ZeroCore -- how to disable it?

[terpstra]

I understand the power savings benefits of ZeroCore, but I need to disable it. There's almost certainly an option somewhere, but I just can't find it! If someone could point me in the right direction, I would appreciate it.

The reason I need to disable ZeroCore is that SpeedFan sees the GPU temperatures as -999C after waking the graphics card up. I have already accidentally run a game at full GPU load with 20% fan speed (my configured minimum) for a few hours before realizing that SpeedFan had no idea of the temperature. Clearly this is a SpeedFan problem/bug, but I can't wait for a fix---there is a real possibility to seriously damage my system during this summer heat wave combined with a bit of negligence. Turning off ZeroCore will eliminate this risk until SpeedFan is fixed.

... I also have the sneaking suspicion that the "sleep of death" that my system sometimes enters is ZeroCore related. It wakes from sleep reliably without the graphics card installed.

Thanks a lot!

Just turn off standby so the monitor doesn't go to sleep.

Here's a piece of advice. Uninstall Speedfan.

The problem doesn't sound to be so much zero core as speed fan. Without the offending 3d party application, fan speeds would ramp as they should.

Assuming the reason you want to run speedfan this much a custom fan profile, you could try afterburner instead, and see if that doesn't let you have your cake and eat it too.

Use an older version of Speedfan that doesn't interface with ATI GPUs, Namely Speedfen v4.44.

Thanks. Turning on a screensaver and turning off "put display to sleep" seems to have done the trick.

To the others: I know the false readout is a SpeedFan problem. Still, I need it. My motherboard doesn't have fine enough control over the fans to handle my carefully tuned airflow. Also, MSI Afterburner cannot ramp up case fans in response to GPU temperature climbing, AFAIK.
