screen to the right that will show: GPU1 usage, GPU2 usage, GPU3 usage etc. This monitoring window also shows temp, voltage (on some GPUs), fan speed, clock speeds, amongst others. You can also go into the settings and choose what you see in the monitoring window. The most necessary info would be % usage, temp, fan speed, but you could use any combination of parameters!

For individual clocking of multiple GPUs, you would leave the "Synchronize" box un-checked, then you can go into settings, at the top there is a selection bar. Select which GPU you want to alter, click OK!

Hopefully this helps someone out
