Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[max72]

benz0, I am using Sapphire Trixx 3.0 for adjusting. 

So, I went with this so far: 
Original:  GPU Clock:  1236, Memory Clock: 1750, mV +0
Adjustment #1:  GPU Clock 1350, Memory Clock 1900, mV -6

-asm 0 slowed me down
-asm 1 no change
Trying -asm 2 now

One thing I noticed is temps dropped from 73 to 67

Please advise...  I am not mining with CPU, only GPU

Benzo, 1120 on which clock?  Mem or GPU?

One more strange question for anyone out there.  I've tweaked my OC settings (I have 4 identical Sapphire 470 nitro 4GB) 3 are now running 300-305 H/s and GPU3 is running 205-220 H/s.  I am at a loss why this one is so much slower???

Any help is appreciated.

same problem on some of my ring, also happen with eth 6x 470 running at 27.x mh and gpu 3 running at 24 
but mostly the same with 5x 470 has not problem
also one 1 of my 380's ring there it s gpu 2 what is slower

Hello, Your GPU are NITRO or NITRO+ version??

I had the same problem one GPU Drops H/s, but when I turn off and disconnected PSU for a while, then turn on PSU, the problem was solved. (I tried reinstall all driver and not work, only turn off and turn on PSU was solved).

anyone can help... what is the meaning by gpu voltage +38mV?

last time i was flash my 290 to 390 rom..successed but unfortunately seems like not stable....please help

That means the GPU voltage will be 38 mV higher.

Hey guys!
I'm just wondering how big PSU recommended for 6x 390 rig (little OC maybe)? 1800-2000W?
I want to run custom bios and achieve 400+ sol / card

i'm running the r9 fury with 250 watts a piece for 470 hashes each.

If you're buying brand new get RX480 and you can get away with a 1000/1200 watts PSU running 7 for the same hashrate (330*7 rx=2410 ....  400*6 R9= 2400). I think the 390x will run at around 225 a piece so you may need at a minimum 1600 watts and be careful with the 15 amps breaker. Even if the the breaker is 20 amps be careful with the wires on the wall as they may melt.

price wise you will have a better deal with with rx480 ($1400 versus $2400) for the same end result. If you wait another month for the rx580 release they will be even cheaper.

Remember mining is foremost about economics.

Thanks. I can get the cards way cheaper than in shops. $190 each 390
But my next rig will be 480's

The R9 390x will run about 410H/s.

It is about the same speed as the R9 390.

Just wondering what the performance difference between a 4GB and an 8GB is on the Radeon RX480?

I have a number of sapphire RX480 8GB and they hash around 300

I bought 1 Asus Dual X to try out also 8GB but it is crap@ 280 hash

Looking to try a 4GB RX480 from Gigabyte - any ideas ?

I got a PowerColor RX480 8GB, going to add that to my HD7950. Not sure if I can get 300 sol/s with it though.

You need the newer driver for the RX 480 and old driver for 7950.

When is the new version coming out. The euterium outcrops slowed down our zec in mine.

I have:
2 Asus RX480 4GB ------> 275-280 H/s,
2 Gigabyte RX480 4GB --> 280-285 H/s.

Look at config.txt or pool.txt may be it cannot conect to dwarf somehow and trying failover pools ?

that's incorrect. 7950 and rx480 work fine with latest driver.
