Which is louder, this unit or the Ants?

[thenewb]

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

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.

[Cheshyr]

How much is the value declared ?

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

[thenewb]

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

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

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.

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.

Have other specs changed? Top speed?

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.

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.

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.

[Cheshyr]

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.

Do you ship from the US?

Do you ship from the US?

No, we ship directly from China, worldwide.

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.

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.
