If you referring me as a "that guy" then i can tell you the answer .. The sample time for each hashrate reading was around 30 minutes each . Im used a Kill A Watt device to measure the actual watts ... That device its not the best option for this but can give us some info Also the hashrate reading is from the antiner S7 " Miner Status" page , the reading on the pool side is always a little bit better in my case ...
I have another miner running on 731 for more than 10 days with 0.0093 average HW error and 4.900TH/s average hashrate reading from the Miner Status page , but the average daily hashrate reading on the pool side is 4.939TH/s

I wonder what how long the sample time was on that guy's hashrate readings. The theoretical max average hashrate for 718MHz on 135-chip S7 is a shade under 4.85GH.

I noticed it the day it came out. I updated all of my miners with no problem. I can't tell a difference so I'm not sure what changed.

I had little problems with miner status page being blank and no hashing after changing settings for 2x Antminer S7, batch 9.
Cgminer settings were ok.
So I tried this very firmware, and no problemo.
Hashing again as usual and now changing pool settings etc. don't cause any troubles  

On the main bitmain thread their own man, @Bitmain Warranty, says that you should NOT update your FW IF your miner is working fine.
Take the "hint" from the source and avoid a chance of trouble (bricking the controller), as phil said as well.

that aside, i had to upgrade two machines that were on Oct 23 version to Dec 11 FW version because they stopped hashing due to a known bug (connect to IP 14.14....). Sep 15 FW machines are still OK.

I'm wondering why don't Bitmain announce this FW and post here a changelog...

".... but I don't believe the running 4.8 to 4.9 with 15 watts."

There is my stat with diff fq , ambient temp , core temp with the same miner ...

Miner : Antminer s7(132Chips) with firmware: "S7-20160305-700M-2fan.tar" i did not updated to the latest one yet

No don't touch it.  I once was young with bitmain and thought the same... but once I bricked a S3.  It changed my entire thoughts of firmware.  If your bitmain gear is working and there is not a hug issue (like one S3 reset button did not work... ok that is big).   But most do nothing for you.  And you risk you gear when it's already working.

Best case you get almost nothing changed.  Worst case you have a IO board with  bad flash you either have to get it fixed via serial to usb (going to be a pain) or buy a new iobaord flashed from bitmain, and have downtime.

Don't update .... just dont this is for others. Since you did it already.... but I don't believe the running 4.8 to 4.9 with 15 watts.  You will have to provide a lot as others mentioned.  You would have the best batch 9 if running default freq on the forum.   I don't see getting that with default freq from working with others.

On:
F)  Bitmaintech has issued a lot of   bad firmware updates                                   
So how do you know the original firmware was not one of those ??

You know as your miner is working decently to spec.  You get a bad firmware update it BRICKS your unit.  Not going back to old firmware... you own a brick.  Until you do a lot more to fix.

Just like u was a newbe once ...                                                                           Strike back 1

B) No before evidence in screenshot or photos                                                   strike 2
You right, im not seating front of my pc and making screen shoots all day long        Strike back 2

C) No after evidence in screenshot or photos                                                      strike 3
I just shoot one screen shot for you a few minutes ago                                           Strike back 3

D) No mention in your first post that you did it to a new model 135 chip              strike 4
my mistake , its from batch 9 , but FW update for all S7 with 700 def fq/2fan           Strike back 4
just read the firmware name  

E) S-7's have had hijack issues  so this could be a new way to hijack your s-7      strike 5
monitoring 24/7 , none of my S7 have this isse ... Im a it tech person                   Strike back 5

F)  Bitmaintech has issued a lot of   bad firmware updates                                   strike 6
So how do you know the original firmware was not one of those ??                          Strike back 6

G)  You first post did not mention you knew this would improve your gear             strike 7
No,I never know,that is why i upgraded still have older firmware's to downgrade  Strike back 7

no documentation = not true

you could simply be a bitmaintech agent  getting   people to load a bad firmware.



I hold zip against you.  And would prefer to think you tell the truth.

Now all kidding aside  7 bad points above.

If it does what you say it is worth it

  to upgrade  the  s-7 as a 4.9th      with  0.0002 errors is much better then a  4.8th with 0.0400 errors

So to those that know what they are doing     weigh the downside against the so called gain and test for us.

We  would love to see  some long term trusted people showing this firmware works on batch 9-16  and improves numbers.      

Upside : Antminer S7 (4.73Th/s) running stabil on 718 with 0.002 error rate , hashing 4.9TH/s avrg temp is under 62 , Fan on 60% , before the firmware upgrade ( S7-20160305-700M-2fan.tar ) the same miner was not running great on 718 .. it was hashing 4.8TH/s avrg but with 0.04 sometimes 0.1 error rate ,lot of re ejected shares , temp was under 62 , fan is set to 60% ...

Downside : with 718 stabil , low error rate , 4.9TH/s avrg , is pulling 15 watts more from the wall

keep updating that firmware until you brick your gear. 


Just saying what is the upside to the update?  None that anyone can show.

What is the downside you brick the controller.

Ooo, when u upgraded your firmware was there any changes or improvements? as much as i want to upgrade, im still worried hahaha

Will keep an eye for changelogs for the new firmware.

I updated firmware's (S7-20160305-700M-2fan.tar) on 4 of my s7's in the past month without any problem , all of them working great  , now im just wondering why we got another firmware upgrade 6 weeks later

Would suggest not to update as there are some that has bad experienced that their miner becomes a brick.

As they say Don't try to fix something thats not broken babe <3 

Just checked bitmain website for firmware's and found out there is a new one for S7 with 2 fan dated to 20th April 2016 ("S7-20160420-700M-2fan-4320.tar") ... did not find any change log ...
Should i (or anyone else) upgrade the miners to the new firmware ? There is any change log available somewhere ?
