it was noted here on a multiple occasions (first by fullzero, I believe).
dmwardjr had a post on why it is possible (something to do with electrical properties of materials at different temperatures).
From a historical perspective, not a surprise since Jupiters had the same shtick.
People even plugged openings in the boxes.

The sweet spot for me balancing hw errors and th/s is around 53, which goes against everything I know about electronics. The rev 1.4 boards I have are perfect at 51, the rev 1.5 boards are perfect at around 52 and the 1.6's are perfect at 53. I will dig for those threads since those temps will likely (?) not be good for longevity. Naturally, I can only get around those temps by observations since I use CFM since I live in Texas, but color me concerned balancing short term profitability and longevity.

I will dig for those threads.


Thanks,

Hi, does anybody knows how to stop beep sound when connection to net is down? I cannot find any controler of "beep sound" like S4 had. Thanks for any advice.
I don't think the S7's have a speaker to notify you when the internet connection goes down. I may be wrong but I though that's how they designed them.

I have two now .. both of them beeps like a hell Smiley ..so it does

I pulled the buzzer off on mine, and if you're careful it may actually be replaceable as the pins also come out. You'll likely void your warranty etc etc.

I have been running my nine b1's for roughly twenty days and have been adjusting the temps to find variance over week sample sizes. If I run them between 40-50 I get an average of 43.10 th/s, but if I run them between 50-58 I get around 44.37 th/s. Seems like an odd correlation, am I high, not in the temperature sense?

I'm with user100000 regarding "speculation."  He's located on tradingview.com.  Here's a link to his "space" on trading view:  https://www.tradingview.com/u/user100000/

Thanks for that url, I never bookmarked it from a thread a longtime ago. Smiley

You're welcome.

This could be the beginning of historical wave 3.  IF it is historical wave 3, it is usually the biggest wave of 5 historical waves.  Each wave normally takes several years.  So, historical wave 3 will last at least to 2018, if not 2021.  We can see Historical wave 3 top out anywhere from $30,000 to $250,000; depending on how many years it lasts.

nice summary. honestly, i looked at trading view and got lost in graphs. i agree that it is wave 3.

Bought a S7 from Batch 5 I have two EVGA Supernova G2 1300 watt PSU's I want to use with it the question is The S5 when using one PSU only measures 11.88v on the PCI-E Connectors when Under full load "HASHING" no overclock does anybody think if I use two PSU's on the S7 will it give me a problem ?

Question 2: what does the S7 do when it don't get enough voltage does it BURN UP like the S5 ?

Question 3: Are there any 1500 watt 12vdc to 15vdc variable output server PSU's out there if so what's the link ?



this one goes from 10 to 13.5

I have been using it here and there.  A guy on ebay was selling them at a good price

Hmm that PSU is 87% efficient.

But S5s "burned up" if you ran them with too low of volts?  Interesting.

I have my old Rosewill Lightning 1300W PSU running my 4.66TH S7, seems to be doing fine even though I only have a dedicated 20A 120V circuit.  PSU outputs 12.18V under full S7 load!

The S7s make some real noise when the internet goes down, not sure where it comes from but it definitely does it..

On s3's I used to install a tiny screw in the piezo beeper.

Did anyone get the following error on their order when trying to confirm it.?
Can not buy different currency once.

That is with either payment options. Angry

I think it is unfair. Just because our president can't count does not mean the rest of us can't either.

Had the same issue, just split your orders up. One for miners another for the PSU.

They are using less chips per board.

Thanks.  I didn't notice that the first time I looked at it.  I was about to pull the trigger last night on a Batch 5 and I told myself I'd wait until morning.  Now I'm kicking myself for not ordering it last night for a little over 4BTC.  Oh well.

Batch 4 and 5 are sold out.

lasted just a couple of days.
anyway, my B4 order finally 'turned green'.

Interestingly, S7 batch 6 went from 162 to 145 chips (144? as 145 cannot be divided by 3-weird)

This contains an error, they put 45 chips per hasboard, total 135 chips, not 145:

batch 1, 3 and 5: 4860 / 162 = 30 (total hashpower / number of chips = hashpower per chip)
batch 6: 4050 / 30 = 135 (total hashpower / hashpower per chip = number of chips)

So, they went from 54 chips per hashboard to 45 chips per hashboard.

Now it is easilly to found a PSU, but it is still too high...  Sad

Well the maths works for 135 Chips . The only snag is that with 45 chips / Board the only maths that works is 15 Nodes of 3 Chips, one less node than with 144 Chips and that would mean that the Core Voltage with a 12V Supply would be even higher. 12V / 15 = 0.8V and that is way too high. That is if the BM1385 Data Sheet is to be believed?

Rich



And whats the deal? Its the same price, or even higher than the "lesser batches" for less hashrate. What is this, the "Lays marketing trick" where they just sell less chips per bag but use the same price to milk more money off customers?

They must have implemented something on the board to regulate down the Voltage to the 0.6X range, why go through all this trouble? I don't get it and its bothering me, mostly because i was thinking on picking up one soon, i guess.

This is not what i had in mind when the rumours of the "S7 mini" started going around...

Well it's all a bit of a mess.  Smiley The original "Leak" with 3.5ish TH which would have been possible with a 2 Board S7 made a lot of sense.

Now Bitmain tell us it's got 145 chips which does not work. So we guess 144 Chips which can work, the core voltage increases, which is plausible given the problems they have been fixing by lowering the frequency.

Another bit of maths suggests it might be 135 Chips, again the maths work but core voltage is now up to 0.8V which according to the data sheet particularly given that the PSU spec now goes to 13V is definitely too high.

The pictures all still just show the original S7 Hash boards with 54 Chips so that does not help. So I guess we are just going to have to wait, unless someone from Bitmain want's to put us out of our misery?
