Sorry to be a noob but to revert the changes would the following command work or is there more to it?

Code:
cd /etc/config
mv asic-freq asic-freq.400
mv asic-freq.BitmaintechFactoryVersion asic-freq

This is great BTW, works perfectly!
Now I've got my head around manually editing the config file I'd like to try different values and whenever I attempt to enter the asic-freq file, it appears empty so I'd like to go back to stock (for now)  Wink

Thanks!

Yes, that is the method to go back!  If I may make a suggestion, I would do this:

ssh to the miner
Code:
cd /etc/config
mv asic-freq asic-freq.400
mv asic-freq.350MHz asic-freq

Personally, I don't like to mess with the original files from the factory and I just like to work with copies.  The only reason I can think of that you're getting an empty file when you're trying to enter the asic-freq file is that you're not in the /etc/config folder.

ssh to the miner
Code:
cd /etc/config
ls -la asic-freq*
less asic-freq.BitmaintechFactoryVersion
less asic-freq.350MHz     <--  if you haven't renamed it.  if you have, use asic-freq
vi asic-freq   <---  only enter when ready for vi  :D

less command is just to display (not edit) the file.  You can move up and down using the arrow keys.  Q to exit.  vi can be difficult to move around so don't enter it unless you know the shortcuts or you can get stuck in it.  I like nano more as a text editor but it's not on the Ant miner, unless you install it.  There's shortcut keys/guides on the internet.

Good luck!

I'm sure your method works but its not like the directions @ https://bitcointalksearch.org/topic/m.3915400 are any more or less complicated really.

the easiest way to oc the antminer is just modifying asic-freq directly...rofl
If you are not familiar w/ vi as an editor then just go to the webgui and install nano
then use nano to edit asic-freq....

nano FTW!

Nice guide! I may try this out when I get home. I do have a question, though. Do you know if it is possible to go with a higher OC speed than the 400mhz (using proper cooling, of course) I was thinking about a liquid cooling setup of some kind.

Thanks!

Thanks for the compliment!  Personally; I wouldn't try going over the 400MHz/200GH/s speed.  There's comments in the goxed original overclocking thread mainly to do with the voltage regulator on the board (S1 blades).  I'm very happy with the performance of the Antminer S1, myself.  I have 2 of them now  Cheesy   I might add 1 more, if the price goes to 1 btc (currently 1.45 btc on the Bitmaintech website), but that's my limit as I'm about to pop the circuit on the 120V/15A outlet I have them plugged into.

I got Satoshi's avatar!
I must say I'm divided on the psu issue now that I've had a chance to test a little...

Bought my first miner with the red & black 12V connectors on the boards and ran it off an Antec Neo Eco 520C 80+ bronze which has a single 12V rail delivering 480W at 40A and got mad hardware errors at 400mhz so clocked it down thinking it was the power supply.
I then bought an Antec 750W High Current Pro 80+ Gold which has 4 12V rails delivering 744W at 40A per rail and the hardware errors were only slightly reduced but it was still not worth running at 400mhz.

So, I bought a second miner now with the yellow and black 12V connectors and connected it to the 520C and clocked it to 400mhz and it's rock solid with <1% errors:


In the end; same 520W PSU, 2 different generation miners and completely different results, one with >6% errors and one with 0.6% errors at 400mhz... go figure!

I also notice on the newer miner the fan runs faster as it seems to want to keep the boards around 40o whereas the older miner will keep them around 45o... I guess there must have been an update to the PWM management software?

I followed this and my antminer shut off immediately when I restarted cgminer.  It then would shut down whenever I powered it up.  I thought maybe the PSU wasn't powerful enough even though it's a 750w and I thought after OCing they pull 550?  So I tried unplugging blade 2 and blade one booted up and mined perfectly.  It was hashing at slightly over 100 Ghash.  I then just loaded in the factory settings and plugged blade 2 back in.  Working as it was.  So...for anyone who runs into the same issue that's how you fix it lol.

My question is, does anyone know why the 750w PSU wasn't enough?  Do you have any recommendations on what PSU to use to OC it to 400?

1. assume a 100-200W "overhead" for 3.3V and 5V on sub 1kW non Gamer PSUs
2. cheap supplies almost never deliver whats on the box
3. look for single rail and check the product specs for max 12v load on these
multi-rail psu often give high numbers per rail but they wont apply combined
4. if avaiable check the datasheet for "load on 12v" versus "combined load"
5. all pcie + molex are on the same rail in some ones - use the 6pin/8pin eps plug for the second blade

...

7. or just get a server power supply - they are 10x cheaper and more efficient anyway Grin

It had been running for 24 hours at a constant 40-41 degrees.  This is prior to overclocking.

When I ran just blade one it ran for about 2 minutes at 100 GHash and 400MHz so maybe it's blade 2 that's the issue?

This is the PSU I have...

Aha, that's a 4-rail-12V power supply, none of which has greater than 20A on it.  So, my guess is, yes, it's a power supply problem.  I'd take it back and exchange for a single-rail 12V power supply that has at least 45A on the single +12V rail.  That should do it!

I use corsair cx 650 And corsair cx 750m for my 2 Ants OCed 400mhz.  You need single rail 12v with 42A to be safe for OC. Sounds like power supply problem, but dunno for sure. 100ghs per blade sounds right.  Multiple rails on the 12v not good.

Two things:

1) Not all xxxW PSUs are equal, not by a long shot.  I had one situation where a 750W could power two cubes, but another 850W could only power one.

2) You might just have a blade that can't quite make the 400MHz - there's no guarantees that they can OC.  That said, if it's the blade, then I'd check your heatsink and TIM or paste on that one.  What temps do you normally see?

i did not use your script, but used mv for backup also

Ants are running now fine at 400Mhz, drawing together 800W

so that's still 2W/GH and get not even higher temps!

Hey Jeremy,

Can you please do a 387.5 version?

I can do it very easily; but I don't even know if it works or it's safe.  I've used 350, 375 and 400 on my Ants.

A few questions:
1.  Have you run the code on the OP?
2.  When did you receive your Antminer S1?
3.  I see a 387MHz version from zuqka, not 387.5MHz, is that what you want?

I don't know the settings myself for 387MHz.  The ones I'm using were in the original asic-freq file (and checked on the Bitmaintech Antminer FAQ. pdf file) or in the case of the 375MHz, I relied solely on the Bitmaintech pdf file and added it.

Nice tool to help folks.  BTW, I've been using the values from the S1 guide to get to 400MHz:

Code:
        option 'freq_value'     '0780'  #400M
        option 'chip_freq'      '400'
        option 'timeout'        '36'

Anyone know which of the 400MHz approaches is "best?"

 option 'freq_value'     '5e82'  #400M
        option 'chip_freq'      '387'
        option 'timeout'        '37'

Temps are 44/41, hashing at 200GHs.
For my ant these are the optimal setting
