These went pretty cheap. 1-1.4 TH for ~1 BTC.
Glad this group buy is coming to an end.
EDIT: so it was .79+.25 = 1.04 total. Funny how this is the price of a AM tube now which does 800 GH.

Fair enough. If I ever want another one l, I could always BUILD IT

EDIT: Never mind, I think the units are sold.

If they are setup running:Restart em let me run for 5 minutes then post a shot of the we hi that shows per card hashrate; I'd be willing to entertain an offer on one of them
Or better yet if you have a digital multi meter. Measure the voltage across the inductor to a ground point and let me know. I may know how to fix it them.
Plenty of experience debugging these guys and getting them running solid since I built one from scratch
bareboards and chips to soldered hashing cards a full rig of 16 mini H cards redesigned with trimpots and 8 Bitfury Rev.2 chips running at 400+ Ghash.
That's half the chips doing the same hashrate. ^_^ shoutout to kaerf

Impressive.. unfortunately I spent a hour bubble wrapping everything this morning before I checked this thread. If you would like to purchase them as-is with no guarantee, then feel free to. I really think I am understating the capability of these rigs... as I don't want the purchaser to feel like they got ripped off. I think I have been conservative in how I have described the mining rigs by only guaranteeing 100 Gh each.
----------------
I feel bad about this.. I had already agreed to sell the rigs to btljuice, but I just realized this morning that there are more/better offers now. It is my duty to get the best price possible for the equipment, so I am going to have to back out of our deal.
Right now.. Tupsu has the best offer on the table and I have PMed him to arrange shipping and payment. As long as no one outbids him in the meantime, then I am pretty sure I will sell them to him.
By the way.. I forgot to mention this, but there are actually 2 more H cards than there are slots on the M boards. We got a couple RMAs.. I think those 2 extra cards are dead, but they may be salvageable for chips/parts. They will come as a package deal with the two rigs.
Thank you all for your interest.

0.23BTC. I want these!
August 09, 2014, 11:43:23 AM
.23BTC max for both
Xbox.. I am pretty tired I'm going to head to bed. If you can get your payment to the same BTC address posted earlier in the thread, then these are yours.
Please PM me your name and address, along with how you want to do shipping. I would prefer to get Paypal for shipping, or if you have a UPS/Fedex account that would be ideal. If you can do neither of these, I will get back to you in the morning once I have calculated how much shipping will be.
Thanks
My offer was including shipping. if not im out
My offer didn't include shipping. Let me know, but like I said it was my final offer.
Oops. I guess since blazed's offers didn't include shipping I assumed yours didn't as well. Please send me your addresses. I will determine how much shipping would be and if the price offered is acceptable due to shipping costs.
Thanks

K blazed, I will get your things sent out tomorrow.
I'll leave bidding open for the Bitfurys for a bit.. I think I'll be up for another hour or so.

BTC0.22 for both the bitfury rigs. Final offer.
August 08, 2014, 10:15:11 PM
I will let him buy if he wants...if not I will offer .21BTC maximum.
It seems you got them unless zhink makes an offer above .21 btc
It looks like btl went offline so I guess he decided he didn't want to go above .21
Plz make an offer soon btl or zhink if you want the rigs so we can tie this up.
Thanks

You said #3 operates at 100-400Gh/s and decreases over time. Are you saying it decreases from 400 to 100 over time, or it goes even lower than 100?
It's rated from the manufacturer to do 400 Gh each, and they mostly did for a while but had major stability problems. I think some cards have died since then and they no longer run at 400 Gh.. I would say that you may be able to get them to run up to 200 Gh+, but over the course of the day the cards cut out and it will likely end up around 100 Gh. A hard reset is required daily pretty much, but you could probably keep them above 100 Gh. With a lot of tweaking you may have better luck than I did.. Or if you have experience running Bitfurys rigs.
