Beginners Guide to Mining GroestlCoin with AMD cards and SPH-SGMiner

[child_harold]

I have prepared a PDF guide, shortly to be uploaded to site server.
In the meantime you can get it here:

Hi!

This seems to me that you have a too old / too new AMD driver.

Perhaps try BAMT?

ALso, sgminer has its official support forum. I definitely have seen the duplicate "const" error there.

I'd recommend that you check here: https://bitcointalk.org/index.php?topic=475795.0

[jackielove4u]

hi,

what catalyst version did u install? Can u post ur config here.

Try this:
1. Reinstall/upgrade/downgrade to catalyst 13.12
2. After catalyst upgrade, run sudo aticonfig --adapter=all --initial -f and reboot
3. Check that aticonfig detects card properly, and reinstall AMD-APP-SDK 2.9
4. Re-compile sph-sgminer

Otherwise try BAMT or Windows 8.1 (i can have a look with teamviewer if needed).

[Semedisenape]

Thanks guys.
After that I have read I think that you are right.

I'm on Xubuntu 12.04 with ADM 11.11 that was OK for scrypt mining and keccak,
but too old for groestl.

Now I try to update to 13.9. Do you think 13.12 are better?
I've got HD 5970 and 2x5870.

[jackielove4u]

I recommend using 13.12, it is considered more stable.

[Semedisenape]

[SOLVED] My problem was the driver.
With 14.4 and amd app sdk 2.9 everything works fine.

Once question. My cpu with sph-sgminer works more than cgminer.
Can I make something for it?

[child_harold]

I dont think you can reduce cpu footprint of sph - maybe someone knows better…

I have prepared a PDF guide, shortly to be uploaded to site server.
In the meantime you can get it here:
https://mega.co.nz/#!AFxziaoR!TyIyMn34EI3b7Gu2_hHQqkqH4CjWcygHQbGN99Yq8hU

Great pdf!

Some suggestions:
i would insert these into the bat:
--difficulty-multiplier 0.00390625

and i would remove this one:
--lookupgap 2

Optional:
setx GPU_MAX_HEAP_SIZE 50
--no-submit-stale (depens of pool)
--failover-only -o stratum+tcp://pool:port -u username.workername -p password (always setup a backup server)

Hi there!

For some reason, I am not able to push R9 280x pass 6.4 MHash/s mark. I am using the following miner:

https://github.com/badman74/sph-sgminer

I am not able to use your suggested miner as it does not submit any shares at dwarfpool.com. The machine hashes and hashes - AND EVEN IF I MINE with your miner and your suggested settings, I cannot push it over 6.3 MHash/s mark.

The card is in good shape, I have always able to push it when mining Scrypt. GPU clock is set to 1100, mem clock is set to 1500.

Settings I use, are:
    "auto-fan" : true,
    "gpu-fan": "30-99",
    "temp-cutoff" : "95",
    "temp-overheat" : "85",
    "temp-target" : "79",
    "worksize": "256",
    "intensity" : "20",
    "gpu-threads" : "1",
    "thread-concurrency" : "8192",
    "lookup-gap" : "0",
    "vectors" : "1",
    "shaders" : "2048",
    "api-port": "4028",
    "api-listen": true,
    "api-allow": "W:127.0.0.1",
    "failover-only" : true,
    "no-pool-disable": true,
    "no-submit-stale" : true,
    "queue": "0",
    "log" : "5",
    "gpu-powertune" : "20",
    "algorithm" : "groestlcoin",


Iam using BAMT 1.6.0 and I have compiled miners from scratch without any problems. The card is not overheating and I have a good PSU.

And very similar -  HD 5850 was cited to hash at 6 MHash/s speeds. Once again - I cannot push it over 5.4 MHash/s mark.

Core speed is 850, mem speed is 1000. Once again - platform BAMT 1.6.0, good quality card and a PSU.

[Copied from my btctalk answer to same Q]

1.If u are experiencing difficulty running suggested/latest miner pls try this tip from the official FAQ:
http://www.groestlcoin.org/faq/

My AMD GPU is hashing, but no shares are accepted and I don't see my hashrate on the pool. What's wrong?
Try adding

--difficulty-multiplier 0.0039062500

parameter to your sgminer command line. If your sgminer reports unrecognized option – please update to the recent version from here If this doesn’t help – report the problem in bitcointalk thread

Apologies for not including this tip in the tutorial. Will update pdf soon.


2. What core-clock speed r  u running? Have you used TrixX or AFterburner to overclock core and underclock mem as described in the pdf?

thanks

Hi there!

For some reason, I am not able to push R9 280x pass 6.4 MHash/s mark. I am using the following miner:

https://github.com/badman74/sph-sgminer

I am not able to use your suggested miner as it does not submit any shares at dwarfpool.com. The machine hashes and hashes - AND EVEN IF I MINE with your miner and your suggested settings, I cannot push it over 6.3 MHash/s mark.

The card is in good shape, I have always able to push it when mining Scrypt. GPU clock is set to 1100, mem clock is set to 1500.

Settings I use, are:
    "auto-fan" : true,
    "gpu-fan": "30-99",
    "temp-cutoff" : "95",
    "temp-overheat" : "85",
    "temp-target" : "79",
    "worksize": "256",
    "intensity" : "20",
    "gpu-threads" : "1",
    "thread-concurrency" : "8192",
    "lookup-gap" : "0",
    "vectors" : "1",
    "shaders" : "2048",
    "api-port": "4028",
    "api-listen": true,
    "api-allow": "W:127.0.0.1",
    "failover-only" : true,
    "no-pool-disable": true,
    "no-submit-stale" : true,
    "queue": "0",
    "log" : "5",
    "gpu-powertune" : "20",
    "algorithm" : "groestlcoin",


Iam using BAMT 1.6.0 and I have compiled miners from scratch without any problems. The card is not overheating and I have a good PSU.

It seems that only AMD drivers could be the problem, albeit I am running 13.25 drivers already. I'd like to recompile drivers with 13.xx latest drivers. But no 13.25 (or other stable drivers) are available from AMDs site. Only 14.40 drivers are avail<ble, but people are reporting loosing hashes instead of gaining them...

So, where are latest 13.xx drivers?
