Overclocking MSI HD 6770

post #1 of 5
Thread Starter 
Well as the title says... I'm just trying to get a little better performance out of my cheap card.

940mhz on the GPU seems to be my limit so far and anything over about 1240 on the memory causes a slight screen flicker (but no error)

So I'm just wondering if its possible to overvolt it (afterburner keeps it grayed out) maybe I need to do something special other then clicking the "unlock voltage control" ?

Yup, you should be able to overvolt that GPU with MSI Afterburner. It's what I use and I love it. Start with very small bumping in voltage and watch those temps! To my knowledge, to overvolt you also have to change a setting in the .cfg file of afterburner. Lemme look.

You should try this one: it worked for me.

"We're receiving emails on how to enable additional overclockability for AMD cards (if supported) in MSI afterBurner.

To enable the unofficial overclocking in this version it is necessary to edit the MSIAfterburner.cfg file located in the installation directory of AfterBurner (typically Program Files (x86) MSI Afterburner):


You need to alter the following:

Seek UnofficialOverclockingEULA field and add following text:

I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
Set UnofficialOverclockingMode to 1 to keep PowerPlay active (may not work on old ASICs), 2 to traditionally disable PowerPlay or to 0 to temporary disable unofficial overclocking path

Using the unofficial overclock method opens up more freedom in terms of voltages and clock ranges, it however also can open a can of worms in terms of stability or weird issues.

Unofficial means unsupported -- we grant some extra tweak options to fool around with, but in no way, manner or fashion is it supported by Guru3D.com or MSI.

So asking questions about it in the forums .. is a no-go. Regardless, have fun with this feature and be careful to not push the card over its limitations."

Thanks for the help but for some reason even using MSIAfterburnerVoltUnlock and manually changing the voltage control values in the .cfg file won't work.
But the unofficial overclock stuff did...max setting of 1210 on the GPU and 1405 on the memory.

Trying to check around see if there is a bios issue here..


FYI
this is a HD 6770 (MSI r6770-MD1GD5 to be exact)
