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

Hello! Sorry for offtopic question , but what is the advantage of using powered risers ? I was using 1x-1x unpowered risers with H61 BTC PRO ( wich has 2x MOLEX power plugs) for 2 yr. and had no problem with it.

The Current series of graphics cards, the RX 470/480 pull almost 1/3rd of their power from the PCIe slot directly so unpowered risers would either not work or simply burn out. Older cards work fine with unpowered risers though, since they draw almost all of their power from the PSU power cable.

If you use that H61 board, there is no need for the powered riser.

Wewisk,deadsix Thank you

Thinking to install powered risers instead of unpowered, now Im not so sure. May be its good enough to use unpowered risers with Zcash mining , coz its less power hugry then ETH mining.....

So good ETH is high, finally all 480s are there:)

That is right. The 480 is much more efficient to mine Ethereum. 7970/280x is more efficient to mine ZCash.

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).

find the ideal settings for each card individually, test it crash proof for at least 24h.

then put it in a rig along side other cards, maintaining space for proper cooling. ensure cooling is sufficient to surpass the environmental conditions during your 24h test scenario.

if you still crash it's likely a software issue like drivers or windows trickery.

if you are crashing or hanging while running the card individually for testing ideal configuration:

increase voltage which increases heat but makes things stable at higher clocks
decrease voltage which decreases heat but makes things unstable at higher than factory clocks due to sensitivity to quality of power signal delivered by gpu
decrease intensity which makes the card run cooler and cuts the workload slightly
decrease the clocks, gpu vs memory depend on the quality of your cooling solutions
clean and repaste your GPU

i do believe most of this has been said before..

Thanks for the tips.  I pulled the suspect card from the rig and running another one of same kind for awhile to see if it is specific with this card.  i think the card might be bad :-/

Rig ran all night stable with suspect card gone.  Briefly put bad card directly on mobo and still problems.  Guess the card is indeed bad.  Fried mother board all risers and two vid cards in the adventures this weekend lol.  Good news is found great deal on XFX Radeon RX480 on newegg ($180 after rebate) so have 4 new cards on the way.

If you use the 480/470, it is better to mine the ETH.

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??

I wonder why my Sapphiry Fury Nitro show 0 sols with asm algo. Anyone experienced this?

You need to reduce the intensity to -i 6 or lower.

That does not help. Tried even intensity 1. With - asm 0 I get 400 sols.

With this card, i only tried (-asm 1) and i get 430+ sols, using 15.12 drivers.
Quick guess, double check your driver version, as Windows loves to forcefully update the driver.

I think the problem is with the driver.

driver 15.12, -i 6, win7 64bit here, getting 470H/s with overclock

Hi Could you please show the capture of the overclock params for the fury

i think it is getting ~460+ H/s using optiminer

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.

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.

If you do not stress your graphics cards, Clayjmore runs smoothly.
