M4500 GPU Overclocked 880m

Sorry for the super late response guys. Here is the link for the latest version of nVidia System Tools and here is a link for GPUTOOL. GPU Tool was never finished and thus not a final release but I find that it works fine and prefer it if you want to switch back and forth between default speeds and OC speeds. GPU Tool also has an option to scan for artifacts. I recommend you let it scan for at least 5hrs. Probably best if you let it go overnight to make sure it's stable.

For monitoring your GPU I suggest GPU Observer. It's the best gadget I've found that doesn't require something like Everest to run in the background and suck up system resources.

I used HWMonitor to check my temps while testing. Watch for atifacts and heat. If you see either, immediate lower the settings. And as always, raise the clocks slowly...and test for expended periods. Dont forget to load the CPU as well as the GPU during testing cause when you play games it will rarely not use the CPU which shares a heatsink with the GPU on the M4400 and will significantly increase temps. A good one to use to stress the CPU and RAM is ORTHOS CPU Loader Just run a blend test. Watch your CPU usage. If there are unused cores open up another instance of ORTHOS and run the Small FFTs test to stress the other CPUs. Repeat until all CPUs are at 90-100%.
