Has there been any discussion about overclocking the X-3?

From the technical news they said they had to increase the number of cores to reach their efficiency target.
They lowered the frequency from 1.5Ghz to 1Ghz.

I thought this would mean if I don´t care about the efficiency I should run it at 1.5Ghz with a stronger PSU. However Black Arrow software says this would not be possible.

Why not? Does it have to do with cooling?


I drew the same conclusion as you but with a few caveats: not only would you need to be able to supply the power (meaning not only the PSU, but also the PCBs and VRMs need to be handle it), you must also be able to get rid of the heat. Moreover, BA would have to provide ways to change voltage and clockspeed. If they say its not possible (didnt read that, but Ill take your word for it), Im guessing thats where the problem will lie.

Of course anyone designing their own PCB and just buying chips from BA might be able to leverage some of that headroom, though its probably not going to be a walk in the park.

This is not as good as our first simulations which were based only on Front End but this is where we need to stop. The time does not allow us to continue our effort towards seeking a lower power consumption.
We had to drop the frequency from 1.5Ghz to 1.0Ghz in order to achieve this efficiency. However we've increased the number of cores so the Minion will hash at the speed promised.
We had met all the timings for 1.5Ghz but the efficiency was 0.8W/Ghash and this is not something we could have accepted.

Hi Matt, could you say what was the cutoff date for payments was to get a Feb delivery order?   Also the 5 days free hosting of the miners, does that start on the 24 Feb or before then?  Can we specify pool info for the hosting mining?

Thank you!

Hi.

This look very nice. I am new to this, so do I have to buy 10 p?
Is there any trusted shop I can order this in Europe, and then only 1?

Thanks and take care

TN

tornie, heres the confirmed official reseller in the UK. https://shop.logicethos.com/

and

Confirmed reseller in the US. https://minersource.net/

Both stores allow you to purchase 1

me thinks Matt needs to add a list of Authorized Resellers to the 1st post so people will find it easier to locate them and not get confused by whatever else is out there.
bitcointalk.org is not the Black Arrorw forums. This information can be found on their forums already http://ecointalk.net/forum/68-general-discussions/


but this is a Black Arrow hardware thread and I see nothing wrong with the suggestion. Particularly in a thread that's gone off topic many times before you seem like a real nit-pic  


+1 in fact he is off topic promoting another forum in here.

Some basic shopping carts wont let you place orders unless it's in stock, ie they can't handle payment for back orders.



Correct.
My shopping cart is the same way.
I just have to make sure in the description it's obvious to the people that it's a Pre-Order.

I hope no one minds, but I tweaked the subject to reflect the current prices.

I also notice the website claims "in stock" ... this seems a bit deceptive to me.

Black Arrow said before that they had problems configuring the store software for accepting pre-orders thus only thing they came up with is adding this note to product page:

Hello,

If there's anyone with a Batch 1 spot for Hosted mining orders that don't feel will be able to pay or decided to go instead for actual shipped hardware, please let me know.
I'd like to take your spot in exchange for some BTC fee.

Please PM me to arrange details.

Thanks,

"ALL ORDERS FROM 1/2/14 ON ARE NOW BATCH 2 ALL ORDERS PAID BY 1/3/14 ARE BATCH 1, PART 2, ETA MARCH 10"

Glad to hear that. Now at least I am being told what I want to hear. I just hope they make good on it  Wink
