Mining Motherboards

Picked up another dirt cheap boot drive at Microcenter today.
250GB WinnDixie spinning rustfurbs $9.99, of no special sale.
Go looking for drive in a box, you at the wrong shelf. Bag only.
Ask somebody if you can't figure where they hide them...

My $120 1600W from Hong Kong's Shantou Wansen
Power Technology is now in the passenger seat of my
truck.Got here on Friday, but I had to cross town to go
pick it up. Someone always home where I had it sent...

Crazy, cause it was the second to last item to ship,
but the first to get here. And less than a week from
the sale on 11/11. I dunno what they paid DHL, but
I wasn't charged a dime, and not a scratch on it...

Came with US power cord and stickered for 110V
or 220V, which I will photo on the morrow. I don't
have any reason to believe its internally different
from version shown on Ali with just a 220V sticker.

The free US cord doesn't look up to 15A, which
both the sticker and math say should be needed.
I would guess this to be a 10A cord at best. May
be suitable for passing 220V at reduced Amps.

Appears to have cheezier fans than advertized.
Ali showed Deltas, but these are something else...
Not saying its a problem, just that its really hard to
geuss what you are buying from some of those ads.

The box is huge, but the supply inside appears to
be of standard size. Some of that extra space is
taken up by two added 80mm exhaust fans.

I havn't plugged in or measured anything yet.
Need to figure how best to attach 120A Agilent
loadbox without setting fire by pulling too much
current through too few wires.

Depending how busy is work, I might not find
time for anything more than photographs this
week. None of the other junk has yet arrived.

I am still waiting the manufacturer's response (if ever).

They advertised double ball fans, adv example appeared
Delta style if not Delta. One reviewer already complained
of very loud fans. That was exactly what I wanted.

But all three of mine are very clearly stickered "SLEEVE
BEARING". Quiet, and not moving much in the way of air.

Hasn't failed in any way yet, though not yet under full
load. As sleeves usually don't live very long in certain
orientations, I am disappointed. But $119 for 1600W?
I might have bought full knowing I'd have to void the
warranty to replace crappy fans. Why this absurd bait
and switch? CAI NAIO BITE my shiny metal ass.

Knew going in, buying Ali going to be an adventure.
Six other items are still "sorting" in China, whatever
the heck that means. Onda seems to have made it
onto a plane if I am reading this right...

-----------------

Rosewill has a new mining case at reasonable price.
Probably go up after it accumulates some reviews.
I'm on the fence if I really want to bother with cases.

https://www.newegg.com/Product/Product.aspx?Item=N82E16811147282

I suspect the row of 80mm fans in back swing down
a hinge, though nothing at the Egg clearly shows it.
Just thinking I've seen this same case before in bare
unpainted metal, don't remember where...

----

That case got bad reviews and marked down to $99.
No room for tall card or power wire on top of card is
a pretty serious flaw, I wouldn't know how to correct
except to leave the lid open...

Two other flaws could maybe be worked around. The
obstructive shelf could be replaced by sticks of wood.
80mm's relocated to the outside to make room for
dummy HDMI plugs, if you happen to need plugs...

Some of my items are now tracable to Miami.
Wait, whay MIAMI???? From China to Texas?
Like that forbidden triangle of land between
Forney and Decatur, they call Forneycatur...

Colorful price drop from $250 to $161 on Ali.
Not one of the eight sellers I ordered from...
https://www.aliexpress.com/item/COL...-BTC-ETH-Blackchain-Antminer/32834821844.html

I finally got response regarding those sleeve
bearing fans were advertised as double ball.
Chen Muxin, "Sorry Dear."

That was two words more than the last,
which said something like "Dear NA"

Now I go forward with pics and review as-is...

Not gonna lie, I like where this thread is going.
 
What the hell, I requested a quote.

Anyone have any experience with those power supplies?
 
MACASE factory seems to be in Shenzhen. Appear to make cases and assemblies.
Do they also make power supplies? I don't know. They don't make D8P motherboard.
Probably stuff whatever is cost effective from the nearest factory that churns them.

Shentou Wansen Power Technology is also in Shenzhen, they for sure made my supply.
Advertizing 1600W "Double Ball Triple Fan" for $119, shown with Deltas. And you can
see about how seriously Wansen takes their own specifications given in English.

The board inside looks to be very neatly assembled, someone really did try to make a
decent supply. Its just fan specifications are nonsense and seller reply is "Sorry Dear."
1000W-1800W, same guts inside. Only with different cables, fan openings, and sticker.
You will take whatever they glop on your plate, and be happy that you were fed at all.

I am connecting dots that may not be connected.

And where the hell is my ONDA board? "Sorting", "despach", meaningless tracking...
Don't be caught with pants around ankles "Brushing BIOS."

Use a wire rack and a box fan. Why bother with a big hot case in the first place?

Why? For lame excuse to show grainy sword photo.

Using 3 Asrock H110 BTC Pro+ at the moment.

2 are NVidia, 1 is AMD.

All the boards are hosting 8 GPUs each in Win10 x64.

No issues with cards not being recognized, installing, or hashing. Quite nice i'll say. :D

For the record, the Asrock X370 Taichi has had no problems recognizing 7 Nvidia GPUs either.
 
That all in one is not that great a price:

Biostar tb250btc-pro =$120
Two gold rated 850 watt PSUs = $160
12 pci-e risers = $80
4GB Ram = $40 (I’d do 8GB personally)
Celeron = $40 (I’d do a Pentium personally)
64GB SSD = $40 (I’d do a 120GB personally)
Wire rack = $30 (fits three rigs)

$510


+ the above build is NOT Chinese no name crap PSU, MB, RAM, and unknown CPU.

Got a quote back for $585 on the MACASE 4W7. Price appears to be without shipping, though, so I asked for a price on that as well.

CPU is a Bay Trail J1800.

Slickdeals.net for PSU deals
Easy to get a 850 watt for $80ish
Just set up an alert on PSU.

https://slickdeals.net/newsearch.php?q=gold+psu

Newegg has the Biostar board for $120 the last time I bought it. It’s $144 at Amazon right now.

You can also buy the ASUS b250 mining extreme 19 GPU for $150 at Amazon or Newegg — I did last week.

Sales come and go every few days if you are like me and like to save $10 or $20 bucks on things.

And I agree 99%, just collecting information to be sure we aren't missing anything.
I've had nothing but overheat problems with Rosewill mining coffin till I take off lid.

The whole China thing is just a lark, for experimental purposes. Most of your list is
from China anyway. Paying for local middlemen with enough buying power to get
special treatment and maybe an interpreter. Is it worth the learning curve to buy a
few items direct, learn which vendors are reasonable to work with?

Would probably change CPU to Ryzen3 on discounted B350, add UPCIE switch.
Microcenter knocks another $30 off when you buy CPU and mobo together.
They also offer refurbed WD 250GB spinning rust for $9.99.

So nothing currently.

Not in stock.

You can buy either an evga refurb 850 gold for $89 or a buy a Raidmax Vampire 850 gold for $89 Right now at Newegg and have them in two days with a free shop runner account.

If you wait a couple days and setup an alert - yes you can likely get a 850 watt PSU for$ 80 or less and the slickdeals link above shows that to be the case.

That’s the methodology I use. Set an alert at slickdeals and watch my email.

FWIW - That no name machine from China isnt going to get here in two days either.

But

No skin off my nose. Buy that Chinese all in one contraption if you like adventure and likely headaches. (What drivers are you going to use? What support model? What if you have to RMA). No way I’d touch that thing for the same price as legitimate name brand available parts in the US (reliably delivered this week) — which is all I’m trying to point out. But to each his own.

I am starting to despise risers.My first few orders of risers were 100%, but I now have a small pile of bad or intermittent risers now. Becomes very time consuming with the intermittent ones trying to figure out which card randomly vanishes, and why.

Looking forward to getting my Onda D1800 setup and tested.

Bay Trail takes DDR3L, and don't fit any socket.
Can't be same version D8P board pictured in ad.
Or they got D8P specs all mixed up with D1800.
Whatever they glop for you today, its lunch...

Yup, you're right. I looked again. That was for the 6-GPU 4W5 that comes with the Onda D1800 BTC. CPU is shown as included but not specified for the D8P versions.
 
My whole point: Translator who writes the ad has no clue what the company might actually ship.

ONDA D8P specifications have changed again (V2.0) , not sure if 12GPU is still supported...

Silkscreen by memory socket sais DDR3.
What exactly is the header labeled LPCI there for?
External PCIE expansion switch? Just grasping at straws...
Maybe its LPC 1? Low Pin Count bus for brushing BIOS?

No clue who is making these, or model number, but I find at least two resellers. Link for you the evil of two lessers.
Appears you might select cable length 1M to choose only the mobo. Select 5M to choose a mobo with eight risers.
https://www.aliexpress.com/item/B85...ots-Mainboard-for-Intel-XXM8/32845355701.html

Don't know why UPCIE are on the side instead of the front, almost what I've been asking for.
But why socket 1150 with DDR3? Brand might be "Etmakit", same as 4way riser seen before.
I can't find any direct factory store by that name, so don't take my guesswork as fact...

Soyo and Epox exist in name only. Some companies bought the assets of the defunct originals and reused their names to manufacture parts for the Chinese market.

As for why B85 and DDR3, because it's much cheaper than the 100 series and DDR4 and has no loss of performance for mining.
 
Mine isn't working either. Cause its still "sorting" in Shenzhen.

Dual MOSFET risers supposedly arrived, have to go pick up.
Of eight orders placed on 11/11, only five have arrived so far.
Aside from Onda, still waiting 220V power meter, and switch...

Tracking reveals a pattern of delay depending on location.
Do well to note from where in China you might order.
HongKong=Fast, Shenzhen=Donkey+Slowboat

But wait??? Supply that got here fast from HongKong was
ordered from a factory in Shenzhen. Completely confused.
Junk may not always ship from where factory claims to be.
