ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

It's another way for bitmain to save pennies.

Got a batch 8 in today, disappointed with it. Only runs at 4.6Th/s.

hows the power consumption? can you confirm the control board has removed connections? thanks

Didn't have time to get measurements for power use yet. Yes, control board is missing 6 data ports and 4 fan headers.

Notice the very high hardware errors at stock settings. bitmain is selling us cheapened out to the max, overclocked junk.

Thanks, bitmain.  

wow are you running it in a really cold room ?  Heres what I noticed, put fan speed on manual, and play around with it.  I went from 4500ghs to 4700ghs depending on which fan speed setting I have.  soft reset until you get it, and then dont touch it.

edit:  your hw rate is too high.  you must bring those temps up a bit, or play around with fan speed.  I run at 35%, 3000-3120 rpm, its 4700ghs and 58 to 60 temperature.  I had bad ghs before and same hw rate as you.  now its 0.0032%.

You really surprised that this highly reputable, reliable and HONEST company would do such things???

  **SARCASM OFF**

They still haven't done anything with the people they actually OWE money to due to the Batch1 fiasco.

Hi Prelude,

I did notice that was only 35 minutes of mining.  I'm assuming you have reboot the rig from the system menu after startup and configuring the pools?  I've found earlier batches I have had to be reboot sometimes a couple of times before getting stated hash rate.  I know you have mined a long time, Sir.  I'm just curious if you had already done those things?

EDIT:  I also noticed the HWE's [While not high] are higher than a lot of other rigs I have at 0.0012 to 0.0089 for many of my rigs.  My HWE's would be about where yours is now but lower after a reboot from system menu.

anyone know how much Watts B8 would take if underclocked at 650 Mhz ?

W goes up and down about 10W numbers are from middle.

With BM power:

700Mhz 1210W
693Mhz  1103W
675Mhz  1170W
650Mhz  1130W
625Mhz  1086W
600Mhz  1040W

interesting...you must have a very good specimen+great PSU since
Bitmain claims 1293W+10% at the wall at 700mhz with 93% effective PSU.
My B6 (same number of chips) did 1160W at the wall at 650 with gold PSU (don't know how effective it is)

The cleanliness of the power from the power company along with the quality of the PSU makes a big difference in the actual wattage.

[disclaimer201]

I bought the APW3-12-1600 PSU and the antminer S7.

I connected the PSU to the wall and that powered on just fine. The fan came on and it seems to be ok.

I then connected all 9 connections to the 3 hashing boards, as stated in the instructions which came with the S7, but nothing happened on the miner. No lights or no fans turning.

I tried connecting the last connection to the control board and that didn't do anything either.

I tried powering off the PSU with everything left connected and plugged back in and nothing.

So I started to look for a power switch on the unit and I looked at some pictures online and realized the button which I believe is the power button was pushed all the way in and stuck behind the metal plate which is right next to the QC sticker and Ethernet port.

I used a small nail to pry the button out from behind the metal, and that worked, and if I push the button I can feel a click, but the unit still doesn't turn on. I tried the same with the control board PCI-e connector disconnected and plugged it in after and still nothing.

I held down the button I freed up for over 10 seconds and nothing.


Anyone have any hints / tips for me?

A very silly idea, but did you use a cable connector to "short" your PSU into knowing it is supposed to turn on? PSUs are usually built for computer mainboards and won't turn on unless a computer is connected or pins 4 and 6 (I think) are connected.

Wall sounds like 120v
Need at least 208v
No jumper on bitmain psu, just apply input power

Woolfen, is correct.  The APW 12 1600 is a BITMAIN PSU.  It does not need a short to fool the PSU for 12.0 volts.

It sounds more like they may not have plugged a PCIe cord in the controller OR they had the PSU running before plugging in the PCIe cords and may have burned up the unit.  The instructions provided by BITMAIN can be misleading for someone new to mining.  

EDIT:  This is assuming they are plugged into 208 to 240 volts of course.

Need to hit the forum before tweaking stuff. Lot of very bright guys here.

if the psu was running and you hot plugged live pcie cables into the boards and into the controller there is a huge chance you fried the gear.

NEVER NEVER NEVER NEVER NEVER PLUG IN HOT PCIE JACKS TO PCIE PLUGS

or maybe you have 120  volts and the psu does not work correctly.





If you have 240 volts turn off everything unplug the psu from the wall. i also  mean turn the power off via the correct circuit breaker .

but leave all ten pcie cables connected wait two hours pray to any one you want. then plug the psu into the dead wall socket.

so all pcie cables are plugges in.
your ethernet cord is plugged in
the psu power cord is plugged into the wall.


go to your circuit panel and flip the breaker on  wait a few minutes and see if it works


good luck!

You can connect APW3 wrong way to controller if You are not carefull, connectors are shit. Dimple on the side for the hook is very small and without any force You can connect power wrong way. Plastic parts on connectors shouldn't fit wrong way they are oriented. Controller don't break on reverse polarity, "tested" in dark garage.
High quality connectors which I have used on my own soldered wire looms don't fit wrong way to S1 or S7, I tested it while writing this post.

SAVE some cents on production and loose a lot of $ when using the product!

Also APW3-12-1600 manual on BM support is not for APWs which they are sending out, small connectors are different!

I'm still thinking that these products are not very matured for they price.

[padrino]

The PSUs are quite profitable for them, not very high quality but it helps capture more revenue and profit per unit given the convenience for buyers of S7s

I don't know why you mention that the PSU is not very high quality.
IMO The PSU is v+good quality, on par with quality of Seasonic 80PLUS gold PSUs.
For e.g. they use top notch Nippon Chemicon high temperature capacitors, the cooling fan is a Delta part, etc.
What they have skimped on is features for home miners, like foolproof PCI-E plugs, adjustable fan speed, 110V input, power switch. These PSUs are not noob friendly, but for the seasoned miner who knows their stuff.

Brought the temps up by lowering the fan speeds, and quite a few restarts brought me to this:



Doesn't seem to get any better. Guess I have a lemon.

I reallllllly doubt they are anywhere near the level Seasonic are at. We're talking about bitmain here.... And comparing them to one of the top dogs in the PSU industry.

The 1600w bitmain PSUs aren't bad, for sure, but we haven't had a proper review of them. We have no clue what the regulation or ripple numbers are. I wish bitmain would send a sample in to jonnyguru.

[p3yot33at3r]

That will never happen - jonnyguru would tear them to sheds

anyone need S7 hashboard connector pin info description, i can provide it.
also you can use hashboards only 4 data cable (tx-rx-3.3V-Gnd)

Interesting, please share the pin out. Are you sure that it's only 4 connections? If the same as an S5 I would have thought there would also be a Reset plus Data & Clock for the LM75A Temp Sensor?


Rich

if you use 3 boards with 1 controller i think 1 lm75 connection is fine. i prefer to use center board lm75 i2c connections.
for others you can use only 4 cable.
but this is meanless if you use 3 board and 1 controller. this pin info for more than 6 hashboards like s5+, also for short wires.

Not sure why you are messing with the connectors? But I disagree, as far as I know the firmware looks at all 3 LM75 and takes the highest temperature to set the fan speed, so you are chancing that the centre board has the highest temperature, which it may have but why chance it?

i know Rich, i can share this for nothing. this is for only knowledge if you want
i inspect that for misterious pins like command-reset-test pins.

Edited: Also i share Fan connector info and modify, and you can use any PWM controlled fan with that. but be patient please.
