My GPU WUs take a long time and frequently fail, and I think I've narrowed it down to nVidia's "boost" mode. I've tried several things, including nVidia's myriad tools, MSI Afterburner, and a few other software tools I'm now forgetting. None of them have allowed me to disable boost mode or adjust/limit clock speed in any sensible way. I've been avoiding messing with the BIOS just because of the risk factor.
Any suggestions on how to do this? If going the BIOS route is the only way, can you recommend a good tutorial/walkthrough?
