lock/underclock Haswell iGPU?

This is a bit of an odd request I guess, and counter to what most people would prefer to do... But is there a way to underclock or at least lock the clock and memory speeds of the iGPU?

I'm on a tablet PC (Dell Venue) with an i3-4020Y, and using any browser causes the GPU to kick into high gear when I'm scrolling long pages. Normally this isn't a problem but on a hybrid device that often translates into the CPU+iGPU getting unnecessarily warm and the fan kicking in. I have no need for the iGPU to be running at full speed on this machine, and I don't even play games on it, so I'd like to keep it to the minimum (200MHz) at all times.

Is this possible? I've tried with MSI Afterburner (3.0 beta, Mar 27 2014), but couldn't touch any of the settings. It can read the iGPU just fine, but I can't access any of the Core or Memory clocks to lock them down.

Thanks!

 

Any controls would be more suited to the likes of intel XTU, but the reason the GPU kicks in is scrolling the pages smootly is an effort, if you want to save power you could turn off GPU acceleration of the UI, but this will make your CPU work harder instead.

 

Yeah I considered that, but for the same reason you explained already disabling the GPU acceleration just puts off the workload on the CPU. I basically want to limit my iGPU's clock speeds because I simply don't need it to be spinning up to 650/800 when I'm scrolling a web page or a PDF document.
