To the best of my knowledge these syncing issues should have been resolved with new wallet releases. Please re-download your wallets before attempting to edit conf files. Latest wallets are here: http://www.groestlcoin.org/downloads/cheers! nb I've been using new wallet without any of these issues. GroestlCoin.conf rpcuser=username rpcpassword=password rpcallowip=127.0.0.1 rpcport=1441 port=1331 gen=0 server=1 addnode=37.187.129.122 … can't get it to sync, nodes?
68.0.160.3 70.123.187.172 … THANKS

Using PIMP (BAMT successor) and chose groestl as profile. Hashes are fine, but i dont get any shares..... Anyone any idea?

make sire your running latest version of sph-sgminer. Download here: https://bitcointalk.org/index.php?topic=475795.0If problem persists consult the FAQ on official website: 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

As agreed with btc-mike and yvg1900 I originaly posted this in btc-mike's CPU Coin List topic. I have copied you here as it will be of much interest to some of you. I will keep you appraised of any developments in btc-mike's thread, Enjoy! CH CPU Coin List https://bitcointalk.org/index.php?topic=483976.msg6528344#msg6528344Hello All, Following a disappointing result when btc-mike tested the latest YAM miner on an AMD FX-8320 hashing groestlcoin (1300Khs), and being a firm believer that Grøstl is the ultimate PoW I forwarded these results to yvg1900, the YAM miner dev. yvg1900 said he'd take a closer look at the findings. Earlier on today yvg1900 replied with some comments in a PM to me. Being very correct and diligent yvg1900 suggested I should confer with btc-mike before re-publishing the comments in a public forum. I agreed and notified btc-mike of our wish to make public these comments, seeking his approval in doing so. Of course btc-mike being a sound chap was quite happy to continue the dialogue and requested I publish yvg1900's thoughts in this thread. I agreed and he agreed I'd re-pot this in the Groestlcoin thread: https://bitcointalk.org/index.php?topic=525926.0So here follows yvg1900's comments after the results of btc-mike's test of an AMD FX-8320 hashing groestlcoin… Enjoy! thanks btc-mike and yvg1900 - you both totally røck! CH I took at deeper look on cpucoinlist situation, and here are some conclusions: 1). Yet AMD FX-8320 is not the low end one, it is definitely not the latest and most efficient CPU. It has been released back in October, 2012, but CPU technology advanced a lot since that time with introduction of AVX2 instruction set and Intel Haswell microarchitecture. GPU used for comparison was released one year later, and this heriod is a huge leap in modern data processing technology. 2). In my optimizations I target latest CPUs with lates features, and clear lead at the moment is Intel with their Haswell microarchitecture. AMD FX-8320 is not primary target for optimization, it actually benefits from optimizations targeted to Intel Sandy/Ivy Bridge CPUs (they are limited to AVX as well). I would suggest comparing AMD r9 280X GPU against Intel Xeon E3-1270v3 or i7 4770k CPUs, which have similar (or even significantly lower) price [hash pre $ invested] (I don't mind power consumption) [hash per watt]. 3) Newer Haswell Refresh CPUs are coming (or came) in $300 price range, that will bring even more performance boost to CPU mining. 4). When using yam miner it is very important to ensure that memory subsystem on the testing platform is configured correct way (i.e. if HugePages enabled and working). This may lead to nearly 2x performance difference on some coins (especially affected are MemoryCoin, ProtoShares and NoirShares; GroestlCoin is not affected so much). 5) CPU/GPU comparison table tinks to outdated version - makes sense to take a look at https://docs.google.com/spreadsheets/d/1hTOUdJZrKqrNDXTIbXgNvJtj_fnpECREcs-eHxaGrZc/edit#gid=256771159 instead (available in the OP at GRS ANN thread at botcointalk) 6) Now, just for comparison: from that table and other tests it is clear that Haswell CPUs do well over 2600 KH/s, and some single-CPU machines go over 2800 KH/s. There is a clear technical explanation for this: FX-8320 uses AVX, and Haswell CPUs use AVX2, which has 2x data width (256-bit registers) compared to AVX (128-bit registers). Thanks, yvg1900 Developer of yam miner

For testing, I turned the GPUs and some other background stuff off, and got as high as 2918kh/s from my i7-4770K (stock) with latest YAM. Thats of course awesome but it did make the computer completely non-resposive. Usually I dont run it -t 8 because of that, but its a powerful miner indeed ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

What is a "fake hash"? Have you been getting "share below target" messages? Should now be fixed. Please double check.

We also need pool operators to patch this exploit - it has been known for at least a year... https://litecointalk.org/index.php?topic=4002.0Legit miners should get out of that pool. On the bright side - one of the two fake miner is donating to the pool I believe that my pool is patched against this exploit. At least I don't see any suspicious miners and actual number of blocks is approximately equal to calculated. This used to be 3.7X more when I contacted OCMiner about the exploit. If you are worried - try mining on NOMP pool (groestlcoin.biz), it is using a brand new stratum which doesn't have this problem.

At least I don't see any suspicious miners and actual number of blocks is approximately equal to calculated. This used to be 3.7X more when I contacted OCMiner about the exploit. If you are worried - try mining on NOMP pool (groestlcoin.biz), it is using a brand new stratum which doesn't have this problem. It is kind of easy to check. The top two guys each have about 15% of the hashrate of your pool. They should find 15% of the blocks. Over the last 20 blocks, they found 6 blocks and 3 blocks respectively. 6/20 = 30%, 3/20 = 15%. It matches, therefore, they seem legit. Yes, I do this check all the time. But what if high hashers are legit and some minor miners are sending fake shares? Or if somebody has 2 rigs sending normal shares and 5 rigs sending fake shares? In such case it'll just look as very unlucky miner. So this worries me a bit. Does anyone know where to get this "fake share" miner code to verify that it doesn't work with our pools? If you are on MPOS pool, then you can check "blocks statistics" and it'll show you some info like this: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi.snag.gy%2FdgFTh.jpg&t=665&c=7GQmfC3HYdIQzg) As you can see, it is 5% above expected value. That's ok, I believe fluctuations like that a normal. But I'll make sure to keep an eye on this to make sure it does not grow. For reference, the compromised pool had 200% all time average and 370% 7 day average.

Read the OP - page 1 I did. In fact I have a rate slower then 6mhs they wrote, So, there is any that want to share the bat or conf file related to a 7950 and a r9 280x?
