CPU MINING
Processor: Intel Core2 Quad Q6600 2.40GHz
Mining Software: cpuminer-1.2c
Hash Speed: 135 khash/s
Processor: Intel Core2 Quad Q6600 2.40GHz
Mining Software: cpuminer-1.2c
Hash Speed: 135 khash/s
That seems really great, but then I started looking at costs:
Hash Rate (KH/s): ~avg 10,000
Power(Watts Rec for 780 ti 250Wat per card): ~600 Watt PSU
Power Cost ($/kWh): 0.15
Current Difficulty: 2765.38251685
Block Reward: 5.57
Pool Fees %: Lets say 2% or .02
DRK to BTC Conversion rate: 0.00960020
BTC to USD Conversion rate: $221.43
Annually @ 24/7
USD: $314.39
Power Cost: $788.40
Fees: $0.06
Profit: $-474.08
So you pay ~$475 a year to mine? It's much worse for us casuals too. I'm curious as to what would be needed in order to reduce power per kilowatt hour and increase KH/s to the point where it could possibly be profitable.
Short answer, buy yourself a masternode's worth of darkcoin and the electricity is negligible and you're ASIC/GPU upgrade proof to boot
try sgminer 4.2 with wolf0's bin files renamed to bin files created by sgminer, you should be hitting over 7 meg I would think. Use xintensity to the maximum its quicker,powertune=20 and overclock a little with GPU memory speed using afterburner.

Some upto date hashing speeds,
R9 290 tri X OC = 7.45 megahash (with Wolf0's bins and sgminer 5.0)
Amd 6950 = 1.9 megahash (pre-release version sgminer 5.0 and x11mod kernel for added stability)
Amd 5850 = 1.45 megahash (pre-release version sgminer 5.0 and x11mod kernel for added stability)
Remember that Wolf0's .bin optimizations do NOT work on earlier chipsets than the HD 7000 series such as the 6950, btw I have managed to get a 6950 over 2 meg but they were usually unstable, I challange anyone to do it and not get a blue screen of death ?!
Tip : if you getting repeated crashing of old GPU's, try underclocking the core clock but keeping the memory clock same or over.

GeForce GTX 750 1GB, ~2660 kH/s
GPU: 1396 Memory: 2504
ccMiner release 1.5.3-tpruvot on Arch Linux x86_64
I'm new to this. The video card seems stable but yet something usually flakes out while I'm asleep, never during the day, and I end up mining invalid jobs all night (BOOO). I think that's related to either my network, or my screenlock?? It will go all day with only 1% rejected then just get wrecked at night... I'm only a few days into this I'll make sure to figure it out tonight.
Anyways, the hashing speeds don't seem too bad to me for a card that doesn't even require a 6 pin power connector, the non-TI version.. I'm not sure how much wattage it uses while mining but you can install these things in any computer with a regular old 300 watt PSU, any old throwaway Dell
This is in an OLD C2D system (E4700), I'm not bothering to mine on the cpu, it has a rather large overclock using a pinmod and I discovered it's not stable both trying to sync the wallet or mining. Crytocurrency makes a good stress-test for sure, I've never noticed any instability before this!

When I look up the hash rates other people are getting with nvidia cards, it seems that I'm doing much better than should be expected. Am I missing something or are the newer versions of ccminer just that good? GTX 750 is a value card it's not that powerful and I thought nvidia was generally not as good as ATI?
Edit: Nevermind, I see other articles with people getting comparable hash rates with the same hardware.

Use Cgwatcher by Justine Milone, set it to reset on dead/low hashing and possibly every 4-24 hrs for good measure whatever.
Useful for running multiple cards as well,
https://bitcointalk.org/index.php?topic=185553.0
That looks really nice, but I'm using linux. I figured, ccminer should be able to run as a daemon, right?
Add a systemd service for ccminer:
sudo nano /etc/systemd/system/ccminer.service
Paste the below into the file, changing username, password, and the location of ccminer (ExecStart line) to match whatever you have
Code:
# /etc/systemd/system/ccminer.service
[Unit]
Description=Start mining DRK
After=syslog.target network.target nss-lookup.target
[Service]
Type=simple
Restart=on-failure
RestartSec=45
ExecStart=/home/MYUSER/builds/ccminer-1.5.42/ccminer --algo=x11 --syslog --quiet --retries=6 -o stratum+tcp://mining.darkcointalk.org:3333 -u MYUSER.MYMINER -p MYPASSWORD
[Install]
WantedBy=multi-user.targetsudo systemctl enable ccminer (If you want it to run automatically upon boot)
sudo systemctl start ccminer (To start it immediately)
I find it often takes a minute to get going, a bit slower to start than just running ccminer from a terminal.
To see what is going on:
journalctl -xe (hit q to exit)
Note that this may eventually fill up your logs (I guess --quiet does nothing? --background seems broken too)
Thanks to the below blog which I used as a starting point
http://blog.woralelandia.com/2014/01/30/howto-cgminer-as-systemd-service/
I cannot guarantee the above will work, and I'm no systemD expert, but I forced various failures on my rig and it seems to be handling them nicely and automatically restarting the service when needed. My system is Arch Linux but this should work for any distro using SystemD
I am a rig-renter as I do not have the luxury to own equipment myself right now, I mine at about 60 to 70 MHs for about a month now. The profitability on DASH is quite amazing and it makes sense price is still kicked down a lot because of how cheap X11 is to mine in comparison to something like Scrypt.
I don't sell my coins by the way. Mining to hodl.

Has anyone been able to mine with the new R9 390's or Fury X yet? Curious about hash speeds on these new cards.

Get me a 6950; I'll get it over 2MH/s
There's also a Fury, which is to a Fury X as a 290 is to a 290X.

You know, I'm considering it, but I'm also moving right now lolI have one lying around, where do I send it ?
Only half joking, I would send it if you wanted, think of all them 6950's you could save from landfills!
Good luck with your moving, try to make sure you move into a strong internet connection area
Thanks - hoping for cheaper power, too!Only half joking, I would send it if you wanted, think of all them 6950's you could save from landfills!

Wolf0 is moving to Thailand.. I'm wondering what's the power cost there, do you know?Only half joking, I would send it if you wanted, think of all them 6950's you could save from landfills!

Ahahahaha, don't I wish!Wolf0 is moving to Thailand.. I'm wondering what's the power cost there, do you know?
You can do it! seriously, easier for you to live anywhere in the world than for anyone else
That's true, but it's not an option for me until I have a bit saved up in case of trouble - gonna have cheaper rent now, though; this means I'm on my way. Can't waitYou can do it! seriously, easier for you to live anywhere in the world than for anyone else
Here's some info for Thailand's utility cost: http://www.boi.go.th/index.php?page=utility_costsThat's true, but it's not an option for me until I have a bit saved up in case of trouble - gonna have cheaper rent now, though; this means I'm on my way. Can't wait
Eh, I like the prices, but it's not another reason to move there - they're just all right. I pay 0.11 USD to 0.12 USD per kWh now.
