the readme doesn't help me so much :/

And it can't unless you actually read it and spend the time doing research so that you can comprehend it as well.

If your unwilling or incapable of moving toward the goal of understanding then I would, kindly, suggest your finding something else to spend your/our time on.

I've try to set up to "thread-concurrency" : "",

But I have this error

GPU0: invalid nonce - HW error

HW error: try lower intensity values (I find 17/18 are what works the best on my hardware).
If it doesn't remove almost all HW errors (<1-2% of shares being an HW error warn you that you are near your hardware limit but that's for you to decide if it's acceptable, the more you overclock the more you risk frying your card), try lowering the GPU/memory clocks.

Didn't say set it to zero. I said take it out "". CGMiner will find a value for you then you can tune from there. Try the Scrypt Readme.

I don't understand what you mean by take it out "".

Sorry I'm noobish with scrypt and the readme doesn't help me so much :/

Set your shaders and take out thread-concurency and the run it.

If shaders set to "1792" and thread-concurency set to "0" = hardware error

But if shaders set to "1792" and thread-concurency set to "22400" cgminer running good with Average 635 Kh/s

Not bad but with a 7950 @ 1175gpu / 1500mem is pretty low if you see the Mining Hardware List, what do you think ?

MY two PCs are stil shutting down because overheating, what can I do to prevent this, how to make cgminer slows down with mining when overheating!

If it is your GPU's overheating then use the auto fan and auto gpu command line arguments.

There are examples in the executive summary in the top post of this thread.

I just got my mining rig up and running tonight. I pointed it a P2Pool to mine LTC. I'm getting a decent hash rate (~500kH/s x 2 7950 cards), but I am seeing a lot of "Stratum from pool 0 requested work restart" in the log -- I mean like half of the entries. I'm also getting about a 30% reject rate.
...

P2Pool has a 10second LP ... so you should on average get one every 10seconds ...

Thanks for your help.

I'm getting these, on average, approximately every three to four seconds (according to the time stamps on the log entries).

If this is an oddity with this pool, I'm not opposed to switching to a different pool. But, if it is something in my settings, I would like to fix it.

Anything else you can suggest?

I'm also getting about a 30% reject rate.

I have tried reducing intensity but that didn't seem to change much except the hash rate. But I haven't tried yet to tweak any of the other settings. The settings I am using are from another guy that is also running 7950s on scrypt to mine LTC. I could post all the setting here if it would help.

First of all, should I be worried? I don't know enough about GPU mining in general, and stratum in particular, to know if what I am getting is normal.

Second, if it is not normal, can anyone tell me what I need to do to fix it?

Thanks in advance for any help you can give.

BTW, I did try to search this thread for that "requested work restart" phrase, but didn't find much that was illuminating.

Can anyone tell me why scrypt mining works fine on 2.11.4 but I download 3.1.1 and use the same .bat and get a force close every time. Nonscrypt mining works fine out of the box with the same old .bats.

how to enable usb autoscan?

If i start cgminer with an usb device already plugged-in, it works.
If i plug it while a cgminer session is running, nothing happens...

regards bcm42

It does already for BFL SC, ModMiner Quad and BFL FPGA
The code for all the Icarus devices (ICA, BLT, LLT, AMU) should be in the next release - except no idea about Cairnsmore1 (CMR) yet.
ZTex isn't coz I didn't write that driver and don't have a ZTex.

Is it possible to use cgminer to connect to multiple pools of different coins (like Litecoin, Feathercoin, WorldCoin)?

I am concerned about this "new block in pool x detected". So lets say I'm mining Litecoin at the moment (pool 0), and a new block in Feathercoin (pool 1) is detected - does that have a negative effect?

As per line 3 of the README, no you cannot.
