Overclocking my HIS Radeon 6990 ?

post #1 of 2
Thread Starter 
I have some problems to get the 1000MHZ gpu stable

I use the MSI Afterburner and my maxium is 995MHZ with 1,25Volt.

How can I set 1,3 Volt with the MSI Afterburner?

I set

UnofficialOverclockingEULA I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode 1

but the maximum voltage did not change still 1,25Volt as maximum.
What did I wrong ? With the UnofficalOverclocking I can set the GPU to 1320 but this don't make sence without a higher voltage.

Do you have an idea to unlock the maximum voltage ? Or do you have some OC Bios ?

(sorry for bad english)

1. Click on "settings" in the bottom right corner after MSI Afterburner is started up. ( It's not hard to find.)

2. After clicking on "Settings" go down to "Safety properties" and select "Unlock Voltage Control" and "Unlock Voltage Monitoring".

Try that and see if it works
