You can try disabling RC6 (which lets the GPU go to a deeper power state). That might lower some throttling you are experiencing. As far as I know there is no way of locking the GPU frequency. I will find out more and post here if there is a better way.
Thanks,

Hi
I would like to know if the HD Graphics 4600 and Iris 5xxx series can be sustained at maximum clock frequency of 1GHz and above.
What are the conditions under which the Graphics stays at max clock? Is thsi sustained if we ahve have heavy processing happening on the 20 or 40 cores of HD Graphics.
Regards
Murali

Thank you for your answer. Disabling RC6 works well, according to GPU-z, the frequency of the HD4000 remains at 1.25GHz all the time. It would be nice to be able to change it from the graphic properties, but this parameter is not supposed to be changed that much. The temperature seems to stay acceptable too (~70-80 C). Thanks, Chris
Hi, christolb29:
Happy new year!
I would like to know how to disable RC6 under windows 7, could you give me some hints?

Hi Biao W,
Happy new year too.
As I remember, you should be able to disable RC6 directly from the BIOS.
