For the Claymore Miner v 12.4 using 4 Sapphire RX470 Nitro 4GB, I am using this bat:

ZECMiner64.exe -zpool ssl://zec.supernova.cc:2242 -zwal username.worker -zpsw password -i 7

Im only getting about .15 zcash every 25-26 hours

What can I do to improve performance? Miner speeds read 276 - 288, Driver date 3-16-17 version 21.19.525.258.

What tool are you using to tune(OC/UV) your cards?

for a quick workaround if I'm starting from a fresh driver install I reduce CPU Freq by ~13-17% and then undervolt your top 2 clocks to ~940. So, it'd be around 1020 @ 940, duplicate the second highest rate to the same, then go back through all the voltages and just duplicate 940 until you reach an actual value that has been automatically tuned down to roughly the same voltage and then just save that.

so..

-asm 1 / works well for my Strix 470, however my Nitro+ 480 seems to work better when set via -a 0
-tt 0 / if you are setting your fan temps in Wattman or other Software
-i 4,5,9 - test out how the speed differs between -i 5 and your current -i 7. I get better RX480 speeds using -i 5/-i 6 than -i 7/8/9. -i 7 is usually good for the 470 tho.

-> -12.5% CPU Frequency -> Manual Voltage -> reduce down to at least 990 or lower.

-> Memory Clock -> Increase to 1900 -> Undervolt to 960.

-> Give all cards some Additional Power if possible, it keeps the RX470's from becoming 'complacent' when finding shares.

I run that kind of configuration on my Strix 470 and I hash at 300 with -i 7 and -asm 1...

HOWEVER - these are only a few things that work for me, running 1x RX470 along side 2x nvidia cards and an RX480, so I found the Undervolting kept the 470 under 55 degrees C while hashing @ 290-300.

You might just want to cranking up the memory frequency and core frequency and just cutting down the Core voltages by 100 or so.. then get the fans running fast.. Shit, I dunno - you're pretty much bottlenecked by how well the 470/AMD drivers interact with the equihash algorithm - so experiment then just wait for Software updates.
