[ANN][GRS] Groestlcoin | 1st to activate Segwit & Taproot

[Firebird2000]

Is there a better miner software for GPU mining than the one on the download page?
I seem to be having problems with this version of SGminer.
I have 2 PCs, each with 2 HD7950s in them.

For some reason on each, after about 5 minutes of mining, one GPU on each stops accepting shares and then the miner restarts itself.


This keeps happening over and over.
(I think CGwatcher sees it as a sick GPU)

Thanks!

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

in ur .bat
+
and check what kernel ur using in conf - make sure its groestlcoin

hope this helps

I have those in my .bat.
Also my config looks like this:

{
"pools" : [
        {
                "url" : "stratum+tcp://grs.cpu-pool.net:3650",
                "user" : "Firebird2000.Rig1",
                "pass" : "1"
        }
]
,
"intensity" : "20",
"kernel" : "groestlcoin",
"lookup-gap" : "2",
"thread-concurrency" : "21712",
"gpu-threads" : "1",
"gpu-engine" : "1150",
"auto-fan" : true,
"auto-gpu" : true,
"gpu-fan" : "30-85",
"gpu-memclock" : "1500",
"gpu-powertune" : "20",
"temp-overheat" : "80",
"temp-cutoff" : "85"
}


I seems to work great for about 5 minutes.
Then 1 gpu hashrate starts dropping right off.
The other stays perfect. This is happening on both of my machines.
Just can't figure out why.

Thanks.

try this

{
"pools" : [
        {
                "url" : "stratum+tcp://grs.cpu-pool.net:3650",
                "user" : "Firebird2000.Rig1",
                "pass" : "1"
        }
]
,
"intensity" : "20, 20",
"kernel" : "groestlcoin",
"lookup-gap" : "2",
"thread-concurrency" : "21712, 21712",
"gpu-threads" : "1, 1",
"gpu-engine" : "1150, 1150",
"auto-fan" : true,
"auto-gpu" : true,
"gpu-fan" : "30-85, 30-85",
"gpu-memclock" : "1500, 1500",
"gpu-powertune" : "20, 20",
"temp-overheat" : "80, 80",
"temp-cutoff" : "85, 85"
}

and dont forget

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

in ur .bat


if still not working try thread-concurrency of 8192

and pls change to a different pool - too much hashrate there

hope this helps

OK. Im gonna try this and see if it works.

Thanks!

Nope. No luck. Still the same....

[btc-mike]

According to http://cpucoinlist.com/ GPU advantage for GRS is 4.9. Does that match with current CPU miner on Haswell? If not - can someone contact maintainer of the list and get that corrected?

bump

I pulled all the numbers from settings spreadsheet. The calculations are on the bottom of this page.

I usually use the AMD-FX8320 as reference CPU because I have one. In this case, I used FX8350 because it was on the sheet.

Is there a new miner that makes the calcs incorrect?

I know we can do better than that. How about using an Intel chip, see http://www.groestlcoin.org/pools/ for some benchmarks. Any use?
also our list has been sorely neglected and requires updating.

Can u guys chime in pls and give btc-mike what he needs to place our higher in this ranking which clearly it deserves!

thanks all

I use r9 280x and FX-8320 as reference. I then make the GPU Advantage calculation like this:

GPU Advantage = GPU Hash Rate / CPU Hash Rate

In GroestlCoin's case, I used a better CPU's hash rate because it was easy at the time. I will run the miner on my machine this afternoon to get the actual hash rate for the AMD FX-8320 using yvg1900's yam M7r. I will also write a how-to.

You totally rock man!

Allrighty then. I retested on my CPU. After setting up huge pages and fine tuning, the hash rate on my CPU is 1340kh/s. That's lower than the FX8350 number used in the previous GPU Advantage calc so the GPU Advantage rose slightly.

I have reorganized my list based on market cap (previously it was GPU Advantage) so Groestlcoin is much closer to the top.

Why are yo overclocking your memory???
Downclock memory, you'll save lots of power trading for 1-2% drop in hashrate... and will get more stability.
What are temps of your cards (with GPU-Z, it should report seceral different temps, for GPU/Ram/voltage regulator)

To admins:

PLease remove CoinopenD from list of exchanges.
This is a known blackhole, a scam exchange!

Great tutorial

Which version of yam did u use for testing FX-8320 (bdver1) and is this properly optimized for the FX-8320? I see the FX-8320 is compared in some bencmarks to an i7-3770K. Multi-thread benchmarks show the cpus performing similarly, albeit the Intel faster.

I would expect a better result for the FX-8320 - will PM yvg1900 re this.

Fellow Groestlcoiners,

For your delectation, a heads-up for the new logo and paper wallet. Personally I think it looks sophisticated,
as if a Swiss Bank or venerated European financial institution had commissioned the designs.

I know some of us are attached to our scrabble tile, but perhaps that was always destined to be a placeholder for something else. We do not know gruve_p's intention here.

As valued members of the community we present you the designs before making an official announcement.

Speak now, or forever hold your peace
with respect,

CH

Yes, bdver1. I will reboot and let run overnight to verify.

hi, what is the block reward structure like for this coin? has it already decreased at all? and is there a bamt that can mine this?

[child_harold]

hi, what is the block reward structure like for this coin? has it already decreased at all? and is there a bamt that can mine this?

I decided to share my BAMT setup for GRS mining. For those, who don't know, BAMT is a very simle plug'n'play Linux distribution which is tailored to do only one thing: mine Scrypt coins. It also boots from 4GB+ flash drive, so you don't need to do any setup, just boot and mine. See https://litecointalk.org/index.php?topic=2924.0

Somehow, I could not get my R9 290 to perform as good in Windows 7. I tried 13.11 and 13.12 drivers. It could only achieve 8.5MHS. With BAMT I go as far as 9.8MHS.


Tested on BAMT 1.3 with Sapphire R9 290 TriX and Gigabyte R9 270X.
Here are the steps:

0. Download precompiled sph-sgminer from https://mega.co.nz/#!5F5kFLAR!tTDIYnsIL4NyBhe4A7nK63S9FREhCkmkSpsih64pIRM.
1. Bamt control \ stop mining sessions.
2. Accessories \ File Manager, browse to /opt/miners/ folder.
3. Rename existing "cgminer" folder to cgminerscrypt.
4. Copy contents of my ZIP file to "cgminer" folder.
5. Step inside the cgminer folder, locate "cgminer" file, right click it.
6. Switch to "Permissions" tab and turn on "Make the file executable".
7. Now go to /etc/bamt/ folder.
8. Backup your existing cgminer.conf to cgminerscrypt.conf.
9. Make cgminer.conf similar to something like this (Use recommended settings for your card, see https://docs.google.com/spreadsheet/ccc?key=0Atmcd1XbwbURdFVhT0w5RXdvcUdKdXVQVUt1blZZSHc#gid=0, this config is for "R9 270X, R9 290, R9 290"):
{
"pools" : [
   {
      "url" : "stratum+tcp://erebor.dwarfpool.com:3345",
      "user" : "YourWalletHere",
      "pass" : "p"
   },
   {
      "url" : "stratum+tcp://grs.cpu-pool.net:3650",
      "user" : "YourLogin",
      "pass" : "YourPass"
   },
   {
      "url" : "192.168.1.7:1441",
      "user" : "u",
      "pass" : "p"
   }
],

"gpu-engine" : "1225,1205,1205",
"gpu-memclock" : "1075,150,150",
"xintensity" : "512",
"thread-concurrency" : "21568,32767,32767",
"gpu-threads" : "1",

"auto-fan" : true,
"temp-cutoff" : "85,95,95",
"temp-overheat" : "80,90,90",
"temp-target" : "72,80,80",
"gpu-fan" : "25-80",
"worksize" : "256",

"api-port" : "4028",
"kernel" : "groestlcoin",
"gpu-powertune" : "20",
"scan-time": "1",
"expiry" : "5",
"queue" : "16"
}

10. Finally, do Bamt control \ start mining sessions.

Note: sph-sgminer webpage https://bitcointalk.org/index.php?topic=475795.0 recommends 4 threads, but somehow this results in dropping hash rate in approx 10 minutes. This happens only in Linux, in Windows it's all ok with 4 threads. So if you have similar problems, try 1 thread.


PS: Use the lowest possible RAM frequency (which is 150Mhz for my R9 290 and 1075 for my R9 270X), high memory frequencies are not needed for GROESTL.

awesome, thank you.

block reward structure? i don't see it in the OP

nevermind i see it now, 6% reduction about each week

I'm new to the forum but I just want to say that I am getting +2600 on a i7-4770K @ 3.50GHz (8 threads and stock/no OC). The numbers are about the same with both YAM M7q and YAM M7t (win64-Hawell eds.).

Done. I will add some more CPU's I have, but the whole list really should be updated after yvg1900's YAM releases. Such differences when comparing to other cpu miners
