I bought an MSI Radeon R9 270X BF4 edition last week and have been experiencing shutdown/restarts. They are showing as Event 41 Kernel-Power in event viewer with no BSOD's or minidumps being created. My computer ran fine when it was idle at 300/150MHz clock speeds and I have managed gaming sessions and stress tests when it was at 1080/1400MHz, but the restarts have occured when I have been watching Twitch streams and watching videos on my 2nd monitor, this looks like it is caused by the clockspeeds increasing to 450/1400 for a few seconds and then back down to 300/150.

At the moment as a temporary solution I am using the MSI Gaming App and gaming mode and keeping my clocks at 1080/1400 to keep my computer from shutting down. Is there anyway I can change the minimum clock from 300/150 to 450/1400 which it keeps on jumping to while I am watching twitch?

I have reinstalled drivers to latest, ones that came with card and I am currently running the latest Catalyst beta driver. I have updated my MOBO Bios and all chipset drivers. Updated my SSD to latest firmware. Ran memtest86+ overnight for 8 hours and 5 passes with no errors being found. All my temperatures are normal while idle and while gaming.
It only shuts down when I am either running multiple browsers on both screens or watching videos/streams on my second monitor for which the clocks of the graphics card will jump up to 450/1400 for a few seconds before back down to 300/150 and will keep on flickering between the two frequencies. Like I said at the moment I am using the MSI Gaming App in gaming mode to keep the clocks at 1080/1400 and my computer doesn't shut down.
