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.

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..

Building a second rig, and currently testing with a single 290x. I get an error when I try to start up cgminer

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.

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.

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?

[mdude77]

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...)

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.

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

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

[AbraxasCcs]

Thank I'll try it.

Happy New Year To everybody!
