any news on the 4k boards?

bitmaintech will be selling batch 10  I think I am getting at least 1 more s-9

I can use a 4k kit.  I have psu's waiting.

So far your two 2k boards are flawless and the power drop is very small on board and cables even with heatwave of Seven 90f+ days.

Definitely - sidehack is an exceptional asset to the community, really thankful he's around. 

Unfortunately those aren't cards you escrowed for me - you did the RX480's for me, and I wish I had 6 of them to put in a rig.    Right now all of my systems are R9 390's, I picked up the RX480's to play with and use with my Oculus Rift, so not all business. 

sidehack has made some good one for me.

How are the cards I escrowed for you?

are they in that build?

heheh, sidehack's saying that because he's making my new cables for me - and don't be surprised if they aren't wrapped nice and clean just like those. 

Yeah  he needs these cables.


They are 3 foot long look like 16 gauge and have a nice wrap.


All kidding aside  a very nice build

Can't wait to see it with cleaner cabling.

Thanks!  You really can't appreciate the case from that angle - here's a better shot:



I'm pretty close with the design of the case, the one with the amp meters was my v1, this picture is the v2, and I'm finalizing the v3 right now, which will probably be the final design.  It's certainly more expensive than the open-air cases, but it also controls airflow in a radically better way, plus they're completely stackable and can be docked to a plenum like nobodies business.  In the latest version I'm incorporating air straightening and entrainment, which means I'm using 100% of the air where I want it, plus I should be able to achieving system CFM higher than just the fans alone are capable of.

Once it's all nailed down I'll probably make a thread about it's construction and features, for those interested...

Mark, your work with acrylic never ceases to amaze. Well done

I may pick a few up.

I can make a setup that tests  volts at the breakout board and at  s-9 input jack

use with this

  plug into the controller

I've used very similar ones in my latest build - although I ordered the ones with a current sensing not voltage:

Here's what it looks like in action (I used two of them to monitor the 12v and 5v sides of the molex connectors on my GPU build) - and I'm using the DSP-2000BB and Optimizer's board, you can see it up in the upper right.  

Speaking of power. these are -- nice. And pretty damn inexpensive.

good for 3-30VDC.

@Philipma

I will send you tracking number as soon as I finish.  It may be a week or two, but after I have a fully functional jig, we should be able to pump out higher qunatities.

Glad things are working out.

The new 4k boards are similar in form factor, though we have added a few mounting holes away from the copper to allow mounting of an in-house or third party rack.  We will be working through all of the board designs first, but if sales are there, we can develop a rack as well.

And I am glad you feel that way.

Sweet  I just scored 4 dps-2500 psu's I was going to ask about the 4k board. today.

I also picked up a few cables from  :

Itop https://bitcointalksearch.org/topic/quality-pcie-6pin-male-to-male-1-meter-cable-sold-out-1535584

my goals are to fully compare

your 2k board
your 4k board

j4bberwock's 2k board
j4bberwock's 4k board

using the dps 2500 psu's

Also will compare
your pcie cables
j4bberwock's pcie cables
and Itop's pcie cables.

So in 92 f temps and the solar array stack is 97f  your 2k boards run cooler then j4bberwock's 2k board.

now to be fair to all none of the gear really pushes a psu.

my max watts is 1300 at the meter (ac) on a dps-1600 psu  using your 2k board
I also do  1300 watts at the meter (ac) on a dps-2500 psu   using your 2k board
I also do 2600 watts at the the meter (ac) on a j4bberwock  4k board and 2 dps 2000 psu's
and lastly 1300 watts at the meter (ac) on a j4bberwock 2k board and 1 dps=2000 psu.

on none server psus I do 1200 watts at the meter with a evga 1600 p2 osu.

plain and simple  your pcie cables j4bberwocks cables and Itops cables all seem close enough

But I get better numbers head to head with your board against j4bberwocks.
I drop less voltage and I run cooler.

you can get in to arguments as to which is more cost effective since his is cheaper, but I no longer recommend his for avalon 6's as I have darkened my 4k board and my 2880 board running avalon 6's on j4bberwock boards.
Basically I estimate your boards can do 25 watts more per jack then his boards can do.

I have these 4 psu's waiting for some 4k  boards from you.  they came today

Is your 4k board going to be a similar configuration to Jabberwock's board (ie; two PSU's back to back)?  And are you going to have some sort of mounting bracket available?  I don't know if it will matter much for me, as I'm mounting it in a custom case, but if it's available it might be worth considering.

Love your DPS-2000BB boards, BTW - so much higher quality than the other ones I used that I've basically phased out all the others and just use yours exclusively.  Looking forward to the 4k.

Phil,

How goes testing?  I have finally straightened out part of manufacturing for the 4ks.  My initial testing looks promising.  I will be sending one of these to you as soon as I polish everything off and trust the design.  So far, current sharing looks good and balanced between both supplies around 2500W.

   yeah it would be good to have it.

I can not turn on side since the psu needs  to be cooled . I have some rubber that will do.

the low power loss is very impressive 12.20 volts at junction to 12.11  volts at s-9 pcie jacks.   

It looks like I should place some 6-32 holes on the board for standoff.  I hate to see it hang like that.  On the next rev, I will provide an update!

Yeah just did some sound readings.

1 meter = 69 db with 50% fan speed  but it is not the nasty screamer it is at 90%

2 meter = 65 db


6 meters I am at the entrance to my den  it is 54 db


11 meters I am sitting on the couch in the den ready to watch the HT it is 44db


I was able to get the s-7 as low as 39db on my couch but I had more sound proofing .

Since these are going to the solar array I am happy with the 44db at the couch.

Did you find your sound meter?  I would like to know how loud it is at 50% fans.
