OK I'm back up and running again, but one H-board I think needs to be looked at. I checked each of the new H-board individually, and one of them doesn't want to play anymore... Every time I use it either in a group with other cards or by itself, it seems to trip up my PSU and everything goes dead.
What can I check with my multi-meter to see if anything is damaged? I checked the big thing with the word "Pulse" on it, since I heard it was a fuse. I do get a little bit of a reading with my multi-meter, so I assume that isn't blown.
I wish MBP would have sent an identical board like what was sent in August. Those seem to be a little more robust.
the 'pulse' cube is an inductor if im correct. i put a tiny heatsink on mine to cool it but its probably unneccessary. the fuse is actually a 'polyfuse' and is the big flat resistor-like item marked F300L or something similar. it is resettable and will work again after a failure if the power is turned off. (intron has a post about it somewhere in the forums) if its tripping the psu, thats not good, and is quite strange. it would indicate that either the psu is having far too much load taken across its connection (what brand/capacity is yours, and how is it wired to the m-board?) or that there is some sort of backfeed from the board. (less likely) I would suggest looking at the small chip located near the inductor/pulse cube. it is the regulator and gets very hot during operation over 0.8V or 32GH. it should be unable to blow or fail (presumably), but from your issue it seems like a potential place to check first for any discolouration or damage. youll know the component by its ~12 pins and the thermal vias on the backside of the board I can't really see or smell anything wrong. I used my multi-meter to test the continuity of components but everything is at least coming back with some sort of reading. The C04 spot may look a little different but it's too difficult to tell. I'm not an expert in this area to begin with... Here are some pictures of what I see. http://imgur.com/a/1ozpu#4I almost rather just sell the card as is for $300 with free US shipping or $20 international. I don't have much free time to deal with it right now. Why dont you do RMA for exchange hboard? |

My order # 64x(for Hboards) is ready to ship that I just got Email.

order 21X still unshipped.  Did you check your page account or email? ps: send email to Dave ask him about your order. Yes, logged into the site an hour ago. Email sent. Dave sent out v1 hboards only. |

Received a shipment notification from FedEx.
I have two H-boards as order 25x, and one H-board as order 34x. Don't know if they were shipped together - no update in MBP order history yet.
Update here as well - via the MBP site. They were shipped together, along with order #406, #413, and #496. Thanks Dave and thanks to your whole MBP team. -R- You did not make me happy and one of your order jump line #46x |

My sd FS dead again and I am using usb flash for FS + sd card for boot up.
ps: happened yesterday morning and I got it up less than 5 minutes.

So it's prob smart to cancel Oct pre-order now and wait for November immediately available order?
once all the october kits and cards are shipped, i expect/hope we will see a drop to <2.5BTC/h-board with immediate availability. This would mesh well with the promise of 2.25BTC store credit on the delayed august stuff
I dont think Dave will have anything for Nov. |

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? I cancelled my extra m-board as well. You could just hook extra power to the m-board but I have a feeling it doesn't work that way. Thinking of canceling my unshipped order if I do not get a ship notice tomorrow. There really is no RIO now at the price I paid. I think will do same thing and I dont want to do it. |

What kind payment Hashfast take or Bitpay only?
Thank you.

I haven't seen a single poster claiming their order has shipped today.
Am I missing something?
Only 2 or 3 buyers got it. |

I dont think 40Gh/s use 70W power but maybe less than that. ps: anymore news on orders ship out today? |

Maybe done with ship out about 600 Hboards and we will wait for next boat.

I still don't get it how come they didn't raised 5 mil $ while HashFast raised 20 mil $ (seems a bit much), Avalon had 8 mil $ for chips and KnC managed to raise more than 5 mil $.
The market got tired of IPOs/pre-orders by the time Cointerra launched. When Cointerra/CryptX went public the miners, investors, and speculators were exhausted and broke from -BFL -ASICminer -Avalon -Bitfury -ActiveScamming -KnC -Hashfast/IceDrill -LabScam -ScamGarden -etc, etc, etc There was simply not enough demand to meet Cointerra's oversupply, everybody was all in and tapped out. Cointerra was late to the party, conceding first/early mover advantage to their more nimble and engineering focused competition. Now they are at least a week behind their self-imposed "first week of October" deadline for tape-out and are desperate to get the rest of the NRE paid. Hence the fire sale on Jan 2014 hardware. No CC and Paypal. |

Any look into building a water cooling system for this. As I understand there are no heat sinks on the board.
What is the spacing between the boards? Is there enough room for a custom water cooling solution?
almost certainly not. unless you have a case for it, the boards likely could not support the bulk size and weight plus hoses assosiated with watercooling, and the cost to implement water cooling for each 25-40GH board would be insane compared to the similar benefits attainable via heatsinks. It would cost roughly $75-150 to put heatsinks on every board in a 400GH kit, and clock it up to >525 for water-cooling, you would see costs of around $200-500 assuming it even fit and was available, and you probably would only get 10-20% better results than the heatsinks. ok, makes sense. Has anyone tried using just heatsinks then? Is there some off-the-shelf heatsinks that would work or is it better to go with something custom made. I can get custom made metal parts made pretty cheaply so that is an option if necessary. I got this one on Ebay http://www.ebay.com/itm/100x140x12-7mm-Aluminum-Heatsink-for-Electronic-Computer-Electric-equipment-H157-/181110341808?ssPageName=ADME:L:OC:CA:3160PS: I will try it when I am going to get my V1 Hboards. That is big, does it cover the whole board? yes, cover the whole board and 140mm a little long but no problem with it. |

Notice on the pool site:
16.10.2013
In recent days we experienced some successful thefts of user's funds using compromised email accounts. We strongly encourage all users to change email passwords. There's no reason to think that pool security itself has been compromised.
Weird, how would slush have access to my email password in the first place? It doesn't say that. It says that people who have passwords that have been compromised from somewhere else who also mine have had their accounts robbed. Unless someone used same password as Email that big problem with some miners. |

No email yet today. Hope they ship soon I can't wait for news. got a response from yvonne confirming that there was some delays, and my H-board from order #13X should ship tomorrow. She also confirmed that my 2.25BTC of store credit would be applied soon. personally, i'm crossing my fingers that they will soon open sales for 2.25BTC H-boards. It would be great payback for the delayed orders and fit well with recent prices (2.2BTC for the 60gh avalon mini) Maybe btc price jump so high and no ship out. ps: order # jump alot by no CC yet. |
