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

[Vann]

The blockchain drivers work fine. The latest drivers should also work fine.

[adaseb]

Anybody ever had any luck getting old Cayman (6950, 6970) cards to work with this?

I tried under Ubuntu 16.04 and ran into an OpenCL wall, the AMD drivers only work up to 14.04 and the open source drivers don't support the older cards.

I tried under Win7 and the cards got hot, but just returned incorrect data to the pool.

They work but you will get like 5 H/S

Mine XMR with those dinosaur GPUs. You can also mine any dagger coins if you got 2GB of memory.

I just spotted this "Claymores BTG Miner v12.6" https://github.com/poolgold/ClaymoreBTGMiner/releases . I've been doing some test mining of Bitcoin Gold with Claymore's ZCash miner and it work OK, so what is different with Claymores Bitcoin Gold miner compared to the ZCash miner ?

I've got two rigs of RX 570's, 1200/1900, blockchain driver.

The majority of GPUs hash close to 300sol/s, but some do only 60, and one or two are stuck at 20.

Is there any rationale behind this? If so, what am I supposed to do to get the dodgy ones to hash at decent speed??

EDIT: ah, ignore this. I just reduced intensity by one notch on the slow cards and this solved that. All peachy.

Why I can't get -cclock 1000,1050,1100,0 works?

It looks like the same zcash miner, renamed.

I'm only seeing one GPU temperature display on the console running v12.6.  Any ideas on how to get the 2nd GPU temp displayed?  Mining has been running good, just I never see GPU1 temp.

Running 2 RX470's on Windows.

E:\mining\zecMiner\ZecMiner64.exe -zpool ssl://us1-zcash.flypool.org:3443 -zwal t1xxxxxx  -zpsw x -i 8 -allpools 1

here's the log which matches the console - showing only GPU1s GPU0's
12:15:19:472   42fc   parse packet: 22
12:15:19:474   42fc   ZEC: Share accepted (109 ms)!

12:15:43:531   3710   watchdog - thread 1, hb time 93

I'm getting the temp displayed on Afterburner, so the driver/card is able to supply the data...

thanks

Not only on Suprnova but the pool I've tried, https://pool.miningspeed.com/ has ZERO Bitcoin Gold miners, I think other pools are also having problems.
I think the problem is more severe than just a pool problem, looks like the whole network is kaput !

Here is what MiningSpeed say about it..
"Bitcoingold is currently currently premining till block 499407, after this block our stratum will boot and start mining, no ETA on this, hang on!"

btgpool.pro displays a similar message:
"Attention! Pool is currently waiting for BTG developers pre-mine ending and will be up shortly! Blockchain Height current value: 497066 / 499407 (2341 blocks left)"

Just sit and wait till the pre-mine is finished, I guess.

Is there a Claymore ZCash miner for Nvidia??

[alisafidel58]

I always get this problem whenever i start to mine, been trying different pools but i still get the same error can anybody tell me how to fix this.
I dont know what "OpenCL error" this is my first time mining.

[jankekek]

Does anyone here know how to get past the opencl error 0 #101 issues? I'm running a pair of older 6970s, and with every version so far I've had these errors pop up, one for each gpu. Then the miner proceeds to sit there and do nothing at all, or BSOD my system.

[andersh]

Is the hash rate reported on the command line accurate or do I need to wait to see what the pool says after (say) 30 mins? I'm tweaking my settings and overclocking, but I'm not sure what to trust.

Hello,
I have a problem mining with AMD Vega 64 on Windows 10 PRO (RX580 Works fine)

[rambetiko]

Does anyone use single rx vega 64? what are the hashrate values? how to blockchain driver for btg mining? I once tried to see 450 sol/s with blockchain driver (hbm2 1085 mhz, gpu -10%) worth less?

The trust should hashrate which shows the miner. Pool can display hashrate different from that of the miner in larger or smaller at different times.
The main thing is the number of received shares.

Having trouble getting this up and running for AMD. I'm a newbie to mining so I'm probably doing something very simple and dumb.
I don't want to spam this threads with questions, but if anyone is available to PM me so I can bounce some questions off you, I would SUPER appreciate it. Thanks much and good luck to everyone mining.

I'm looking at your Video Card.... and I see it has 887 mb vram and 2 compute units.. Dude
you can't even use that to mine with... Get a AMD RX 480 or the new VEGA cards.
