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

[golden0707]

Hello and thank for your work,

I have two rigs with claymore v6, 385+h/s each = 770 H/s
DevFee 2.5 then average hashrate must be 770x0.95 = 750 but 6h average on pools is about 706 H/s

We are loosing 5% in devefee process or in some place. (v.6 shows 0 rejected on both rigs, great job!!)

Similar with claymore v5 and other pools (tried zcash nicehash and nanopool)
Maybe you can fix or it.
Thank you

Same here. Got two rigs with ~850 sol/s rate . But on nanopool its reporting ~780 within 12 hrs. And that was noticed long ago. Dont know why is that. Any ideas ?

0 reject.

BR.

yeah something is def up with the reported hash rates

Well, anyone who cares.... worked for 24+ hr. on flypool , from actual 720 sol/s from rig - minus devfee (2.5%) =  702 sol/s . That is real close to what i see on site ( 685 sol/s)

Fix the config file
one per line and not all in the same line

I didn't realize that the software allows remote upload of the configuration file in the default configuration... Ouch.
I have set the port to read only and changed it to a different number.

It may be a good idea to advise users in the next version of the readme file that such an exploit exists...

Thanks,

Ok, I'll add a warning in next update, in both readme and miner itself.

The majority of people will never use it and since it doesn't have any type of authentication, isn't it better to have it turned off by default?

[arielbit]

maybe it would be better if claymore release two versions of the miner..

1.  best hash per watt ratio for efficiency

2. the best hash a card can get, without considering the power consumption

some people have cheap electricity, they can benefit from no. 2...the other miners would benefit from no. 1

Hi there, after returning from zcash to eth I get "OpenCL error -4 (0) - cannot create DAG on GPU" for all 2G gpus - restart, power off - nothing helps - any idea someone?

[PandaPanda!]

@Claymore, could you please make some adjustments to your ethmon monitoring software?

Since moving to zec mining, the only units i've been able to use is KH/s and MH/s.  While this may not seem like a bad thing, there is a problem.  Let me explain.

When one of my GPUs crashes and is mining at 0H/s, the rest of the rig is still running.  The problem is that when I set my target hash rate, it doesn't warn me if i've lost a GPU because of the units used.  

Could you add an H/s unit to the software, so that it can warn me if theres a 50H+ difference in the rig's total hash rate?

Thanks

hi guys

can someone help me with my new RX480 8GB..

Screen of whattman configuration? for stable overclocking

Thanks

[stanis_r]

witch intensity do you use for RX 480 8GB mod-ed with 1500 Hz timing for 2080 Hz VRAM ?

[idonothave]

linux version?

[Hotmetal]

linux version?

1st page: There are builds for Windows x64 only. No Linux. No 32-bit support. No NVidia support.

[breakrules]

I have removed my ether strapped bios from my cards since Claymore 5 release as I will tune my cards when I no more what best settings will be,with each new release cards are under more stress and I believe using ether mods will not be best for zcash mining,I am getting 159 to 164H/s with my 480 8G nitros  and same with my xfx 480 8G GTR but the xfx run  cooler in same conditions,xfx are just great with cooling,all have Samsung memory and -60 core with 1340 clocks memory 2100 I believe power usage will be around same as what ether is when cards are maxed out and miner is optimised

Hi
Can you post what is your settings in .bat or config.txt TNX

[denis1995]

Please with the new version change also the name of thethread with (Only Windows)  because 70% of the post are "where to doenload the linux version"

And if you can with your next version to boost again the hashrate with the same power will be awesome.
Thanks.

Hi guys,

the last 2 days was looking for optimal settings for R9 390/290 for max hash rate...  Is it possible or is this the max i can get?

Thanx in advanced for any recommendation...

Im mining with:

PC ---- mb: MSI Z97 G55 / CPU: i7 4790K  / 12GB Kingston hyperX1600 Mhz ram  / Win 7 pro 64bit

3x MSI R9 390 gaming 8 GB

each getting 179-184 MH/s stable, no problems

RX480 strapped & with 1350 -> 1400 clocks working pretty solid for me.

You might want to add what motherboard/cpu/ram/os your using.

The 290/x's speed varies a lot depending on RAM type. Some mine at 145/s and some +170/s. Yet these same cards mine ETH at identical speeds.

[citronick]

6xR9 380 periodically resets GPU0 speed, and the miner errors appear non-existent cards, with which it can be connected?

It's a bug, will be fixed in next update. Divide card number by 2.

How soon will be next update ?

Do you want more speed?

The R9 Nanos uses HBM - high bandwidth memory - and have the best improvement vs all my other types of cards.

v6 has tremendously taken advantage of this features in R9 series that the card posting nearly 200 H/s even better past 180s H/s of 390s.

RX480s however at best posting 130-140s H/s -- could you do your magic on the RX cards?

My rx 480s doing  ~165H/s with v6

130 H/s is too low for an rx 480

These are 5 x RX480's .. They way past the 140 mark.. (zero gpu errors)
