I read FAQ . but i don,t understand .

STEP 1 : Modify/etc/init.d/cgminer 

cnt=0
 if [ ! -f /tmp/cgminer-ntpd-done ]; then                               
               while [ "$NTPD_RET" != "0" ]; do

               touch /tmp/cgminer-ntpd-done                                   
       fi

STEP 2: Disable NTPD client for linux

STEP 3: Re-power antminer

Please explain me step by step.

thankyou so much.

Just received my 3rd S1 today and it is incredible slow (170GH/S) and with relatively (compare to other my other s1's) high hardware errors (0.1 compared to ~.01).

The one thing I will say is that when I received it I could see absolutely no thermal grease / paste leakage at all, temp's don't seem to be issue +1/2c above my other two miners but they do have a pull fan on them.

Any suggestions? I don't want to OC until I'm sure the unit is ok.

Update the firmware to the latest?

On the latest firmware, I did an overclock to 375 and I got around ~190, overclocking to 393 this drops to ~185. Very odd, seems to have a sweet spot of 375. Does anyone have a list of the settings for 380, 385 etc??

[Swimmer63]

Where do you find the firmware updates?

anyone know if the Antminer S1 can solo mine? whenever I tried to go solo, the hash drop from 180GHs to 90GHs and the second blades gives all 32 x in the status.

it works fine with I pool mine? anyone have any ideas?

Your not trying to mine any bitcoins, ha?  Solo mining with S1=shoot self in head.

[boliu]

I am just curious, don't know why it would drop 1/2 of the hash.  anyone know? any ideas/

I overclocked this to 400 MHZ, but how would i underclock it to around 375 MHZ?

clear
cd /etc/config
mv asic-freq asic-freq.BitmaintechFactoryVersion
wget -O asic-freq http://dl.dropboxusercontent.com/s/u8thhaxuksnhlw0/asic-freq.400MHz

ls -la asic-freq*

I've tried this CMD from youtube to overclock to 400 mhz and it worked... but i'm trying to underclock it down to 375, the original instructions to this thread is also not working, MV codes aren't working because there aren't any asic freq files.

Any clues?

jtfr,  375 is still overclocked....  maybe just hit the reset button and go back to the original 350.. then you can just edit the asic-freq file, you will see other freq options commented out in the file...

This thread is for support related discussions of the BITMAIN Antminer S2 hashing device

How to overclock your miner to 400MHz / 205GH/s

The miner will draw 500 - 525Watts after this setting

A) ssh into your miner

B) edit the following file
/etc/config/asic-freq

C) change timeout to 36, freq_value to '0780', 'chip_freq' to 400.

Is the 'chip_freq' parameter just for the reported frequency in the miner status GUI?

Yes that is what is seems to do. freq_value controls the actual frequency.

I don't know what this means or how to do it:
"B) edit the following file
/etc/config/asic-freq"

Can someone dumb it down for me please?

I overclocked my 2 S1 miners but for some reason they are not running at 200GH, I over clocked them on March 9th, do you guys think that this graph looks like a overclocked miners?

That does look a little bit low tbh. What you need to calculate is your HW error rate. If you've oc'd without any extra cooling then it's not going to run at 400Gh/s.

The temperature on one miner is 46, 48 and on the other miner is about 48, 49 for the each board, I'll post pictures when I get home of the miner status.

I am not using additional cooling.

Yeah, it's the heat that's going to do it. I suggest clocking them back to stock or only slightly faster until you get some extra cooling or you run the risk of damaging the chips.

P.S. of course it could be down to your PSU if it's not delivering enough power... what are you using?

the top of this thread says to change new models to this:

however I don't have a '4e81' entry in my file - am I supposed to add the 4e81 entry?

I am using Corsair CS750M R, have 2 PSU's one for each miner.

So I am getting my first Antminer tomorrow since UPS screwed up and didnt get it here today....I digress.

I bought this PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817182082 and it does have 2xPCIE connections, but on the same cable. Is that going to be okay?

No. You gotta have 2 separate cables. No Molex to PCIe either. You can start a fire by using just 1 PCIe cable. It is too much load for a single cable.

Hum... bummer. It does have a 1 x 4+4-Pin ATX12V/EPS12V Connector. Can I use that somehow by buying an adapter cable to PCIE?

Also, the power supply is rated for crossfire. 2xGPUs probably pull close if not more power than the antminer. A R9 290 pulls 336 watts when gaming.
