I never postulated that the account stay locked out.
Remove it on demand but dirty the username (that username is then kept in another table of the database) so it cannot be re-used by someone else.
Easy enough and safer because a quitting user's account cannot be as easily impersonated (wait until someone well-respected, like ckolivas, removes his account and grab the username thus freed).

Let's make cgminer lightweight and easy to maintain.
I say shoot CPU mining in the head and concentrate on relevant tasks.
The last thing we need is stagnation when Conman bogs down in all that ancient code with all its special cases, assembler optimizations and what not.

Sorry, I need a bit of time to recuperate... is that confirmed info?
Is there a reason for not doing server-side account management the right way?
This sounds so 1995 it's not even funny.

That's a good way to do it. Don't disconnect the signal wire though (yellow on 3 pin connectors and green on 4 pin connectors).
This way, you'll still be able to monitor your fan speed.
Be advised that running a fan at 100% will shorten its useful life.

Does cgminer tell you anything on quitting?  Does it grumble about some JSON error or other?

Try either:
   (1) giving cgminer full path to the config file "cgminer -c c:\users\Your_username_here\Desktop\cgminer_directory_name_here\dom.conf"
Or
   (2) rename your config to cgminer.conf and just run "cgminer". This is supposed to work automagically now but I haven't bothered to check whether it actually does. Not under Windows anyway.

If cgminer still isn't satisfied, there is likely a smallest of typoes hiding somewhere inside that file.

EDIT::If you need to post screenshots, don't resize them that small. That's totally illegible.

That's not how it's done! Try here: https://bitcointalk.org/index.php?board=51.0
This way, your offer will be in scope of anyone looking for a new card.

No problem. While cgminer can be a pain to configure, once properly set up it's irreplaceable taking care of your mining, overclocking, and cooling.
Just make sure to set clocks, voltages and temperature ranges to the correct cards and be extra careful if you ever move the cards between slots.

I remember I had to manually set voltages, because - quite counter-intuitively - the default value of 0.000 didn't result in default voltage being applied to each card.
That was a long time ago though and Con might have fixed it by now.

Provided you saved the configuration as my_config.conf, instead of typing "cgminer" to start up the miner try "cgminer -c my_config.conf"
Absolute file path might be required.

What's the point? It's not as if user names are reusable?
He'll start another account if he wishes anyhow.

That sounds like exceedingly heavy penance. Absolution is granted. 

The "common ground" between them might be slightly less common than expected.
As Art already pointed out, the voltage at "ground" might differ between these not interconnected PSUs.
If they power different components of the same PC, current will run where it's not supposed to (from one "ground" to another).
You can fry your components that way. That's not a very likely scenario though.

Mind you, there's nothing to worry about if you're running those PSUs from the same power extender - the power strip will provide common ground anyhow.

I'm happily mining using 11.11 x 2.5 combo. Got nothing bad to say about it.

I suggest you start messing around with vector width settings (vectors 1, 2, or 4) and work sizes (64, 128, or 256).
vectors 2, worksize 128 is a very universal combination.
A couple of my 6770 cards are doing great at vectors 2, worksize 256 while some other oddball mix of cards prefer vectors 2, worksize 64.

Do some benchmarking and fine tuning, you'll get your performance back.
Whichever settings you test, make sure to let cgminer run at least for an hour before writing down the results as conclusive.

EDIT:: P4, are you a couple of miners down or did you point them away from bitminter? Some new pool being tested?

cgminer -c cgminer.conf

There is a whole cgminer thread here: https://bitcointalk.org/index.php?topic=28402.0
The information you seek is right there, on the FIRST page.

Is there any excuse for your not having made acquaintances with the README file? It contains some very useful tidbits of information and is packaged with cgminer.
After you have familiarized yourself with it, proceed to examples.conf which contains example configuration.
Edit it to suit your needs, save under a different filename, load using the -c parameter when invoking cgminer.

Beware of typos in the config file. Cgminer will just terminate if it cannot parse it.
I'm aware that JSON is a total pain to edit by hand but you'll be doing that just once.

Alternatively, you can press S (as in settings) in the main screen of your configured cgminer, then W (as in write config file), enter a filename and there's your configuration.

Good info, makes perfect sense. Thanks Art.

I'll second Notme with this piece by xkcd:


(http://xkcd.com/936/)

That disclaimer should be on by default when trusting any information from the net  

Does the answer to OP's question depend on the type of wiring at their premises?
Does it depend on whether their installation uses three wires (building has its own grounding) or just two (in which case the grounding is supposed done at the power station)?
I do remember reading an article about being supposed to connect ground to neutral if the building isn't grounded and the electrical installation is done with two wires.
...or am I just prattling nonsense?

I don't mean to sound offensive here but I remember clearly you claiming to be an electrician.


If you do work as an electrician and are no expert at what you do, God save the Queen

500W at the outlet? That's just 410W at the DC side assuming 82% efficiency. Yeah, you should have plenty of headroom. I wouldn't expect the 6770 to use more than 120W, even overclocked.
Have fun with it!

The TX series has been manufactured for  Corsair by Channel Well Technologies (CWT), unlike TX v2 (check the model number) which is being made by Seasonic.
This is a common problem with PSU brands: the same brand and wattage doesn't mean the internals are the same or even made by the same manufacturer.

The TX seres uses DC-to-DC conversion and should give you 620 Watts at the +12 rail.
Of course, part of that +12 power is being consumed by the CPU, fans, and drives. The other rails (3.3 and 5v, often called minor rails) are of course also being utilized by the rig, lowering the amount of current you can draw from +12 lines.

I wasn't able to fine overload tests for this exact model but is bigger brother (tx750) has been successfully overloaded by 20% (a total of 900 Watts on the DC side) at the cost of increased power noise and ripple.

You wouldn't have an electricity usage monitor (a popular brand is Kill-A-Watt) lying around?
IMO every serious miner should have on for determining and fine tuning the power consumption of their rigs.
Maybe grab some knock-off from e-bay?

Or, you could give me the details of your rig and we'll try to assess the idle power consumption and thus - how much juice this baby can pump into the cards.

Goat, PSUs aren't made equal.
Wattage specified on the label is next to useless.
A PSU built on an old-design might give you 250W on +3.3V and +5V rails and only 400W on +12V rail.

A decent DC-to-DC PSU can easily supply you with 630W of that sweet 12 volt juice as long as you don't draw too much power from +3.3 and +5 volt rails.

What's the make and model of that PSU of yours?
Also, take a good glance at the load chart. It's right there on the side you your PSU.
