Anyone know what BTC can you get with 100 mh/s on ETH?

I'm not sure if everything worked with the open source ccminer so I won't assume anything.
Your OS is two years old and ccminer was compiled with the latest cuda 7.5, likely a compatibilty issue.
Check if cuda 7.5 and the supported drives are available for your version (X)Ubuntu. You don't need
cuda to run ccminer but you have to have drivers compatible with the cuda version used to build it.

If you can't get cuda 7.5 supported drivers for your OS you'll have to upgdade the os or ask SP to
build with 6.5.

What about a solution of multiple cards working together or in other words the DAG file being shared in chunks over all GPUs. Or is the bandwidth between cards would make it slower?

17 mhash is elpida

and the 22mhash is? (samsung I guess?)

btw what is the core clock AND memory clock set to?

I was wondering about the lower hash I was getting on W10, thanks for the info.

It's not a bug. It's an overlooked side-effect of randomly accessing huge memory areas. I'm still at a loss as to how the algo designers didn't see this coming. With DAG hitting 1280MB now, the first reports on specific types of AMD cards biting the dust on ETH are already coming in (Tahiti, notably).

antantti's donation of today has motivated me to start working on an optimisation for those cards. That optimisation is already part of my DAGger simulator and seems to work pretty well. I'm not entirely sure why this optimisation seems to negate the effects of TLB trashing, but I think it has something to do with the odd memory architecture of GCN 1.0.  

I was actually planning to sit back and watch the DAGpocalypse happening, but the last thing Ethereum can use now is miners leaving en masse.

actually, Bensam123 has been serving us for months the extended version of his ideas... we got it the first time, we gave our opinions, but still it is coming back in an even longer format day after day

(must admit, I am running out of good joke to make about it... )

Oh shit, i seriously pissed my pants reading that. I knew this was coming and it was already there before i could even think it. 

LOL! I think that was it! 

can I have the executive summary ?

When the market for Feather gets pushed up for 3-4 months, it's probably a good sign that miners will be mining it with Neoscrypt. As I mentioned before, just looking at whattomine would give you a pretty good idea of what's in demand. Some coins are not on What though like Ethereum (despite requesting it a few times) and Spread.

Now that Cryptsy crashed and Feathercoin is pretty much obliterated, there is no demand for Neoscrypt, which means almost no one will be looking to buy a miner for it. You can always market this as 'donations', but that's not what people want or need.

Making a product is a two way relationship. Both the maker and the user have to benefit. Just making something because you feel like it, then complaining when people don't donate doesn't help anyone. You need to eat, I need to eat, I mine whatever is most profitable, you help me make more profits, I help you eat too. It's not too complicated. Right now that's Ethereum and Spread. If x11 could be improved that definitely would be a bread winner too.

I'm all for a miner fee to support you guys long run too and just use whoevers miner is faster (or hopefully a combination miner that everyone can get paid from). In particular, this should hold a lot of interest for you as a developer. It means however much you improve a miner is how much you get paid and just having the fastest miner means you will make money off of it, regardless of how much faster it is then the competition (within reason). If it's just 2% faster then the competition, then a miner fee would be paid for. Claymore marketed his miner this way and it worked quite well.


I've read the thread (and keep up with SP's thread on a regular basis) about Ethereum and I realize there are development hurdles, that doesn't change that it's in demand and if someone figures out how to get around it with some sort of clever trick they'll reap rewards for it. Considering AMD hardware seems to max out at 30Mhs and Nvidia stuff about 30% less, there may be room for improvement to get around the whole memory controller exploding. Even if you can't do it, someone else may come along who might be able to by doing something you never thought of, so it needs to be talked about...

Currently we were talking about Ethminer not working as well in W8 compared to W10, which is a bug and it may or may not be able to be figured out, but we wont be able to tell until things are looked at more thoroughly.


Yup... I understand they can do what they want, but when it comes down to it and people need to profit, we need to talk about what really needs to be done. Right now SP's working on pretty much everything and I would like to buy his private miner, but nothing he's making is more profitable... It's a bad business decision for me. Maybe in the future when something he's making becomes more profitable then say Eth or Spread, I'll buy his miner.

I would love to either buy a miner or use a miner with a miner fee that earns me more money. Everyone profits! It's the best sort of business relationship. I'm sure there are plenty of big farms with their own employed kernel devs working on x11 even if they rather work on Lyra right now or something.

Because I don't think sp_ wants to sell his private kernel as source code. If I'm wrong about that I'd much prefer to compile it myself.

Ask jublo, he made it working. Wich ccminer exe file are you trying to run?

why do you even want to run it under wine... you have to compile it for linux... 

I'm having trouble getting ccminer.exe to run in WINE. I looked through the threads a bit after failing to get it to work. Seems there are mixed results out there.
get error
Card is GTX-750ti, OS Xubuntu 14.04, CUDA 7.5, nVidia driver 352.68. Pretty sure that's all up to date. What am I missing?

I am making miners for high demand algos.

I have 4 private miners for the people who donate.

1. 0.1BTC: Pentablake +100-120%
2. 0.1BTC: Cryptonight +10%
3. 0.1BTC: Spreadcoin +10-20%
4. 0.1BTC: All nicehash algos optimized. 0-7%  (x11 +2.4% (faster than release 74 ) on the 750ti)

Thanks a lot!

I agree on the part where devs modify whatever they feel like. In a way, it's their right to do so. If they want to make more money. yeah, they should mod whatever is most profitable. And there are out there that do so. But mostly not in public ;-)

And as stated above, in some cases, it just isn't worth the time/effort.

again with these too long message to edit...  

just to react a bit: there is no high demand algo, it is just a question of timing and you can't switch project in the middle of the project because of some p&d scheme going on at an instant t on some unknown coin.

Second, some of you (especially you in fact ) need to realize that hashrate can't be increased indefinitely. We know where it is possible (roughly) to get some improvement but for some algos it would be too much work (hence not profitable for us) to develop. For ethereum,  development is stuck by the size of the dag file and nothing can really be done about it, because it is way too large for most of the cards... the alternative would be to recalculate part of the dag element (actually I tried it...) but it is then too slow, because there are very large loop...)
So no matter how much you want a better eth miner, there are constraints which limit any kind of development at that level.

Most big miners run nix, this means farms. Most small miners are running Windows as it's easy to use and doesn't require a degree to fix.

I've not seen any stability issues in Windows in all the time I've spent mining. It will hash slower, but now days that seems negligible except for some weird niche cases (and sometimes it goes the opposite direction too).

Big miners get bigger because they have private kernel developers working for them and/or they have public private miners working for them (like Wolf0). With high entry fees to get a kernel, if they will sell it to you at all and you know they're selling it, most small miners are losing ground. This is why I pushed so much for a nice public miner with a fee. That's accessible to anyone, at any level, big or small.

This aside, its seems as though most developers that will work with the public community don't even want to make what the miners need, such as kernels for high demand algos. Right now for instance it's Eth, Spread, and X11 (if that can be brought up to speed). Eth especially right now is getting pushed hard. Miners don't get to choose what's profitable, that's up to the dice of the exchanges. No one can predict that.



Hmmm... I can go back to W8, I'd just rather not do it in case a issue pops up in the future. There is no way of fixing this? I don't know enough about TLB usage to offer productive input on that.

Speaking of memory hard algos. I just tried Monero on my 970 on both w8 and w10, they produced very similar hashrates. Based on what you're talking about, this bug should be present in Monero as well? This could also be because Cryptonote was never optimized on Nvidia GPUs, but I assume it would manifest itself in some way.
