Don't expect half-price H-boards or rigs to appear on the store any time soon. Tytus and I are not believers in the endless-doubling of difficulty theory promoted by sites like TGB. We'll mine our own equipment before we fire sale hardware.
The competition will soon put you out of business as a hardware seller, if it hasn't already, regardless of what happens to difficulty, unless you drop your prices alot in the next month or two. BTW, will you ever port the improved chainminer back to v1 M-boards? |

Guys, looking for someone with a version 1 M board and successfully running 4 or more H cards
I have 4 cards, without problems most of the time. More are arriving later today. wow, I have two stubborn version 1 M boards, that just wont hash properly with more than 3 H cards. What is your hashrate with 4 cards? Are you using the chainminer that came with the board? Any special settings? Thanks in advance. 138.5 GH total, but 3 chips are dead (2 bypassed and 1 at the end of the chain). I overvolted them to an average of 0.78v. I'm using the stock software. Autotune is off, and some chips are set to 54 and some to 55, based on manual testing. |

has anyone had theirs shipped yet? Looking forward to it and sure hope get it this week w/ overnight shipping  People in the thread have indicated they have gotten their shipments... I am guessing these are the folks that bought many units though. It probably easier to do the boxes of 20 before the onesie-twosies. I'm guessing those boxes of 20 are from the assembly house, not the ones going out to customers. But what do I know. |

I haven't seen a single poster claiming their order has shipped today.
Am I missing something?
Mine shipped yesterday. What number were you? 17x |

40GH/s and 70w per board!? Wow.
That means a full 16-board set should be able to do 640 GH/s at 1120w.
I have a 1250w power supply. I hope thats good enough
Maybe I'll aim for 37.5 GH/s per board and hopefully around 1000w
I'm pretty sure you can't run that much through 2x 6pin connectors. Good point! But you could spread those 16 H boards across two M boards. Ugh, I had an extra M board on order but I canceled it. The M board kit is $1300 with just 1 H board so it really isn't worth it. I'm on the verge of canceling my order. Bitfury from megabigbpower is showing the worst ROI right now, when compared to BitBurner, HashFast, and KNC, especially if a 16-board kit can only do 500 GH/s or so. It needs to be able to do 600 GH/s and arrive in the next week to justify it's $8k cost. I know that the chips are actually capable of doing 800 GH/s as my BitBurner with half the chips can do 400GH/s. The power regulator and cooling issues will limit it though, as for the fact there are only 2 6pin connectors. I'm guessing those two connectors limits it to 600w maybe? ATX PSUs generally are designed to provide 150W per 6+2-pin plug, so actually using more than 300W per M-board could be a problem. |

Here are pictures of my adapter kit for mounting the Hyper 212 EVO to a Chili board. Since I don't have any boards in hand yet, I made a simple cardboard model. (click to enlarge)  Notes: * I recommend at least 3 full turns of the screws into the standoffs from each end for stability. If you assemble them as shown, the screws should meet right about in the middle of the standoff, about 4-5 threads (full turns) from each end. * The number of washers inserted in the center of the X bracket affects the pressure on the chips/pads, though I'm not sure by how much. By my calculations, 2 or 3 washers should achieve the same pressure as the cooler would apply to a standard cpu with the stock hardware. The kit includes 4 washers for that location, so you can choose how many to use. * The picture shows 4 pads, each 10x20mm, which you can cut in half to cover 8 chips. You can probably get away with not cutting them and covering 2 chips each if you position them very precisely. Make sure you remove the plastic from both sides of the pads.* The 12mm long M+F standoffs I'm using for the board's feet, and their nuts, are the ones that come with the cooler and normally attach the backplate to the board. I already sold all 17 parts kits I had for sale, but I still have thermal pads for 6 more boards, which I'll sell for $2 per board plus shipping. Is anyone interested in these kits for batch 2? Let me know how many. I figure I can get more parts in as soon as Monday if there's enough interest (at least 25 kits to make it worthwhile). |

Good news, my order for additional h-boards shipped today Same here. Order #17x is shipping FedEx 2-Day today to California. |

Is that October delivery 400GH kit still accurate? If ordered today, when would it be delivered?
Probably next week since the new M-board will arrive this week. Calculate carefully since those monster 40% is gonna hit in a few hours  No, probably early Nov. Dave said something about cutting short the available quantity because he was uncertain about being able to get much more out by the end of Oct. So we should assume that the last orders will ship out Oct 31. |

I plan on supplying up to 200W (on the DC side) to each unit, so I can overclock the units as much as possible, at least for the first month. As difficulty increases, I'll downclock.
Hrm, fine, ordered a second one. I'll just keep it handy just in case. Maybe if I make a custom replacement for the laptop it would come in handy. Though, what's the cheapest option that can stably run bitcoind, p2pool, *and* bfgminer? For now I'm content with using my laptop because I rarely use it but I would like a more long term solution. The W/GH curve isn't linear. For example, going by some numbers I've seen, dropping from 38 GH to 35 GH could save 40W. That will be a good idea pretty soon. |

Yeah, 200W per Chili is a good budget. At the moment the firmware goes for the maximum hashrate allowed for the cooling solution provided. Colder - faster hashrate. In the future, we'll release a new firmware that will further support underclocking to reduce power. As a couple of data points - in production we're using a TIM that is not very good but is very durable and Chili slows itself down to keep from overheating. This gives around 20GH/s and under 150W. But with a good TIM, we routinely are getting over 30GH/s and more than 150W. Of course we cannot guarantee that speed for all boards, but it seems possible on the few we've tested. Keeping the chips cool will get more hashrate. What are your thoughts on cooling capacity of the Hyper 212 Evo vs the Twin Turbo II, with the 11W/mK TIM? I personally prefer the parallel airflow direction of the former. But I want to be sure I'm not limiting my hashrate. |

I got a 620W PSU for 4 boards according to MrTeal's recommendation, hopefully that's enough.
What model? That seems like it could limit the overclocking potential. |

mr teal,
great job on the project.
can someone post a list of the minimum equipment to get this running (excluding the host hashing system).
For example people are saying
thermal pads
vga coolers
case fans or cpu coolers
I just don't want to get this and have 2-3 days of downtime waiting for accessories to arrive. I assume heatsink and fan aren't included and a gpu fan is required.
a write up of compatible coolers etc in one location would be very helpful
thanks
You'll need a mini USB cable, a cooler, and a thermal pad. I'll be putting the Hyper 212 EVO coolers on mine, and I'm selling adapter kits (including the 11W/mK thermal pads) to mount those coolers nicely on these boards and also support them horizontally (such as on a shelf). You'll also need a power supply that can push ~180W on a 6-pin PCIe connector. Ideally your computer's power supply has a 6+2-pin PCIe plug so you can be sure it's designed for at least 150W. |

so you can put it back on later when you move the HS to your new 50PH/s Intel ASIC machine in early 2015 when BTC hits USD$5000. Haha I think I'm just going to go with the more permanent route since that means I can just go to Home Depot. So when these bad boys ship are you going to provide tracking or is that too difficult? Thanks again! This is exciting. Will we get tracking numbers before delivery? I'd hate to be away from the house when it arrives.
Yes, I'll email/pm tracking numbers once we ship them. |

My adapter kit for the Cooler Master Hyper 212 EVO includes: (4x) M3x0.5 12mm pan head screws (4x) 4.7mm nylon spacers (between raised backplate tabs and board) (4x) 0.8mm nylon washers (between board and F+F standoffs) (4x) 6mm F+F standoffs (connects 12mm screws and cooler's spring-loaded screws) (8x) 0.9mm metal washers (1 between each screw head and backplate tab, and up to 4 stacked between cooler and X bracket) (4x) 1.6mm nylon washers (between board and nuts for board support standoffs) Optionally I can include 20x40mm of 11W/mK thermal pad, which can be cut into 10mm squares for 8 chips. Price for kit is $3. Add $2 for pad. Add a flat $1.69 per order for USPS First-Class shipping within the US. Payment in BTC is preferred. |

Okay, so right now I've ordered the Hyper 212 EVOs and a PSU. I haven't ordered any screws/connectors. Will I need any rubber/metal washers? Here's the two items I'm looking at getting: 2x http://www.amazon.com/Standoff-Phillips-Head-Screw-Pcs/dp/B00CWEL9SO/r1x http://www.amazon.com/Sunkee-Brass-Standoff-Spacer-Female/dp/B00CJS2TBO/Will that be enough screws/standoffs/etc for 4 boards using that heatsink+fan? This is what the screw kit contains according to their site: • (25) 8 mm long M3 #2 Phillips washer head machine screws • (25) 6 mm long M3 #2 Phillips pan head machine screws • (10) 20 mm long M3 standoffs • (10) 17 mm long M3 standoffs • (10) 12 mm long M3 standoffs • (10) 11 mm long M3 standoffs • (10) 10 mm long M3 standoffs And the M+F standoffs bag is a set of 100. M+F standoffs are useless for this project, unless the male end is extra long, and then you'd still need M3 nuts (not the same as the nuts that come with the cooler). The F+F standoffs in that kit are too long and the screws are too short. The screws need to be at least 10mm long, preferably 12mm if you use nylon insulating washers. The standoffs should be no longer than 8mm, and even with 6mm F+F standoffs you'll probably need to add washers between the bracket and cooler to compensate for the low chip height. |

Yes, the cooler comes with a backplate, but it's designed to fit over an existing backplate in Socket 1155 systems. To fit the Chili, you need to mount the cooler's backplate upside down, and then the stock hardware won't reach. That's the reason for the longer screws. My kit also includes spacers to fill the gap to keep it flat. 10mm might be slightly short, especially with the nylon washers I'll put between the board and standoffs to prevent shorting the traces around the holes if the standoff scrapes through the coating. |

Who will need an adapter kit for the Hyper 212 EVO?
I expect to have all the pieces in hand tomorrow (Tuesday), for 25 kits, of which I'll keep 8 for myself. My kit will include screws, spacers, metal and nylon washers, all specifically chosen to properly mount the Hyper 212 EVO to the Chili board at the proper height without shorting anything, and repurposing the too-tall stock standoffs to support the unit horizontally such as on a shelf. The kit will not include the cooler itself, or the thermal pad which can be bought from FrozenCPU. The Hyper 212 EVO, and probably any other Socket 1155 cooler, is only designed to fit boards with an existing backplate and a chip die 7.8mm off the board. The Chili board will not have an existing backplate and the chip dies will be just 1.2mm off the board. I'll try to make some pictures tomorrow.
EDIT: Actually, I have more thermal pad than I need, so could include the 11W/mK pad in 10 of the kits.
