Topic: OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.0 - page 149. (Read 5806015 times)

I'm not maintaining mining software to help people make profits. I'm maintaining a bitcoin miner because I believe in bitcoin, and while miners are primarily interested in making a profit from mining, I'm interested in promoting and supporting bitcoin, which needs miners and mining software.

any idea of why GPU and altcoins are not supported anymore?, is by FAR the most profitable!
and I mine BTC with asics, LTC with GPUs and a lot of alt coins as well.
I don't understand why GPU mining, which is the most profitable one, was discontinued.

Are you using 3.7.2 or earlier?  That was the last version to support GPU's and Altcoin mining

I am really stuck and frustrated

Someone previously mention to check and see what happens when I type aticonfig --lsa
I get the following:
 0. 01:00.0 AMD Radeon R9 290 Series
  1. 04:00.0 AMD Radeon R9 290 Series
  2. 05:00.0 AMD Radeon R9 290 Series
  3. 06:00.0 AMD Radeon R9 290 Series

* - Default adapter


I am getting the following error message, when I type the following command:
./cgminer -n


 can anyone help me?

It seems that the last version of CGMiner that could find all 5 of my USB Erupters immidiately on every start is 3.6.4
Any newer version of program finds randomly 0 to 5 devices. Sometimes it happens certain device is not found even
after few hours. What exactly is changed after version 3.6.4 that affects USB Erupter detection? Im using Win7 64-bit
but issue exists with WinXP 32-bit as well.

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

Example:

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:

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!

is it normal for CGminer to shuffle pools order when I remove pools via API ?

here my story:
- CGMiner has 10 pool
- the active one is pool 3
- removing pools 0,1,2 (via API call) shuffle the order of other pools, except the active one (3)

...

ckolivas any plans to do a antminer firmware like you done with avalon and knc miner ?

g'day

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.

8gig for 3 290x? or just the one? also what are you mining btc? if so what are you making?

Ok you're right, but let me reformulate the question.

Hi,

I'm a noob in the mining stuffs world. I just have a USB Block Erupter and I want to mine bitcoins with it. I will love know which version do you recommend me to mine BTC with the USB BE in Ubuntu 12.04 LTS.

Thank for your help.
