I,
I just found out that the MCLK was stuck at 300Mhz on my Polaris10 card. I got
the card last week, I don't really know if it's new. I have git version of
linux, mesa, libdrm.
I can force the power to high and get the proper 2000Mhz and when I set it back
to auto, it go back down to 300Mhz, halving my EVE-Online fps by about 200%.
The SCLK is normal, It move according to load on auto and move according to
crappy cooling on high.
I got some error in the dmesg too, can be related, or no.., I attach them.</pre>
