I had read that a while ago, it says he will do it, but not why.
why keep supporting something that does not generate money and kill what is generating money, that is the alt coins.
I make 10 to 1 in altcoins vs bitcoin mining.
and i have several asics, but they are pointless because they are too expensive, takes way too long to get here an make them work, by that time, the difficulty is so high that they produce next to nothing, in altcoins that doesn't happen so fast, so you can do profit, that's why I ask that.
of course he can do what he wants is his program, is a great program, but i was just curious, nothing more.

Did you read the whole thing? It DOES say why. Let me crop out a few parts:

I am making a conscious decision and taking a stance to only support bitcoin by doing this and will consider all discussions regarding alternative cryptocurrencies as offtopic from here on. It is absolutely clear that we are in a stage where only ASICs matter in mining bitcoin, and cgminer is moving with the rapidly changing landscape that is bitcoin mining.

I honestly think all the alternative cryptocurrencies will go nowhere. The only reason to mine them is to find something that can be profitable by converting it to BTC.

The BTC difficulty is increasing because more and more people are buying newer and newer hardware. The network doesn't just increase by 500x in a one year span without people buying the hardware, and mining on them. CGMiner is at the forefront of running those millions of dollars of hashrate, BTW.

And as far as your ASICs are concerned, it's not Con's fault people bought a bunch of BEs or a Jalapeno and realized they're too expensive / hard to maintain to successfully mine any coins from them. Those ASICMiner devices have always been overpriced. ASICMiner and Avalon units consume way too much power. Those BFL Singles are decent devices. Those AntMiners look very promising. KNC or BitFury are amazing devices. I dare you to ask anyone who has any of those and see if they're losing money.

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.

So idealistic, you'r mine hero. You cant blame people that are raised with Fiat money, keep thinking in Fiat. Most People are about gaining more ,more and more most dont care atleast thats what they learn from the tv/social media and school. I Hope one day the autodidacts/people with utopia thoughts are world leaders. The fiat thinking people point fingers @ bankers, people with big money but when they have the same choice they will probably pick the same shitty Capitalism decisions as the Legal thiefs aka bankers.
I ask everybody with common sense why would a person that steals 1000 dollar from a shop gets months in prison and another person who robs the community to fill his pockets with 200k+ a year gets a bonus?
From this point of view the world is just sick how it works.
We should Honor Roger Ver who just gave millions usd in bitcoin away to people to promote bitcoin. just my 2 bitcents.

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

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.

Just mining my own business...
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.
3.9.0 finds all 22 of my BEs within a minute or two on restart pretty reliably (win7 i3 box using powered 7-port USB2 hubs and an fan to keep them cool). I also am running cgminer 3.3.1 to mine scrypt on a gpu (it doesn't see my BEs), and cpuminer using just 2 threads mining a cpu-only coin just to keep from wasting available cpu cycles Smiley  (I found cgminer had problems managing the BEs if I used more cpu threads mining).  I have 4 antminer U1s running on another machine using a forked version of cgminer since they don't play well with BEs at the current software level of maturity (they are a relatively new device that unfortunately share the same USB ID as the BEs, but the 4 are as fast as my 22 BEs!). 

Bottom line - I've had good luck with the newer versions of cgminer - great devs!

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!

^--- Can anyone please answer this, if it's something that can be fixed/prevented I'd like to take care of it, thanks...

Linux since 1997 RedHat 4
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)

...
You are probably looking at the pool number and not the pool priority.
The priority determines which pool is mining and fallen back to etc.

When you delete a pool (API or screen) the last pool will be moved to the pool position of the one deleted.
The position doesn't affect the priority.

I found a little bug in CGMiner. Or Maybe it's not very well document or not warned.

I have a service of monitoring outside my miner location, and for security reason I open only what is needed for my Cgminer API.
I need this IP range: 215.250.128.0/18 (change for fake) and my LAN, this is a remote shared hosting infrastructure.

But then on CGMiner I should use --api-allow R:192.168.1/24,R:215.250.128/18 but it doesn't work. It takes me a lot of times to understand that the issue is in CGMiner.

Here's what is workin and not:
R:215.250.189/24   OK
R:215.250.128/18  NOK
R:215.250/16         OK
R:215.192/11         NOK
R:215.0/8               OK
R:0.0/0                   OK (obviously)

So, it seems the mask is not as "divisible" as we can expect. It can only handle 24, 16, 8 or 0. And nothing else. Maybe the mask processing is handle to cover decimal IP with points and not binary (or hex) IP.

This is annoying for me. Because I can use "approaching" set up but this is not perfect. It can open security hole or cannot work in some cases... I can also strengthen infosec in setting my LAN router rules.

I talk about bug, but it can be seen as a (lack of) feature. Nevertheless, an update of API-README would worth, or a warning (or error) when using a not-understood netmask.

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

as far as I know the version used on Ants is a fork and Bitmain did not released the source code

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.

i recommend that you turn to the 280x thread in the litecoin forum, there are good tuning discussions going on...

Thanks, M. Seems like 290x requires at least 8.

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

8GB for 3. Just mining via middlecoin.

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.
Umm...3.9.0? It's the latest version and it's quite stable.
