An Attempt to create a more complete freq value chart for the ant miner chip.

[philipma1957]

This was updated today.

With a list of links.  Also when the s-3 chip /miner comes out I will list the info here.

Here is a chart of freq values for ant miner chips. It is not complete.

my goal is to create a master chart of values  from freq 175 to freq 450







good links to help with over and under clock of the s-1.  also for under volting the s-1

We all know the ant miner chip uses freq values for over and under clocking.  My goal is to create a 3 part list.

One will be for usb sticks U-1's and U-2's

Two will be for S-1's

Three will be for S-2's

Instead of having to think what do I need you just look at the chart.

please give me feedback on this and more tested s-1 settings.

please feel free to add to the list. the goal is to get a very complete list allowing for easy reference guide to program the freq of your ant miner chip.



I would like to get as many possible settings for usb sticks s-1s and s-2s


right now I will test any u-2 or s-1 setting as I have u-2's and s-1s

As I order an s-2 i will test it.

please submit your settings.

Great resource! Anyone successfully operating in the 425-500 range?

[freebit13]

You can add this to the list for the S1. It ran better on an older unit that would throw a lot of HW errors at higher frequencies.

freq_value 5e82
chip_freq 387
timeout 37

215.625 ---------------------------- 1.725 ------------------------ 6206
218.75 ------------------------------ 1.75 ------------------------ 5102

the above codes were from my hand calculations, GH speeds added. 215.625 gives me 1100Gh and less than 1.1% error rate

Cgminer calculates values on the fly for any frequency for the U1/2s with the --anu-freq command. You can either run a U1 with cgminer and various frequencies in debug mode to see what values it generates, or you can audit the code that I wrote that generates it.

 thank you for the input  I set a new ant miner s-1 to it  here is a screen shot.  so another one that will work .  to all I will do more updates soon and thanks for info

[philipma1957]

and 387 looks like a good choice for an s-1

I will slap a k-watt meter on it later

[philipma1957]

my k -a-watt meter was running 1.5 s-1's on an evga  it read 589  adding the full one clocked at 387 freq jumped power to 977   so this is pulling 388 watts at freq  if I get 201gh and 388 watts steady this setting is better then the 393 setting most of us use for s-1's

This is what I want the thread to fill in as many numbers as possible.  I found when I used to mine btc with gpus small shifts in settings could make  big watt gains.

It could be that 387 is better then 393 for most of our miners. at least most s-1's

We run ours at 393, which pull 410W (+/- ~4W depending on unit) on a 80Plus Gold PSU.

I run most at 393.  I wanted to get 20 or 30 more values to test.. 

I am curious about  various freq and the hex  .   an easy pop in a number  chart up and down the freq would help to test as many as poosible.

image removed...

Nice one, it is pretty stable and reduced the HW errors... it might be a good idea to list the HW error rate in the charts too as it really starts to make a difference above 387.

[philipma1957]

this shows 2 s-1's

one at 387 one at 393

the 393 has the better hw rate and hashes a bit more but

the 387 uses 20 watts less power

these s-1's have variance

and a really full chart will help us with clocking.

BTW that one ant miner has a really good hw rate 3 bad   and more then 2.5 mill good
 It will be fun  testing the s-1's  .

Please send me freq-- hex codes

[freebit13]

I notice that even though the 387 has a higher HW error rate, you can see that it has more accepted shares and the diffA is almost identical between the 2... with 20W less power, it might actually be the better setting 

Nice work!

I am waiting for a merged usb2 bridge for my 19 port miner.  this will allow me to do up to 1.8 amps or 9 watts to a u-2

I will then play with your program.   will be nice if I get it to do this.  I can run a lot of air on the u-2 miner it should not over heat.

Hi guys, what values should I use so I can safely power 2 ants with a 750W PSU? I have so many PSUs I don't want to buy more

Could I do something like 160 GH for 250W?

Sounds about right.  I have two Ants per CX750M and run mine at 300Mhz.  I also undervolt to about .90-.95V.  This results in about 220W of power draw per Ant.  They hash

at about 153Gh.  I would imagine 325Mhz would result in close to what you want, power wise.  I calculate 8x325=2600Mhs x 64 =166400Mhs, so 166Gh and about 250W.

I run mine at 300Mhz because it seems like the best tradeoff between power use and hashrate.  The temps went down quite a bit too Vs. stock speeds.
