There is different firmware for some frequencies though. I think that is what he is talking about.

Take a look at bitmain S7 firmwares: https://bitmaintech.com/support.htm?pid=00720151023101739550pOBiK5sO06A0

Yes I had seen that. I wonder if they are essentially the same with the exception of which freq is default. My batch 5 came with the latest firmware on it.

do you need new firmware for the 625mhz?

No it's configurable since way back on the S3. Those are the options on the dropdown list in the web gui.

Batch 5. Not too shabby.

showing ~5th at 625mhz

do you need new firmware for the 625mhz?

no, but doing this is negating the warranty, strictly speaking.

Very interesting and not what I had expected. They have got rid of the bottom 9 chips in the chain, as opposed to 9 out of the middle I had predicted. What I do not understand is what and why that additional component (Large Inductor?) and the additional capacitors are for? Unless perhaps there is a buck converter chip on the other side of the board & we have moved away from the string design? Need a Sidehack opinion here?

Or perhaps it's a hybrid with a buck converter to a slightly lower, Adjustable?

voltage & then still a string for the chips?

Also a picture of the other side of the board would be great?

In some cases, inductors are installed to offset the affects of capacitance. Especially, when high frequencies are involved. Those round components near the inductor looks like capacitors. It has me curious as well.

Thanks, very interesting...
You probably meant 135/3=45 chip blade.
I would love to have 135 chip blade instead Grin

Good luck trying to keep that cool...

i still calc roi using : current diff + 50% current diff

market won't be dead yet . . . still many have high hopes. miners will be sold out when btc moves. 1 of the main issue is that s7 are still pre-orders, bmt might be doing some r&d + testing while the btc are being sent to them.

s7 is a pretty neat miner besides the 9+1 pcie's .... just my 2 cents

i'm gonna post this again, to those who have "merged" 2 in 1 s7 using single controller, withouth changing any settings, have you noticed that the hashrate is lower than 1 single controller ?

Is decreased, but not significantly.
I use only the very best miners in pairs.

Some of them are working at a frequency 625 (from batch 3)
2d17h GH/S(avg) 10,063.61
1d21h GH/S(avg) 10,107.83

Speed is more dependent on the ambient temperature and the PSU.

Waiting for the current six miners.

ANTMINER S7 BATCH 5 × 2
Batch 5 scheduled shipping date is in Nov. 23~Dec. 3.
ANTMINER S7 BATCH 6 × 2
Batch 6 scheduled shipping date is in Dec. 7~Dec. 17.
ANTMINER S7 BATCH 7 × 2
Batch 7 scheduled shipping date is in Dec. 7~17.

I think that they have been built and is currently being tested.

thx for the answer !!!

i've already received my batch 5 ... u haven't ? i was really surprised they shipped out early.

did you upgrade your FW to latest ?

just DL the tar.gz file then flash direct ? have to unpack ?

all of my s7's, batch 3 & 5 comes with sep 15 fw

Does anyone else think that Bitmain may have oversold these S7 units. By oversold I mean selling so many units that the diff will go up by stupid amounts, killing their ability to sell more batches of S7s pretty soon. At least at the current price that is. I'll admit that I contributed to this problem by jumping in at batch 1 and again at batch 3. For some stupid reason I thought that the diff would stay under 5% per jump as my ROI calculation.

Between the S7 and Avalon 6 (not to mention Bitfury's new miners in its 100 million dollar mine that's now coming online) I think the market might be dead soon. I see that batch 8 has been up for a while and I have a feeling that it may not even sell out if we get the kind of jumps that have happened in the last day or two again when the next few batches actually ship out. Avalon 6s are just starting to come online this week. Most sold on the secondary market are just arriving or in transit to customers right now.

"For sure my wife would not let me keep the S7 with that annoying loud howling sound so I had to come up with a solution."

Unless you go watercooled the S7 is not a good idea for home miners, imo. Seriously, what are you guys thinking with your homemade tubes and extensions, they are a serious fire hazard. Let alone the noise pollution.

The extreme heat these monsters are releasing have marked a red line for me. The chance something is burning or melting, as demonstrated with pictures in other threads, is warning sign enough that home mining has reached a limit. And 1200 watt PSUs, do they even last for more than a year 24/7? They are also damn expensive.

Designwise, I don't like the entire single heatsinks on the back of the S7- many have reported them to be falling off. Back in the days of gpu mining you were better off with an AMD 5870 than 5970 too. It was just too much of a hassle to get them cooled and running smoothly. The 5970s often died prematurely, no wonder.

Until something has improved, the S5s are probably as high as I will go until the (final) end of home mining in August 2016.

I'm probably in the same boat. I find it hard to realize people are running these in a home. The noise alone would prohibit to run S7's in an apartment/condo at least in my state (NJ). I'd have my neighbors banging on the door at 10pm. Even after replacing my jet blasters (original S5 fans) with quieter fans I still hear that hummmmmmm throughout my house, regardless of which room I'm in. I do live in ranch style house, which is not a good scenario since internal walls do not have insulation. I did insulate with noise dampening insulation on the cheap. All my S5's are in one room with a single window air conditioner. Even when it is almost 50 degrees out (at night) and 60 degrees (in day) the S5 temps will increase to over 60-62, which I don't like to do. I do admit, if the jet blasters were installed I wouldn't need worry at all. I have to give congrats to the new guys who are running these S7's in their homes. I would imagine some really creative options with trying to suppress the noise. Eventually when temps go down to 40F and below consistently I won't need to bother with the temps at all until the spring, by which time home mining for me will be over. Kind of perfect timing really. I did always want to get some 4-5 inch air duct hose and expel all the heat right out the window, but could never figure out how to build it. Don't want to invest another $1 into that setup, so all choices of changing stuff around is not in the cards.

Good luck.

At almost 1300 watts I think I'm done chasing the mining train. I may have mentioned it before, but most home outlets let you pull about 1200-1300 watts for the entire room (circuit). That means you're asking your ancient home wiring to pull 100% for 24/7 mining. Fires are a real possibility once you get in this range. Imagine all the 17 yr old kids that have a few BTC, order a S7, and plug it into their mom's basement unknowingly overloading the circuit like a Christmas tree with too many lights. Spark, spark, and two huge fans to kick the flame up. Now you're looking at a home burning down and possible lawsuits, though with BM being in China a successful suit is unlikely.

I'd never run something like these S7's in my home UNLESS proper wiring gauge and sufficient volts/amps. If you have a family and children at home I would be thinking about their safety before heating up electric lines in the walls and heating up that junction box. 1000+ watt heaters running 24/7 should take special consideration. Just be safe and good luck!!

I just put in a 20amp breaker in the breaker box, ran a 12-2 wire (all 120v) about 2 feet and I have a nice 20amp plug in the garage. 1600w power supply, (evga), warranty 10 years. I wouldnt trust the bitmain psu, but hey the main reason i dont buy those server psu is the noise level. I dont see what can go wrong with the setup. even if the miner "burns", its on concrete floor, about 3-4 feet away from walls, ceiling is 8ft. Home mining will never be over as long as we get -30 celcius in winter. if you live where you need to cool your miners...well thats a different story. For example in summer it does get very hot, so when it does I just shut it off. Free heat. Some btc. Re-sell miner when the new ones come out, buy a new one. ain't going to be rich but at least I wont be cold.

My order status for batch 7-sold out is now "valid" and I got e-mail also, so resale was not a program error or something.

I got also mail that China customs demands values at invoice USD even when sale and price is in BTC. This is going to give me some hard times when I have to pay Customs fees and proof what I have paid for the mainers.

BTW this forum software was "supposed" to be updated years ago. The forum operator which I think is sitting on a few hundred thousand worth of BTC never upgraded the forum software so you'll see back to back posts from users "like me" who respond to what they read and then have to go back to the thread to read on. There were threads out there on how much BTC the forum operator was hoarding. Users just keep donating I guess but don't pressure the operator to update to a modern browser. I mean seriously, SMF 1.1?

EDIT: A good read. You'll read a lot of good stuff in there about updating this forum, which never took place. Why users lied outright puzzles me, but I think it was just to get more donations.

https://bitcointalksearch.org/topic/looking-for-someone-to-createmodify-software-for-this-forum-5500-btc-50617

Here's another. Looks like the forum has over 2 million USD worth of BTC. Of course we don't know the real transparency and that post was from two years ago. Slap on another few hundred thousand for donations. Just very interesting stuff. What's real funny is the topic number.

https://bitcointalksearch.org/topic/forum-funds-155000

Just want everyone to be aware. Throwing lots of money into BTC which in my opinion its value is tied to a dozen or so people. Unfortunately BTC got its good start in the drug market. Do some Googling and you'll have some good reading.

You realize you can check the progress they're making on the new forum right? I'd also like to know when you think the last donation was received. It appears you are very confused. This forum makes BTC from advertising and very little from donations.

I was looking for a status update but could not find it. I found the posts from several years ago easily though which indicated the forum had over 5000 BTC in donations so I was only basing that donations kept going. I really did think development on an updated forum ceased since it has been a few years from the original offer and we are still using the same stuff.

EDIT: I did find it. Was in the META area.
