Now, I need to find the way, how much will be daily power consumption.. :-( I have no idea

It's easy to figure out.  You know how many watts the S7 uses.  Multiply that by how many hours per day you will mine with it and divide by 1000, that is how many kilowatt hours/day you will use.  Multiply that by 30 and that's how many KWh you will use in a month.  Multiply that by your electricity rate and that's what it will cost you to run an S7 per month.  Omit the x30 step and that will give you per day cost.

For me to run one 24/7 for a month it would cost = 1.25KW * 24h * 30d * $0.30 = $270 a month.

My daily cost would be = 1.25KW * 24h * $0.30 = $9 a day. That's also why I will never own one.

Just a quick edit, but contract days per month are usually taken as 30.4. It sounds like a small difference between 30 and 30.4 but it underestimates by 5 days a year, which in this case is $45.

This hash board burning instance if the internet fails.

What is happening? Do the fans shut down when the internet is no longer sensed? If that is the case, it would not be hard to add a separate fan controller to keep the fans push/pulling air across the boards as a safety precaution while or if they ( Bitmain ) even bothers to provide a fix.

I suspect if it is happening it is something hard to replicate.  I never could replicate on my S5, but some had the issue and was a pain for them.  On S5 I even without internet a few times never had a big issue.

On S7 it is kinda scary to hear people mention this problem.  I'm hoping it's a very small subset of machines.   

I'm not too bothered by this situation. My unit was in that state for about 36 hours (switch died) before I noticed. It was cold in a different part of my flat and there were no problems at the time or as a result. And as I explained in the other other other S7 thread with some maths, a lower fan speed and hotter exhaust doesn't suddenly turn it into an oven.

So just to verify, wil I be ok with 3 Corsair HX850's to power a single S7?  One PSU per blade with the third also powering the board.  I have these PSU's sitting around after selling off the 3 S5's they were powering.

You would be okay with 2 of those.  Don't need 3.  The only way you would need 3 is if the HX850 did not have a sufficient number of PCI-e connections.  I'm not familiar with how many PCI-e connections the HX850 has.  I have a lot of AX860's laying around.  They have 8 PCI-e Connections on the back of the PSU.

Make sure you use all 3 PCI-e cords on each blade because the gauge wire for the PCI-e cords provided with the HX850 PSU's are small compared to others that are custom made.  If you had custom made PCI-e cords that are 16 gauge like mine, you would be fine with 2 PCI-e cords for each blade.  That's my opinion.

I used 2 Corsair AX860 Platinum PSU's to power one S7.  It works fine.  I did have to do a soft reboot after initial power up to get it to hash at 4.8 TH/s with low HW errors.

HX850 has 6 so plenty. You can use the data table in my PSU comparison.

summer has come

people just did not tell me that by simply taking the cover off S3's that they run very cool EVEN in summer.

No extra fans, cooling or family complaining noise and heat

Please consider

Soooo..... simple

S3 is an enclosed push pull configuration so while you might be reducing temps on one point on the board, you'll likely hinder cooling overall.

Kind reminder:
When mining with S7, be sure that you've connected the internet properly and the internet is working well, otherwise, the boards may get burnt easily Sad

I would not take this seriously. This message is not from Bitmain.
They would have used proper channels, and not post a poorly written post on a forum, with an unknown username, lol!

It is a Bitmain account, Janet's successor as she is off doing other things. I've asked them to add it to the BITMAIN signature.

One thing you can say about Spondoolies, their customer service is better than all the other manufacturers combined.

We'll see if this continues now they are Zvi-less.

Of course your only insight is forum members, the large majority of sales were to operations off the forum, from what I have seen the service was still great, until spare parts were exhausted.

I'm not referring to on or off forum, I'm referring to staff. They had one sales / marketing / lots of other important stuff guy (Gadi) and one SW development / why isn't it working / super tech support guy (Zvi). When you lose one of your allstars its always a challenge to replace.

If I was going to use a power over Ethernet kit to run this do I need to think about the 1400W PSU at all? Or would something like this be fine?

PoE has no impact on your PSU choice, that one is fine. There are some other ones that have 2/4 ports or wifi repeaters if you want to future proof a bit. I use PoE and replaced my old one (which died) literally just this week.

889  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: October 25, 2015, 07:14:09 PM
little birdie says . . . between 40-43K USD . . . MOQ . . . around 15 units . . . Delivery around March 2016

So.... $377/TH with a 5 month leadtime (inc PSUs). S7 is $340/TH with a <1 month (no PSUs).

The lead time is a killer, but tit for tat the SP50 is a much better solution for large scale farms.

Yeah, only 4 months before the estimated halving.

Doesn't particularly help me as I don't have any way to automate the process after that. I have to start with words and turn words into other things as nothing I know interacts with non words.

dogie, for a rough solution you could use ImageMagick's convert to read the pixel value for each pixel:
http://apple.stackexchange.com/questions/26719/any-tool-to-tell-me-the-exact-color-value-at-a-point-on-a-png-image

the relevant part:

Quote
$ convert image.png -crop '1x1+100+200' txt:-

Outputs, e.g.

# ImageMagick pixel enumeration: 1,1,255,rgb
0,0: (236,236,236)  #ECECEC  rgb(236,236,236)

then you need to correlate the output with IP based on the mapping specified here before.

This is a pretty ugly way to do it, but it should require minimal coding, so for a one-off, it's how I'd do it.

Nice, worked perfectly. If I get bored I'll see what I can do with this although at this point I'm not actually sure Tongue

dogie, are you going to test out the S7 firmware updates and let us know the pros and cons?  I'm hearing it is giving a slight improvement and less variation in hash rates but I'm leery of upgrading until I know what they might be taking away...

Maybe although firmware is always a tricky area. People come up with the weirdest "it did x y z blew up my machine error rate up 0.00005%" things which makes it hard to tell anyone anything of value when its drowned out by anecdotes.

I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description ["low quality posts"], and perhaps I could never succeed in intelligibly doing so. But I know it when I see it...

Same applies here.
897  Other / Meta / Re: Most popular board by activity. What is it? on: October 24, 2015, 11:22:34 AM
That was my understanding of it. Ie:

I have 5480 posts in hardware
I'm 1.3666% by activity in Hardware.
Hardware has 484,894 Posts.

5480 / 0.013666 = 401,000 posts. Close enough I guess?

the Group Buys section have 83911 posts. so the Hardware section alone only have 400983 posts in total.
so yeah, close enough.

Oh that's very true, I forgot about the subforum. It was 400995 at the time so its probably accurate to the post once it updates.
898  Other / Meta / Re: Most popular board by activity. What is it? on: October 24, 2015, 10:44:53 AM
it's the number your post in a board divided by number of all posts in a board.
so if I have 1000 posts in meta and there are 100000 meta posts in total, it'll show as 0.1%.
Does all post in the board mean all the posts in the board since the forum was created? Or it only takes into account of posts made in a particular month or a time period?

since the forum was created.

oh, and if a board have a sub, the posts in the sub-board doesn't get added to its total posts.

That was my understanding of it. Ie:

I have 5480 posts in hardware
I'm 1.3666% by activity in Hardware.
Hardware has 484,894 Posts.

5480 / 0.013666 = 401,000 posts. Close enough I guess?

Question: Why restrict the modlog to only last one week's entries?
What is the harm in having a much longer (or even full) log?
this is a good idea but the modlog would take a while to load

That isn't a valid reason.

Yeah. Even if it was just dumping to a .txt it'd still be useful to reference.

The s-7 is better then the s-5 And depending on your setup there are mufflers that work.

I disagree.
To me 1 x S7 is much louder than 3 x S5's.  Even with fan speed reduction to 30%.

That doesn't really make sense. Your S7 = 2x fans and S5s = 3x fans, identical fans.
