DPS2000BB Breakouts. New updates!

[Optimizer]

Hello fellow miners.

I have been working quite diligently to turn a few things out to improve my own miners.  In time, my goal is to replace all of the hardware within my GPU miners (barring processors) with hardware of my own design.  For those of you that have seen my previous posts, some of what you see below may be redundant.

I have designed a 2kW and a 4kW variant of the 2000BB breakout boards.  They are quite nice performance-wise and now I am on the second generation of product improvements.

I have increased the weight of the copper in each variant to keep the ambient temperature rises to a minimum and have made a few updates on the 4kW variant to improve reliability and use for ASIC miners.

For now, let's look at the 2kW variant (Please forgive my photos, I am an engineer, not a photographer ><).



To match the demands of some of the newer ASIC miners, I have increased the PCI-e count to 15.  This is on par with the 30 connector need of the 4kW variant now.  I have left the jumper for those that prefer to have the option of remote network switching to disable their supply.  There is also still room for those pesky 4 pin fan connectors.

The new thermals are better as well.  I have increased copper weight at the risk of manufacturing costs, but the results are quite nice.  I ran this board at 2kW+ load and am finding the maximum ambient rises are around 40C-50C with no airflow (The power supplies will suffer in these conditions).  Keep in mind, my ambient is around 20C-23C.

I have also come up for a solution for some riskier environments where moisture is a pretty big deal.  Since I have been playing around in the EU market, everything I do has to be RoHS, but the damned tin is prone to whisker growth.  To combat this crystalline formation that will destroy mining systems, I have begun implementing  special coatings to seal the tin connections away from hazardous environments.  This coating is normally undetectable via visible light, but this coating can be verified via blacklight/UV.



With this, I am planning on power systems that rarely degrade with time, so my only real concern is turning my video cards.

The 4kW variant has gone by on the forums with little announcement since it has been quite a hurdle.  But now, it is ready for  more critical viewers.  Everyone seemed to need around 30 PCIe connectors for their S9s, so I have made the second variant with 30 PCIe connectors.

4kW Top View


There are also 4x fan connectors and two separate jumpers for independent network control of each supply.  I have also upgraded the board so that each supply is controlled through isolated circuits, to prevent flame outs if one of the supplies fail and the system attempts to shut down both supplies without success.  This is important given some of the behavior I have seen in the past.  The copper weight has also been designed to match the performance of the 2kW variant.

Interestingly enough, I have tested this board close to 4kW and I am having quite a bit of trouble heating these boards up.  When run continuously around 3kW, the board has never peaked above a 20C ambient rise (still air).

Loaded Thermals:


Again, the supplies are my biggest heat concern now:


There are always issues of shorting these 4kW variants when two supplies are employed.  I am afraid of sealing in the connectors with silicone/epoxy since it harms the thermal performance of the boards, so I am also coating the connector terminations on this board. 

Again, to be verified by blacklight for a proper vacuum seal..



These have been deploying quite well in my miners and a few other people on the forums.  If anyone else is interested in using these, I have also been experimenting with manufacturing and sourcing to minimize pricing.  So far, making the 2k boards in the 1000s is fairly trivial.  The 4ks are difficult to source and build at the moment, but still possible to supply in moderate quantities.  Feel free to bug me at www.price-technology.com or on these forums if you are interested.  I do realize that the forums and my website sometimes make things difficult, so I will be loading boards onto Amazon as supply/demand allows.  I am US based, but DHL has swung me a deal that is making international customs much simpler. 

Any funds received from these pet projects, will be used to fuel updates and other pieces of hardware to be used on mining technologies.  I would also love to answer any questions on this thread.

PS - a 2880 board is in the shop preparing for a production run.  I will post on this soon.

Nice improvements.  I am looking forward to using the 2880 boards.

my 2k and 4k from you work well.

Phil,

Awesome, though I think you may be one of the people who would benefit from the new coating given your past.  I dont suppose you have any power consumption numbers vs hash rate?

I am waiting for some parts to arrive and by friday or sat.

 I plan to spend 3 to 5 hours in the solar array loft.

 Tweaking and setting up some gear.  I look to use some of sidehacks  kit to allow me to use a dps-2500 to run 4 gpus. along with   an s9.

I will use a 2k kit from you.

Cool.  Let me know how it goes.  The older variants do well.  I am curious how they stack up against the new version.  Do you have any tools for power analysis?  4-wire would be pretty cool.  I am working on updating some infrastructure for that to get exact comparisons.

been waiting for new boards i guess i got lost trying to keep track . been watching the store no stock for some time so i lost hope.

hey opt how you doing .

Toptek,

I currently have stock of the 2ks.  Are you checking the right place?  I had to do some "corporate restructuring".  The website I am using now is www.price-technology.com.  I pulled down the web store because shipping was becoming quite complex.  If you need something, just message me. 

The 2ks, 4ks, and 2880s are done and in manufacture.  I will be posting a write-up on the 2880s when I catch a break.

Lead times vary based on order.  We have manufacturing down pat, but the connectors on the server supplies are becoming increasingly rare.

2ks and 2880s are around 3-4 week lead time (if quantities are reasonable) and the 4ks are at 8 weeks (the connector is in another manufacture cycle).

Just message me or E-mail me on the website if you have any inquiries.

Good hearing from you.

[takagari]

I am waiting on finsky to get in more stock, will he have these new 4k boards soon as well?
I'm looking to put up a 8k setup, so the newer boards are very interesting

Love your product, always a treat not having to solder my own cables and boards, saves me a lot of time and cursing.
Although I trust my skills, when dealing with these kinds of draws, properly built boards always make me feel better than homemade setups.

Yes, of course.  I don't think Finksy has any of my boards, I have been selling them here and on my website.

I have 50 boards assembled, but am missing some connectors.  They are due on 1/7/2017.  I should have all 50 of the 4ks ready by then.

I believe that the fact you replicated the boards I designed in the first place is what caused takagari's confusion.

Ah, I was wondering when I would hear from you.  You may be slightly incorrect with the word replicated.  I tried some of those boards and they didn't work out for me.

I am a professional engineer by trade.  Necessity invented these boards when I starting seeing burnouts.



I designed these from the ground up using what I know so that I would have safe products to use.  Supplying to the community is necessary at this point.  The thermal characteristics are proof enough of this design taking nothing after yours.

I am always here if you have any questions,

Now that my health seems stabilized, even if my left eye is still almost useless at the moment, I can come back on a computer screen.

The funny thing, is that I can't remember getting a single message from you regarding your issues with my hardware.

My customers will probably confirm that I've always been open to any suggestion to improve my stuff.
Except for the past few month, obviously.

[takagari]

This makes sense, got guys confused, I've used much of Jabber's hardware, without ever an issue.

[Optimizer]

Well, I am glad you got your health back, but if you haven't had an issues, you may have not been paying attention.  How do you test your boards? 

I sourced online via HBC.

[philipma1957]

Okay  Stop fighting guys.

I have tested and used both products both are good.


The 4k and the 2k. From both sellers.

Optimizer's  are more expensive and are more beefy then j4bberwock.

He improved  the design,  but it costs more.

I do not want to get in to this and be a referee.

But  these boards from both builders can use the

 dps - 1600
 dps - 2000
 dps - 2500

both the 2k and the 4k  can do the psus above.

If you have two  dps -2500 psu's  running 2 s9's with a 4k board  the design from Optimizer is a better choice.

Why do I say this  here is why  2 s7's or 2  s9's  will pull about  2400 to 2800 watts.

If one psu fails which they do fail  1 dps 2500 psu left  will be able to run  the 2 s9's pretty long time maybe even indefinitely .

I did this test   and the result was optimizer and j4bberwock 4k boards both ran the two s9's but after a few days a few of j4bberwock's jacks near the connection to the psu darkened.

Now mind you  this is a good stress test as it is beyond the design of j4bberwock's 4k board.

his board is a 4k board not a 4.8k board.  But many of us use the dps 2500 psu since it is 91 or 92 % while the dps 2000 psu is 87 or 88% efficient .

Optimizer has his 4k designed to protect if a psu dies and he has more copper in the board  so you pay more.

Is it worth it? It most certainly is if you are running 2 s9s on one 4k board with dps 2500 psus.

@j4bberwock  you had the first 4k board I still use your board  along with some of your 2k boards.

Optimizer simply improved on your design.  Yeah he is now a rival  and we all would want to be like bitmaintech has been with the s9  no compertition  is nice.

To everyone reading.

 j4bberwock + Finksy have both been good to me

Optimizer has been good to me.

Optimizer has a beefier product that costs more then j4bberwock + Finksy product.

There is no question Optimizer has the better product and if price were equal choice would be easy  buy his.

Price is not equal so  I can show some cases where the cheaper product is practical.

I guess I need both camps to be mad at me to be fair and I want to be fair.

I can go back and show more then 1 photo of browne/melted j4bberwock boards and as of today I do not know of any photos of brown or melted optimizer boards.  

To be fair every j4bberwock board that I know of that browned or melted was on loads over 200 watts per jack. Or on the 4k board running 1 working dps 2500 psu not 2 .

@ j4bberwock

  I have had cataract surgery in both eyes.  
One at age 52 the other at age 55.
They work well for far.
They work well for medium.
They need reading glasses for close up.

I hope your eyes get better.
