I have been mining SHA coins with my erupters, scrypt with my gtx670 using cudaminer, and cpu with cloud miners. I just recently received a R9 280x and want to use that for mining and the GTX670 for display. games, etc. I have the AMD drivers installed as well as created a dummy dvi-vga adapter. Both cards are recognized by Windows when its booted up. I can't though seem to get cgminer 3.7.2 or below to mine with my R9. It, and cudaminer, work fine against the GTX670. Is there anything else I need to install in order to get the R9 mining? Is there a different program I should be using? FYI, hen I run cgminer -n, it appears to detect my R9, but has some errors as shown below: [2014-01-11 16:26:17] CL Platform 0 vendor: NVIDIA Corporation

run a test cgminer command with --scrypt and pool address and login and see what cgminer reports if it works just run cgminer with -d n (where n is the number of the gpu count starting from 0 - the pcie slot closest to the cpu)
|
nope

I have always been taught that both an amd and an nvidia card won't run stable together on the same system because of driver clashes. This might be the problem, if not I am curious how you fixed it because I have a 670 as well and an 280x on the way.

Got it to work and will share how I think I did it in a bit.
Want to confirm first if you need the AMD SDK installed in order to mine with AMD cards?

Unfortunatly I don't know but I will ask in some other forum for you to try and get your question solved as well. EDIT: I guess you do If you have an ATI/AMD card you’ll need the AMD-APP-SDK, which can download here. Also make sure your ATI/AMD drivers are up to date. http://cryptocur.com/litecoin/litecoin-ltc-gpu-mining/ |

OK well I was able to get it working. To be honest not 100% sure what I did. I did have to specify the correct gpu platform, which for me was 1.
So it had to use the --gpu-platform=1 -d 0 to specify the card.
Unfortunately, I am not getting the hashrate I was expecting, with averaging around 560. This is really much lower than I expect so need to play with it some.
I also am unable to read the temp or or other speeds using programs like GPUz, which is frustrating.
Last, but not least, I went out and made a dummy plug as per the overclock topic, but I am able to mine with the card without it, so not sure whats going on.

1. step 1 go to step 2 2. add this to your cgminer command line: -I 13 -g 2 -w 256 --lookup-gap 2 --thread-concurrency 8129 --gpu-engine 1035 --gpu-memclock 1500 --auto-fan --temp-cutoff 95 --temp-overheat 75 --auto-gpu 3. start cgminer 4. watch gpu rise 700+ kh/s 5.  ? 6. profit assuming you've got at least 13.11 driver (13.12 recommended) |
nope

Thanks... what I have discovered is that even with a dummy plug installed, my Sapphire Toxic gets throttled so that I can only achieve a max of ~550khps. Once I plug the monitor directly into it, I can get normal speeds of 700+. I know the dummy plug is working because when I plug it in, Windows immediately shows the second virtual desktop. If i remove it, it disappears. So the dummy plug is being seen by Windows.
Going to play with this some more and see if I can figure out whats going on.

Can you please explain to me how you did it? My 280x arrived today and I have them both running (and able to game) on the same system, but cgminer won't recognise my 280x to mine on.  I have installed only the drivers and amd app sdk for the 280x. |

Run cgminer -n and post the results up to the USB part. We dont care about usb.

Run it from a command prompt. You are missing the info we need. From a command prompt type and in the cgminer folder: Then open out.txt and post that. Is this a dual card system or single card? |

I am trying to run it with --gpu-platform=1 -d 0 like you, but cgminer just keeps running on the GTX 670 RE-EDIT: My bad, apparently there was a setting for gpu-platform in the conf file I got as well. Setting it there and in my bat seemed to got me mining on the 280x. Thank you for all the help! You made me a happy newb  |

Playing around a bit, getting between 600-700kh/s but I don't want it to be too noisy since I sleep in the same room. Can't put it anywhere else. |

Sounds good. If it helps, these are the settings I use: -w 256 -v 1 -I 18 -g 2 -l 1 --thread-concurrency 12250 --gpu-memclock 1500 --gpu-engine 1080 --shaders 2048 --temp-cutoff 85 Some may be redundant. |

I use about the same "intensity" : "13",
"thread-concurrency": "8192",
"gpu-threads" : "2",
"gpu-engine" : "950",
"gpu-memclock" : "1500",
"temp-hysteresis" : "3",
"worksize" : "256",
"vectors" : "1",
"lookup-gap" : "2",
"log" : "5",
"queue" : "1",
"expiry" : "120",
"temp-cutoff" : "90",
"temp-overheat" : "85",
"temp-target" : "80", This keeps it at around 80-85 degrees with quite a bit of noise though and at 640-650kh/s. I'm guessing I may need to add an extra fan to my casing where I get an airflow towards my card so that it doesn't need to pull in all the cool air itself. |

Well this realy helped me My LCD have ports for both DVI and D-sub, So instead of using dummy plug, I've plugged DVI from GTX460 as main monitor, and D-sub from 280x as secondary into the monitor, and set their position so I don't accidentally get any windows to second desktop ____________ |.................| |..secondary.| |___________|__________ ...................|...............| ...................|...primary..| ...................|_________| |
