Intel Graphics 4000 + Discrete AMD Card = Crashes?

[Geofram]

I've got a system running an Ivy Bridge i5 3570K CPU with an AMD 7800 HD graphics card. It's been running just fine for quite a while. However, last week I looked into using Intel Quick Sync for my Handbrake encoding, so I enabled the Intel 4000 graphics and tested it out. I enjoyed the results, so I decided to leave both of them up and running, with one monitor hooked up to each.

However, ever since I enabled it, I've seen some odd crashes. Basically, once or twice a day, the system reboots itself (I assume some kind of blue-screen, but I haven't actually been sitting at the computer when it's happened).

I'm running Windows 8.1, and just reformatted entirely with things set up with both video cards just to make sure it was't something else causing the crash. Yet, it persists. Last time I checked the event log, it reported an AMD driver error just before things went down.

Has anyone else had this kind of trouble? I don't want to disable either one - the Intel 4000 is too slow for my games, but makes my moving encoding so much faster that I don't want to disable it; is this a known issue mixing the GPUs?

I get high cpu usage via system interrupts with a similar setup. Windows 8.1, 7950, z87...

Solution for me was to stop running the display off the hd4600 and then go to display -> detect -> look for Available Display Output on: Intel HD 4600 -> Try to connect always on vga -> extend -> hide it off your main display.


That will allow you to benefit from quicksync, OpenCl and MSI Afterburner QuickSync encoding.


Edit: A url that explains the process better than I can, and with pictures and stuffs.

I've just swapped over to using the "virtual" for lack of a better word monitor on the Intel display. Here's for hoping that helps. Thanks.
