Hashing Speeds

i5 4670k ~500Kh
Sapphire R9 290 Reference Design ~3700Kh
both are left standard (not overclocked)

No HW errors on the GPU and some days 1% rejected shares/parts whatever that is and some days no invalid shares.

Is this good?
 
2 780 ti Asus Dcuii , Win 7 64 Ultimate
1100 clock, stock mem
Speed ranges between 9,886khs and 12,200khs
Temps
55c on card 1
59/61c on card 2
Software = ccminer beta 1.0 x86 ccminer35.exe using stock settings

This is my workstation and its still very usable for daily surfing and video streaming while the miner is active.

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 ;)
 
GPU R9 280x

Sphminer @ 6.3 Mhs with intensity 18
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.

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,

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.target

Save it. Close the text editor.
sudo 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.
 
You need to download the latest 15.6 beta drivers and rename wolf0's tahity bins

Get me a 6950; I'll get it over 2MH/s :p

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

There's also a Fury, which is to a Fury X as a 290 is to a 290X. 11.2MH/s 11.8MH/s on X11 with 15.7 drivers, OC'd to 1125/0500.
