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

[LionOfNarnia]

Seems to be more probs at

https://grs.cryptohunger.com/index.php?page=dashboard

No mining atm, pool hashrate = zero

... and no notices at the pool either!

[Digithusiast]

same here, seems to be problems at cryptohunger for over 2hrs now...  

stats shows pool hash rate 0 and active members 0

the contact email form on the pool website does not work...

[LionOfNarnia]

I had a quick trip to coinium, it does appear to work (with a single worker at least), but just for now I'm multi-pooling for Btc on CashCows, there IS a good reason for such insanity, I promise 

I'll be back as soon as CryptoHunger is working OK again, don't wanna have to set up 5 new workers on a new pool on a Saturday night.

Could be just pure luck? Or maybe they have most of the hashrate?

Actually I looked at their stats, it looks quite normal..

Pool speed 8799.129 mhs (40-60% of the total network hashrate)

If this is true I think all miners would get an equal share,
I am mining GRS for days at grs.suprnova.cc and payout seems to be normal.

You could be right we need someone more experienced to check this.

this is a bug,someone use it to speed up the mining phase
today,block reward decreased 6%
if this bug not fixed,you will see another 6% tomorrow

Guys, I'm no expert in cryptography, but I sincerely doubt it's a 51% attack.
Other pools seem to work & get new blocks just fine. I think it's a specific problem with grs.cryptohunger.com.

Just shwitch to groestlcoin.biz, grs.coinmine.pl or grs.suprnova.cc.

Like child_harold said, srcxxxx will probably be awake in about 2h and sort everything out.

hello

and https://cpu-pool.net/grs/ looks solved the pool problem  i read pool news started the new pool v2.0 i mining 12 hours ago this pool and work fine.

bye

[beyonders]

hello

whats is your .bat for 280x on Dwarfpool ?

thx

[child_harold]

hello

whats is your .bat for 280x on Dwarfpool ?

thx

Something like:

setx GPU_MAX_ALLOC_PERCENT 100

setx GPU_USE_SYNC_OBJECTS 1

sgminer.exe --kernel groestlcoin -o stratum+tcp:// xxx.com:xxxx -u xxx.WORKERNAME -p WORKERPASSWORD --thread-concurrency 8192 -I 20 --lookup- gap 2 -- worksize 256 -g 1 --gpu-engine 1100 --gpu- memclock 1500 --gpu- powertune 20

Remember to use TrixX or Aftreburner to set/check clock speeds.

Or if u wanna go for a conf setup that bat/ conf combo looks like:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

sgminer.exe -c name-of-your.conf
