I recently upgraded my s3's firmware what is with the new voltage setting underneath the freq setting? I run mine at 250mhz and have been doing so for 3mos now without a issue. What can this new voltage setting do can it give me more speed? I rn the on Corsair HX1000 PSU's So i got watts to spare

I've just put down my findings on using the voltage setting in the new firmware to OC (or UC) here: https://bitcointalksearch.org/topic/s3-bm1382-overclocking-with-voltage-setting-883197

Just got a new S3 and have no idea how to get it mining. I put in my pool information, connected miner to my router and it doesn't mine. Any ideas what to do next?

Make sure you set your DNS servers. Sounds like you aren't getting name resolution.

same questions here https://bitcointalksearch.org/topic/m.9608517
but other direction...

it seems the voltage changes are not really applying at least downwards...

i answered the voltage question on the previous page of this thread

You should have noticed by now that your response contains a fundamental error, no wonder people have not taken notice of it! aka

To add the frequency you will add this to /etc/config/asic-freq

The S3 frequencies are not set via the asic-freq file (at least for the latter firmware), rather via the file /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua (see instructions here: https://bitcointalksearch.org/topic/m.8370071 )

Have you changed the IP address to DHCP?

How do you do that? I don't know much about networking. Not sure what I've done now. I clicked on DHCP and can't get in the menu at all.

Once you change to DHCP the unit will get a new IP address, so you need to check your network for the new IP address and log onto that via the UI.

I have found sometimes with mine I had to restart it completely and/or "save and apply" to get it to catch on to what it is supposed to be doing. I also have experienced a weird thing where it insisted on putting stratum+ before my address even though it was no longer valid. Very strange.

It doesn't seem to have a connection to the internet. I have it connected to my router. I believe that is the problem. It is just a standard cable modem with the router built in.

===VOLTAGE SETTINGS===

The Very first post in this thread contains the following

Quote

I have tried 275MHz and 300MHz, and were no-go since the chip voltage in the S3 is set at 0.784V.

Since we can now mess with voltage, the question is how do we set it?

well lets take some things into consideration.

#1 Raising your voltage beyond safe limits can quickly damage your equipment, so this is the most finicky and potentially dangerous part of the overclocking process.

Now there is a WONDERFUL piece of info about our chips here
https://www.bitmaintech.com/files/download/BM1382_Datasheet_v3.0.pdf

That gives us some clues as to how to set the voltage.

Since .784 volts is the default and the chart shows no gain in GHS over .80 then .80 would seem to be the logical step up.
that will raise out Watts per GH to 0.702.

Now lets look at frequency.

at 275 the GHS is 17.33 (just like the chart shows for .80 volts) so we can surmise that to overclock to 275 mhz we would need at least 0.80 volts

The paper also shows that the MAX recommended operating voltage is 1.1 (dont go there)

I am not making suggestions as to what you should do. I have not tested this myself. Based on the information available i think that 0.80 volts at 275 mhz SHOULD work (if you can keep it cool)

To add the frequency you will add this to /etc/config/asic-freq

Code:

config 'asic-freq' 'default'

        option 'freq_value'    '0a82'  #275M 
        option 'chip_freq'     '275' 
        option 'timeout'       '15' 

        option 'freq_value'    '0982'  #250M 
        option 'chip_freq'     '250' 
        option 'timeout'       '16' 

        #option 'freq_value'    '1286'  #237.5M
        #option 'chip_freq'     '237.5'
        #option 'timeout'       '17'

        #option 'freq_value'    '0882'  #225M
        #option 'chip_freq'     '225'
        #option 'timeout'       '18'

        #option 'freq_value'    '1106'  #218.75M
        #option 'chip_freq'     '218.75'
        #option 'timeout'       '18'

anyone familiar with openwrt's implementation of opkg? apparently on the S3's "OPKG Update" isn't working.

When I run it i get the following:

Code:

root@LabS31:/# opkg update
Downloading http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/Packages.gz.
wget: server returned error: HTTP/1.1 404 Not Found
Collected errors:
 * opkg_download: Failed to download http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/Packages.gz, wget returned 1.

I checked the path at http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/ and Packages.gz does not exist.

Anyone have a clue how to resolve this?

Code:

root@antMiner: #-> cd /etc && cp opkg.conf opkg.conf.bak && vim opkg.conf

Change "src/gz barrier_breaker http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages" to
"src/gz barrier_breaker http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/packages"
And then:

Code:

root@antMiner: #-> opkg update

It works well. Hope to help you. Cheesy

You are looking at the wrong file. Frequencies are set in the GUI and the file that holds these values is no longer the /etc/config/asic-freq file, but rather the file /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua (see this thread if you want to add to the freqs' list https://bitcointalksearch.org/topic/m.8370071)

tks mate , but :

pb.default = "18:218.75:1106"

pb:value("18:218.75:1106", translate("218.75M (S3 default)")

is still set to 218.75

The file may say that 218.75 is the default value, however, you definitely have 225 set as the current value.
To set the the value, do it in the GUI, ie browse to Miner Configuration then click on Advanced Settings. You'll see a drop-down where you can choose what value to run at then click Save & Apply after that.

tks, works fine now
