Topic: [CLOSED] 1THs 1kW 28nm Miner - $3800 - March 31st, BTC, Wire - LAST CALL (Read 2181 times)

Units shipped on time.  Tracking has been sent.  It looks like all units are out for delivery today.

Shipping expected today.  I will post tracking info as soon as I receive it from China.

Closed

Last call.  Closing this buy in 18 hours.

Vendor announced they are closing orders sooner than expected.  We'll need all orders in by Saturday afternoon.

We've found that these transactions go a lot smoother after a phone call... Not just for credit card, but for all orders. Recent hassles with PayPal mean we have to use our merchant services account for cc's, and for that, we'd rather have a conversation first. It's nothing particular to you, but it is something we'll have to insist upon for credit card orders in the future.

I don't mind paying the fees, I'm a bit skeptical processing the card over the phone thou. Online at least I am protected by the gateway and PCI safeguards.. Giving some random guy my card info over the phone, who knows where it will end up. What is the rational behind taking the payment over the phone, it definitely doesn't offer either of us any additional protection rather it exposes me to a lot more risk.

These look promising, but at these prices they will never ROI.

If u are willing to pay the fees then you can pay by c/c but I must take it over the phone, we can only ship to the billing address, if you want to pay with c/c pls send PM.

These include everything... All you need is an Ethernet connection and a power outlet.

I'm interested in one of this unites.. Couple questions... Is this plug and play with psu and all accessories included? What's the link to your CC payment page?

FYI- We will have spare blades available in our USA warehouse

We are shipping directly from China.

Coincraft A1 Chip can do 25-40 GH/s first Dragon miners were running with stock speed of this chip. 40 chips 25GH /chip 1000GH.
http://bitmine.ch/?page_id=863

All this assuming they really improved blades and DC-DC power to handle the 250Gh ~ 31,25GH /chip instead of old model 200Gh ~ 25GH /chip. For sake of them i hope they tested this so they didnt stress it out too much. If so then it's a good improvement that chips are pushed up straigh from the factory and users dont need to "improve" them anymore. Better to have factory tuned units instead of users blowing them up trying to OC eaven more.

We will see if these OC blades starts to die in future

Older blades were poor in design and underclocked. You should not try to push them 250GH / blade. JointDoctor kindly instructed us lol   dont kill your boards. They knew their design cant handle higer clocks or factory would have shipped 1250GH miners with extra +500$ price. Simple.

I want more of these units so question about shipping. Are you shipping directly from China - EU or will it go from China - US -> EU. I need to pay the VAT so i prefer shipping from China directly.

I see your point.  I'm mostly disturbed at the way they handled it.  It sounds like they are better units though, so it may be better in the long run.  Either way, people are still interested, so we're leaving the buy open.

Why fiasco. Is it not 4 modules and 1 spare slot empty in same case. That makes it possible for user to upgrade with extra module. You get 1.25th from one miner if you have spare psu. You cant do this with original miner because lesser quality components original blades cant be run at 250GH without blowing up.

I see this only improvement in design. They made blades better and got 1TH with one blade less. I have original unit of 40 chips, now i want these new units.

FYI guys, we are going to keep this group buy open, our other factory can not match the price, and these units are proven in quality and we have a good relationship with the engineers for warranty replacement parts. I do not recommend overclocking them. If you attempt to overclock then it will void the warranty.

No, we ship directly from China, worldwide.

Do you ship from the US?

I don't think the move to 32-chip systems was exclusive to lketc.  Whoever provides the majority of the internal electronics appears to have made the move to 32-chip systems permanently.

We're talking to another vendor that has repackaged everything into a 4U case, but they're a touch more expensive.

I'll keep on eye on a new GB. Was about to pull the trigger (since you would take CC) but don''t like the lower chip count.

I'm going to be closing this group buy soon, while we look for another vendor.  Existing orders are secure, and anyone who wants to make a last buy is welcome to do so over the next few days, but this fiasco with the chip count has us looking to find a different source.

The published specs have not changed.  1TH, less than 1kW.  The difference is, if you were planning to overclock these (and void the warranty), you now have less headroom to do so. 

Have other specs changed? Top speed?

I can confirm that the factory has changed the design to a 32-chip design.  I have sent an email to all buyers (at the email addresses they provided) explaining the situation.  Please contact me if you have any questions or concerns.

As mentioned in the other thread, I'm looking into it.  That would explain the $1200 price drop between March 10th and March 18th, but they said nothing about fewer chips; only 1TH 1kW 28nm.  If they changed the product on us, I'm not going to be terribly happy, even if the performance is exactly as promised.

Hi, would you please find out from the manufacturer if this batch has a lowered number of chips and has been overclocked to make up the difference?

Thanks

we can still accept c/c through authrorizenet but the shipping and billing address MUST match or it will not be accepted.

Our default customs invoice will declare value at the price you pay.  We can declare value at another value if you want.

Sorry guys; Paypal is off the table for now.  They've insisted on holding money for 90 days, which makes it impossible for us to purchase your units.  Existing orders from the previous group buy are ok, but we can't use Paypal for this group buy.  Other forms of payment are still ok.

It's about the same.... the 1TH are probably a little louder than 180g ant, but it's not by much.....

Which is louder, this unit or the Ants?
