Have you tried your mods on the new firmware peka?

Pekatete, Thanks for this thread. It tried it on 2 S1's upgraded to S3 with Bitmain's kits and 1 S3. They all seem to start mining significantly faster after any clock change with the voltage setting of 0750 than with the original (blank) setting. It also seems to make them more tolerant to higher clock rates. My S3 did not 'like' clock rates higher than 225 MHz. It is now stable at 231.25 MHz. I did not get a chance to make a comparison of power consumption. I went back to the Oct 2014 f/w on all of these antminers.
Cheers

You are welcome. The voltage setting seems to work brilliantly with the S1 to S3 rigs and S3+ rigs but not very well with S3 rigs ... must be something to do with the regulators they used. As for firmware, I agree too that the best to use for setting voltage, in my experience, is the Oct 2014 firmware. Happy mining!

Hi all, I'm new to this board and enjoyed being readonly here for some time. Owning a S3+ that suffered degradation to 50KH/s I did an upgrade to latest Firmware. Currently the rig is doing well: at 0,75V and 250MHz: - Running for 21h now
- Average Performance of 500.80 GHz/s
- 806 HW Errors (0.0097% of Diff1#)
- Temperature 41°/42°C
- no performance degradation yet
Kind Regards Chris

what is the filename of the 10/24/2014 firmware I see alot of references to it but no one names the filename and it is not sorted by date on the antminer site.

the new firmware sucks antMiner_S320150109.bin is causing crazy HW errors now I am getting 50+ HW in 1 hr and the past i was getting like 8 for 24hrs+ This stuff is garbage.

okay so i tried going back to a earlier firmware antMiner_S320141013.bin and i get this when i try to enter the miner configuration or status page Ugh... looks like i am stuck with this new crappy HW error firmware it tells me to modify voltage but then wont let me into the configuration page XML Parsing Error: not well-formed Location: http://192.168.1.99/cgi-bin/luci/;stok=2ea100503df2fb12cd124476c867299a/admin/status/miner/ Line Number 348, Column 34: Modify voltage and Save&Apply, then need to Power off and Restart -------------------------------------------------------------^

Read the opening post on how to fix that error.

I dont see anythinig in regards to that, do i need to putty in ? and if so what do i change the voltages to? Can i change them via the new firmware configuration panel (instead of putty) then PSU reboot it then apply the older firmware? What is the best firmware? everyone says october but no one gives a filename When it failed with that error i put the new firmware back on , but my issue is degredation is hashrate and high HW with this new firmware.. ugh

October firmware was removed from the bitmain site, but it is the one with the error on the configuration page. The OP has instructions on how to fix the error, however, if you've already reverted then that may be moot. There's also a link in this thread that I posted where a user shared a link to the above mentioned firmware, but like the fix to its error (in the OP), all you need to do is read the thread, it is not that long!

ahh much better So while still using the new firmware heres what i did entered default frequency setting set voltage to 0720 save & Apply Reboot via PSU switch Logged back in restored that 10/24 firmware from that link Unchecked keep settings. Logged back in setup DHCP reset frequency to 250mhz left voltage alone And what do you know right back to 505GHs with 0 HW errors damn their new firmware I dont think i will be upgrading that again. So what version of cgminer is this 10/24 firmware using?

Good you've got back up and running to your heart's content! I am not sure what version of cgminer ships with that firmaware, however, you can get it by logging into the rig via SSH and entering the command: That will show you the version you are running.

Here I was thinking this doesn't work when I thought I'd try it on my other S3+. Setting to 262.5 (because I don't dare go higher without extra pcie cables) I am getting 540Gh/s out of it @ 40 Celsius and 0.0062% error rate. My other S3 can only muster 460Gh/s at 231.25Mhz any higher and the has rate drops and I get an x on one of the asics

not sure if this implicates anything but just wanted to throw it out there The c1 uses a stock setting of 250mhz @ 0760 voltage setting Does that tell us anything in relation to the S3 and S3+'s? This is the default bitmain setting for the C1 just some food for thought

hello my question what the correct syntax the voltage settings
0.75 v = 0750 ? on s3+ web interface ?
and what the default voltage 0.72 ?
sorry my lame question ?
thanx

Yep, that is the syntax, 0.75v would be 0750 The default setting for the latter firmware, I believe, was 0000 i.e auto voltage but the base voltage prior to cgminer 4.6.1 was (again I believe) 0725

With my 20140804 S3+ Build, changing the Voltage in the Advanced Settings does absolutely nothing.
First I verified the wattage from my Kill-A-Watt and any setting 0.75 0.80 0.85 resulted in the same reading.
Then I decided to measure the core voltage for each BM1382 mining chip. So I took apart the Antminer. I didn't have access to the bottom layer of chips without removing the heatsink so I just measured the voltages of the top chips. They were as follows
VDD1=0.781 VDD2=0.766 VDD3=0.770 VDD4=0.825 VDD5=0.775 VDD6=0.778 VDD7=0.824 VDD8=0.780
Decided to measure on my other blade on the other side and got
VDD1=0.822 VDD2=0.778 VDD3=0.781 VDD4=0.774 VDD5=0.777 VDD6=0.773 VDD7=0.773 VDD8=0.824
So I changed the voltage parameters in the settings, up and down and each and everytime I got the EXACT same voltage readings on the chips. Changin the frequency doesn't change the voltage. Bitmain cheaped out and used very cheap parts thats why some cores run at 0.822V and some run at 0.766V due to the tolerance of the resistors/capacitors.
I tried 2 different firmwares. Dec 19th and Oct 24th and same results.
Also noticed how badly assembled some units are. I am lucky these capacitors are connected in parallel and the bad seating doesn't affect their operation.
