Mining With LTC

[desnudopenguino]

I started this as a trail off from Here (http://www.xtremesystems.org/forums/showthread.php?281956-BTC-on-the-move-7-USD&p=5183412#post5183412) in an effort to not hijack that thread. This being the case, the thread is about mining litecoin, and configuring it, because I am having trouble getting my cards mining efficiently enough so I thought it would be beneficial to start a thread in case any other litecoin noobs run into some issues.

That being said, the 5770 is running on xubuntu x64 12.04.2 LTS with the fglrx 8.911 drivers. And I am using cgminer 2.10.3 with the following args:
./cgminer --scrypt -o http://ltc.kattare.com:9332 --intensity 18 --worksize 256 --shaders 800 --auto-fan --auto-gpu --lookup-gap 2 -g 1

Thanks you guys in advance. I can throw you a tip if you shoot me your addy. :up:

Switch pools, burnside's pool is ****. I'm at give-me-ltc.com, seeing much better results...like 20% better.

I'm mining on Windows after I spent hours upon hours tweaking on 12.04 LTS, AMD's fglrx drivers are utter crap, it was okay for 5x00 series in 2011 but they are literally FUBAR lately, they don't correctly support the latest X.org so there are no functioning 3D drivers at all for 12.10 for example.

[desnudopenguino]

Ok, cool. I was on xurious' pool but they got wicked unstable, so i jumped over to burnside's pool, but it's been showing the ugly lately as well. I'll give give-me-ltc a shot.

I agree amd's drivers are poop on *nix. At this point, I'm trying to avoid buying win licenses. I may switch though if this gets enough pull from me.

I also rebooted my computer, and now I'm pulling about 143 khash/s. I'll play around with it some more tomorrow after work and life.

Thanks mate!

[BeepBeep2]

People buy those? :p:

I can't help you much with the miner since cgminer and reaper are a little different, but try using a lower aggression level of 17 and instead of gpu_shaders use thread_concurrency 3200.

[desnudopenguino]

I did some tweaking, but i seem to be stuck around 160 khash/s. maybe switching to reaper will help.

[BeepBeep2]

What core/mem speeds?
At stock that sounds about right.

I'm running 930/1280

I agree with amd's fgrlx drivers. I have been fighting them for 3-4 days. I am installing a full 7 install tonight, so that my new stuff can start mining.

those drivers you get from apt-get are outdated

[xsuperbgx]

I tried 13.1 and 13.3. also tried sdk 2.7 and 2.8. I could never get everything working properly. Either it would not mine, or it would not see all of my gpu's. I am not a linux expert, but I have used it a little bit. I tried ubuntu and I also tried a walkthrough on btcforums that used centos.

[Evantaur]

you need to be logged in to a graphical desktop in order to be able to use your ati cards for mining (or anything else) it's an AMD thing

if you just start it up and try to run that command via SSH it won't detect your cards


easiest way to do so is
sudo nano /etc/lightdm/lightdm.conf

and find (ctrl + w)

#autologin-user=

uncomment that one and add your username to it

[Ivanlabrie]

I get 160khash with an oced 5670 man...Jus sayin.
Try Windows 7, guiminer and 13.1 drivers. That just works ;)
Also as beep said, give-me-ltc.com is where it's at. (stratum is neat)

[BeepBeep2]

Please keep this config buried in this little thread...

5770 - ~210-230 khash/s in reaper, 190-245 khash/s measured by pool @ 920/1325, 1-3% stales, no hw errors
Windows 7 SP1, AMD 13.1 drivers w/included APP SDK

Reaper Beta 13 v4 -
gpu_thread_concurrency 9600
worksize 256
vectors 1
aggression 17
threads_per_gpu 2
sharethreads 16
lookup_gap 2

Hey... People are actually posting stuff! Sorry I haven't been back since my last post. Grad school is kicking my butt pretty hard right now, but when I get some time, I will try the settings suggested, and see if I have another copy of 7 I can dig out and use.

And a big thank you to the contributors so far! Mayhaps we could set up an XS pool some time in the future?

[BeepBeep2]

I am actually already a little interested in doing so. :)

As far as windows 7 goes, just don't activate it...:)

[bluestang]

So is it still worth getting into this? I mean I have a 7770 and a 7950 sitting idle right now.

[yojimbo197]

You know, I wanted to get started with this but I had problems setting everything up. Maybe I should add that to my list o' things to do this weekend.

[Elmy]

I wonder what 2 7990's could do.....

[Sparky]

Are you guys doing this actually making any "real" money off this or is it simply a fun side project to tinker with?

Only reason I'd really want to get into this is if it could offset my electric bill by more than it adds to it :p:

I have two friends that each bought eight Radeon HD 7950s spread across four machines purely for Litecoin. They're turning over about $1,000 per month (each), meaning the four PCs are paid off within six months. I'll get a picture for you...

And on another note. Which drivers are you guys using? I know 13.1 is the ideal, but it's old and glitchy with some newer games (my machine isn't a dedicated miner). I'm currently on 13.3 Beta 3, but would like to know how it compares to newer drivers such as 13.4, 13.5 Beta, 13.5 Beta 2 and 13.5 Beta 3.

[Sparky]

:eek:

My single 7950 would easily pay for my electric bill right now, and then some. Wow. Could maybe use it to actually fund some crunchers.

[bluestang]

Does anyone have an "idiot's guide to setting up litecoin".
I have a 7770 and a 7950 I would like to get up and running on win7 x64 using cgminer and reaper and using give-me-ltc pool.

Yeah I second that. I tried setting up on cgminer and reaper using the give me ltc pool and all I got was errors.

Also, my anti-virus tagged my cgminer download.

[bluestang]

Found a guide:

http://www.coinminingrigs.com/litecoin-bitcoin-mining-software/

[yojimbo197]

That guide looked pretty nice.

Unfortunately the bat file they tell you to make didn't work for me. Whenever I double click it, a DOS command window pops up and then disappears before I can even see what went wrong.

[bluestang]

OK, I thought it was just my one PC I tried it on cuz it didn't work for me either.

[bluestang]

Gave up trying the this way.

Ended up using GUIMiner-scrypt (https://bitcointalk.org/index.php?topic=150331.0)

In AMD OverDrive I set core to 885, memory to 1300, fan on auto, power control to +20.

In GUIMiner-scrypt I chose the 7770 preset and then changed the Intensity to 14 as I work on this PC as well.

7770 now running at ~185 khash/s

[bluestang]

After some tweaking on my 7770...

OC'd using TRIXX: 950 gpu, 1375 men, 1125 vddc, +20%
Fan on auto (max 54%), temp 68C max

Why'd you blank out certain details? I'll happily tell the world that my username is "flyingsuicide.1" and the password is "x" - no lies, try it out ;)

All that will happen is any work you do will be credited to ME :D

[bluestang]

Fixed just for you Jonathan :up:

So yes, everyone use my settings please :D

[bluestang]

Just picked up two Sapphire 6970's...should get them Wednesday and have them up soon after on free power :D

Here's to hoping for ~525 kh/s min each card :up:

[bluestang]

I finally got both of these Sapphire 6970's (http://www.newegg.com/Product/Product.aspx?Item=N82E16814202035) going over the past 2 days. Both cards running 940/1450 @ 1.150v and 75% fans (2750rpm). They can peak at 88C for brief periods, but one stays at 79-80C usually and the other that I replaced the TIM on at 75-76C.

Pulling 512kh/s avg per card mining either LTC or DGC with:

-w 256 -v 1 -I 20 -g 1 -s 5 --thread-concurrency 8192 --no-submit-stale
