[Overclock the Antminer S1 to 200GH/s] The EASY way! - updated to 393.75MHz ASIC

[nexus99]

WHen I overclock to 200 I get TONS of hardware errors. But at 375 I get about 195 GH/S and no errors. Interesting.

I have another unit running at stock that gets thousands of hardware errors and runs about 2 degrees hotter than the others. Any ideas? Its green LED is also very weak compared to the bright green LED on my other units.

Same here, except for the LED. My other 4 are awesome, just the one problem child.

Definitly some units handle the overclock better than others. Diference in the green LED? Prolly just component variance.
I own 6 and they dont all display the exact same green tone. Some brighter, some darker.

Other threads claim that if the error rate is below 2%, your fine. Have you done your math?

Cheers

quick calc (not the official formula but good enough)  HW/DiffA= less than .02   you're good.

I can make that file and script for 393.5MHz, but I just need to look at the value.  I'm not comfortable recommending it, as I haven't tested it myself, but maybe if it's good, I'll switch to it, also.  Thing is 400MHz is getting me over 200GH/s  (202GH/s+ on 1 Ant and  204GH/s+ on the other Ant)

I'm making a script for another forum member for  --load-balance so I'm uploading 2 files to dropbox so I'll just make it 3 files 

Brb...

Hello
Palawan, could you write the file for the frequency 393.75?

At the Goxxed thread, ppl r saying that this is the sweet spot between speed and error rate.
As per trying to edit files for myself, sorry but I lack the necessary IT skills.

Any help is appreciated 

Thnks

Ok, NorTiaN; here's the instructions to switch to 393.75MHz  ASIC's speed.  I'm assuming you're on  400MHz right now, but even if you're not, this should still work.  Values are courtesy of jedimstr   https://bitcointalk.org/index.php?topic=348327.msg5494459#msg5494459

ssh to the Antminer as root and copy and paste everything in the box below:

Code:

clear
cd /etc/config
mv asic-freq asic-freq.400MHz
wget -O asic-freq http://goo.gl/ASmTAE
chmod 664 asic-freq
head -n 25 asic-freq

Reboot the Antminer S1

Good luck.

In order to overclock your Bitmain AntMiner S1 ASIC to provide 200 GH/s and low HW Errors rate with our settings you need to follow the steps below:

Code:

- Login with SSH to your AntMiner S1 ASIC using the IP and username/password you’ve set it to use.
- Type “cd /etc/config” (without the quotes) in order to get to the folder where the config file is located on the miner.
- Type “vi asic-freq” (without the quotes) to edit the config file, comment the currently set options by placing # in front of them and add the following lines or directly replace the values with the following ones:

option ‘freq_value’ ’5f05′
option ‘chip_freq’ ’393.75′
option ‘timeout’ ’36′

- Save the changes you have made and type “reboot” (without the quotes) to restart the miner, so that it can apply the new settings and start mining at 200 GH/s with the overclock settings you’ve set.

The Antminer Asics will be running at 393.75 Mhz

Make sure you check your temperatures after 30 minutes and ensure they are under 50 degrees c

I am running 8 x ant miners on individual Corsair CX500M power supplies at this rate for over 2 days now

Good luck.

My post above is for people who are not very experienced with vi editor.  It's copy-and-paste method by downloading a modified asic-freq with the correct values.

Thanks.

Any chance to get it higher than 200? Mine is at +/- 205 and my HW errors are quite low.

You can use WINSCP to edit the files too if you don't want to use VI. VI is terrible.

had the same thing happen on my second S1 Antminer.  First one using a 750w power supply.  This one using a 600w power supply.

I am new to this, I was able to follow your instructions to login and view the file but how do you actually change the lines, what commands do you use to edit and save the file.

thank you

Sorry my first post wasn't very user friendly it assumed people were already familiar with vi

Please follow palawan's powst above as he has a simpler method to get this working OR connect to your machine using WinSCP  and edit the file that way

Hit I to edit.
When edited, hit ESC and type "wq!" (without quotes)

[solarion]

...better still! Go to software, update available pkgs, and install nano editor. Vi is the pits.

[tripppn]

I used your code in the op to oc to 400 and I seem to be running at the same speed as 350.  What to I need to copy/paste into SSH to put it at 375MHz

NM Went with the 393MHz and it worked like a charm.. Thanks for your info.

[Chivas12]

Is it possible to overclock more then 400 MHz?
I want to test 600 and 800 MHz but i dont know to
set it up.. Can anybody helps?
I post the results after testing.

The short answer is no.  There's a few posts on the bottom of page 3 that explain why.  Plus, not all S1's are equal from factory.  Look 3 posts above yours and you'll see some can't handle even 400MHz.  Depends on the quality of the boards and chips from factory...

Ty for your fast answer.
