Core i7-4670K gets about 410KHash/s on DRK while using around 77W
R9 290X gets about 2000KHash/s on DRK while using around 225W (?)

As phm wrote above, for some reason the GPUs are not at 100% power use right now, which is great for consumption really. CPU power is rarely close to the TDP, and for the i7-4670K it should be <70.

Many CPUs can significantly improve their consumption through undervolting at stock volt. When you have a cpu that can gain, say, +0.6 to +1 GHz with stock volt, then that's a great sign that it can go at stock speeds with far less power.

Generally speaking CPUs are far more flexible in increasing power efficiency through undervolting* than GPUs. If combined with more CPU acceleration in the future by accelerating further hashes there's room for co-existence because the vast ratio of scrypt or sha acceleration is not maintained in X11.

* For example my wolfdale celeron e3200 at 2.4GHz can run stock at 1.02v instead of 1.28v and 1.9GHz with just 0.9v with "core temps" being like 40c - nothing.

I'm finally building the windows binaries of the new CPU-miner. After that I'll try to improve the performances

.

For who said that GPU version is always better. Maybe this is the case, maybe it's not. It depends if and how much the code can be parallelized.
I'll try to see what CPU can achieve. And if it's not enough, I'll study the convenience to mix CPU and GPU, if I'll see that some algo cant be well parallelized on the GPU

So here's an interesting note:

Core i7-4670K gets about 410KHash/s on DRK while using around 77W
R9 290X gets about 2000KHash/s on DRK while using around 225W (?)

Clearly the GPU is faster and more efficient, but we're only looking at a different of about 40%. Unless someone can get a speedup out of the GPU miners to the point where it's more like 1000% more efficient, CPU mining should remain viable. Just my two cents. :-)

Sorry, but your assumptions are wrong. My 4 x R9 290 rig uses about 450W when idle and about 1450W when 100% busy mining scrypt coins. However when mining DRK it only uses 900W of power (so about 112W for each card) - due to the nature of calculations (lots of random memory access in 3 or 4 hash functions) full potential of GPU cores cannot be used and they use much less power. That means mining with GPU is over 300% more efficient.

Ok, but we have to compare with total wattage right?
4xR9 -> 900W/4= 225W, 2000khs/225 = 8.88 kh/sec for Watt
i7-4670k -> 77w, 410Khs/77 = 5.32 kh/sec for Watt

Surely then, it's easier a rig of GPUs than a rig of CPUs. But this for now it's a 30% improvement for Watt, depending on what CPUs and what GPUs.
So I want to see if there is a 30% margin to improve the cpu miner.

Let me know if you and the others think that I am wrong about something...

Yes, you are wrong again, because you didn't include total PC wattage in CPU calculations, just CPU wattage. I bet PC eats at least 200 W when running, so it would be 410Khs/200 = 2.05 kh/s per watt. Now CPU looks even worse.

May I ask, is it possible to tamper the sgminer files in some way to get some hashes running through the cpu instead of the gpu? Like hash1 done in gpu, hash2 done in gpu, hash 3 done in cpu, hash 4 done in gpu etc...

I don't really see the point of doing that. Just run a CPU miner alongside GPU miner.

Any recommendations for a CPU only coin to mine now?

Is there any CPU only coins?

+1

A few exist https://bitcointalksearch.org/topic/list-of-cpu-friendly-altcoins-379601

I was looking at Qubit on the list which has 5 hashes overlapping with DRK. Fastest cpu miners are developed by the same people that develop our DRK miner. This means that GPU acceleration is 100% possible in it by "downgrading" our sgminer and making it run the 5 hashes instead of 11. Some other cpu coins have overlapping hashes too which mean GPU acceleration for them too.

maybe phm help us to porting darkcoin gpuminer on qubitcoin gpuminer))
p.s. if i dont wrong, the same part hashes is in quarkcoin, sifcoin and others forks of this coins...

Ok, here the link for the Windows binaries -> https://mega.co.nz/#!pBZzQAII!yuvzhcnx3ezLre9fek_G67D0_IyiNqIbEHKY4cKdovA
Read the README for choose the right version for your processor.
Remember, only Windows 64 bit, and only for processors that supports at least AES-NI instructions.

P.S. I hate and I still hate compiling binaries on MinGW, I spent 2 days to set a working crosscompiling environment for this.
The problem was that new versions of build of MinGW64 have a gcc that is hard linked with a new pthread library, called libwinpthread, that it's not good for compiling this... thanks to ig0tik3d for pointing to me the working version of MinGW64...

Guys/Gals,
This what I get when I run the debug command for sgminer. Can anyone tell me what I can try to get sgminer working. I hate to keep asking rookie questions but I really like where this coin is going and besides, I guess this is how you learn.

Any feedback would be great. Thanks.

....

Hey. Error 11 is very broad but I see you are running a 5000 series Radeon card and most people had the same issue. I managed to fix it on a machine running a 5970 and another running two 5770s

The issue is mainly in your settings, primarily thread concurrency causing the display drivers to fail launching.

1. Use something like this for your .bat

Quote

sgminer --kernel darkcoin -o stratum+tcp://pool.darkcoin.io:3333 -u accountname.worker -p password -I 17 -g 2 -w 256 --lookup-gap 2 --thread-concurrency 3200

I've found on both types of 5xxx cards if I try bumping thread concurrency any higher you will get Error 11, same with turning down worksize. I'm working on a fix for this now but in the mean time that should do it.

2. If the above fails, get the latest Beta display driver (14.1) from AMD from their website (and use the same settings)

http://support.amd.com/en-us/download/desktop?os=Windows%207%20-%2064

---------------------------------------------------------------------------

That should get you up and running for now, it worked for 2 of my machines and a few others on this board. Let me know if you have any more problems.

I've tried changing the thread-concurrency to 3200 and tried adding the --no-adl and it still didn't work. I have the latest driver as well. Honestly though, I've tried so many different combinations of things now, I'm not sure if I tried those both in the same .bat file. I'll give it another go. Thanks for the response. I haven't created a .conf file yet but seems as if creating the right .bat file first should at least get me started. Once I settle on some settings, then I can create a .conf

Been fiddling with settings all day and still getting:

Code:

Error -11: Building Program (clBuildProgram)
Error compiling program for search.
Frontend phase failed compilation.
Error: Creating kernel search failed!
Failed to init GPU thread 2, disabling device 2

I am using a config file. My GPUs are the following: ASUS 6990, HIS 5770 and driver version is 13.251.0.0

We need a good DRK/USD exchange in the near future. As Bitcoin's terrible volatility will lead darkcoin's growth into futility.

What's more, if you were to throw an R9 290X at DRK and get 2MHash/s, you'll generate roughly 0.02 BTC per day. If you throw the same GPU at something like VTC, you'll generate roughly 0.02 BTC per day. And currently mining MAX (whether you like the ideas behind the coin or not!), you can get around 0.02 BTC per day. If tons of people shift to GPU mining DRK, difficulty will go up, rewards will go down, and suddenly one of the other alt-coins will be more profitable. I suspect we're going to see some big fluctuations in difficulty in the near term on DRK as people jump on and off the bandwagon.

Want to get Darkcoin listed on cryptorush.in? They've contacted us and they require a fee for listing of 300DRK.

Please donate to get us listed! XxBh3RnSza7dftvMX2JZmNd6ipaTi7KGKx

Why would we pay them to be on their exchange?
There will be a time they beg us to be on their exchange Cool

I agree.

Have a look at the stats on c-cex:
https://c-cex.com/index.html?id=stat

Usually exchanges have a commission of 0.2% ~ 0.3%, so, that is the amount they will be earning if they decide to include DRK into their website.

I am currently using c-cex.com with excellent results. For me, this site has proven to work much better than other well known exchange sites. No need to pay for additional exchanges.

C-CEX thanks jesus everyday for the bright idea they had in accepting DRK. 70%+ of their exchange is based on it. Also holy sell orders @0.00068 already

Let the community decide if they want to pay to be on the exchange

I disagree with it personally

But if the donations reach the necessary amount, then that will naturally make the decision

I agree, leave it to the community to donate or not.

I for one say no to paying to be on an exchange. (like I actually have any say in anything Tongue

Not to mention that "deal" they offer shows they would list any pump and dump coin like that for the sake of devs cash. We don't need such PR due to DarkCoin's intristic value. I would rather insist on creation of wikipage/subreddit/forum/ect. so people could easier get to know about DRK.
