These are some Claymore settings for RX 470's. The rig is currently running a mix of Rx 470 gaming x 4g 4gb and Armor 4g 4gb cards.
The miner is running windows 10, Claymore Version 10, and the latest AMD Mining drivers. The mining drivers made a HUGE difference. Download the drivers here. http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Blockchain-Compute-Release-Notes.aspx
I got 25 Mh/s for each Armor card and 28+ Mh/s out of the Gaming X card. I get about 4x that hashing power with DCR dual mining.
##Options 1
-cclock 1100, 1100, 1100
-mclock 2000, 1750, 1750
-cvddc 850, 890, 890
-mvddc 800, 800, 800
mclock 1750 is for the Armor cards and the 2000 is for the Gaming X cards.
If you have stability issues, lower mclock by 50 at a time until it's stable.
cvddc 890 is for the Armor cards and 850 is for Gaming X cards.
-asm 1 (See Calymore readme. 1 is the best option for the 470's)
-dcri 4 (This increases Alt coin mining. These cards do not dual mine that well. I wouldn't set this beyond 4.)
-mode 0
-ethi 16 (This takes gpu power away from Windows and applies it to mining)
-tstop 85 (This stops the miner if it a card reaches 85 degrees Celsius)
-tt 75 (This is the target gpu temperature. You want it low enough to not damage the card, but high enough to not overwork your fans)
-fanmin 30 (This is to keep the fans from turning off and on. my fans still stop sometimes)
-fanmax 100 (Allows the fan to reach 100%. Not really a necessary setting)
-ttdcr 83 (This tunes down my alt coin DCR mining if the cards reach 83 degrees Celsius)
-minspeed 60 (This restarts claymore if the total Mh/s goes below 60 Mh/s)
-powlim -20, -20, -5 ( -20 for one armor AND the gaming x, but one of the armors only worked at -5. This lowers the amount of power that goes to each card. This setting saves a ton of money, you want to go as low as possible)
-r 1 (This restarts the entire miner if a gpu fails. See Claymore's Readme. you'll need to create a reboot.bat file)
-mport -3333 (This is for remote management. I dont really use this)
-esm 0 (Eth proxy mode. 0 is best for nanopool and dwarfpool. If you're having issues with your pool, this might be why)
-gser 2 (This buffers the ram before you start mining. I was able to push my cards much harder after applying this setting)
-allpools 1 (this has to do with devpool mining, which is your dev fee. If your devpool mining isn't working, it'll stop your entire miner)
-allcoins -1 (This allows you to mine Ethereum forks by setting the epoch for you. The disadvantage is that it starts the miner by first mining your dev fee.)
