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

[hobbyminer67]

Hey All,

I'm trying the new AMD drivers on my 7 rx 470 rig, all stock settings, but one of the GPU's keeps giving the below error

GPU #0 returned incorrect data! 5015fcc9

All others seem to be fine, this gpu still manages to get some shares though.

I have changed the intensity too for this GPU but made no difference

Any ideas?

Hi, I had similar issue with my 5 x 280x rig, would eventually hang, finally had to do,  i 5,4,2,5,4 to get all errors to clear, all run +/-295 except 2, +/-285

Claymore, have you tried out the new drivers for GPU mining from AMD? Do you have any recommendations?

These drivers must work better for Vega, though I was not able to install them for Vega FE. For Polaris I don't see any changes in speed for ZEC.

Hello Claymore, I found another guy with the DRM error :

Maybe it's time to fix it  

Unfortunately, I have no idea what you mean, I don't have enough experience in these Linux problems. I test my miners on ubuntu 16.04 and gpu-pro drivers, for old cards I use 15.12 drivers and Ubuntu 12.04, for NVidia I use Ubuntu 14.04 with CUDA8-compatible drivers, it works fine. Since you did not specify any details, may be you use some different Linux or drivers. My miners are for Windows mainly, I compile them for Linux because of a lot of users requests, I don't test all Linux builds and drivers because it can take forever.

Sorry, I will give you more info.
I lack experience with theses new drivers too but I think I could help you troubleshoot it. Moreover, I think it is an issue you will have to fix in the future if it's on Claymore side (could be some change they made on amdpu that requires intervention from user side, no idea...)

So I use the free amdgpu driver and amd-staging-4.12 kernel. I will check if I have the same issue with linux-mainline (the linux 4.12 you find in your usual distros).
I didn't have this issue with amd-mainline-hybrid-4.11 kernel.
So my guess it that they changed some code between amd-mainline-hybrid-4.11 and amd-staging-4.12 kernels and that it will be merged sooner or later in the linux mainline kernel and in the gpu-pro driver.

Here's the AMD kernels I'm talking about : https://cgit.freedesktop.org/~agd5f/linux/
Thanks for the linux support by the way
 
Edit :
No issue on linux-mainline either, so I guess the code has not been merged there either.
So the issue only happen on amd-staging-4.11 and amd-staging-4.12 kernels which are the kernels/drivers where the code is first merged so people can use it before it finally lands in linux-mainline (which can take quite some time).

Hi Claymore, VEGA it's good.
But when we can see optimization for gddr5x memory? or 37 mh/s for eth on 1080ti it's maximum?

Don't ask about ETH in the Zcash thread. Ask in the Claymore dual miner thread.

I don't think there is a lot of room for ETH mining on a 1080ti. It is significantly more profitable to mine equihash Zcash/ZCL/HUSH on a 1080ti card.  Only a fool would mine ETH with a 1080ti.

You're losing something like $1.10 per day, per GPU if you mine ETH on a 1080 ti.  If you research it a little bit you'll find a 1080ti isn't the right card for mining ETH. You'd be better off buying 2x as many 1070s. They're half the price and do ~30 MH ETH.

Claymore, cannot run v 12.6 on ubuntu 12.04.5

Code:

fermer@ferma1:~/Desktop/Claymore's ZCash AMD GPU Miner v12.6 - LINUX$ ./zecminer64
./zecminr64: relocation error: ./zecminer64: symbol _ZNSt7_cxx1112basic_strngIcSt11char_traisIcESaIcEEC1EPKcRKS3_, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

Both ETH9.8 and ZEC12.5 work just fine.
Should be easy to fix - rebuilding with an older libc should help

Hello,

I have scoured the internet for an issue that I am having before coming on here.  I have an issue with Claymore crashing due to these following:

Cannot get Overdrive capabilites for adapter 24 (error -1)

They follow a long lisst of adapter #from 0 to 30..  No one seems to have an answer for this.

Thanks

Yes, I had to use Ubuntu 16.04 for compiling v12.6 because GCC from Ubuntu 12.04 has some bugs and cannot compile my code correctly, I spent half a day until I found that the problem is not in my code but in old GCC.

Is there a way to fix it ?
Which gcc version did you use ?
May be it works in 14.04 ?
I have a bunch of old fglrx cards that won't work on windows anymore and it gets harder and harder to support them on linux.

[rascabily]

why all time error with gpu 0  in version claymore 12.6?
all me rigs stop few minut.

now i'm just having 125H/S with my rx 460

Does anyone have new numbers with the RX 560? Curious how that compares to the 1050(ti)

Is that fast or not?

[Ursul0]

Any improvement for AMD RX470, or is there no need to upgrade?

I think hashrate improvements for polaris stopped somewhere around v11 of the miner
the stability of various versions may depend on your cards and setup. for instance I was having stability issues with all versions above 12.2 on my mixed rig with 4*470 and a single 370 in slot. however it seems to be very stable with 12.6 now...
I've tried "amd blochckain" driver and didn't particularly like the fan speeds I was getting, so I'm back to 16.11.4

I doubt it can go any higher than 37MH/s.

Hey all,

I am trying to tweak my rig, but struggling with baseline settings. I have searched the web and read through forums for answers, but all the answers seem to be ethereum, or all the zcash posts are way old

Does anyone know what is a good base hashrate for Sapphire RX470 Nitro+ 8GB and Sapphire RX470 Nitro 8GB, on stock ROM

I can get the RX470 Nitro+ running at about 270-275 Sol/s, and the RX470 running around 255-260 Sol/s, 7 cards total running just over 1000w

But no idea on what is actually any good.

Any help would be great.

154h for my 560 gpu at 1300mhz
148h for 460 with unlock shader gpu 1210mhz
143 for 460 with locked shaders  1200mhz

Hi,

just for comparison:

3 Rigs with windows 7/8.1 64 bit  Claymore 12.6

6 * 7790  86 H/s each
4 * 7850 145 H/s each
1 * 7850 135 H/s
2 * R9 270 160 H/s each

Have a nice day

P.S: The speed is shown at the pool ( 2% Fee and invalid/stale shares are already substracted)

[peteycamey]

any plans for 12.7 ? no performance increase for a long time.

I do not think 12.7 will have any performance increase.

[wirelessnet2]

I have a bunch of R9 Nanos. Do I still have to stick to the old 15.12 drivers for ASM to work properly? Or do the new [Suspicious link removed]pute drivers work fine
