i got problems with my template too. tried again today morning.. it works basically, but i also get those stripey screens now and then, lock-ups and the red led lighting on the card. i found that v gpu reads 0 if the screen goes black, and below 800mV if those stripey screens occur.

I as well think that its some interference with driver-side powerplay profiles that get mixed up.. for me, i would only need lower voltages in bios and the opportunity to overclock via ccc. then i'll apply pencil and lower voltages in bios and overclock with ccc. until thats possible, i'll go with amd gpu tool i think.. or, lowered voltages in bios + pencil and ATT, with which i can possibly then use higher voltage and higher clocks.. will try that out..

the decrease voltages is meant for 4870 i think as 1.201v is actually more then 4850 stock vgpu.. that led to blackscreens here as well..
