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!

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 ...

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.

Can someone post cgminer settings to mine BTC with Sapphire 7950s please, because I reach 550Mh/s stock and I see people writing about up to 740Mh/s with 7950s.

Thanks!

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.

They must have been taking drugs at the time - ignore them.

I'm having this same issue, except that I am using Windows 8 and the latest version of CGMiner (3.1.1, I think). I have AMD SDK 2.7 and Catalyst 13.1 drivers. I am pretty sure my .conf file is formatted correctly, and I do have settings for "thread-concurrency" : "21712,21712", and "kernel" : "scrypt" and "lookup-gap" : "2,2" in the .conf file. I am running two 7950 GPUs. I have read the scrypt readme file.

What am I doing wrong??

There is only one thread concurrency and look-up-gap value... it is for all cards... That is high, by the way, and an odd setting. I thought they had to be power-of-two... 1024, 2048, 4096, (8192)default, 16384, 32768, 65536

I get that error if I put a non-power-of-two value, or a value higher than 8192 with my 7970's. (My PCIe slots turn into (8x/8x/4x) with 3+ cards installed... but 1x risers used on all cards.) Thus, my setting has to stay as 4096 for stability. Huh

Hi ckolivas,

Competition time?

There's really no competition, IMO.

Can anybody please tell me what it is that I have not right here?

On a USB HDD I have a new install Ubuntu 12.04 amd64, a new install of 12.6 drivers (amd-driver-12-6-x86_64.run) installed with the “run” installer. Installed CGMiner-2.7.5 from the “built” version. Extracted in the directory same way as I have been doing for months.
CGMiner runs as usual on BTC (a truly great piece of work)

However if I try to use “scrypt” for LTC I get these errors. Can somebody please tell me what that means --- in simple terms.

Your nas probably has a weird way of enumerating usb devices. Like the read me says, auto almost never works right.

Have you tried s auto?

Yes, I did. Cgminer didn't start with no error message.
I tried to generate .conf file by cgminer too.
BUT: My lancelots are driven by NAS (arm architecture like pi is) machine, running debian. I'm using cgminer 3.1.1. in screen because of remote access. When I tried to press "S", it cleared terminal and didn't do anything else. Double CTRL+C ended cgminer. I don't know it's cgminer issue, or something wrong with debian or so. My second machine with GPUs is running ubuntu, cgminer 2.11.4 and everything is OK. I didn't try to use 2.11.4 on NSA, because I'm at work just now ;-)

I'm sorry if it was solved here before, but this thread is so huge Wink

Anyone have functional .conf file for multiple Icarus/Lancelot boards?
I don't want to have -S /dev/ttyUSB0 -S /dev/ttyUSB1 .... -S /dev/ttyUSBx ... on command line
I tried to use:
...
"scan-serial" : "/dev/ttyUSB0",
"scan-serial" : "/dev/ttyUSB1"
...

in .conf file, but it takes only the first record, so only one board is mining.
Any help, please?

Well, I seem to have solved my issues. I un-installed Catalyst, and then re-installed it. I also noticed that I was trying to use my "tweaked" core/mem settings from my Gigabyte cards on the new Sapphire cards. Everything in running much better now. Grin
