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.

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.

If there is specific hash where the cpu can excel and the GPU sucks then this would make more sense.

Any recommendations for a CPU only coin to mine now?

Is there any CPU only coins?

A few exist https://bitcointalk.org/index.php?topic=379601.0

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...

That's correct, it shall be easy to adapt the miner to QRK and its clones, all needed hash functions are already there. But I'm way too lazy to do it without additional motivation

All of you guys consider only operational costs. And they vary heavily depending on electricity cost. Though they also include rent (not many people are able to run them at home, I guess).

And what about initial costs of CPU and GPU mining rigs? What about probability of killing GPUs and CPUs by that heavy load? I heard that GPU's don't live long under these conditions.

[elmad]

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.

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.

Ok, do you measured 900W for the rig at the wall? Please, someone could mesaure a fast i7 or Xeon at the wall? Possibly a configuration without discrete GPU or other, just motherboard, cpu, disk? and ram.

P.S. I am just curious about this, I dont say that for sure it's in a way or in an other. I want to see if it's useful go to try to improve the cpu miner or not.

P.P.S. Someone that have a rent of Xeon instances can do the math Khs per $?

motivation i think you can found in topics of those coins))
p.s. i think cpuminer can be more optimized ...

Wallet not syncing:  I've had the Xcoin wallet v0.8.6.2 stuck at block 15199 for about 5 days now, and even though it's saying there are 5 network connections active, nothing's been updating since.  Is there a problem with the chain???  

Attempted stops & restarts, and it's still 5 days out-of-sync at the moment

I live there so I would love to swing by!!! Amazing work!

Well, roughly 3.5 Kh/$ (monthly cost). I believe it's possible to find a bit more efficient servers (like 4-4.5 Kh/$) but it needs evaluation.

I'm just making the technology. Me nor InternetApe support any illegal use of this technology (drug sites, darknet, etc). It's more about the privacy of the blockchain, it was made to be way too open and I can solve that.

It's kind of the same thing as us building and selling guns. Someone could buy one to defend their house or someone could buy it to do terrible things.

Play safe man.
Hope you are much more capable than darksend.

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

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

I just tried the latest beta display driver with no changes in my situation.

That did it - thanks!  Took me a moment to realize the old wallet.dat was still in the [%APPDAT%]/xcoin folder, but once I got that moved over, everything looks pretty again.

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

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...

If've got some problems...
It seem I don't have  the AES-NI.
I download the Intel Processor Identification Utility .
I 've got a Intel i7-2600 CPU@ 3.4Ghz
But in the TAB : CPU Technology I've got :
Intel AES new intructions  ----> No

Did mi processor din't support it or need new BIOS or something?
I'm working with win7 Home Premium

EDIT : in the intel page information about the precessor it's said that it can support.. will investigate with BIOS version and option...

EDIT2 : Yes, it was disable in the BIOS.
I enable it and use the : minerd-corei7-avx.exe

Yes it's much better:

I am in full agreement with you, just some other people might not be. Your public appearance may have implications for you that you quite simply have not thought of yet.

Plus, it is a lot cooler if the creator of "Darkcoin" be mysterious and unknown. Adds to the appeal! ;-)
