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

[rgr_rgr]

when or how can we have support for nanofury usb erupter with cgminer? Is the only programme that can work without problems under linux but it didnt support nanofury usb and i cant use it because i have some of them

There is a patch with a driver available:
https://bitcointalk.org/index.php?topic=321287.msg4086475#msg4086475

For me it works a lot better than bfgminer.

Please can you give a command line or set cgminer you for me ... I have windows 7 32x drivers are installed ok Bitminter client its work ok but another site i fail to make work

Like I said, install the WinUSB driver with the Zadig Utility, per the ASIC Readme file, and use the latest CGMiner.  If you want to use the older version with the Serial Drivers then, I got nothing, as I have never used the serial drivers.

is god to used to minig Litecoin?

is god to used to minig Litecoin?

Do you mean God or good?

[os2sam]

Is (CGMiner) good to use for mining Litecoin?

Your not going to mine LiteCoin's with USB Block Erupters.  CGMiner stopped supporting AltCoins and GPU's after 3.7.2.

If you need help with AltCoin mining try the AltCoin forums.  They are very helpful there.
Take Care,
Sam

I've compiled from github to enable bit fury devices.
3.9.0 on ubuntu against a bi*fury device.

bfgminer will find it, cgminer won't.

Can anyone tell me why sometimes cgminer is trying to submit shares that are under the target difficulty when solo mining...?

Example:

Code:

[2013-12-30 11:34:24] New block detected on network
[2013-12-30 11:37:45] Rejected 0000c804 Diff 83.9k/120491
[2013-12-30 11:39:48] New block detected on network

I don't know why it would even try to submit an 83.9k diff share when the block has a target diff of 120k... Also, why doesn't this share have the usual format of:

Code:

[2013-12-30 11:37:44] Found block for pool 0!
[2013-12-30 11:37:45] Rejected 0000c804 Diff 83.9k/120491 BLOCK! GPU 0
[2013-12-30 11:37:48] New block detected on network

I am using a scan time of 2 seconds, expiry of 120 seconds and I am mining a coin which produces blocks roughly ~2.5 minutes...

Any help/info is appreciated, thanks!

Having some issues with cgminer 3.7 running a single r9 290.



Cant get it to work, I wiped the drivers and installed fresh as well.

Using catalyst 13.11 and SDK 2.9

Have you tried dialing back the intensity...?

Make sure you don't have multiple cgminer binaries installed. Check what cgminer reports it has support built for when you do cgminer -h.

Show us the output of lsusb and lsusb -t. Some USB3 ports are problematic.

Make sure you are NOT building with system-libusb.

Check what cgminer -n reports to see if it sees the device at all. If it does, get a debug output of it starting with -D -T added.

Think I found the issue...

Had to little ram in the system, it only had 4gb, I updated to 8 and now its running

[kano]

Could somebody tell me what does mean and what to do, if I see this message in CGMINER, please?

BlackArrowBitFuryGPIO failed open /dev/mem (13)

I am using Butterflylabs Little Single SC.

One of:
1) Use the binaries in ckolivas main download (see OP post) - they don't have bab support so wont get that error
2) Use one of my binaries that doesn't say "bab" in my backup binaries git (see OP post)
3) When you build it yourself, don't build it with --enable-bab

Now I know the theory of not mixng cards, but at the time of purchase I wasn't aware of this or didn't think it was a problem. I'm running a 280X (aka 7970) and 7950 in the same rig, i thought I'd be fine as its of the same series in a way (?) - 7900 series.

Anyway I'm finding the 7950 hashes better than the 280X with neither exceeding 550khsec. I've tried everything from playing with threads, tc, powertune, running two seperate instances of cgminer with it running 1 and then 2 threads with one of the cards disabled in one of the instances but enabled in other, tried underclocking, overclocking, drivers, sdks and bios flashing. Unfortunately nothing works.

Can someone knowledgeable explain why the cards seemed capped? Is cgminer running the PCIe bus at a speed of the slowest card? Thus the capping and why the 7950 hashes the best even tho its the slower card? Or is it something else?

Has anyone managed to run a 7950 & 7970/280X side by side and get 600khsec+ for the 7950 and 700khsec+ for the 7970/280x? If I remove either card I go up to the famed 600 or 700 khsec. So something (cgminer?) is holding them back.

Fwiw I have more system ram than vram 8gb vs 6gb and run the setx commands...I guess I'm sh&t out of luck but if someone can give me an explaination or maybe resolve it, that would be much appreciated.

Should I run reaper for the 7950 and cgminer for the 280x? That said two seperate instances of cgminer with different thread options don't fix my bottleneck.

NB: Using cgminer v3.5.1 coz of the pool "bug" where it doesn't change back in later versions. In anycase the latest version and las to support gpus is 3.7.2 which has the same bottleneck issue. I run win7 64bit for the voltage control msi afterburner/trixx. I've found even tho cgminer sets the volts it doesn't, unlike trixx/msi ab. Values are checked with gpuz and hwinfo.

hello, i am new to cgminer, and am all ready confused... can cgminer mine every type of coin or just btc?  also when i did run it i got a lot of nothing

on the cgminer i get info like this

(5s):0.000 (avg):0.000h/s

i see the block change every few minutes but most everything is 0, its not like cpuminer were it shows me mining, and i see my hashrate, and blocks found and such

i am so lost, so if you are still sober from last night, please send me a pm, or reply to point me in the right direction

cgminer is a bitcoin miner for dedicated bitcoin mining hardware only. Running it on a regular computer with normal hardware does nothing. You need to actually own dedicated mining hardware to plug into your computer for it to do anything.

ok thank you very much for info, i knew i was missing something obvious..

I'm running on 1 x Corsair 4GB, and google linked me to some forum discussions about increasing RAM to 8GB. I replaced with 2x4 gskills and it worked. I thought a lot of people mine with just 4gb, so is this Corsair stick bad?
