1 - I have a RX480 8GB and get ~300 H/s with 1250/2050. To get the max hashrate for your card, start at around 1200 MHz for the GPU clock and increase the value by 10-20 MHz until it won't start or is unstable, then back off 10 MHz. You can then do the same for the memory clock, adjusting by 150 MHz at a time to see if helps.
2 - I use Claymore's Zcash miner v12.4. Nothing else comes close for AMD in performance, but it does have an optional 2% dev fee built in. I use the miner to set the GPU, memory clock and intensity with the config for the miner. -i 6 works best for my RX480 8GB but for your card it may be less. You can also set the clocks and intensity individually per card in the config file. I use MSI Afterburner to set the fan speeds.
3 - I like dwarfpool's payout structure, but it's not as big as other pools so they find less blocks.

Dear Vann
Great !!! Im get 270 mh/s fr each RX 570 with 1250x1750
Im use Claymore 12.4 too with Minergate Pool, but minergate have multiples shares rejected
im had 3453 good shares and 69 shares Rejected in 56 minutes
Dwarfpool is better than this ?
Thanks
Almir
That's way too many rejected shares. I usually get less than 5 in a 24 hour period at Dwarfpool. They have several stratum ports and variable diff's for different rig sizes and multiple server locations so you can pick the one closest to you.
whar command line you are using to mine in dwarfpool?
thanks
almir
I use the .bat file that's include with the Claymore Zcash miner to start it. Open the start.bat file in notepad, remove what's already there and add:
Code:
setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
ZecMiner64.exe
Then in the config.txt add the settings for the pool and your card/cards and use start.bat to start mining. For my two cards, the config is:
Code:
-zpool zec-us1.dwarfpool.com:3336
-zwal
-zpsw x
-i 6,3
-cclock 1255,1235
-mclock 2250,1600
#-tt -65,90
#-a 2
#-powlim 50
#-asm 0
#-allpools 1
But you need to find the settings that work best for you.
