Ah...!!!
For now, I'm a little afraid to modify my Ants.
Some basic soldering skills, no SMT skills at all...
Thank you, Janezki and miniasic!

Can you give values for higher hashrates? I'm currently running mine steady @ 2.6 (4c81) with HW=0, just wanting to see if I could push it just a bit more.  (2.8 (4d81) is too much, the miner doesn't start) Wow!!! 4c81? Totally curious!!! Anything soldered? Where did you found those values? What sort of black magic did you cast on these things to get it up that high? I can barely run one of them at x0981 (2 GHS) with 0 HW errors and the other at x0881 because if I bump the lower one up, I get mad HW errors, and if I bump the other one up to x0A81, I get about a shit ton of hardware errors...
I am using 0A01 and this is the result I get: cgminer version 3.9.0 - Started: [2014-01-23 13:06:54]

I'd guess this is somehow, stable, althought it isn't the anounced value!! And I get somewhat the same value with 0981. |

So my pencil stroke makes the 1k resistor to be massive out of specs  Hi!!! Glad I've asked, then!  |
|
|
|
|
Just one (perhaps "stupid") question, but...
If R2=5k, Vo = 0.8(*1+1/5) = 0.96V.
Would it be "safe" to put this resistor?
Or is there some strong reason to use the 10k and change R1 to 1.24k?

How are you cooling it and what temps are the cards running at?
You can see from picture. He has "open window mod" . I bet it is a Zelman branded window!! Those windows rock in both functions (open or closed)!! https://i.imgur.com/ckCu8HP.jpg?120x Sapphire R9 290 4x Asus M5A99FX PRO 4x Corsair 750w 4x Corsair 1000w 4x HDD 32Go SSD 4x 4Go 4x CPU Sempron Misc risers Custom wooden rig, match anyone ? Delivering ~16.6 Mh/s Burning ~6500W (distributed on 4 circuits of 10 amps each) Working on a much better 19" rackable rig, cause this beast can't scale no more. No way I'm going to put a third level on this thing  That is quite neat! Congrats! |

http://www.pugetsystems.com/mineral-oil-pc.php << this site addresses the heat issues (explains how to make sure the heat dissipates well) as well as issues 2 and 3 (they look neat and kind of beautiful) and if sealed properly they are as safe as a fishtank around pets/children.. As for issue 1, yeah, I wouldnt buy an oily miner lol however, maybe there is a way to safely seal them prior to immersion and still retain most of the heat transfer? some kind of simple to remove airtight shrinkwrap that also conducts heat well? I dunno lol that one has me stumped. Well, the issue is that the metal parts of miner have to be in oil (it will not work without it, lol). Meaby putting just the heat sink to oil or connect it somehow with the bowl with oil (some extention form heat sink to oil meaby?). And I found that you in fact can overclock U1 to mine 3 - 4GH/s but you need proper cooling(like water or oil...or if you live in Canada, you can simply place it behind your window ) or error rate will be 90 - 100% How about non-scented baby oil? Read somewhere in this forum that it works great!! Wel, it could work... But oil would stay on device, I think... I will do some research about it today... Not quite as: You can remove oil with acetone or isopropanol very easily.
Although I strongly recommend avoiding acetone!! The best is colourless baby oil, which is quite cheap (I guess!) and clean it with mineral tupertine (also cheap) which is quite harsh with the oil and very soft with all the circuit and components. (Big thanks, Trillian!). After cleaning, just put them half an hour under a fan and they'll be good as new!! |

Why haven't you pasted the print screen in paint, at least and posted the picture? Also, what's the story with AMU10? Dropbox is a habit inherited from other threads that complain about re posting with pictures. I think AMU10 is just about hanging in for the ride. It appears to prefer stock speed. The hubs are 2 x 10 port Orico with 4A psu's cooling is a cheap laptop twin fan cooler. They are running on a Zotac Mini PC along with 70 erupters (there may be another 10 weeks of returns in the erupters) BFG is launched with a .bat file with the comand line "-S amtminer:all" "clock=x0981" The erupters are on another session of BFG "-S erupter:all Don't worry, we prefer pictures. You have 5 in each hub, and a 4A psu in each? It seems to misbehave by lack of power, the error rate is huge!! |

get over it. these used to mine bitcoin, and already people are having a big-enough hissy fit over it to create a 'no-scrypt mining rig' thread for people like you
IMHO: that other thread is stupid. I like seeing GPU rigs regardless of what they mine. they are creative, home-made, and often finely tuned. The pictures of ASICs are just a shiny box in the corner or a half-filled USB hub (which is almost just as big a waste of money as mining bitcoins on a GPU)

since GPU mining for scrypt coins isn't bitcoin, aren't posts here about it in the wrong place? shouldn't they be posted in the altcoins section? So of course GPU mining is looked down on. it is either unprofitable or being talked about in the wrong place. (Bitcoin Snob here)
I agree that GPUs should be banished from this thread since they are no longer viable for bitcoin mining to make a profit. Glory to ASIC! Sorry to burst your bubble but there are distinct and valid reasons to be using GPU in 2014. Or were you trolling? Some of these rigs people are posting images of cost over $6000, do you really think that they would go to great effort to design and construct these custom systems and not do a few calculations to prove they are viable and profitable? +1 He must be trolling or ignoring uses for the GPUs... Also, this is the "Pictures of your mining rigs!" topic, not the "Pictures of your bitcoin mining rigs!". |

I have nothing else than the original heatsink and a fan blowing through them (not from the top but from the side). How are you getting your U1s to run at full speed with your BEs on 3.9.0?? What is your command line or .conf? When I try running my U1s and BEs together, the U1s run just 20% or so faster than the BEs on my win7 box. TIA! Hi!! Well... my command line is just: I run cgminer from the configuration file in /home/myuser/.cgminer/cgminer.conf {
"pools" : [
{
"url" : "pool1",
"user" : "user",
"pass" : "pass"

"icarus-options" : "115200:1:1",
"icarus-timing" : "short=90",
"kernel-path" : "/usr/local/bin"
}And no, that's not a typo! :p I'm running Linux. No zadigs, no usb drivers, just complie, plug and have phun!!! But without more jokes, I believe you could improve the speed with a configuration file similar to mine or, with the parameters I have. I believe in windows they would be: cgminer.exe --bmsc-options 115200:20 --bmsc-freq 0981 --icarus-options 115200:1:1 --icarus-timing short=90 I'd apreciate if someone could correct me on this. |

Also, this cgminer usually takes long to find the hardware (about 2 minutes) and if I set the frequency to 0A81, the ants aren't even detected.
I noticed this as well. It is especially bad if you have both BE's and ANT's. The BE's have to fail ANT validation 3 times each, and this takes time. I have thought it would be nice to fix that but given that I restart my miners once a month or so I figured I can live with it. Even if for some reason I have to restart once or twice a week, I can also live quite well with it!!! I'd even wait for 5 minutes as long as it worked! (Just got "scared" in the first few times! :p) Once again, great work, Fractalbc!! |

Just recompiled with libusb-1.0 support and it took about 30 secs to start. I can live with that! Also try tightening the U1's Allen key bolts a little. On my 3 ants (that's a total of 6 bolts) 2 of them were fine, 2 needed half a turn and the other 2 were very loose needing over 1 full turn.
I haven't done them up to superhero tightness, just nipped them up. May help with heat & speed issues. Just for ref, my 3x ants in a raspberry pi (with powered hub) tend to average 0.40 or lower HW errors (they do have fans cooling them however).
Most Ant's will experience issues if overclocking to 0A81 (2.2ghs) due to voltage and obviously heat issues. My CGminer takes about 15-20 seconds to initialise and start mining.
Got to check mine then. As for overclocking, 0A81 needs the resistor or not? I thougt that the resistor was needed to 0B81 and up! And yes, if overclocked, they would need to dissipate massive amounts of heat and in that case, bigger heat sinks. |

Looks good except AMU 6...any idea why that one is so out of whack from the others?
Yap... I think I have some problems either with the PSU or some regulator/capacitor on the motherboard, so I had to plug the AMU6 directly on the back. Since I'm having that problem, i can't use an extender or an hub to plug it. Since I'm also waiting for a 5V@8A power adapter to my 10 port USB hub, I can't plug it there, neither. So, it's heating away... with a very bad cooling from one of my case fans and a piece of cardboard. I've spent about 1h trying to put them all up yesterday night. BTW, I'm on Linux and I can't get the compiled BFGMiner to detect them... not even the the BES or the Jala even with "-S erupter:all -S antminer:all" or "-d?" (0 devices) so, i use Fractalbc's cgminer. I wanted to test with bfgminer, but it's a no go. Also, this cgminer usually takes long to find the hardware (about 2 minutes) and if I set the frequency to 0A81, the ants aren't even detected. (mean while, I've found I've missed libusb-1.0... :p I'll recompile both cgminer and bfgminer and try again) |
