Great 60MHS Scrypt Only Miner Pre-order.
60MHS, 450W.
28nm Chiset.
ship out before May 20th.
LA60M - 15000 USD <including all accessories + DHL express shipping>
Scrypt Miner based on GC3355 stopped production.
More info please. Pictures would be nice. Is it a complete ready to be rack-mounted unit with power supply? What accessories does it come with? Is the "before May 20th" ship date firmly established? Will there be compensation if that date is missed? |

sandor111, great work on your changes to cpuminer! I haven't had a chance to try it but have been monitoring your github. People, please donate...sandor111 is doing some good stuff here. Also, has anyone tried this on xpool.net? Just curious to see now well it works with p2pool. |

For the "power on" mod I pried up pins 3 & 4 and used a mini jumper to connect them together. I looked for the smallest jumpers I could find but even then they were too big so I cut off the plastic shell and used electrical tape. One strip for the bottom and after insertion one for the top. I carefully bent the two middle "posts" of the jumper together to form a triangle and then inserted it into the slot while temporarily holding up pins 3 & 4 with an exacto knife.    Top strip of electrical tape is most likely unnecessary but I threw it in anyway. The first PS took a while (and I almost overly bent pin 4 from constant trial and error) but after that the rest were a bit easier. |

Awesome, yeh I just noticed they said extra heat dispense stuff is needed, they must do a good job to get 1200mhz with the same results as the lower resistor, I am guessing it will probably be at 530khs - Well you know what I have in the mail, 15mmx15mm square 1mm Copper shrims
And some good thermal past better that that silver stuff...
just wondering though with the shrim how would you recommend placing it on the chips? would you do 5 shrims per device and put thermal paste between the shrim and the chip and also between the shrim and the seed heatsink?
What do you think?
Maybe use 1.5mm instead of 1mm? (I read the height of other components are not allowing a good contact with the heatsink) What thermal silicone paste are you using or do you even need any with this pad? |

What's the purpose/advantage of removing the block punishing code? That's an area I've never looked at and am clueless about.
I think that it hurts the nodes that don't have it vs the ones that do? |

the trick is in the wiring!!! looks clean as a whistle but lets see how you deal with the snakes!  Yup! Still waiting on some parts. Will update with pictures after...wish me luck! GL & stock up on twist ties! I'm more into Velcro  |

I'm in at $60  |

I would like to see pics with it all wired up. LOL, I knew someone would call me out on that! Still waiting on the barrel plugs to come in on the slow boat from China (just tried tracking its latest location and the map literally shows it on a boat). Ended up getting copper 16 AWG wire. Also need to buy some wire strippers or borrow a co-workers. Have 18 AWG DC pigtails I might use if I get impatient. Also have 6 way splitters for scrypt but need to cut one open to see what wire gauge it has. that might take a while. i paid around $6 and bought from amazon and had 2 days. yes i paid a lot more but i didn't miss out a lot of time mining. Yea, took a chance knowing it could take a couple of weeks...but I just tracked it again...it's almost here! Processed through USPS Sort Facility

Here's my new case. This one was made using 20mm aluminum extrusions from 80/20, Inc. Previous version used 25mm aluminum extrusions. Currently the top section/shelf is in the universal position as I wanted to try different mounting options. Going to move them closer together for the "on the side" position even though it could just be left as is. If I get more miners I will add a second or even third section/shelf.    ...more info and pictures. |

I stumbled upon the link below and thought of the people having problems with the Raspberry Pi: https://github.com/luke-jr/bfgminer/commit/c993695c521b019b093c222aa810c85c1a82de4bQ: Why isn't BFGMiner performing well or working on my Raspberry Pi?
A: Raspberry Pis have hardware defect(s) which affect USB devices to varying
degrees. Some devices will never be able to work on them, some work fine, and
some require hacks to workaround the problem. One common workaround is to add
the dwc_otg.speed=1 parameter to /boot/cmdline.txt. Note that this will slow
down the USB bus to USB 1.1 speeds, which also affects network bandwidth since
the Raspberry Pi uses a USB network interface. You may wish to consider
upgrading to a BeagleBone or UDOO controller. |

Prices have dropped fast on these...down to $100 a unit. Not nearly the $14.40 price they should be sold at to compete with the Titan but getting there.
Very true, which is why I'm not buying any more mining equipment. When the big script asics come online, even gridseed blades won't be doing you much good. With the difficulty increases you'll be lucky to make decent profit after ROI, if you even get there. Yea, I kinda regret ordering when they were ~$260/each but all in all it's been fun and has kept me busy. ROI will be very tight if ever on them. I know I didn't make up the difference in the extra month or so I had them before they came down to the $95 range. I wont be getting the G-Blade units....might get some more Infinity USB's (what gridseed calls their 5 chip miners now) if the price gets to about $60/each just to fill out my custom case ....and maybe cost average down the ROI a bit....but I'm guessing that unless we get really lucky or do some creative altcoin mining it will be tough. |

If I update the wiibox controller to this can it be reverted back? Does the wiibox controller use cpuminer for scrypt?

Prices have dropped fast on these...down to $100 a unit. Not nearly the $14.40 price they should be sold at to compete with the Titan but getting there. Must resist ordering...next week they may be at $80 For kicks I ran it through the profitability calculator. Not looking good:  |

This is a nice looking case! Not very efficient use of space but still...nicely done. Don't know the dimensions but it appears to be rack mountable. Not sure if they are selling it on it's own but it comes in a bundle with a PS, 20 port USB hub, and Pi for an extra $250.   |

Yes the hashrate displayed is basically (time elapsed x some constant x frequency x 5). So in that sense, hardware errors don't affect hashrate, at all. The way I do it, increment a hashes variable and time_spent_hashing variable, when a HW error occurs the hashes isn't incremented, but the time_spent_hashing is, and thus hashrate drops. That is the way it should be IMO, to get an accurate estimation of how HW errors affect the hashrate. Not using any of those, but Lighningasic firmware (which uses cpuminer) has per chip auto overclocking ATM.
Yea, I knew that about cgminer. I think both are beneficial...but yes, the hashrate cgminer provides does not take into account HW errors. I believe WU shows hashrate minus HW errors but it is currently not accurate/broken. I suspect no one has looked at that part of the code to make it work with Gridseed miners. |
