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

[th00ber]

pardon me my stupd question but can I mine zclassic with this miner?

Indeed stupid ! (Joking )
A miner is good for an algo.
So every coin from this algo family will be ok
(Equihash is the algo of the Zcash).

Zcl will be ok

[joe50]

zcash will hit $1000 before year end

When I do -i 6 on my 7950's, it says there is not enough ram and it reduces it to 5! What SOL/s are you getting on your 7950s?

Well I have managed about 260 (-i 5) at 950/1450/1.05v, last claymore zec miner.

I'm getting around the same hashrate (-i 5) on my 7950's. I have not done the undervolting yet. Will it make a lot of difference to power/heat?

I have 2 rigs that every morning falls between 7,30 to 8,30, One is running ZCash with 3 R9-290x Driver 15.12 and the other one ETH-PASC 3 RX-580 Driver 17.4.4, both latest version of claymore, both W10 Pro version 1703 15063.
I am using teamviewer to connect with them
Has someone the same problem??

[slovakia]

what hashrate you have with Sapphire Radeon HD 7970 OC 3GB   
thanks

I'm trying to mine using the Claymore V12.5 program using an AMD HD5750 1GB DDR5 card in the Suprnova Pool, however the program returns the following error: "OpenCL error 0 # 101 - -61". My motherboard has 2 GB DDR3 and runs the Win7 64bit. The Catalyst (GPU Card Driver) installed is version 15.12 and SDK 3.0. What is wrong?

260-290H/s
Depending of the freq

I would love to get some help mining.  I mined years ago but it seems I have no idea what I'm doing anymore.  I have tried every miner available and it seems I get the same error.  I've tried different pools but alas no luck.
ZEC: Stratum - Cannot connect to eu1-zcash.flypool.
ZEC: Stratum - Failed to connect, retry in 20 sec..

I am running windows 7 64 bit,  r9 390, Catalyst 15.12.  My batch file contains:

GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100
ZecMiner64.exe -zpool eu1-zcash.flypool.org:3333 -zwal t1UKaEoMka8CghGrsehTKMXR72jZZMrpTKr.1 -zpsw x -i 8

I would appreciate any help.  I'm using the claymore miner v12.5 but I've gotten the same errors on other miners.  I'm probably missing something easy but thanks in advance.

Make sure your firewall is not blocking the connection of ZecMiner64.exe

Please i need to understand what make some GPU has more hashrates than others, from the following list of GPU features which exactly is the main responsible for better or high hashreates:

1. Core Clock(Mhz)
2. Memory Capacity
3. Stream Processors
4. Memory Speed
5. Memory Clock(Mhz)
6. Process:(xx nanometers)
7. PixelPipelines
8. Memory Interface: (128, 256 Bit or higher)

 HD 5750 is terrascale, not GCN - Claymore is written for GCN cards, though it *sometimes* works on some older pre-GCN cards there is no guarentee.

 However, I suspect part of your issue is you need more system RAM.

For Zcash I believe Memory bandwidth mainly
RX 480 256 GB/s
R9 390 384 GB/s

Secondly the Core Clock

The microprocessor gives energy perfomance.

Anyways someone can add more info..

So I'm having the same exact problem and your remedy didn't fix it... I'm on windows 10 64bit with an R9 Fury Nitro (Catalyst 17.1.1) and Claymore 12.5. My firewall allows claymore through. I'm using the configuration you recommended. My hash rate is zero. Any suggestions? Should I downgrade to the recommended Fiji drivers first?

that pretty much sums it up.. the memory STRAP comes in to play also but was not listed in original query.

Process (xx nanometers) is just the manufacturing specification.. the more advanced (lower number) processes may allow for higher core over clocks but generally it just means the chip is more energy efficient.

[QuintLeo]

ZEC is reliant on a lot more than just the memory bandwidth, otherwise the GTX 1070 would NOT be quite a bit faster than the RX 480/580 8GB cards (that have the SAME bus width and memory speed).

ETH on the other hand is VERY reliant on memory bandwidth AND low memory latency, which is why the old R9 290 is still one of the best ETH miner cards in existence despite having rather low clocks on memory and core (but has a very WIDE memory interface) - and it's also why the HBM based cards don't do anywhere near as well as their memory bandwidth says they should, HBM has high latency compared to GDDR.

 I dunno where "stream processors" is from - even AMD doesn't use the Stream interface any more since they got in behind and started pushing OpenCL.
 Perhaps that was supposed to be "cores" or "shaders"?


 Process is not directly a factor, though it's a major INdirect factor that affects power efficiency and clock rates and how many cores you can fit on a chip without overheating.
 Pixel pipelines do not matter at all.
 Memory capacity does not matter at all (except for ETH and spinoffs that use a DAG file, as the entire DAG file has to fit into the ram on the GPU so you need "just enough" more doesn't help).

Please could somebody help me work out how to get the most out of my R9 380s.

I used to mine ZEC using a GTX950 and got 165 sol/s. I then bought an R9 380 and with using the Claymore Zcash AMD GPU miner I got an extra 210 sol/s. I then bought a second R9 380 and swapped out the GTX950.
Initially I was getting 210 sol/s on each card but my mining pool report said I was hashing at 0 sol/s. I left it for a few hours and still nothing, despite the miner seeming to be working OK.

I restarted the miner and now I get 175 sol/s from one card and 20 sol/s from the other. I dont understand whats happening. Do I need to run two instances of the miner or change some settings? I have played with the intensity. I havent put it above 6 yet but if I lower the intensity the hash rate goes down.

Please help! I was hoping to mine at over 400 sol/s but at the moment i'm getting 200 sol/s from two R9 380s!

I think you need to use the 15.12 driver.

[DevaVictrix]

When I bought my first R9 380 I tried the 15.12 driver and it yielded the same as the most recent driver. I'll try it again and report back.

EDIT: Yup, for one card the driver version made no difference... for two, the 15.12 driver now gives 210sol/s on each card and reports temps and fan utilisation for both cards (it only did it for GPU 0 last time). I should have re-read the instructions!

Thank you!

Hi!

Well, I think there's no point in going into too much detail with this all configurations, as there are so many parameters and the values (the actual coin exchange, network hashrate, tdp and electricity costs, etc.) are so variable that is almost impossible to be accurate and useful... The best aproach, I think, is to resume the main cards into a table like this one:

Simple enough to understand, and quite realistic, don't you think?

[pehoko]

I think my 7950 mine better than RX 480.
