Thanks for such transparency. Will we be able to withdraw other cryptocoins soon?

Before it does I manage to accept a few shared at 2.5 Mh/s Using elbereth' settings on R9 290 Any ideas? try basic settings to see if it will run first then try to optimize sgminer -k darkcoin -I 18 -g 2 -w 256 -o stratum+tcp://pool.darkcoin.io:3333 -u username -p x Ok that works and I get stable 2.2 Mh/s, thanks! Shame though its not that profitable, just did the math and its ~ 0.002 btc / day at current rates. Still will keep an eye on the coin, looks interesting.

Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN][YAC] Yacminer GPU miner for Yacoin

Hey, So I have bene playing with Yacminer and I can't pass the 1 kh/s without getting HW errors on my Sapphire R9 290. I was wondering, could I use ultracoin minier to mine yacoins? It uses scrypt-jane and I get on it stable 333 kh/s. But I get rejects when connection to a pool. Thirtybird, any thoughts on that? Is there a difference in the source? http://www.ultracoin.net/ultracoinminer.html Guy

Ok interesting, first I forced the gpu-engine and gpu-memclock to the standard on my card, and they seem to be holding. Now what was left was playing with the thread-concurrency. I got two results. First, could either set it to 32765. And then I got around 1.5hk/s. Which is not fun. Second, I tried pushing it up to 35960, but then something completely different happens! Hashing speed jumps up to around 40, but I ALL submissions are rejected with this error: Code: Rejected 7e3395cb Diff 2/2 GPU 0 (Share is above target) Here are my settings (thread concurrency varies according to story above) The good news is: no HW errors, just rejects now. Code: "thread-concurrency" : "35960", "api-listen" : true , "g": "2", "w" : "512", "gpu-fan" : "0-66", "gpu-memclock" : "1250", "gpu-engine" : "947", "intensity" : "10", "scrypt" : true Any thoughts why all the rejects? BTW no need to use GPU-z, linux here, reports are pretty accurate from yacminer

Thirtybird and other developers, could it be there is something in the miner that lets it work with only some cards? or the SDK needs updating? Guy The highest intensity I have been able to go has been 9 - and that still generates some HW errors. Low hash rates are to be expected, you just need to figure out which settings are best for your card. If you buy me an R9 290, I'll send you the best configuration for it Ok had a better look, it seems like the memory speed is forced to 150Mhz (can get up to 1500Mhz). I can go as high as intensity 10 without errors.

You can't build an ASIC (application specific integrated circuit) for scrypt. The scrypt algorithm was built to be memory intensive. That means you need hardware that has a lot of fast memory. What's special about that is that there is no "application specific" implementation for memory. That is, dedicated hardware for memory is, well, memory. So you can't build an ASIC for it. You could build a striped down equivalent of a graphic card for scrypt. But it won't be a massive jump like like it was with bitcoin's sha256, it might just be a little more cheaper and perhaps power consumption optimized. Not a game-changer.
