by chance I saw the reddit link and guide so I tried it out and my results are a little different. I used the "1100MHz HBM @ 905mV" reg file and this is what I got.

so far, the highest hashrate for eth is about 43mh/s but my lcd is connected to this card with other software running as well. so this might have impacted performance.
hwinfo shows gpu core using 68w, mem 21w
I manually changed the p7 core clock to 1221mhz in wattman
Could be a reason if you run any other software. Not sure that hwinfo shows the right information about, use any Watt meter device at your power cord is better. One important hint - use the OverdriveNTool version 0.2.1 beta - it has direct access(press right mouse button at the tool) to the powerplay area in the registry, so you can adjust some values directly(after that reboot the settings are active) - you must start this tool with admin rights to get access to the registry. Have fun.
