Hallo,
System: 6xSAPPHIRE NITRO+ RADEON RX 470 8G ASRock H81Pro BTC 2.0 Mainboard LGA 1155 Intel Celeron G1610, 2x 2,6GHz 4 GB RAM Super Flower - Leadex Titanium 1600W Netzteil Windows 10 Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.1
I measure the power consumption with a calibrated electricity Watt meter
691 Watt / 168,5 MHS
-> 4,1 Watt / MHS
get someone better efficiency?

2100mhz is impossible at 40W. Not hard or difficult, impossible. The lowest you can get on GPUZ for 2100 would be 80W. Now, every card is different, if you get lucky you get a good piece of silicon that can touch 2100mhz. If you are unlucky, it may not cross 1900.

Now, every card is different, if you get lucky you get a good piece of silicon that can touch 2100mhz. If you are unlucky, it may not cross 1900. Mem clock has little (not nothing, but little) to do with overall wattage. You're looking at core - which is responsible for most of your draw. Interesting. Some tests are in order then I suppose to see if we can get to a GPUZ reading of 40W, at any clocks. Will report back soon.

Hello everybody,
Sorry for the stupid question, but the post is very long. Is there a link in the 33 pages where it is described how to install the mod graphics bios mod or change the settings with which tools?
I bought yesterday 6 graphics cards and will read the faq's before the cards are here :-)
6x SAPPHIRE Radeon RX 470 Nitro 8GB OC (11256-17-20G)
What values can I expect at ETH Mining, at which power consumption
Greetings from Germany Willi
