What 7.5-8.0 TH/s looks like.
Dissipating ~24,000 BTU.
Most PSU's = EVGA 1300's, powers 3 S3's each with current to spare.
Bitmain Rocks!

nice......
I would have got more if i could somehow dissipate all these btu's:cannot do this at home at least.
My garage is fully occupied (cars) and no room in the backyard to build a shed (no basement either)
These shelves are some kind of standard or you have a link to home depot/amazon, or something else?

Bought the racks @ Menards in Brainerd, MN. They are available online @ Menards.com

What is not pictured are the 8x 20" box fans at the back door (4'x8' door) moving the heat away from the units.

If interested will post image of back door.

Is this running off of 120 or 240? What amperage circuits?

I am looking at standing up about 20 of these off 2 240v 30 amp circuits and I'm curious about your experience.

Currently, the S3 supply's are running off of 120V.
Will be swapping out the breakers to 240V double poles probably tomorrow.
Using the EVGA 1300's each S3 at a stock clock draws exactly 325W each at the wall or about 975W per PSU (8.125 A @ 120VAC).
So 1 20A Sigle Pole Breaker per 2 PSU's (16.5A draw per 20A breaker).
So @ 240V one should easily be able to run 4 PSU's (12 S3's) per 20A 240V breaker (240V*20 = 4800W).
Am making the swap to 240V cuz' have heard that the EVGA 1300 are slightly more efficient @ 240V than 120V.
And also allows for using thinner gauge wire per circuit.

Think your idea of 2x 30A@240V is overkill.
2x 20A @ 240 would run 24 S3's USING THE EVGA 1300's.
Other PSU's may not be as efficient and hence require a larger current draw.

Hope this helps.

Got the refund this morning BEFORE the physical delivery of the B3's (American Customs and UPS are screwing me violently in the arse). Might (doubtful) show up tomorrow.


Ordering in shipments of 2 units each and using DHL, all of my Bitmain orders have made it from HK to VA, USA in 3 days. Even before they gave the form option, you could always specify DHL in the order comments.
Orders of less than $1000 rarely get stopped by US customs. All of mine have been correctly labeled as BITCOIN ASIC COMPUTER for S1 and S3 shipments.

Just something to consider for the future if you're a US customer.

TLDR: Multiple small orders are less likely to get stopped by US customs. Use DHL.

By ignorance and lack of funds all my previous international orders were qty 2-3. Never dawned on me that as the dollar value got higher it might draw unwanted attention and the resultant delays. Multiple small orders also prevent the hassle when the carrier "loses" the shipment.

DHL in my area is terribly undependable, can relate horror stories of DHL leaving packages in snow banks and not finding them till spring.

Just got an update, customs released the 10 B3's and UPS indicates "Scheduled Delivery Updated To: Tuesday, 07/29/2014, By End of Day". Guess we'll see.

Have 2 B2's clocked @ 212.5, powered by all eight PCI coming out of an EVGA 1300 . Drawing exactly 650W on the Kill-a-Watt.

Stock firmware, no other tweaks save clock speed.

So 325 * 4 = 1300.
Me thinks that's pushing the envelope a little too hard.

That totally sucks, my miner should be delivered today but now "Held in Warehouse" and "Additional documentation is required on the merchandise description". Anyone had the same issue?

Yup just jumped through those hoops.

My shipment was held in UPS's Louisville warehouse over the weekend because "A valid tax ID or deferment number is missing and is required for clearance."
This morning slightly after 8AM they finally called and I fed them my "Tax ID" and supposedly it will be released today and move on towards Minnesota.

Anyway, they are going to want your "TaxID", which translated, is your Social Security Account Number (SSAN/SSN).
If you give them an EIN (basically a business's SSN) you'll likely be charged duty.

Would you guys buy from 112bit.com?

My first 5 S1's came from 112bit.com.
Took my money, shipped fast, and delivered what I paid for.
Goods guys as far as I can tell.

Now I buy directly from Bitmain for less and argue with customs.

10 hours later... and FINALLY WORKING!

it was just the dns. farrrrrrrrrrrrrr out. it literally took 10 seconds and now everything working.

thanks every1 i hope this will benefit others in the future.

what dns   worked for you?    8.8.8.8  or some other one?

on mine I just set the DNS to my ipv4 Gateway & its hashing away fine.  Should it actually be set as something else?

DNS on my 12 S1's and 2 S3's (soon to be 12 S3's) are set to 8.8.8.8 & 8.8.4.4 & 10.0.0.1 (the gateway router) in that order. This gateway router has a static IPv4 IP, so the DNS entries for the gateway router are 8.8.8.8 and 8.8.4.4, respectively. So if the miner can't hit the first 2 DNS IP's it queries the router which then re-triies 8.8.8.8 and 8.8.4.4.

Most home networks use either the 192.168.0. or 192.168.1. nets. So your gateway router will likely be either 192.168.0.1 or 192.168.1.1 versus 10.0.0.1

8.8.8.8 and 8.8.4.4 are Google's universal DNS server IP's and are good globally as they map to local DNS server(s) based on the IP geographical origin of the requesting IP.

So in America, 8.8.8.8 maps to an American homed Google DNS server, but in Russia 8.8.8.8 maps to a Russian homed DNS server.

For us, using 8.8.8.8 & 8.8.4.4 makes our DNS "fire and forget". The only drawback is that Google now knows what DNS queries your gear is making. We obfuscate that information by running all that packet traffic through an encrypted VPN tunnel to one of our VPN servers located in Manassas, VA. So the only thing Google knows is that that server is resolving addresses for the respective mining pool intermingled with the DNS requests of thousands of other VPN users. Done this way it is impossible for Google to correlate DNS requests to a particular miner or the static IP the gateway router has.

Hope this helps.

Have bought from Bitmain before and never seen a UPS message like this.
Am in the US, BTW.
The packages have left Anchorage probably headed for Louisville.

"07/25/2014   9:16 P.M.   A valid tax ID or deferment number is missing and is required for clearance. We are working to obtain this information. / The package is at the clearing agency awaiting final release."

WTF Over?

Anybody got a clue whose tax ID they want.
And what the heck is a "deferment number"?

Thanks in advance,
How many units did you order?  This message means that you have to supply importer paperwork - which is nothing more than filling out a PDF that UPS will provide you - and emailing it back to them.  I had this happen when my SP10 was shipped to me.  I called Fedex about it, and the girl I spoke with said it was because the value was over $2500.

So, just call UPS, fill out the paperwork and your miners will be released and sent to you.

This B3 order was for 10. Grin  Which, BTW, shipped exactly when Bitmain said it would.

Previous B2 order quantity was 2, flowed through American customs without a hitch (just all the S1's I previously bought 2 at a time).

Thanks for the confirmation that international orders like these get "flagged" due to stated dollar value.

Mental note to self, order in quantities of 2 and "stay under the radar".

Minimum order quantities also make sense because if customs flags a particular shipment of a multi-unit order then only 2 would be held up by customs.

Regarding UPS customer service, called them last night, and the twit I spoke to indicated that UPS would call me NLT Monday @ 10:00. So basically I'm on ignore till Monday till somebody in that department gets off their butt and calls. I'm gonna poke around their website and see if I can't find that form you spoke of.

Thanks for the get back. Thought it was something foolish.

Got the email that my first 2 B2 orders shipped.
Order Date: 2014-07-02 06:32:18 (paid for within minutes).
Order on website listed as "shipped".
Opted for the refund, that is still listed as "Init".

Right on schedule.

Orders of magnitude better than Butt F*&^%$g Laboratory (BFL).

Right ON Bitmain!

I was Batch 1 and did not get my Tracking number until the 20th. Did not arrive until Today. Seems I was on the ass end of that deal lol.

Sorry to hear that.

My B2 order got stuck in Chinese customs over the weekend, UPS will deliver those tomorrow (24th).
Got the email my B3 order had a UPS label printed today (23rd).
Both refunds (B2 & B3) still listed as "Init".

BITMAIN Rocks!!

In case of modular PSU do i need to connect the papercllip togheter in any case? How can i do in a batter way?
You'll still need to connect the paperclip, yes.  I believe Minersource has a "Jumpstart" kit that has a toggle switch, but you would have to decide if that's a better way.

The EVGA 1300's are now shipping with a 24 pin snap connector with the correct 2 pins jumpered for us miners.

So I think I got this payout queue threshold thingy wrong.

Would like some recommendations given the following:
Hashing @ 2.2 - 2.3 TH/s
Would like to be paid every 2 - 3 days.

Thanks in advance from a noob.


See link in my sig for payout threshold explanation.  TLDR version: the higher you set your threshold, the sooner you will likely be paid once you hit it.  If your threshold is low (1 day's worth or less) then you could easily see a 2-3 day variance in payouts.

Thanks, sorry to be so redundant. Interesting reading. Maybe make that explanation a sticky? Then it could a RTMFP, lol.

Maybe I'm FUBAR, but if I had 20% of the network hash rate I think I'd be more concerned with what color Lamborghini Aventador I was going to buy next, versus a withholding attack.

I'm with you on that one.

Tesla Model S P85+


One I got the other week from my profits  Shocked

Lamborghini-reventon

So jealous, have wanted an S Model since it was glimmer in the minds of the engineers.

Reventons were very limited production (as were the Siesto Elemento's), hard to find at any price.
Aventadors are common in the new (~$397K) and used markets.
And @ 691 Hp, 2.8 secs to 100, and a top end of 217Mph that blows my skirt up enough.

Yes this block has been/is a bitch.

I track Round Luck Since Last Payout.
For me that was on 2014-06-27 13:49:44 or about 71 hours ago at the time of this post.
RLSLP has dropped to 99.36%, had been >100% prior to this block.
As soon as this block is solved, RLSLP will exceed 100% again.

On a different topic, am VERY pleased with Eligius for a plethora of reasons and can't imagine mining anywhere else.
Thanks WK.
