I did the update, and although I do like the additional info in the Miner Status screen, I'm not sure that I am getting an improvement.

At stock frequency (225 on the s3+) I still get standard 440 ish hash rate. At 250, I get 480 - 490. I am on F2Pool, and these numbers are from the GH/s paid column of stats.

Running at 250, I get a temp of 40 (max). Perhaps I should go for a higher frequency and take it up to about 50 degrees. Thoughts?

I start getting problems at 47-49 deg. You could easily take it up to 44 though. I would (disclaimer: if you bust your miner I didn't tell you to do it!)

What freq to you run at to get into the mid 40's? And can you tell me then what kind of hash rate you get?

(of course the point here being S3 versions, but again I don't know how many S3/S3+ versions/hardware/firmware support it)

There are all sorts of anecdotes on the Forum that lead you to believe that some versions of either the S3 or S3+ have firmware voltage control.

The thing is that I cannot find a single mention of someone who has adjusted the voltage from cgminer and then measured the Core Voltage to confirm this. Also all the pictures that I can find of S3 & S3+ hash boards seem to have the TPS53355 Buck converter that relies on a resistor potential divider to set the voltage. This is what people do the pencil Mod on, or physically change the resistors to change the Core Voltage.

I have an S3 & an S3+ and neither of them support voltage control. There may well be a version that can be software / firmware adjusted, but my theory is that the code is there to support the S4 which definitely can be controlled.

The voltage control works for miners that accept voltage control.
It's passed through the same interface as the Bitmain version of the voltage control code - and note that the Bitmain version of the voltage control code is the same for all S1,S2,S3,S3+,S4,S5
(of course the point here being S3 versions, but again I don't know how many S3/S3+ versions/hardware/firmware support it)
My point here being that I've no idea which Sn work with voltage control, but if it is possible, then the option on the web page will do it.
If it's not possible, then the voltage on the web page will have no effect.

Edit: the default voltage looks like 0725

Performance increase is ... well ... master cgminer is more of a lack of performance decrease

My S3 that has the latest changes in it seems to get about 1/4 of the rejects of both my S2 and S5, but both S3 seems to be pretty consistent to get around 440GHs Paid - they are not S3+
(I only run S1s when testing code - they cost a lot more to run than the BTC they make)
S5 is still Bitmain version, S2 is well, I still wonder why my S2 still works

It doesn't have the WorkDelay option in it either.

I'm working on doing an updated version of all S1/S2/S3 and adding in S5.
It's a balance between running my pool that really doesn't have much of a hash rate 2 to 3 PH and doing cgminer updates ...
The pool wins out always for priority even though it doesn't pay very well Tongue

Kano,

Trying your update out on an S3+ and running a side by side comparison to another S3+ both clocked to 250. Ill provide stats once we have a full 24 hours of data.

Question, I noticed a few posts this page to 1-2 back that mentioned undervolting via your GUI doesnt do anything.

Can you clarify the utility of this feature a bit? Also, would setting the voltage give better returns?

Lastly, can you provide the syntax format to use for voltage? I didnt see it in your readme.

For say 72 do you enter 0072?

Many thanks!

Sorry but Im hoping to not have to dig through 438 pages of posts on this thread.

Does anyone know off hand what the most efficient config is for the S3+ units?

Frequency Settings, etc? In terms of Gh per Watt. Underclocked/Overclocked. Just curious.

Thanks!

Also, I havent yet tried this update by Kano, but just wanted to say by the looks of it/others feedback - Really good work Kano!

I updated one of my S3, quick and easy, just follow the read me

First thing I notice is Extra nonces command for Nicehash is not supported.

Code:

sha256.usa.nicehash.com:3334#xnsub

It is a minus for me
For the plus side

I tested mining on Antpool. Got a nice improvement.
I got 550GH-580GH average after 20-30min of mining.
Gain of 50GH or 10-15% at 250Mhz

Nice job. Any plan to support extra-nonce command ?

Edit : Waiting pool stats to confirm numbers

You can incorporate the Extra Nonce feature into your mining operation by simply running your own Stratum Proxy Server on a local machine (can be a laptop or any PC).

Then point your miners to your local machine and you can have the ability to then point your hashpower anywhere you want with just one config file.

When I was running a lot of S5s and S3+ units, my setup in the AntMiner GUI was as follows:

Pool 1: Betarigs (which can be turned on or off from Betarigs)
Pool 2: My Local Stratum Server (Dell Laptop) - Which had a main pool and 2 failover pools setup.
Pool 3: External Pool Direct (-ck or Slush) in the event my farm was not rented... And my laptop failed/lost power connection etc.

Lastly, Extra Nonce was of course added in.

There are a number of guides on how to set this up. If you need the files and config/batch file I wrote I can post it this week.

Cheers!

kano said hes not supporting that you can put it in i think he said but hes not? Sad

but don't take my word on it i will try to find were he said it in the CGMINER thread.

Will do. I just updated one S3 and left the other 'stock' with both mining on the Kano pool. I'll let them run for a few days and check to see if there is any difference.

Check out the load on each one, you can see that difference immediately.

The miner status page update alone is worth the software upgrade.

It's been asked before, and the answer is no. If Kano doesn't chime in with the details search the thread and it should pop up.

Does anyone have a chart with the voltage / frequency settings for underclocking and overclocking the S3? I'm interesting in getting a better J/Gh ratio with a stable underclock.

Quote from: kano on August 09, 2015, 05:46:42 PM

Those are all in the Miner Configuration - Advanced Settings tab in my updated version

https://github.com/kanoi/cgminer-binaries/tree/master/AntS3
Besides having those voltage settings in the gui, the update also makes your machine run more efficiently, update today!

How does the update make the machine run more efficiently?

https://github.com/kanoi/cgminer-binaries/blob/master/AntS3/README#L73

Their version hits the chip for results about 60,000 times a second, 60k is the approximate limit based on as fast as it possibly can load on the CPU ...

My version, about 1000 times a second. More than often enough, and a much reduced CPU load so that other important things get more available CPU, as mentioned in the README.

It's a tiny CPU, they clearly never had the slightest idea of what was using up all the CPU.

Edit: oh also there's another CPU reduction in all cgminer drivers -ck and I have done where we handle the stratum work more efficiently.

So by lowering the CPU load you get:

"few if any delays getting and processing work" from README

This translates into less stale shares? A slightly higher hashrate? Less power draw?

I didn't test it just watched it but yea from what i saw to all the above .to some not enough but most like it and it gave me a reason to keep my S3 going and go buy some used ones and am looking for some S3 ++ at a nice price til we know for sure what bitmain is up to .

try it , it actually works nice i updated three S3 and it gave them new life . he also said hes working on one for the S5, if it's as good a update as the S3, i see all most all of the S5 problems gone.I do mean that i will be running my S3 for many month more dispite what bitmain does either way .I not just saying that or kissing ass,I don't believe in ass kissing if it works then say so .
