How to use AMD Display Library (ADL) Overdrive State Set function (for overclocking programmatically)

Question

I'm using AMD Display Library which basically allows us to control certain parameters of the GPU (Clock Speeds / Fan control).

The SDK comes with a Sample-Managed code and I was able to get the required result (Core and Memory clock speeds) from ADL_Overdrive6_StateInfo_Get method.

Using the ADL_Overdrive6_State_Set method (which has the same parameters) returns an error code:

int od_result = ADL.ADL_Overdrive6_State_Set(OSAdapterInfoData.ADLAdapterInfo[i].AdapterIndex, ADL.ADL_OD6_SETSTATE_PERFORMANCE, stateInfoBuffer);

-8 ADL_ERR_NOT_SUPPORTED (Function not supported by the driver.)

I've tested it on a system with AMD Radeon R9 280x / AMD Radeon HD 7970 and a laptop with AMD Radeon 8670M.

Do I need to change something in the driver settings and is there a compatibility issue?

As @novaterata stated in the comment that I could try using the 7.0 library but I moved on to use the Afterburner API http://forums.guru3d.com/showthread.php?t=339656

Contacting AMD didn't help.
