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

[Claymore]

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

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?

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

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

https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-[Suspicious link removed]pute-Release-Notes.aspx

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.

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?

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

[PB_SilentMiner]

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

DevFee: stop mining and disconnect

EDIT:  this hour DevFee found nine shares in 49 seconds, this represents a rate more than four times that of the non-DevFee share rate.

this version is not working at all. I add the correct information and it will not start

It's a good idea to read Readme.txt or first post of this thread carefully.

12.6 is waste of time, no increase performance, rather decrease of hashrates and crashes.
12.5 still the best

From the FAQ section of the first post:

Q: Why do I see more shares for devfee than in my mining for the same time?
A: Most pools support variable diff, they change "target share" after some time after connection. For example, you have very powerful rig, after connection you will send shares very often. It takes some CPU time to check your shares so after some time pool will send higher share target and miner will send less shares (but they will have more value). When pool updates share target you will see "Pool sets new share target" line in the miner. This way pool can adjust the number of shares that miner sends and balance its load.
So check the log or console text to see current target for main mining thread and for devfee thread. For example:
DevFee: Pool sets new share target: 0x0083126e (diff: 500H) - this is for devfee mining connection
Pool sets new share target: 0x0024fa4f (diff: 1772H) - this is for main mining connection
As you can see, target share for main mining is higher in about 3.5 times, so for main mining miner sends in 3 times less shares (but they have 3x more value) than for devfee mining.

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)

my rx 460 is unlocked so it's the same as an RX 560
