Thanks for this link Philipma1957 - I just read the whole thread and will be tweaking my L3+s and L3++'s tonight!
Could I ask you a question? I have been looking for a watt meter for testing wattage use on my miners but am having real difficulty finding one that will work with 240V. Could I ask which one you use (brand/model) or if you could recommend one?
Thanks!
A standard Kill-A-Watt meter will read up to 240v, just dont run more than 1800w/8amps through it.

No, I mean the power consumption savings were something like 10-20 Watts only. If I remember right.
most s-9 did .11 at the wall
so a 14th used 1540 watts at the wall
very few of the 30+ s-9's i have had did 0.098 at the wall.
here is a link to L3+ software issued by jestanop
https://bitcointalksearch.org/topic/bitmain-l3-voltage-control-toolfree-3546316
@ mods this is very important to not delete it shows that voltage can be adjusted and power savings of 5 to 20% can be done.
So most likely the s9i is using software like this.
It also means if you have s9's you may be able to reduce the power they use.
I also suspect bitmain will not release the s-11 until Nov or Dec.
as this gear buries prices on both canaan and Halong.

Sorry if I missed it but I don't see any discussion...
Bitmain new slide verification when placing an order does not work for me. Tried 2 different browsers.
Net Err. Please refresh, or feedback (00)
Anyone has done it successfully or has a work around?
Edit:
It worked after I cleared cache and cookies.

Can get the same hashrate with low power for L3+ ?
Did you try it ?
It seems the firmware for S9i is available for S9. Nobody have found it ?
you are probably right @philipma1957 it's just voltage.

APW3++
In my experience the APW3 pulls up to 100w more at the plug then similar higher quality PSUs
Would high quality PSUs be something like this??
It is a dell psu.

I see the same from the 13.5TH/s s9 using HP HSTNS-PR16 2450 Watt PSU and room temp is 64F
Measured voltage 242v
My S9's at 13.5 TH/s consume on average 1417W with an APW3++ PSU on 230V. The room temp has been 35F-40F during the period I watched consumption.

13.5 THs at wall is about 1550 W measured.
You must be using are really inefficient power supply if those numbers are what you are really seeing.
I run thousands of these things. A 13.5 TH s9 with a good PSU draws 1360-1390 watts at the plug.
APW3++
What is your room temp?
What is your voltage?
A hot room and lower voltage like 220 vs 240.
Will affect that psu.

A couple of thoughts about the very moderate efficiency improvement. First, I wouldn't be surprised if they are just reducing the hashing board voltage by 1-2 volts. You can do this on the D3 with the Blissz firmware and it lowers the electrical usage without seeming to lower the hash rate. (sometimes undervolting even improves it a bit.) I also notice that they are quoting AC electrical usage as +10% now. If my memory isn't completely out of whack, I recall they used to quote it as +/- 5%. Anyone else remember this?
Its been 10% as long as I can remember altho the first page of this thread says +7% on the power usage quote.

The S9i is only slightly better in terms of the power efficiency than the S9.
Yes 1300W instead of 1400W for the 14TH. Disappointed.
I expected a 20 TH/S for 1000W
that's good idea

Does anyone knows the average usage of the S9 machines depending on their hashrate?
I would like to add some of my machines to a mining farm and actually I don't really think the 14th machine takes the same power as the 13th machine?
13,5th is average about 1400W ( not sure about that, but that's what I am paying ).
Thank you!

13.5 THs at wall is about 1550 W measured.
Not sure it is, measured it with 1380 W recently.. I even have one miner with only 2 hashboards running, so they should decrease their power usage of 30% ?

Has anyone here heard of rumors about the near launch of an Antminer S9i?
I know someone who claims that Bitmain is going to launch a mining rig (Antminer S9i) that mines Bitcoin at 35% decreased use of electricity.
The launch is supposed to be on 1st April. Does anyone have more information on this?

So they did release this miner.

I'll quote you on that when I get the gear. I'll compare them to the A841s and the S9s that I have. I needed to expand the mine anyways
