Used Bitcoin ASICs (KNC, Bitfury, & HashFast) - Accepting Offers

[CoinHoarder]

Please reply to this thread with offers. I am selling these for a group buy, as I have since moved and can no longer host the hardware. So, I prefer all bids be done out in the open as replies to this thread, so that everything is as transparent as possible. All items will be shipped from the USA via the cheapest method possible, you may pay for expedited shipping if you like.

Please submit your offer including shipping and the country to which the ASIC(s) will be sent to. Escrow is available, but you will need to cover the fees on top of your offer, so please consider this before making an offer.

We have the following available for purchase:

1. ONE - Hash Fast Baby Jet
1a. Averages 390 Gh... more or less at stock clock speed... is supposedly overclockable to 750 Gh according to Hash Fast's website
1b. Is the quietest Bitcoin mining rig I've ever operated (since it's water cooled)
1c. Comes with a raspberry Pi in a nice case.
1d. Hash Fast claims it uses about 350 watts, although I have not confirmed this with a kill-a-watt (I don't own one).
1e. This mining rig is extremely stable and has not crashed once since it has been running.
1f. Firmware has not been updated in a while, it could possibly run faster with an update.
1g. Power supply is included

2. ONE - KNC Jupiter
2a. Averages 440 Gh... more or less at stock clock speed
2b. KNC claims 600 watts, but I don't have a kill-a-watt so I haven't tested it, since 1/4th the cores are not hashing I would expect it to use at least 3/4ths the energy.
2c. This rig is extremely stable
2d. This unit was delivered partially working, and about 1/4 of the cores do not work. You may be able to fix them.. I had no luck.
2e. Firmware has not been updated in a while, it could possibly run faster with an update.
2f. Power supply not included, but no host is neccessary

3. TWO - Bitfury "400 Gh*" Full Rigs
* They do not run at full speed
3a. I have had a lot of problems with these rigs as far as stability and speed goes, they will run anywhere from 100 Gh to 400 Gh. To get them to run full speed requires a lot of attention and time. I can only guarantee these rigs will run at around 100 Gh, but with some love and "H card musical chairs" as I've coined it, they can be made to run faster.
3b. The speed decreases slowly over time, and a hard reset (IE. turning the power on and off on the PSU) is the only way to reset them back to as quick as they can run. You will likely need to do this at least once a day unless you figure out how to make them run stable.
3c. Bitfury rates these at 320 watts or less each, since they are partially working it probably uses less.
3d. Power supply not included, but these do come with Pis and do not require a host.

Please reply with your offer including shipping, the country these will be shipped to, and an expiration date for you offer (IE. next difficulty adjustment.)

Thanks

Baby Jet - .39 and I pay shipping
Jupiter - .4 and I pay shipping

The Bitfury sound like a pita, but if we make a deal on the other 2 I will buy them and tinker a bit.

Thanks for the offer. I'm going to leave this open for a bit. I forgot to mention in the OP, please state an expiration date for your offer.. like next difficulty adjustment or whatever you want.

How close was Blazed on the Baby Jet offer?    Was going to offer the same but he beat me to it.

What version H-cards are in the Bitfury rigs?

Well, it seems that may be the best we can get here. I am debating whether we should just throw them up on Ebay or not, but I would prefer to sell them here for Bitcoins as it is easier for everyone.

What version H-cards are in the Bitfury rigs?

v2.2

[CoinHoarder]

Alright, I have decided to go ahead and sell the Jupiter and Baby Jet to Blazed. As discussed through PM, we will use his UPS account to pay for shipping, and I will do my best to get them shipped out tomorrow.

Blazed, please send the total (.79 BTC) to our old group account located at this address this evening: 1MHP7hDgFQw7Q5MUNeP6ecB2srxu8fuezh

If you would like to arrange escrow, please work that out with whomever you would like tonight and forward them the funds, and have them reply here stating they will escrow the deal (please pick someone very reputable if so.) If the payment is received, or the escrow agent confirmed they received the payment, then I will do my best to have the mining rigs shipped tomorrow afternoon.

Please PM me to tell me your UPS account info to charge for shipping and your name/address. Thanks for your offer and for buying the units. I think you will be happy with them, they are very stable machines.

The Bitfury rigs are still for sale.

Thanks all

I will send you my shipping info

How much more for the flakey miner?

[CoinHoarder]

How much more for the flakey miner?

Plz make an offer.. It doesn't seem like anyone's really interested in them. I think something like half price $/Gh sounds fair, calculated at 100 Gh each. I believe you can probably get them to run faster, you will just need to manually reset them every now and then. Laying the rigs on their side helps with the stability.

[Blazed]

.21 for both...toss in with the other 2 rigs.

[btljuice]

I can offer BTC0.1 each (+shipping) for both of the BitFury rigs. I'll take a gamble on them.

[Blazed]

Honestly if you want them...you can get em.  I will just take the 2 other rigs!

[CoinHoarder]

Doesn't matter to me. I have told both of you via PM that the highest bidder gets them.

Thanks

[Blazed]

I will let him buy if he wants...if not I will offer .21BTC maximum.

[zhinkk]

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?

[CoinHoarder]

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.

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

BTC0.22 for both the bitfury rigs. Final offer.

[Blazed]

I am out...max I was going is .21BTC

[Xboxthreefixme]

.23BTC max for both

[CoinHoarder]

I am out...max I was going is .21BTC

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.

[btljuice]

I'm out.

[CoinHoarder]

I'm out.

Thanks anyways.

[CoinHoarder]

.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

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

0.23BTC. I want these!

[Taugeran]

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.

[CoinHoarder]

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

[Taugeran]

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

[TheJuice]

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.

[Blazed]

Both of my miners showed up and are hashing...thanks!
