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

[shadabahmed]

Hi, Could Somenne help with this?

One R9 280x Drops hashrate from 285 to 150 after some time shows this "WATCHDOG: GPU 1 hanges in OpenCL call, exit" and miners restart.

put monitor cable on that 280 card.
i was faced same problem last month and with this method my problem solved

I wonder if a dummy plug would work in that situation??

maybe it will work i diidnt try this.

Hey guys, would appreciate an honest answer here please.

I was about to buy a few RX 470 8GB cards to mine either zcash or ETH but have been hearing about these new cards about to be released....Will there be a massive difference in speed from the 470/480s compared to these new cards?

I dont want to build a rig that gets me 1800 - 2100H/s then get blown away by a new miner with new cards that gets double + speeds..

I remember claymore mentioning that he cant do much because of the following..

Memory bandwidth:

RX480: 256 GB/s

If these new cards have the same bandwidth then does that mean no real big speed improvement?

Thanks.

Hello,

I have 2 Nano,  1 R9 280x and 1 RX480, is there a driver version where i can mix them and use -asm 1 for all cards?

if i use 15.12 i can not use RX480
if i use 16.12.2 i can not user nano with -asm 1

Thank you

No. Either split cards to different rigs, or use Linux version (but amd-pro drivers don't support 280x).

And what about 2 directories?
Driver 16.12.2
The first directory with miner for 480 and 280
The second directory with the necessary OpenCL libraries from previous drivers for the nano
will it work?

Would like to know more about it too, maybe Claymore can explain this to us.

Claymore please, we need your attention here!

bought a new desktop rig, not for dedicated mining purposes, just because I've come into some fat stacks, yo, Jesse.

Decided to go for a good value/on special Gigabyte 1060 6G, I run it along side my old GTX 960.

HOWEVER - a few days earlier I was browsing around and came across an Asus Strix RX 470 - I was running a Sapphire Nitro+ RX480 4GB card along side the GTX960. So - new rig - 2x nvidia. Old rig RX480/new RX470.

The RX470 cost me $190NZD - I'd just like to share with you how fkn impressed I am with its performance - pulling in consistent 260-290 Sol/s giving a total of 560 Sol/s+ with only minor Wattman alterations (stock BIOS's).

Moral of the story is - if you're not retarded and can undervolt/overclock and maintain consistency then $190 for the RX470 was a fkn steal.

Claymore says:
This miner is free-to-use, however, current developer fee is 2% if you use secure SSL/TLS connection to mining pool, every hour the miner mines for 72 seconds for developer.
If you use unsecure connection to mining pool, current developer fee is 2.5%, every hour the miner mines for 90 seconds for developer.

So if you're using suprnova pool, I'd use ssl://zec.suprnova.cc:2242

I cannot comment unreleased cards. Changes in hardware can improve or kill speed on such complex PoW as ZEC, there is no way to know until real tests.

Good Morning people.
I have a problem with Claymore, He starts work is fine, but later he crash and freezing all the Rig. Install windows again, download a new version of Claymore and stay the same.

Need help.

claymore miner issue fixes:
 
  - read the "readme.txt" for other settings
  - make sure you are using the right drivers
  - watch and play with your overclocks
  - look at your "-i" options, make sure your intensity is not too high

other issues: (getting into GPU mining has a prerequisite which is you should know how to troubleshoot OS and PC hardware) -> i believe this is not claymore's problem anymore

 - riser issues
 - PSU issues
 - motherboard issues
 - GPU issues
 - HDD issues
 - RAM issues
 - temperature issues

yesterday one of my rig freezes and windows crashed after mining started for a few seconds...it was a HDD bad sector issue.. find the source of problem, you can do it.

Thanks my friend. I believe my rig is stable, 12 hours stable. I was change the line command in .bat

Thank for you answer.

rx580  300H/S already test
rx5xx almost as fast as rx4xx

You wish.  RX 580 delayed until mid April at least.

Like the price on the 580 at under $200

hey guys, how can I report to the development team?
I have a XFX HD7990 video card. are working perfect in Claymore's Zcash AMD GPU Miner V11.1 (Windows 10 64bit), It gets speed about 259 h/s on GPU 0 and 1, total about 520 h/s. But in the GPU miner V12 are all not working on my video car, GPU 0 get 0 h/s and GPU 1  less 100 h/s. I have been change the different radeon drive V15, V16, V17 still not working.

MY another 2 video card HD7950 are working perfect in GPU miner V12 and get 280 h/s in over core clock 1100mhz.

please help my HD7990 fly up in V12

thanks,

I have working 7990 (=600s/s) with stock on 12.3 with -i 3. Driver 15.12. In case you modded memory try to return to original bios.

You need to reduce the intensity to 5 or 4.

[IOTUSA]

What's the deal with 11+ dropping random cards to 0 hash now and then? Is there a known fix. Lower intensity doesn't do it.

Maybe the new miner stresses the card more. You need to reduce the clock frequency to tr.

[uscoin1]

That's some crazy speed.  wish i had some good GPUs to play with. 

electricity can now be paid for after the zec price increase.  how much is the price of gpus now compare to few months ago.
we'll i just saw it's 30% cheaper.

The new Vega cards are supposed to have half the memory bus width but a higher speed (2048-bit @ 1600MHz effective vs. 4096-bit @ 1000MHz effective) than Fury X, but with the same 4096 compute cores (although probably at a higher clock and lower power draw with perhaps some architectural improvements too).

I believe Claymore said that the 4096-bit bus width of Fury is too wide to be taken advantage of, but the 512-bit bus of Hawaii can be fully taken advantage of...so worst case scenario (Fury is bottlenecked by its compute performance) it should perform at least a little better than Fury X. Best-case (Fury is bottlenecked by its memory) I would assume as much as 60% faster than Fury just considering the memory frequency increase alone but this is just speculation on my part.

hello.

i am buying a rig.

what is better for mining  zcash regarding ROi:

rx 470 4 GB  preice per card: 215 €
rx 470 8 gb                         220 €
rx 480 4 gb                        220€
rx 480 8 gb                       260 €

i will try to put up to 6 gpus per rig. if any one have 7, is system stabile?

any recomendation for motherboard? h81 pro BTC for 6 gpu or any better, maybe for 7 gpus?

thanky  for help

You should really mine ETH and alike with polaris cards. I would get 480 8gb.
h81 pro btc are fine, not sure where are we with 7gpu rigs those days - think it needs win10 / linux

[cohnhead]

can anyone post a link for modding bios for a gigabyte hd 7950. (Hynix memory)
i'm getting about 500 sols with gpu settings at 900/1250 and using about 400 watts, thinking I could do alot better
running on a h81 pro btc windows 7

hi claymore

I'm using ubuntu 16.04 with and 16.60 driver
only get around 150h on an rx480 8g
try the different setting but no luck.
working fine on windows.

any idea?

Same OS and driver as me, but I have R9 270X and only getting 10h/s.  I think it's all down to needing the exact right OS and driver combo as per Claymore posts.  I think you have to use 15.10 and proprietary AMD driver (Ubuntu 16.40 uses new amdgpu-pro stack).  Can't get any of my other zcash miners to work at all on this set up.

I have rx480 , ubuntu 16.04, 16.60 drivers and doing 300 H/S on my card.  Maybe reinstall OS/drivers.  My 380x on same rig doing 193-200H/S.  Any problems I mentioned before had nothing to do with Claymore - all Hardware issues like bad risers.  Claymore makes a solid product.

Thx.  Have tried again and now getting ~66h/s with my 270x.
