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

I have two R9 270 (not x) in a Linux 14.04 box with the 15.12 drivers. Using 12.3.  I am getting 172 H/s for each card.
Make sure you set the environment variables as stated in the readme (see script below).
When the zecminer64 starts it reduces the intensity to 4.

bash script:
#!/bin/bash   
export GPU_FORCE_64BIT_PTR=1
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100

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.

good post

i mix and match quite a bit and even have risers from when the first came out (never the ribbons tho)

first always check the riser and power supplies, that sata connection is dead important not to have too much load on a single line

if claymores software encounters an issue then it will be in the logs.... start with one card and test over 12/24 hrs, adding one more card at a time, might also be good to clean up drivers and reg entries using DDU

was having a few windows issues recently as well, tried loads of things to fix it and to my surprise all it needed was a rollback using system restore settings, perfect after 3/4 hrs reinstalling and testing lol

[majorlee]

odd request maybe

i got hold of a HD7990 by powercolour, its a huge card and runs quite 'slow' @ 935/1350 on both chips

its the black model

does anyone have new bios to get better performance out of this?

[snakey]

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.

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

Claymore please, we need your attention here!

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.

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.

Might grab a few extra 470s while I can get them at these low prices...Worst case I just buy a few new cards to add onto the miner.

Thanks bardacuda and claymore.

[koody]

I will test the new version, ty Claymore.

i have my 80gb HDDs cloned, any HDD issue I encounter, I just unplug the problematic HDD and plug a clone.

the problematic HDD will go through a file system test and bad sector test (results will determine if it will be reused or trashed), if windows is unstable due to corruption of files etc..it will be overwritten by a clone...my HDDs clone each other, as long as the good HDD is always the source.

my last windows 7 64bit installation for my mining rigs was in 2013..cloning saves time and utilizes a proven windows setup. 

always have extra risers, PSUs, HDDs, RAMs etc...having identical motherboards in your rigs is a plus too.

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.

Thanks -i 3 worked. now get 290 h/s on GPU 0,1.  try before -i 4 or 5 having problems

Is that 290 h/s for one card?

290 is for one core of the card. A 7990 does ~600 H/s.

I had a similar issue with the 7990, to keep it worked I had to reduce intensity, I was using win 7, but it disappeared when I switched to win 10.

It seems that the 7990 is much better than the RX 470 or 480.

It's also at least 3x the cost and probably 2x the power usage lol.

awesome mining advice!

back in 2012/13 i was using USB and Linuxs, no HDD's what-so-ever!

quick tip if miners wanna save some cash on spare HDD's, find people giving away old sky+ boxes or any media items that can record and play TV, they all have a HDD in them u can plug out!

anyone else have this issue?

Claymore can u tell me more about this?

I occasionally get a random card telling me that same thing "returned incorrect data!" in red text.  It's only ever a single line/return of that.  Nothing bad seems to result and mining continues as normal (as far as I can tell).

it does not seem to effect my hashrate

but recently been getting these sometimes on one GPU in a rig, the first lines are coloured red, and red means stop usually lol, so can anyone tell me?

Code:

15:36:28:040	bf8	GPU #3 returned incorrect data! 20ee04
15:36:29:696	1c0	GPU #3 returned incorrect data! 29afa1

When I get that, I will reduce the clock frequency, then it will disappear.
