which s9i firmware is best?

[philipma1957]

pretty simple question.

The original firmware did 14000 gh at 1475 watts

I put in the Nov 7 firmware it does

14006 gh at 1257 watts   a watt savings of 218 watts since I will be setting up a lot of them  it is a nice savings.

Antminer-S9i-all-201811071119-autofreq-user-Update2UBI-NF.tar.gz ..... I am using this one

Antminer-S9i-xilinx-201811301418-autofreq-user-Update2UBI-NF.tar.gz ........ so how does this one do?

Note to load the nov 7 version I had to load this below

Antminer S9i - Package to Fix Upgrade Failure
FileName   Description
fix_mac.tar.gz

all info came from below.

https://service.bitmain.com/support/download?product=Antminer%20S9i

on a different note
has anyone flashed s9j to s9i and improved efficiency ?

and lastly

I have a really nice s9i 1260 watts  fans at 3200 and temps at 77
I have an okay s9i        1295 watts fans at 3650 and temps at 77

seems that I got lucky on one of them

Phil,

I just installed a few switching PDUs at my data center and here are numbers from the wall that I have on some of my S9i-14.0 miners.  All are running 20181107 firmware.  I may install some other firmware on the miners when I have time to monitor them.  Temps are around 62-67.  Firmware has been rock solid and I did not have to install the upgrade failure firmware first.  I believe I have a total of 55 S9i-14.0 miners running this firmware so this is just a sampling from 1 cabinet.

Average     Real Time     Real Time Power   W/tH
14.010          13.955          1207 W          86.5
14.126          14.124          1210 W          85.7
14.226          14.279          1195 W          83.7
13.988          13.985          1190 W          85.1
13.996          13.927          1162 W          83.4

My s9 13.5th/s auto freq is running the Nov 2 update at 1130-1230w pending fan speed. I set to a static fan % though cause it likes to wind up and down considerably and annoyingly.

I'll update about he 14th unit I have in a couple days.

13.996          13.927          1162 W          83.4

These are the best numbers I have ever seen if indeed these are the numbers at the wall. I have metered 240v, but only in amps. I can therefore only calculate approximate wattage but not near exact. I just got a bunch of 13.5 and 14TH S9s in. I was really thinking that the 3rd party software with the new ASIC boost enabled was going to be my best option, but this 20181107 firmware result is the best I have ever seen posted I think by at least 5%.

I was able to get a 14th s9i down to 1150-1160w as well. S9 is pretty viable still with cheap power, just wish I had some. My fiat reserve is about up and I'll have to shutdown unless a market rise to supplement, which I don't expect soon. I'm about $0.115 power and very happy I've lasted this long as very small miner though 2018 to now. I'd say I'm proud but wish I'm able to endure while I have cool of winter here.

[philipma1957]

If you get cheap s9i and use braiins os. You can go to 815 watts and 10040gh.

About 80 watts a th.

You must use asic pools.

But 80 watts is really good.

You would need more psus and more room to squeeze out that extra three watts.

Can you follow up further?

Antminer-S9i-xilinx-201811301418-autofreq-user-Update2UBI-NF.tar.gz ........ so how does this one do?

If I'm reading bitmains details the 20181130 firmware correctly, hash rate and power efficiency are both lowered.

I'm getting the same numbers as you posted from the 20181107 firmware +/- depending on fan speed/ambient temps.  I'm looking at
which direction to go when season changes next:  flash bitmains firmware when needed or try braiins.

If braiins is better all around, Have you done one of your video's on braiins?

You should wait a little bit, by the end of the month the next Braiins OS version will come out, and i think they are implementing an "easier method to go back to Bitmain's firmware" which probably involves the Braiins OS web ui, because if you do install Braiins OS right now using their python script (not the Web UI) it is VERY EASY to go back to the original firmware as that script makes a backup first, while the current web ui method doesn't.

Though he hasn't posted any videos, he has posted lots of results, GOOD results. I never expected those S9 to become this efficient AND stable. I see little reason to mess with any other firmware at this point... (And i happen to know results from another person that used it in hundreds of units...).

Any news? I was wondering what is the best firmware for my s9j miner.. I want a firmware that I can set frequency per chip and even underclock in some senarios. can you help me with that?

BraiinsOS allows you full control over your asics frequencies and voltages, fans can be set at fixed speeds or ignored and sensors can be disabled/ignored. This allows the greatest flexibility, and with care you can find the best efficiency per hash board, but you can also harm the miner if you go reckless with the voltage and speed settings.

No, these settings cannot be changed per chip, only per board. This is probably a hardware limitation.

As always, at a given fixed speed lower the voltage until you see the actual/current hash rates differ too much then go back up a notch on that voltage. If you change the speed, do this again, remember this has to be done per board, as every board is different.
