Building a second rig, and currently testing with a single 290x. I get an error when I try to start up cgminer
[2013-12-17 20:02:33] Started cgminer 3.7.2 [2013-12-17 20:02:33] Probing for an alive pool [2013-12-17 20:02:35] Pool 0 difficulty changed to 512 [2013-12-17 20:02:37] Network diff set to 111 [2013-12-17 20:02:37] Error -4: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel) [2013-12-17 20:02:37] GPU 0 failure, disabling!
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?
I've got 2 rigs running just fine with 4 gb. You're the 2nd person I've seen say errors went away when switching to 8. One of my rigs has 2x2 and the other other is 1x4. M

Did you happen to reply to the other guy? I'm interested to see if he resolved the error with the 1x4gb or just went with the 2 sticks.

I did not. His post is a little earlier in this thread, shouldn't be hard to find it. M

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

That's interesting. I'm using 280xs here. (Increase in hash rate from 280 to 290 didn't seem to correspond to price increase...) M

Please move all talk not related to asic or fpga hardware to the alternate currency sub forum. Cgminer doesn't support gpu mining after 3.7.2
Thanks

Thank you and I mine LTC using an older cgminer version. But I want to talk about the new ant miner sticks. there is a custom 3.8.5 version on github designed to run the new sticks. I am having a funny problem I can get up to 13 sticks to run using this custom version but on 2 different mining sites I get very bad underreporting of hashrate when I use more then 6 sticks. when I had the 13 sticks up and running at stock speeds of around 1.5-1.6 for a total of 21gh on the cgminer screen after 4 or 5 hours running at cex.io my avg hash rate was around 11-12gh. The same problem happened running on bit minter. The when I reduced sticks to 6 and used 1 hub vs 2 hubs my rates are closer to correct. 6 sticks avg 8.3 and report as 8.2. So it seems like once I get to 8 or more sticks on either hub even though the cgminer reads okay The mining sites under report the hashing. At 10 sticks at an avg of 14.7gh which is about 1.47 a stick. at no time does either mining site read close to the 14.7 more like 10.1. I am running 5 nano -ice fury sticks on a different hub the read about 12 and 12 which is accurate. I am also mining 11 of them on a different pc and getting good numbers. Now in my case i have more then 50 ant miner sticks and can only run 6 per pc with good rates. I know the cg build is custom but I thought I would point this out.

I plan to send a U1 to each developer once they arrive at my doorstep. Assuming the group buy is filled before the 4th. That should help.

Hi,
I'm a noob in the mining stuffs world. I just have a USB Block Erupter and I want to mine chococoins with it. I will love know which version do you recommend me to mine CCC with the USB BE in Ubuntu 12.04 LTS.
Thank for your help.

That sounds like an Alt Coin. So try posting/cross posting in the altcoin forum for the best advice.

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

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.

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...

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

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.

...
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.
