I got it working, but when I try to overclock, it crashes. Got the cards up to 730khs each, but I think I need more ram in order to OC more. Does that sound right?

Unless you watercool them, 730 could be too much

It's an open rig, cards aren't getting over 65*C. They are 7970's

Three of my 7970's are running at 746,788,788 all on air and temps are 68,72 and 74. Mind you I have another 7970 that will not go over 550 no matter what.  For what is is worth my two 290x's run at 880 each and temps are in the high 70's on air. 6 cards spread out over 3 systems all in cases. Two with sides off, of those one has a small house fan pointed at it (ambient temp around 73c) the other is in the garage. My 290x's are also in a case with the side on it in my lounge, again ambient temps are around 73c.

python script after mangling code for personal edits. Very tiny readout, all unnecessary information removed or merged. Displays local time (strftime) instead of server time. Locked to BTC-e for price, removed data grab from Gox.

Just got into scrypt mining with middlecoin. 
First off, middlecoin is great!  Sure, the website isn't very pretty and the influx of newbies like me is causing scaling problems, but it works and is making me more $ than mining LTC and trading them.  Many thanks H2O!  Keep up the good work.

I made a couple of small changes to the python script:

• Support for multiple wallets (I prefer to have a wallet per rig)
• Fixed the "time since json.." bug around midnight

I really wish it was in a proper repo.

Code:

what settings are you using and clocks i can run 1050/1766 to get 720 out of my 7970s or if i run 1170/1950 i get 830 out of one of my 7970s not the other it cant run that high both mine are under water tho.

I know some people have wondered at times which coin we are mining... I found a "kind of" way to find out, and it only works by exception really when a share is not found or something.  There are other ways I know like matching difficulty with known difficulty charts etc.

In order to uncover it, I'm using stratum proxy for my miners and the below shows you what happens when a job is not found;

2013-12-28 16:19:07,167 INFO proxy stratum_listener.submit # [230ms] Share from 'miner3' REJECTED: (-2, u"Job '407' not found", u"Traceback: <class 'lib.exceptions.SubmitException'>: Job '407' not found\n/home/ubuntu/stratum-mining-dogecoin3/stratum/protocol.py:192:dataReceived\n/home/ubuntu/stratum-mining-dogecoin3/stratum/protocol.py:238:lineReceived\n/home/ubuntu/stratum-mining-dogecoin3/stratum/services.py:13:_handle_event\n/home/ubuntu/stratum-mining-dogecoin3/stratum/services.py:81:call\n--- <exception caught here> ---\n/usr/lib/python2.7/dist-packages/twisted/internet/defer.py:137:maybeDeferred\n/home/ubuntu/stratum-mining-dogecoin3/stratum/services.py:78:_run\n/home/ubuntu/stratum-mining-dogecoin3/mining/service.py:100:submit\n/home/ubuntu/stratum-mining-dogecoin3/lib/template_registry.py:187:submit_share\n")

I promise you that I don't use /home/ for anything and I'm certainly not using Ubuntu(I use CentOS6.x because I like certain things about it over Ubuntu).

Hello I have a question. I currently have about 60 servers running with all 3 x R9 290. I use Sapphire and XFX as brand.

1) They run all about 875 khs per card, about 2625 each machine.
2) My temps depend. They are mounted on the motherboard. But I am getting temps from 80 - 94. Is this to high?! When the temp reaches the 94, the speed drops back to 865 or a little lower.

All servers are located in the datacenter with good airflow. But maybe we should consider to change the cassis to get a better temp result.

In short: my question is if the temperatures I am getting are maybe way to high and dangerous for the cards?

Thanks!

Personally I don't like my cards getting to hot and about 85 is when I start to bump up the fan speed or add in another fan. Im currently running R9 290X and getting around 843kh/s with a average temp of around 78 on the high end I get around 81. I have not had any issues so far but I know when I have had cards that got up in the mid 90's they started to have problems and eventually just completely crapped out on me.

[Gamer67]

R290 is rated to max 95c.

It’s important to mention the R9 290’s cooling configuration because the card runs quite hot. By default, AMD sets the PowerTune max temperature to 95’C, which is about 15’C hotter than a GeForce GTX Titan. AMD claims running the GPU at that temperature poses no long-term threat, though obviously time will tell.

When you say yours are "under water", do you mean water cooled or physically submerged in distilled water? if they are submerged, I'd love to see a photo!

[jam3zs]

As everyone seems to be telling their card temps I thought I may as well tell what mine are running at:

Location: England.
Rig Location: My Bedroom with the small, top window open. (yes, it's difficult to sleep)
Outside Temp: 2c - 7c
Other Info: It's built into a cat cage/basket (lol) with a deskfan pointed at it

Sapphire 280X Vapor: 0.75Mh/s  65% Fan  73c
Sapphire 280X Vapor: 0.75Mh/s  65% Fan  67c
Asus 7970 Matrix (flashed to 280X): 0.75Mh/s  65% Fan  76c
Sappire 290: 0.62Mh/s  65% Fan  81c

Total: 2.87Mh/s

In b4 290 should be running faster. I know this, but because it works best on 1 gpu thread and the other work best with 2 gpu threads I chose 2. The only way I can think to get around this is to run 2 instances of cgminer but I haven't worked out how I'm going to go about doing this yet without breaking bamt's graphs. :/

have you tried --gpu-threads 2,2,2,1 or in the config file "gpu-threads" : "2,2,2,1"

You can't specify multiple values for gpu-threads. gpu-threads is a global per-instance setting in cgminer. Not a per-GPU setting so that doesn't work

[linked67]

Just use -d option like:

cgminer blah blah -d 0 -g 2 -d 1 -g 1 ....

Card 0 will have 2 thread and card 1 will have 1 thread.

REALLY?
so I could just delete the line that says:
"gpu-threads" : "2",

and replace it with
-d 0 -g 2 -d 1 -g 2 -d 2 -g 2 -d 3 -g 1

?

[linked67]

I use it in command line for one of my rig with mixed R9 270 (1 thread) and 280X (2 thread).
In the configure file, i don't know how to use it, i just use command line in a script.

Oke, so I suppose I am save!

But then my question: can i make them even faster if I cool them more with an extra fan?
