CGminer Help with CryptoCoinMine

[jimbo]

paint-
ok according to your cap viewer post you have a 512 mb card. which would make your work size 512 i know that much but that wont get you up and running..

i gave up on it when i realized theres a cuda miner for my nvidia card that works more efficient than cgminer.  i suppose anyhow. older nvidia cards suck anyway. and i dont want to stop mining to try it again lol

i was totally lost also with all the technological stuff that dream had posted, but makes me hungry to find out.

come on dream.. in walk us through it some. 

i would like to try cgminer for my cpu instead of my wallet but cant get it to work either.i ive pretty much got the same problem and im to small time to know exactly what im talking about so im lost there. but it HAS TO run in scrypt or wont work. i know too know, that much!

If you need a good CPU miner use ScryptMiner GUI, I use it in place of running the wallet all the time.

Here's a link for it.   https://bitcointalk.org/index.php?topic=62414.0

I use 8 Threads and my Scantime is 99 . I get +- 30 Kh/s with these setting. My CPU has 10 cores so I set it on 8 the highest setting it has. It leave 2 cores for other stuff on the PC. I don't do much on it, so I just let it run most of the time almost 24/7.  I also found out, if I mine a different coin. I can sell it and buy more GLD than I can mine at the 30 Kh/s ... Well most of the time, depends on the price and with GLD being around .001 I might be about even.

hey thanks alot bill. you know its funny you said that cuz it just stuck me earier. mine other "junk" coins and trade for gold (well not junk exactly,but im for goldcoin so its kinda junk to me)lol  any idea on a good valued junk coin lol (there i go again..) thats easily mined so i can have my laptops mine it slowly but surly?? paint i think your on to somthing here

i got a cheap $85 AMD phenom II  x4 965 black edition (4 core) so i think you got me beat

[ipaint]

I just downloaded the updated cgMiner. I added "kernel" : "scrypt", and it kind of worked lol .. It didn't crash anyway.

So using the "kernel" : "scrypt",  I get the error

"LOOKUP_GAP" is undefined
const unit ySIZE = <1024/LOOKUP_GAP+<1024%LOOKUP_GAP>0>>;

I have "lookup-gap" : "2", in the conf file. I also tried 1 and "0" and I still get the same error. Any ideas what I should do?

[jimbo]

ok sorry bout this i was reading the scrypt readme file that came with cgminer 3.3.1 windows32 and it was saying NOT to underclock your memory and we did exactly that..  so.. lol use your caps veiwer and find your max clock: mem speed . for starters.  read that readme file that came with the cgminer download it says something about lookup gap and thread concurrency.

[ipaint]

I've been reading the README file. I've been playing with different settings and I still get the same error message. I don't know what the error means 1024/LOOKUPGAP etc.

A few more pointers:

Do not be concerned about GPU/Memory speeds at this point. Just leave those clock settings at "0" (Card default) until you get CGminer running smooth.

Intensity should be set at around 13 (for scrypt coins like Goldcoin, SHA 256 coins normally get set at around 5) to start, again this can be tweaked later. Using a negative number slows the miner down. If you are mining on a computer that you also use for other things, set intensity to "d". Cgminer will adjust the intensity dynamically to allow other applications fair share at resources.

Lookup-gap set at 2 is normal.

Worksize should only be either 64,128 or 256. It has NOTHING to do with the amount of memory your GPU has. This setting is more about the GPU chip and memory interface (not size). Some GPU work better with information in less but larger chunks of information while others work better with more smaller chunks of information.

Do not worry about thread-concurrency at this point. Set it at zero, we are going to have CGmine calculate the concurrency by setting shaders.

Shaders need to be set at how many shaders your GPU has. One needs to find this information.

For the scrypt readme in Cgminer:

Code: [Select]

GPU Shaders
7750 512
7770 640
7850 1024
7870 1280
7950 1792
7970 2048

6850 960
6870 1120
6950 1408
6970 1536
6990 (6970x2)

6570 480
6670 480
6790 800

6450 160

5670 400
5750 720
5770 800
5830 1120
5850 1440
5870 1600
5970 (5870x2)
A good place to see how others have set up their hardware:

http://litecoin.info/Mining_Hardware_Comparison

Mining any scrypt coin is the same (with a couple of exceptions), so these examples apply to Goldcoin as well.

[ipaint]

I'm about ready to give up ... Now there's something wrong with the CONCURRENT_THREADS size

I also added the cg.sh file

[dreamwatcher]

After doing a bit of research on mining with the 7560D, I found some parameters that work for one person, but many others cannot get that model of GPU to mine correctly.

I have made up a cgminer.conf file for you, just change user and password field to match yours:

Code: [Select]

{
"pools" : [

        {
                "url" : "stratum+tcp://gld.cryptocoinmine.com:2020",
                "user" : "username",
                "pass" : "password"
        }
]
,
"intensity" : "13",
"vectors" : "2",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"thread-concurrency" : "1024",
"shaders" : "0",
"gpu-engine" : "0",
"gpu-fan" : "0-85",
"gpu-memclock" : "0",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

Now, I set the concurrency at 1024 to start (256 shaders * 4). The GENERAL rule of thumb is AMD 5000 series use  shaders * 5, AMD series 6000 and up use shaders * 4. Since in the configuration we are using concurrency there is no need to set shaders. Shaders is only used by Cgminer to try and guess the concurrency when none is given.

In the article I found the person was using concurrency at 2048. However he was using the  Litecoin daemon mining interface with mining software that was not Cgminer.  I have never heard of anybody using shaders * 8 with Cgminer.

Also remember that the JSON format of the conf file has to be exact, CgMiner(and JSON in general) is extremely strict about its formatting rules. Just cut and paste exactly what I have posted with the exception of username and password.

If this does not work, do not worry, the 7560 is not a stellar performer anyhow, and you will probably spend more on electricity then you would make with mined coins. I do understand your desire to support Goldcoin and hope it does work for you.

Otherwise, I would suggest picking a good used 5800 or 6900 series GPU.I have seen some 5850 go as cheap as $50.00 on ebay. My rig#3 consists of two 5850 and with almost no tweaking at all (Have not had the time) I am getting around 300 KH/s on each.

That-a-boy dream,good man

so what do you think about those ASIC block erupters? are they only for bitcoin or SHA coins?? wouldnt they be a better investment for the speed and electricity usage??? or are they disposable compared to a gpu at over $200?

thank you


*Hope this works for ya paint

[ipaint]

Thanks dream, But of course with my luck it didn't work    For some strange reason I just can't get it to run when I add scrypt.

I did mine PPcoin just to see if it was working and it did. But not wroth mining at 56 Mh/s. I noticed all of the SHA coins have a high Diff. or I'd mine one of them for BTC.

Thanks for your help everyone, but this plan is D.O.A.

[ipaint]

Just so you all know I did get this working. Only problem is. It starts off at about 160 Kh/s then very slowly it drops down to about 20 Kh/s or less. No idea why but it works just not worth mining with seeing it has less Kh/s than my CPUs.

Hey All.
 New to GoldCoin. But I have been mining LTC for a while. I have worked out the best setting for CGMiner with 7950's. So I am going to post the .conf file. So with these setting I am getting 690KH/s. Hope this helps the network to perform better.
