OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[-ck]

I don't understand how bfgminer got this working without zadig but cgminer needs it?

BFG and CGMiner both used to use the FTDI drivers for USB devices. CGMiner switched to libusb, but requires you to reinstall new drivers. Once you do it one, it should be all set.

I understand that part, but why make people do the extra step?  bfgminer doesn't need it when ASIC's are run there.

Because direct USB is better, plain and simple.

(inb4 Luke-jr's trolling)

Define better.  Hashes more?

Once it's working properly (see caveats regarding multiple lancelot based hardware not working properly so far), lower overhead, lower cpu, scaleable to higher hashrates for the same hardware, less points of failure (no driver between cgminer and the device), lower latencies and finer control over the device. See the Avalon and BFLSC performance for examples of it working successfully.

Hello.

First, sorry for my english.

I want to start using CGMINER 3.3.1, but I have some problems.

I have 2 GPUs. According to the GUIMINER, the card is the 7970 0-0 and the 7870 is 0-1, but with the CGMINER is backwards.
 
Now, in the PCIe 16x is connect 7870, and the PCIe 1x 7870
 
The 7870 with the MSI afterburner up to 1210. And the 7970 up to 1100

This is the configuration I use.

http://pool:port cgminer.exe-o-u username-p password-I 13 - auto-fan - auto-gpu - gpu-engine 1100,1210 - gpu-memclock 950.1060 - gpu -PowerTune 20,20

And I get these values

GPU 0 (7970) -> 680Mhash
GPU 1 (7870) -> 340Mhash

With GUIMINER the values ​​that I have are:

7970 -> 660Mhash
7870 -> 440Mhash


Any suggestions?
Thanks in advance.

I have flip flopped my cards before and the still show up as the same GPU in CGMiner.  I dont know what determines it, and I dont care as long as it doesnt change and my settings get messed up. 

If you are using CGMiner to adjust your clocks, dont use MSI.  CGMiner can control all of your functions right from it (including voltage tweaking).

As for your settings, I think you may need to separate them out and use -d to declare the GPU number you are tweaking since they have different settings.  I havent had much success with that on the command line, I suck at that.  So I use a config file instead (have a 5870 and 5830 in same machine, one running at 1000 and other running at 950).

lets try this again i have two video cards installed. the primary one, a 7970, is in a PCIe X16 slot and  mines fine.  the second, is a 7950 in a PCIe X4 slot and cgminer doesn't see it as being enabled. aticonfig sees them both. i have a resistor in the 7950's DVI connector to dummy it. i loaded the latest catalyst package. Since cgminer mines fine on the one board i'm guessing that the SDK is loaded as part of catalyst? i'm using
cgminer-3.3.1-x86_64-built The MB conector on the X is a full connector and i'm on an extender,

As per the GPU-README... have you reconfigured xorg for the 2nd device? Have you exported the DISPLAY variable? Are you using a driver version that needs a dummy plug? etc..

[Trongersoll]

hmmm... i read the readme's honest.  I ran the aticonfig .... --initial thing. i did export DISPLAY=:0

as for "needing" the plug jumper(Dummy Plug), i figured doing it wouldn't hurt. If the aticonfig isn't the xorg thing you are talking about i'll go read it again. Is there anymore data that i can get ya that might help? I believe this should be working and am baffled that it isn't.

This is what i did to dummy it: http://blog.zorinaq.com/?e=11

Did you do aticonfig with "-f" as well?

Try a different driver version? AMD are awesome at reinventing old bugs with newer drivers.

you are saying that i should try older versions of Catalyst? The aticonfig initialize was copied from the readme and pasted on the command line.

[-ck]

Yes I am saying that.

[Trongersoll]

i think i have hardware issues. i powwered the machine off and it wouldn't reboot until i took the second video card out. I'm going to try some different risers tomorrow.

[PatMan]

Dodgy risers are a pain in the face. Still, better those being screwed than your gpu's eh? I always try to keep a few spares around just in case...

For Avalon users not watching the avalon asic users thread, I have posted updated Avalon firmware with all the overclocking options now in the git master code, and fixed a bug which would occasionally make the avalon fail to start.

http://ck.kolivas.org/apps/cgminer/avalon/20130703/

The new avalon options are:

--avalon-auto       Adjust avalon overclock frequency dynamically for best hashrate
--avalon-cutoff <arg> Set avalon overheat cut off temperature (default: 60)
--avalon-fan <arg> Set fanspeed percentage for avalon, single value or range (default: 20-100)
--avalon-freq <arg> Set frequency range for avalon-auto, single value or range
--avalon-options <arg> Set avalon options baud:miners:asic:timeout:freq
--avalon-temp <arg> Set avalon target temperature (default: 50)


The interface has been modified to allow any arbitrary speed so you can overclock it. Suggest no higher than 325 for batch 1 due to power limitations! Most settle at 350ish, but I set mine a little lower to avoid hardware issues.

[stormos]

Is there a way to obtain gpu hashing speed with Khash/s precision when using  API?
It'll be very usefull for scrypt miners tuning

[xyzzy099]

This may be a dumb question, but I can't find an answer, despite a lot of searching...

When using CGMiner to mine Litecoin (--scrypt) CGMiner reports the network difficulty as ~55.1m, but the Litecoin client says the network difficulty is 841.46756083.

Why do these numbers disagree so drastically?

[Askit2]

I am having a small problem with CGMiner 3.3.1. I have 3 Jalapeno's that reliably get Incorrect result count errors.
It doesn't seem to change my hashing speed and it seems like all valid shares are being sorted correctly.

2 CGMiner instances on Raspberry Pi with 4 Jalapeno's each. Using powered hubs. It doesn't seem like it is a problem but it is putting up a lot of hardware errors and making me wonder if the older firmware is a bit off.

Also Que Job Status failed and Request Que Job Status Failed.
err=-1 and amt = 0 listed below all three errors.

I have a feeling based on my actual hashrate and expected hashrate I am not losing anything or not losing much.

The Jalapeños are all wildly different in quality due to being all the earliest chips out. Just about any amount of hardware errors is pretty much normal. Some are <.1% while others are 10%.

README FAQ

Sorry, I read everything in that README file except the FAQ section apparently :/

Q: Why do the scrypt diffs not match with the current difficulty target?
A: The current scrypt block difficulty is expressed in terms of how many
multiples of the BTC difficulty it currently is (eg 28) whereas the shares of
"difficulty 1" are actually 65536 times smaller than the BTC ones. The diff
expressed by cgminer is as multiples of difficulty 1 shares.
