A second GPU-Z log, this time pushing a bit more
In this new log, I pushed the video card a bit more. We can see there is an
sclk 500MHz with a mclk of 650MHz (VDDC @ 1.063V), another intermediate power
level using a sclk 500MHz with a mclk of 1300MHz (VDDC @ 1.063V) and finally a
last power level using a sclk 830MHz with a mclk of 1300MHz (also using a VDDC
@ 1.063V).
So, we are missing power level under Linux AND we are not using the same VDDC
above the lowest power level. This fact could also explain why we had to limit
sclk and mclk (800MHz and 1250MHz) on cards that are not using stock speed
(overclocked cards, like mine) if we were not using a high enough VDDC, isn't
it?
