Hi everyone, I have a question about GPU-Z and my Radeon 7850.

Thing is that VDDC showings are not constant and there are huge current and voltage jumps.
Please look at this screens and notice how VDDC graphs are not constant

As you can see the highest VDDC Current jump was 255A when playing Witcher 2 with ubersampling (for testing purposes)

I also have a log file with 112, 120, 130, 190 and 200A jumps which seemed to increase as I was running Unigine Benchmark.
There were also lots 1.564V Jumps during Unigine (1.7 max during Witcher...) while its 1.064-1.066 most of the time.

Is that normal?
Maybe this is the cause of my blacksreens during gaming when my monitor looses power requiring a hard reset?
