Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 245. (Read 528055 times)

My "living" does not depend on bitcoin mining.  Am I wanting to use it to get ahead if possible?  Yes.

My wife is an accountant for an oil and gas company with a 6 figure salary and I have my own business training telephone technicians.  I have more training lined up the first quarter of 2016 with CenturyLink.  I probably could have more business if I were to get out looking for it.  I've been educating myself on other topics lately instead of making calls to gain more business.  I used to be on the road training telephone technicians 45 to 49 weeks every year.  However, I'm quite content lately just being home with my 4 year old son instead of on the road away from my family all the time the way I used to be.  Is there a problem with me trying to workout a way to spend more time with my family?

You got your little "tongue in ass" poke in as well.  So be it.  I don't understand why you ,and others like you, get their freak on with hate speech towards others conducting business with someone else that has nothing to do with you?  I could think of a number of reasons why.  However, I'm not going to waste any more of my valuable time with the likes of you.  You might want to check yourself next time before making your pokes of hate.  Invest your time doing something positive instead of something negative.  You might begin to have a more positive outlook on life and yourself as well.

Crap, yes but I just forgot on these two. I usually let them run a bit on the stock firmware.
Thanks for the reminder. I'll do it remotely
Just got a 90TH/s spike on nicehash with 17 s7's
Both new miners running on oct 23 firmware now.
A ok.

60% =   95%- 100% ie 4000 rpm

try 55% or 50% 

the policy used by our customers is really painful,
the warranty period of 90 days is too painful.
if hardware is fully functional it does not need all those frequencies and then not use them because they will void your warranty.
the miners who produce are scaresa quality for this date only 90 days warranty.
Sieto only attached to money.
another thing, if a user pays you in BTC have the right to do it to save as much as possible, both in the shipment, especially the customs fees.
what game you're playing?
it seems that people are stupid?

Surely there is a practical side to the Warranty issue? If there is a visible trace to something being done that will void your Warranty. Broken Warranty Seal, then you have voided your Warranty.  

If you have done something that is not visible. Run multiple S7 on a single controller or upped the Frequency and then set it back, you may have voided it but how would Bitmain know?  

That is unless actions are logged like on my GT-R and can then be later examined by Bitmain?


Rich

Do you immediately install the latest firmware as part of staging?

Got my two s7's  just now. B3
All configured and running 4.8
Just wanted to note, the middle hash board gas a little bit of looseness in the chassis slot, both of these.
Two outside boards snug.
I believe that was the case with my others.
If you hold the middle board snug and flip over a few times you should be able to detect loose heatsinks.
Off to the datacenter.

Well well wellllll ....

It seems that I have a FedEx tracking number for my S7's


Whoot!

 

typical corporate stuff...do things that are impossible to reconcile (do it/don't do it, discuss, void/not void)..sigh

in video form-I got a few laughs ( although it is a bit long):

Does the warranty remains If you use one controller multi-S7 unit with long data cables from S5+?

So you're looking for people to post information about how they have voided their warranties, so other people can void their warranties, forcing them to buy more Bitmain product if something goes wrong.

Got it.

That is why I asked more questions.  It seemed like a lot the ideas that void warranty. I find it very weird to throw out idea's that some would take voiding warranty.  Tell people tell us how it goes with voiding warranty.... but this is not permission.   Makes 0 sense.

Just like vertical which seems simple.  This was done in most cases with fan screws holding the legs... but we are not suppose to unscrew fan.  Change frequency... but if you over or underclock it voids warranty.  I do not follow the post I hope they remove it personally.

at the moment, many are interested in what some brave members have done to S7.  Also, experience so far without modifications.

Got it. So you're looking to hear back from people that have voided their warranties already...

I'm so glad I quit you, Bitmain.

Here is some information that I have gathered:

Fan Speed             My Findings
                          S5          S7
65% = 4200   
40% = 3600         3000      3120
35% = 3200         2760      2760
30% = 2800                     2520
25% = 2500
20% = 2000

yes, maybe it is different in batch 3, but my B1 S7 also does not change speed anywhere between 100 and 65%, 60% also not much change, but it starts to relatively rapidly decrease speed starting at 55%. It is not like 65% means 65% of speed. The meaning of these % is not very clear, but it is similar to the fan % on SP20 where 10% does not mean 10% of fan speed.

Can you go deeper on what is allowed on frequency change without loosing warranty?  Just want a full explanation here.

A lot of vertical designs on S5 used the fan screws to secure the legs used to hold the miner vertically, are you giving permission to unscrew fan to attach  legs to do vertical mining?

well, people talk about what is current for them even if it looks like distraction.
BTW, strict warranty conditions are probably censoring posted opinions.

I have a few points:

1. I upgraded the software, but in the end it never went to a page described in the manual. Instead, it went to the system overview page. i thought that it is done, hit reboot, THEN miner disconnected from the gui completely and I feared the worse, but it recovered and reconnected on its own.
Bottom line: update was successful, but did not go as described in the manual
2. after software update it looks like speed is more stable, but approximately 30Gh less on average (after only 2.5 hours) with everything else being equal.

finally, B2 order placed on 10/16 is on the way, but 10/22 order is not yet.

I like the built quality, performance and lightness of the later S7s; however, my early B1 was a different story (order date Aug 30). Housing was different, and two of the boards had loose chips that I didn't know. Out of the box only 1 board worked. info@bitmain was quick to respond with my warranty claim, it usually took 24 hours for them to respond. After 3 days of communication I was expecting an email last night about replacement but no email received, so I guess I won't be hashing with three boards any time soon 

s7 batch 3 not respond to setting of speeds fan.  brand new...
set to 60% and then confirm when S7 boots up, and the fan runs at 4000 and 3800 rpm. I also tried a restart switched off.
temp is 54 and 52, hash is 4,900 +/-
