When the AMD 500 series came out, I bought up a number of 470 8g cards in desperation. Most of my experience has been with Sapphire nitro+ rx 470 8g cards, and in my haste I bought a number of Sapphire nitro rx 470 8g {not the + version} and so far I have come to the conclusion that they suck ass. I can't seem to mod the bios without them not responding, and almost any moves I make with voltages makes them unstable. I have read this whole forum and saw that others have had these same issues, but I didn't find any clear success stories either. There was a lot of talk mid to late last year about these cards, so I am hoping someone has figured out a way to get these cards up to 27-28 MH/s with a wattage lower than what I am getting at 24 MH/s. Any real life solutions are appreciated. I simply want them stable and using less power at an average hash rate. I am not looking for miracles, but perhaps a bit of hope would be nice. I have spent hours and hours trying to get these cards to a better level of performance to no avail. I appreciate any consideration.
I was able to mod this cards to work smooth 1170/[email protected] ->70w gpu-z. The speed is slightly more 29mhs eth.I think I could do better but don't want to waste whole farm time for experiments - pity I have no standalone test system yet
Please share your speeds and settings after Wolf's mod
