Ah I see. That is quite interesting. Thanks. So how do I we use this to mine MMC? It looks very interesting. The Proof of Work is a modified Momentum based algorithm. It has a small SHA512 component, and a large AES component - chips with AES-NI instruction sets will fare *much* better. Each hash requires 1GB of Memory to perform and encrypts 50GB of data. By contrast, the verification only requires 128K and less than one 10th of a second.
Here's how Cuckoo Cycle at 2^{28} nodes compares: It has the tiniest possible SHA256 component (one call), and a moderate siphash-2-4 component. Each instance requires 1GB of memory to perform and hashes 1GB of data. By contrast, the verification only requires 1/3 KB and takes less than one 10th of a *micro* second. Each instance has about a 5% probability of having a solution at the default setting. Memory access in Cuckoo is maximally random, so it's constrained by memory latency rather than bandwidth, and caches are irrelevant. The amount of computation is minimized relative to memory access. See https://github.com/tromp/cuckoo for a paper and implementation. I just design the PoW. It's up to other people to launch new coins that use it:-) They should go with a relatively long block interval though (10min), so they can increase the memory requirement to 4GB or more (where running a single instance takes over a minute). I'm also a proponent of fixed rewards, since the rate of lost coins is a probably a few percent, so even a fixed reward coin can't remain inflationary for long. |

Not sure on that. It could be they draw more power but in LTC mode they seem to draw very little and run cool. I bet if we get the info we could overclock them easily and keep them cool with no problems. I only have one to test but I have seen some others say they had 5 or more running together. It does not mean I am correct I may have misread. They work perfectly on a 49 port hub. I just tested 10 of these.
It's strange, that I was able to run 10 BE USBs on this computer (I have 10 USB ports on the computer) with no issues, 6-7 antminers I remember with no issues, but this computer will only take 2 dualminers at a time? it doesn't recognize any more after that. Do they take more power? I was just running them on LTC mode.
I am able to run them on my multi port hub (separate hub with separate PSU), no issues at all running 10 of them together. I meant, my computer (and 10 usb ports on my computer itself) handled 10 BEs very easily. But can't handle more than 2 of these. Was wondering why! Can it be the power issue? Do they take more power as compares to BEs ? |

Nice to meet you. It looks like a tv show AA meeting in here. LOL Hello My name is Grumpy and I'm addicted to hardware. I started with a purchase of 16 USB block eruptors then purchased a blade for no freaking reason during the $500 a blade faze. Sold the USB sticks and went balls out on a AVALON clone from china 200GH/s. Then when I reached .9BTC I purchased 3 CUBES. Now trying to get rid of the clone to purchase antminers. I feel I am deep in the addiction.

Stick with the 13 drivers the new Mantel 14 drivers are causing some degradation in mining performance others are reporting. nwoolls, Here is my .bat file for my 1x6970 + 3x7970s, the first part to delete BIN was the best thing I discovered on my own. Perfecting these numbers took about a month. I get steady 724k/s per 7970 card with a few HW errors which is worth it IMO. I could lose 100kh/s trying to save that tiny bit of HW error, not worth it. I hope this helps:
So I am trying this again tonight. I have removed all cards except one 7970, and I these are the results I am seeing: https://www.dropbox.com/s/5o04h1x0v7wx4gf/7970-scrypt-a.pngThis is generally the poor performance I see unless I revert to thread concurrency 22400 and GPU threads 1. I'm going to try upgrading AMD drivers next, followed by flashing the BIOS some more. |

Thanks for the fast shipping. I am surprised how easily it just worked. I can't wait for BFG and MultiMiner support though so I can go back to one program controlling my miners. |

I use MultiMiner as well for my BTC and GPU mining. The way I got them to coexist is to start you MuM running and mining first then wait a min then start dualminer. I use a fan on all my USB asics an Arctic Breeze it keeps it very cool. You are right they do take a bit to get up to speed but it stays there great once going. First of, thanks to dm for the GB, perfect, if you are waiting to see if this is legit, wait no longer... i got mine in today, 5 of them on the recommended hub in OP. Mining dogecoin (what else!!!!) on doge.rapidhash.net and they are running as expected, after running for about 5-10 minutes, it's showing 343 on the pool. I haven't bothered to go physically check dualminer, left them running  few things so far... download the dualminer package, already linked above make sure the dip switch is set like you want. there's b or n (dual mode), and a L or T (ltc) mode (all mine were labeled B or L) when installing the usb devices, i put them in one at a time and waited for windows to finish the driver install, then next one. run dual miner after everythings been detected and are ready enter in pool, workers, etc. check the LTC only box I clicked on advanced and unchecked the cgminer console start (might want this in the beginning to debug) Click start, click tab for cgminer output. If you have a few of them, cgminer has to poll and detect them, so it doesn't show up right away, but should pop up with data on this and the LTC status tab. Other things i've noticed they are slow to ramp up to hash speed Questions I have is anyone running them side by side, like 10 in the hub, w/o active cooling, like just sitting there, any issues with this? I have 5 so just spread them out a bit in the hub but will definately be getting 5 more from dm soon as I can find some btc to spare. Problems i'm looking for resolution I use multiminer for my GPU. I use dualminer for these. If you try to run them together, no go. I also had an interesting thing when I clicked stop in dualminer and had multiminer going as well, it stopped my multiminer process. I'm guessing there's some overlap, or API port that's getting confused. For now I'm just running the USB devices. If someone knows a workaround would tip ya! Thanks again for the new toys dm |

Just wanted to share that on the LTC Rabbit website a couple users are going nuts saying it's a scam. I even got called some pretty crazy names which is surprising as usually people there are nice. I even posted pictures. I can say it is not a scam. It works great.   |

I use mc2miner 0.1e version. https://bitsharestalk.org/index.php?topic=2042.0It gets about 20% out of my CPU and seems to stay steady where as the others were not quite as quick or had larger swings in output. The miner integrated with the wallet though is nice and the last couple releases has improved it alot. I have not used it recently though. They also support GPU mining as well. What is the best cpu miner for this coin ? Is it gpu mineable ? If so, by a factor of how much is gpu mining faster ?

Very cool. I use their parent company as vendor for some computer parts when I was still doing tech work. They offer some great discounts you would nver see if you are not a business. I agree on supporting the use of BTC. With your electric bill it might not be so free. LOL I just spoke with Len the chips will be shipped to you in the next day or two. Sweet! Where are you getting them at that price?? I need to get a new one. Well, 12 bitcents will get a nice new Corsair delivered by Friday. We shall see how it looks :-)
Tiger Direct, and it's not the best possible price (I could have gotten it for $10 less at Amazon) but: a) I want to support people accepting bitcoin b) I want to generate more commerce activity in bitcoin c) It's free money, costs me nothing! :-) Actually the 12 cents will come out of an upgrade profits, so technically my business is becoming self-sustaining.

That's cool. I did make them finally co-exist. I had to stop running MMC mining on the system with the CPU. Still can't wait for DualMiner support and MMC cpu mining support in the future. Thanks for the all the work and enjoy the asic scrypt miners. I cannot believe how cool the DualMiner runs. I am sure that they could be overclocked to even better results once they release the info to allow it. Pure scrypt mode it's only warm and cranks out 75 kh/s almost 80kh/s now that I have it on the beast USB hub with the fan blowing over it. I know it is a longshot but any news on adding DualMiner support yet?
I have one that arrived today. It works well on it's custom software but the software will not coexist with MuM on the same system.
Nothing to report yet. Hopefully soon. Luke and I both have some scrypt hardware bits on the way. |

I have been using mine and it works great.
So far I have mined LiteCoin and Doge with no issues.
It run so cool in LTC only mode.
I do have a question?
Are there commands to overclock much like others that you can change osciallting bits? It runs at such a low temp with no active cooling and even better with a fan I bet we could easily squeeze a bit more out of it.
Without doing anything it run about 75kh/s solid.
Thanks excellent product so far.

I agree I just sent an Anker USB hub to Norway. It was real fun making out a customs form. What a mess. Speaking of shipping my DualMiner single arrived today. Works great. It was shipped safe and secure. Thanks. I hope to get more from you soon as I get more BTC. So is this still US-only, or do you ship abroad? From some posts I got the impression
the "USA only" was relaxed. In that case I'd be interested.. Beastlymac's GB simply makes no
sense for small quantities (because of the shipping cost).
To be honest shipping things out of the USA is a PITA.  Its easy to get things in but getting them out is a different story. |

That definitely works. The more the better. It's a great coin. Although my HPM has gone up to about 22, my shares and payout are actually decreasing, seems like we are getting a bit of miners now  . Go MMC! Yeah, almost double the network hashrate over the past two days. Great things are in store for Memorycoin! |

How fast is it going with that on there? This one is my minimal fan, air cooled attempt for the pencil mod. The chip heatsinks are chopped up old GPU or northbridge heatsinks, but they also appear on ebay as Raspberry Pi Heatsink Sets or similar. |

Cool deal literally. Lucky it was not a worse leak in the plastic cup. Also I though baby oil had stuff in it that degraded the board? Very cool.
Do you have pics?
I would love to see how that looks and was done.
It looks a bit of a mess  The soldering was quite simple, some kynar kynar wrapping wire attached to the resistor pads and the other ends linked to the 50K variable resistor. The 50K was all I had, a 10K or 20K would have been better. I set the resistance on the pot to something sensible before soldering it. The oil bath is now version 2. Version 1 used a plastic container which got too hot and melted a small hole, loosing some of the oil. Version 2 uses a glass mug found in our kitchen cupboard, no chance of melting that. The pictures are a bit poor because they are taken through glass, but you can see the green kynar wire and the variable resistor. The level of the mineral oil is a bit low, but I only had 100ml and lost a bit. The grey blocks are just there to raise the level of the mineral oil, just something I had laying around that didn't mind getting dunked in oil. I do plan to add more oil so the last of the chips gets covered and to add more heat capacity. The bands around the board are holding on the heatsinks. I originally fitted these when it was air cooled, they are attached by 3M thermal tape but I thought they would be better if they stayed on, rather than dropped off. Although I did loose one in the transition, you can see one chip exposed. The mineral oil is Johnson and Johnson Baby Oil because its what I had laying around  |

I have one that arrived today. It works well on it's custom software but the software will not coexist with MuM on the same system.
Normally I would move it to a 2nd system but the mainboard had blown up on the 2nd one so a no go until I can get a new MB.
