1  Economy / Computer hardware / [WTS] Bitmain Antminer S3 B5 (US 48 only) on: December 12, 2015, 06:40:17 PM
Selling an Antminer S3, Batch 5. Ran in my home office from Aug. 2014 - May 2015 then stored for the summer. I fired it up again Nov. 21st but got news that a family member will need to stay here  Angry for an extended period in my HO.

recent mining:

stats:
pool:

pic:
photochopped pic  Grin <--- not hard....
I'll post a photo of the cat jars plus whatever objects you want (sorry, no Lego ninjas)

S3 is updated to latest firmware. I have always ran this miner at 453GH (225) as it is extremely stable at this speed. Record is 28+ days and I only rebooted because hash rate was showing less than 100GH; pool side was still at 450GH+. Ambient room temp <> 70F.

Will fire it up again on Eligius for the doubters.


$125 + shipping from SW MI (BTC or cash)
Will meet up to 20 miles from 49512 (daytime location w/cameras, bank etc.)
refs: ebay, heatware (daclayman)

Ok all,

It's Thursday, time for the Thursday sell-off. I'm think a manipulation down to 574 on volume of, oh let's go 140 BTC.

The USMS will not transfer bitcoins to an obscene public address, a public address apparently in a country restricted by the Office of Foreign Assets Control (OFAC), a public address apparently associated with terrorism, other criminal activities, or otherwise hostile to the United States.

Lame!

This post made me think. This USMS auctioned BTC will sell for WELL over market value. What easier way would there be to transfer USD indirectly to an anti-American group and only taking a 10-20% hit?

1. No PCI-e connectors - you could chop this thing up
2. Not 80 plus
3. 34A on 12V rail - stock Antminer S1 wants 30A (360W) so you're running at 88% stock speed
4. It's a Coolmax

get this:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013

1. XFX = Seasonic = good quality. I'm running an Antminer S1 on a 6 year old PC Power and Cooling 610W
2. Single 12V rail @ 45A - 30A/45A = 67% + room for OC

edit: 51.99/shipped thru 06/2 w/promo code + $25 rebate = $26.99 + peace of mind

To those of you who have received BTC-refund from KNC

I and also the community (I hope...) would like to track how much BTC KNC have and how much they are mining.

To do this it would be great if you could submit the address from which you received your refund.


Link to address submission
https://docs.google.com/forms/d/15ocLT4yelsQ3TQ59R2x4-TsKXULdAfPB1V6zXrJX-s0/viewform

The only required question is what the address is, takes 5 seconds to fill out and I really do believe that this information is necessary for the community.

Thank you!


Edit: If you would like to share addresses but only to me (and not the world) please submit them here (https://docs.google.com/forms/d/1esjQN8vZwhI1kNtU_qxzQ0xCvhG23sGZryMUAzPMAoo/viewform?usp=send_form)

The address will not be shared further only the information found from it. Ie how much many generated coins, first transaction date. Amount incoming and outgoing. It will be deidentified with rounded numbers and no day specific time.

No need for this. From my refund, I went back through the blockchain and found that KNC pools a slew of BTC (900+ on my refund day) into one address, then creates a new address for each refund, sends the appropriate number of coins to the new address from the pool, then sends the refund to your address from that address.

Those caps look as if they didn't get much flux, and knocked-off fairly easy, and clean. Most of The caps in the pics look like they would solder right back on. Most of the components which came loose look re-usable even, although some look like garbage. The boards are pretty beefy, and the solder points are large. I bet a good portion of the PCB's could be fixed with minimal effort, while others are not.
Someone should head up a group buy effort, and hire a bulk repair shop to whip them out. once they see how simple the repairs actually are, it may be worth the effort... just sayin'.
some place like this....      http://sybesmas.com/site/   could make easy work of a stack of those boards

I live about 40 miles away from this place. Never seen the place, but I'm pretty sure they're using a lot of temp agency for rework jobs. In this area, some businesses would spend 10 cents to save a nickel. I did some solder work recently near here. I'm not saying that you don't have a good idea, I just wouldn't send it to SW Michigan.

You need to clarify: upgraded PSUs on all/some computers? Same problem on all computers with same/different power supplies? To solve an issue, it has to be isolated.

Do the cougar fans come with the fixation screws required, or do they need to be purchased separately ?
If so can you share the length/size of these screws ?

Thanks

No they dont have. You need +30mm screws. You need 1 spacer bolt or something or the cougars go too deep and fan will hit the frame.
Easy assembly but you need 2 screws & bolts for each fan. Maybe 4... i was lazy. Also my bolts were too long for top left corner. Anything longer than 40mm will hit 1 capacitor.




Thank you, just to clarify, will 30mm be insufficient, do i need more than 30mm screws

Also is anybody able to comment on the screw diameter and pitch required ? http://en.wikipedia.org/wiki/Unified_Thread_Standard

Would these screws, for example, work with a space nut ? http://www.pccasegear.com/index.php?main_page=product_info&cPath=83_388&products_id=25486


Antminer with heat sinks and Cougar fan applied.
32mm 6-32 UNC screws with a spacer bolt work perfectly

I am seeing about 300rpm slower fan speed, and about 3 degrees cooler at 400MHz


These work great: http://www.microcenter.com/product/354391/Plastic_Screw-In_Standoffs_For_Pre-tapped_PC_Case_50-Pack

I don't know if those specifically work but plastic motherboard standoffs work great for 120mm fans. BTW, love the little heatsinks.

Hhmmm,

I'm still on the fence. NY, MN and Miami,FL = where are you, Juan?

and a google search of your name is quite impressive.

Pics of end user purchase, warehousing w/your name in pic,
etc would gain my confidence.

Looks bad.

Here's a post about an illegal business based out of the same address 4 years ago.
