Title is self explanatory. Till yesterday tachometer was functioning fine, and today, it's stuck on "0" (zero). I even turned off the computer and back on, to no result... It's not that important, but it's odd that it worked before and not anymore... :\
Err, the Fan line is not connecting good? How about other software? Did they showing the Fan Speed? If other software is showing fine, then try uninstall, and reinstall MSI AB.
Software is Afterburner, of course. It doesn't show on other software too. No overclock. Drivers are 14.1 (14.2 gives me lockups) Fan line is connected, as I have never moved the heatsink (stock AMD). I also have not messed with ULPS... It started not showing it from nothing.
Just discovered why it wasn't working. It doesn't work with any of the 14's beta drivers. Moved back to 13.12's and it's all fine now.
