If I was to give a suggestion to bitmain engineers it would be to force a higher initial fan speed on reboot, like SP20 was doing.
The way it is currently setup, upon reboot there is an abrupt change from high speed fan to initially low speed, which I think is causing temporary chip overheating. Board sensors are not highly relevant here because sensors are probably removed from chips. I think that this putative chip overheating might be causing the initial higher error rate upon reboot. Once fan reaches high speeds, the system equilibrates and errors decrease.

Yes, whatever the reason it is something that Bitmain ought to deal with.  It may be thermal related as you suggest, but it may also involve details of how a chip disables cores that are creating too many hardware errors.  The restart problem doesn't seem to me to be thermally related, because I've seen roughly the same situation with room temperatures more that 30 degrees C different.   (If the problem is an algorithm hardwired into their chips, I doubt we'll see any improvements.)

yeah, most likely the actual chip function as it is unlikely to be temperature driven if 30C ambient difference shows the same effect. maybe abrupt shutdown also messes up with chips as well.
i had killawatt that died and S7 was connected through it. Once I restarted the miner , it was showing lots of errors for the first couple of minutes, which mostly disappeared upon soft reboot, but it too good 1-2 hr until error rate came back to usual 0.0064% and stayed there.

Bitmain is all sold out of all S7s Batch 1, 2, and 3. 

SPECULATION (without any facts)

Is there an introduction of a new product? Maybe with the new chip.

Are they releasing the new S7+

Are they now trying to catch up?

Are they freezing sales to avoid loss with the increased BTC value?

Just Saying

Getting caught up, IMHO.

IF an S7+ were to come out, that would not stop them from making the S7, IMHO.

I do not see a new chip (14nm or 16nm) coming out until possibly this time next year, IMHO.

I personally do not feel they are freezing sales.  If the price of bitcoin continues to rise, they could simply continue sales while increasing the price of the S7's in proportion to the rise in bitcoin price and difficulty to continue making profits.

just a weekend there, we will probably see new batches on Monday or even sunday pm.
If bw will really produce something in winter time, BMT will be pressed to accelerate the 14/16nm rollout.

It's possible we could see Batch 4 and possibly Batch 5 with it as well on Monday.  However, new batches may not be available until Friday of next week.  I think they would rather be more prepared to ship orders out within the time frame they specify to improve customer satisfaction and to relieve pressure of meeting deadlines.  However, I'm not there and I cannot see what they have or have not done.

If bw will really produce something in winter time, BMT will be pressed to accelerate the 14/16nm rollout.

I don't believe they would feel hard pressed.  I think the mark up with the price of the S7 may be quite considerable in relation to actual costs.  Which means, they would still have room for price adjustment if they desire.  It all depends on the price of BW's gear IF they actually sell it.  Miners will be calculating ROI on rigs made available by multiple suppliers and will purchase which ever rig they deem as more viable for their situation.

Again, this was only speculation on my part.

[philipma1957]

The batch 4 will not start for a while. My guess is Next Friday.

As for me I ordered batch 2 on the 29th paid for it on the 6th due to the underhashing issues on my batch 1 which took me 2 days to trouble shoot and post a fix.

So no shipping info on my purchase.  Just waiting  for info I hope to hear from them.

[torepia]

I see they uploaded S7 firmware today, nice!

There is also a 550Mhz one, anyone got S7's running 550 default clock?

Does anyone know what firmware changes/fixes yet?  I don't see any readme with it.

Thank you your insight sir.
Received several s7 b1, configured in my kitchen and took over to datacenter.
All running 4.8 excellent. Only problem I had was one corsair psu did not start so I was hashing with just one board on one. Replaced psu and fixed. Bitmain psu's working great.(just have a few)
Was easier to install in the rack when I attached the cables to the s7 first and then to the corsair.

[carlosmnk]

 

This afternoon (Spanish hour), i've seen Bitmain reopened the batch 3 sales, so i'd put 1 S7 batch 3 in the shopping cart, and now, it still is aviable!!

Either way Bitmain I thin has the lead.  They perfected the 28NM instead of jumping into lower NM.  I suspect they are also r/ding the lower NM at same time.

They don't have to do one or the other they have a lot of capital.  I think it's likely they will be able to release a lower NM once needed.  But right now no computation so they will remain 28 NM.

S7+ would not surprise me if they have a while till a different manufacture releases.  I think S7+ is much more likely then S8.

Your welcome.

I just believe if and/or when 14/16nm chips are available in rigs, they will be quite pricey.  They should be able to get 0.06 to 0.12 watts per GH/s more than likely.  Which means they would last quite a long time in regards to being able to reach ROI.  14/16nm chips aren't as cheap compared to 28nm chips either.  It may also be a more expensive assembly process of the blades.  Investments may need to be made for new equipment within the assembly process which drives up costs.  I'm saying all of this to emphasize the price of 14/16nm rigs will probably be quite expensive compared to the S7.  They could make rigs with less hash rate that are more affordable though.  Only time will tell.  

The S7's 0.25 watts per GH/s is still quite good to last a while before the difficulty gets out of hand.  I say this because it is my belief the price of bitcoin while rise to a higher percentage than the difficulty between now and the end of June, 2016.  I still believe we may have a similar episode with bitcoin like we had with litecoin this past July [The ole pump and dump].  However, when LTC dumped, it's price after dumping was considerably close to double what the price was in the month of May before the pump began.  Also, I've been seeing a lot of great news lately that tells me we will have a lot of BIG money coming into the fray soon.  [Through Gemini Exchange and Winkelvoss twins ETF that may come on line soon.]

I honestly believe from now until the block halving will be a great year for bitcoin mining.

They are taking preorders and have a price for bulk buyers

“The miners are now available for pre-order at a price of 0.87 BTC with a minimum order of 333 miners which is 1 petahash,” Virgilio Lizardo Jr., Head of International at Bitbank told Bitcoin Magazine in an exclusive interview. “This price will be available until November 11, 2015. This winter, the miners will be available with no minimum order required; the price at this time has not been decided yet.”

Hey all,
Pardon the brief topic change but this S7 thread seemed like a good place to get some assistance. I'm new to the network side of things, and had a question for you guys about accessing an S7 remotely.

There are 3 S7's directly hooked up to the cable modem itself at the warehouse. I purchased a static IP address and can access the main cable modem config page remotely which lists the miners with IP's such as :192.168.0.5 - .0.9. When I type in those IP addresses from home, I can't access any miners (which makes sense as I understand it.) Can anyone offer some guidance as to what configuring i need to do on the miner to enable remote access. Thanks in advance for any help.

Put a cheap laptop remotely and use teamviewer.
Cable modem has a dhcp server to it is giving your miners ip addresses.
You can connect the laptop and remote control it with teamviewer and fire up browsers to monitor and configure the miners.
TeamViewer is free if you don't have many connections open at the same time. So you would have just one connection to the laptop and it would do all the operations

[mountainminer333]

Wolfen,
Thanks for the idea. I never thought of that and I'll definitely keep that in my back pocket of options However, I'd like to be able to do it properly just so I know how.

I don't know what you mean exactly.
The laptop scenario would be the safest.
Have been doing it for 2 years.  It is seamless.

wellllll I'll just mortgage my house and pre-order ..... ... ... not!

The only way I'd be able to afford 333 units would be if some long lost uncle died and left me a hunk of change... That is not likely because everyone in my family, except for my dad, has kroaked already. No rich uncle here.

I paid off my house 8 years ago... I hated the mortgage payments... eerm ... I hate making payments for anything. If I don't have the funds available, I don't ~need~ it. Financial responsibility.... now only if that mentality was common in Washington DC.....

The other lingering question.... what kind of infrastructure would I need to support the running of 1PH/s  ... electrical capacity, cooling capacity, physical space etc.
