Cryptocoin Mining?

[hondaf17]

Well my first day of mining behind me. About 13 hours running with a 6950. Averaged about 400 kh/s. 2118 valid, 24 invalid (whatever that means). .0510 LTC balance. GPU runs stable at 75 degrees C. My electrical cost is $.065 / Kwh.

Does everything seem to check out OK???

TYIA,

Anyone getting this on wemineltc? Shutting down after a few mins, then this:

[2013-12-13 21:02:06] Stratum connection to pool 0 interrupted

Anyone know anything about Casino Coins (CSC)? Thinking of throwing one mining rig at it for giggles.

Yeah, I've seen it show up on the long list of Cryptocoins out there.

I still think that BBQCoin is my favorite of the obscure altcoins out there, since there are actually some BBQ joints that take it as payment

TYIA,

why does that seem like a very high return for 13 hours with a 6950?

 

[TerryMathews]

When I was playing around with mining I was pulling 400kh/s on a bone stock 6950.

Seems right to me.

If this advice hasn't been voiced yet. Avoid the most popular Pools. By enabling them with top hash-rates, they can team up and price-control LTC.

That would be wemineltc then?

Would they want prices to stay down or go up?

The problem is that a lot of the smaller pools aren't reliable, and can be down for days at a time. Some pools also seem to generate a lot of stale blocks for some reason.

Strange how my card works better using the stock 290's bios. When fully unlocked to 290x it gave worse results using the same settings.

Cgminer shows 762.0Kh's average. Going to try tweaking my script a little more to boost my output....No issues with current script with custom fan profile stays a tad under 90c with 60% max fan no throttle at stock clocks +20% power limit.

The 290x on left I was playing around with the script which does contribute to the fluctuations. I used the same script at the end and once I saw the Kh's output stayed as a unlocked 290.

I'm skeptical. The scrypt algorithm was specifically chosen to be ASIC-resistant; unlike SHA-256, it needs fast access to a decent amount of RAM (about 128K for each hash). So, unlike SHA-256...

I agree with JDG, I think ASIC level mining devices are a lot further away for the Scrypt flavor of coin than some people think. The last realistic timeframe I saw was about a year off, and I think it might be a bit more still than that based on things out there as of now. Unless things evolve quickly, you can probably say GPU mining will be viable for the coming year or so at least.

I've been using WeMineLTC as primary and Give-Me-Coins (previously Give-Me-LTC) as backup for several months, so I'll recommend Give-Me-Coins, especially as they are currently the third largest pool. Coinotron was unreliable for me in the past, so I won't recommend them.

I got it working as mentioned below. I had the same issue. When watching the task manager and starting the GUI miner, it would start the cgminer which would disappear in a few seconds (apparently crashing cgminer 3.5).



Ok, yeah I guess I'm using one of the ones in this page.
https://www.wemineltc.com/gettingstarted



Thanks. The guide is basically only useful for the litecoin wallet and pool setup.

I got it working with the latest catalyst beta driver (NO SDK) and cgminer 3.6.6. (https://github.com/kanoi/cgminer-binaries)

The SDK, driver, cgminer/guiminer suggested in the thread just wouldn't work for me.

Just start the cgminer with the cmd.

>cgminer.exe --scrypt -o stratum+tcp://world.wemineltc.com:3335 -u username.1 -p minepoolpassword -I 17

If you are just playing around with it and just getting setup, verify you are not getting Hardware errors!

It's on the line:
GPU 0: temp RPM | Kh/s | Accepted: Rejected: HardwareErrors WorkUnits Intensity

I had a ton of hardware errors which leads back to the drivers or SDK or CGMiner version. I still haven't resolved that.

 

[nwo]

It's not. 0.05 is actually lower than expected for 400kH/s. Should be 0.07 for 13 hours or roughly 0.14 per day.

So it would be the HW:0 mine shows. That would be no errors?

Just upped my intensity to 18 and churning at 795Kh/s had to up the fan profile to 62% max to compensate to keep under 90c on core. Just checked the vrm temps as I forgot about them. Seems fine at 71c 81c to me. The stock cooler is loud but keeps vrm's low enough for me.

Yeah HW:0 means there aren't any errors. :thumbsup:

Unfortunately I'm getting nearly as high (hardware errors) as Accepted or even higher depending on Intensity (on both GPUs). I suspect it's a software issue.

If you are getting HW errors, your intensity is too high for the -thread concurrency.
Lower intensity or increase -thread concurrency

--intensity XX

Just like in bitcoin mining, scrypt mining takes an intensity, however the
scale goes from 0 to 20 to mimic the "Aggression" used in mtrlt's reaper. The
reason this is crucial is that too high an intensity can actually be
disastrous with scrypt because it CAN run out of ram. Intensities over 13
start writing over the same ram and it is highly dependent on the GPU, but they
can start actually DECREASING your hashrate, or even worse, start producing
garbage with HW errors skyrocketing. The low level detail is that intensity is
only guaranteed up to the power of 2 that most closely matches the thread
concurrency. i.e. a thread concurrency of 6144 has 8192 as the nearest power
of two above it, thus as 2^13=8192, that is an intensity of 13.


--thread-concurrency:
This tunes the optimal size of work that scrypt can do. It is internally tuned
by cgminer to be the highest reasonable multiple of shaders that it can
allocate on your GPU. Ideally it should be a multiple of your shader count.
vliw5 architecture (R5XXX) would be best at 5x shaders, while VLIW4 (R6xxx and
R7xxx) are best at 4x. Setting thread concurrency overrides anything you put
into --shaders.

Now it finally makes sense to me! Thank you!

Try global.wemineltc.com

I did, still getting this when I restart the miner, very strange. Can't close it and forced to reboot.

I'm mining at give me coins with approximately 2.2 m/h 24/7 and am pulling less than a coin a day. Everything seems to check out too. no errors and very low stales. how is 1 6950 doing a little less than my 3x7970's and 1 5870?

I will give somebody a LTC if they can show me why I seem to be pulling a fraction of what I should be with no obvious clue's as to why.

2200 kHa/s should yield ~0.76 LTC a day at current difficulty.

 

[lavaheadache]

I just realized that i thought he said .5 ltc and not .05 ltc

 

[Silverforce11]

So I take that 1 LTC from you then.

 

[thilanliyan]

Anyone know why this could be happening while LTC mining? Temps are definitely fine as shown in pic 2.
