ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382

[mstrongbow]

Has anyone come up with a cheap water cooling solution for the S3?  I already have a nice waterloop built that i'd like to use with a 34" radiator outside.  Hopefully I don't have to spend an arm+leg on water blocks...

what do you want water cooling for?  you can't over clock most of them.  the stock fans keep the gear pretty cool.

if you set freq to 212.5 it is cooler and pretty quiet .  not whisper quiet but decent.

Not sure what your need for a water block cooler is based on.   for all I know  you may have a really good reason.

I have an existing waterloop in my server closet and I'm trying to minimize heat inside.  I'd also like to see how much OC I could get with water cooling.

There is a video on YouTube of a guy in the Far East, making and testing a waterblock on an S1, but I don't know if he ever got enough interest to take the project to production.

If someone supplied me with some current cooling blocks and/or specs, I can design a 3d printable waterblock setup pretty easily and post them up on Shapeways for others to purchase

might be a good idea.  from what I have read the main problem is on the dc to dc chip.  would be nice to have a waterblock solution as a solution

Yeah I've been tinkering around with a couple GPU cooling blocks for my older 5970's as the waterblocks for those are getting really expensive and with the 3d printed metals Shapeways has to offer I can design and print some GPU waterblocks cheaper than I can pay for new on Alibaba or even used waterblocks.

I don't have an S3, yet but even with just the specs I could probably whip something up but I prefer to test my designs personally. I could always design and print the prototypes for a select few to test for proper fitment prior to placing orders on Shapeways (if I don't have my own S3 for development).

Seems if you had read just one post above you would have seen my post saying batch 4 was listed 

I saw your post, but you did NOT see price and delivery time in mine...missing in yours...

Cheers,

Hi,

How do I use my 10% coupon?

[sveetsnelda]

Fuuuuuuuuuuuuuuuuuuuuu

Has anyone had customs take this long before?  If I had an option to cancel this, I would.  It's going to be two weeks without mining by the time this gets here:

I think item is not clear about something as manufacture, origins, specifications, invoice...
Customs do not accept to export/import it.
If it will be exported from china, i think when it go to your country, it will have same problems with customs in your country

Odd...  I would think Bitmain has sent enough of these to not make that mistake.  Who knows though.  I should probably contact them.  :-/

This time the packages are marked 'Bitcoin Miner', when Bitmain shipped S1's they were marked 'computer gateway' which is a much simpler term, making customs people identify it as a computer part.  'Bitcoin miner' probably sets up their 'does not compute' alarm.
My B1 was delayed for a couple of days in Schenzen, so I contacted UPS.  Their response was "Our records show that the your shipment was held in China due to security screening that is beyond UPS control" - maybe there is some new security alert that causes this - there was recently some news that people carrying electronic equipment for flights need to show that it is 'real', that is charged and functioning, maybe our miners had to be 'quarantined' for a while because of this issue - just speculating.
I hope that you get your miners soon.

Cheers

Have you called UPS to see what info is missing, I would start there.

okay a good reason.  so far it appears the cooling problem is not the chips but the dc to dc regulator.

Maybe of them don't preform well.  If you can get it to cool well I would think you will get an oc to freq 250 and 504gh

i will be replacing thermal paste:

adding heat sinks to regulators:

and more psu's:

and see how that all works out ..

This thermal paste has "only" Thermal conductivity (W/mK): 8.5

I have seen some thermal plates in our Office with 220w/mk
I think, as soon as I have my S3 I will replace the original paste with those ...

[allcoinminer]

I read some articles, the DC-DC controller instability can't be solved just by placing heatsink or "replacing just the dc-dc controller even if its possible".

[pumaro]

So I got my first two antminer s3's but no matter what I do they won't connect to my Eligius pool. They connect to bitminter ok.

One big issue is that in order for the miners to start working I needed to switch from static to DHCP or vice versa.

Anyone else having issues?

be sure it is not electricity conductive ..

i been using this geld extreme for my cpus and gpus has worked well ..

it is pretty much policy for me to replace stock thermal paste ..

when i bring down my S1's i will open one them and have a look under that big heat sink ..

i just did not want to take the time away from mining to mess with it before ..

i am basically replacing my S1 farm with S3's so i will have some time to look at them now ..

What is it...220W/mk...

Could you post the brand of it, specs...where to buy...more details, please...

Thanks,

any opinion on AS5 vs ceramique?
i ordered AS5 from Amazon, but have no patience to wait-will run to microcenter.
i think that I have one asic with no properly applied compound as it always falls to X at 225 and 237.
It could be something else, but i think that it is heating because it performs fine at 218.75

I'm using AS5 for my cpu. Works well.

Here's a nice comparison of thermal pastes: http://www.tomshardware.com/reviews/thermal-paste-performance-benchmark,3616.html

no not really .. i have used the AS5 in the past. i just happen to have been using this stuff lately .
generally if you replace the stock thermal paste you can get a decrease in temps and an increase in efficiency .

@Bitmain

Will Bitmain release a Antminer U3?

greets and thanks

they will not
