Topic: [$0.35/GH] Bankrupted HashFast Hardware Sale - page 4. (Read 5375 times)

The chips have been on sale for months. However they are quite useless without a board of some kind.

Just sell bare chip guys, this is the best bet for you. Nobody wants the boards, just the chips!

so 260 usd  for a kit  so if I run it at 500gh and .8 watts it is the same as an s-3

I have to pay in btc and wait for this kit.

I go to ebay and for  245 I get this

Or 259 I get this

So I just don't see why anyone would want this gear at this price.

I personally have the BOM for the rev3 board, and I would like you to see it. I'm trying to be authorised to share it. Long story short, there is no way the price will halve, and I personally can't understand how they can get this price in the first place. Even by considering the cooling system free, the rest of the components should add up to more than that.

I think that basically HF could make more money off this by selling the cooling systems at $80, that should be below market price. (too bad that the kits are incomplete, and thus can't be sold as retail).

The C1 ships in a few days. This HF unassembled pile of parts might ship in a month. That makes the HF offering way more expensive.

It's actually the opposite. Mounting the cooler with the Yoli is a bit of a PITA, but it's still simpler than the C1 as it's a closed loop cooler. The C1 you need to source the pump, radiator and coolant and then install and fill your cooling loop. Syscool sells a (super cheap) kit that takes care of a lot of the parts sourcing, but it's still more work to get up and running.

It's not worthwhile anyway to try and run as hard as you can. Running at 975-1000MHz (~750GH/s) is a bit hit or miss and can either work reasonably well or require a big bump in voltage to get to that point. Depending on where you are in the chip lottery you could be running from 950W at the wall to well over 1000W to hit that 750GH/s.

Unless you have extremely cheap power, it's better to scale it back to the 600GH/s or so range, where you can keep the power draw at the wall around the 1J/GH mark.

I would be interested in a quantity order even given the history and bankruptcy, but the price point would need to be a lot lower to be competitive.

The Bitmain C1 is an almost perfectly comparable product - .80 J/Ghs at the wall, 1 Terahash, liquid cooling included... but unlike the Hashfast, it is a fully enclosed ready to run system and is priced at 1 BTC / Terahash.  The GB here would be for a product that needs work, and at .80 J/Ghs the performance is 500 Ghs... so to compare apples to apples, you need 2x of the Hashfast to achieve the same results (at .80 J/Ghs) as the Bitmain product, plus I would have to spring for an enclosure, controller/rpi and spend time assembling things...

That makes the Hashfast bankruptcy sale 2x++ more costly than the Bitmain product! on a comparable (J/Ghs) finished product basis.  Plus, I get top notch customer service and after-sale support from Bitmaintech that would not be available form a bankrupt company.

As a liquidation specialist, I would think that Hashfast's trustee could do a lot better than this.  Taking out the cost and trouble of assembly, case, standoffs, screw, etc. and the lack of meaningful warranty (assume they would do warranty on DOA basis, but in bankruptcy sales even that is sometimes not done) .. I would imagine the price should be half of what it is now. 

Suggest that you look at the market again, and come back with detailed pricing and terms that make sense.  Larger minimums may be needed, but at the very least you should have an offering that beats the C1 pricing by a good margin.

Great point MrTeal.  And most consumer 1200+W PSU are not up to the task of feeding hungry maxed-out Yoli boards for very long until they fail (sometimes taking a board with them)!  You could get two 1200W Seasonics, but will pay a premium for their server-grade reliability.

They will, though you'll probably be limited to two boards per chassis if you want to run the Yoli boards full out, unless you want to invest in a couple 1200+W ATX supplies to power three.

i think he is saying that lol...let me flush some money down the toilet instead - easier way to get rid of it.

The empty cases are bulky, but don't weigh very much.  They are custom cut to accommodate three radiator/fans and two PSU, although I'm not sure if the board mounts work with the new Yoli boards.

Which bitcoin colo won't host S3s?

You are right, and they should be like $50 each. They are in the schedules. However that adds to the complexity, and I guess that shipping it won't be cheap.

I think HF still has a bunch of Sierra rackmount cases.  Even if they don't, bare boards are much easier to put in rackmount cases than the nonstandard Bitmain chassis.

Haha pre orders again? I can not imagine anyone is stupid enough to do this...

Nice idea. I understand HF needs to pay for the hardware, but personally I feel if they want to "make up" with the community they can fork over their own money instead of ours.

Thanks for answering my questions.

Those bare boards aren't rackmountable either. You need to setup them like that on your own if you wanted to rackmount them.

Now please go away.

Please note: the image IceBreaker posted has J/GH measurements taken at the chip level. You need to multiply them by 1.1*1.1, but those numbers vary on the efficiency of external and internal transforms (and could be lower).

I was proposing to keep a 2-of-2 multisig address. I would own the first key and HF the second one. For now HF decided that they are not interested into this escrow account, and that if this thread had enough attention, it would have been something that could be done.

However, this escrow account would be only until for group buy purposes, since that the founds would have to be released to HF that would then pay the Chinese supplier completely upfront.

I think that an alternative, like the funds are hold in the escrow account, while HF pays the Chinese supplier out of their pocket, and I release my key only that the majority of the people successfully receive their hardware, could be worked out, if HF had enough cash, that is something I think not to be the case.

Liar. Bitmain products work just fine in a bitcoin focused colo. The Bitmain S3 is far superior to this risky pre-order crap.
