    Unless you mod the BIOS - you can't.

    The BIOS for my Precision 5510 (essentially the same as the 9550) has a switch in the BIOS to enable / disable hyperthreading. In fact, I've had hyperthreading disabled for months as I prefer the lower fan noise arising from full CPU load with only 4 threads, not 8.

    The machines that I have owned don't appear to have such an option. Then again, I didn't exactly look for it and just assumed it wasn't possible. Error on my part.

    Enter BIOS, on the left hand menu expand "performance" then click on "hyperthread control" and disable it.

    You know the chance in this causing a BSOD is next to nothing unless running a CPU benchmark that triggers it?

    This is why it took so long to come out.

    Just don't do it. I predict a chance of 0.0001% the bug will ever happen to you, since it's exclusive to a very limited list of apps/games which use more than 4 CPU cores and will actually trigger the malfunction.
