BITMAIN Antminer S3 support and OverClocking thread

[tbolt]

Bitmain S1 upgrade kits..


Well after pulling my hair out for a couple of hours it dawned on me that you need to update the firmware with the latest S3+ ver.
At stock 225 freq its running at 450 GH/s  pulling  385 watts from a very high grade server power supply.
Want to let it run for a while before I try to ramp up the freq.
Stock form temp is 39C
will let you know how I make out with overclocking, If I get it to 500  I'll be happy.

Does your Power Supply provide all four PCIe connectors per Antminer
or just two per miner?

Just curious..

Looking forward to your update on the OC.

One of my S3 fails while overclocking; Indeed a chip crashed, and the overall hashrate decreases.

oooooooo oooooooo
oooooooo ooxooooo

Do you know how to find the 'x' chip? right/left board, and chip number; I have a small voltage difference between DC/DC converters, fixing this and the thermal glue may fix this issue. But how to find the right one?

Welp

5 days in and my antminer s3+ caught fire!

This literally just happened like 5 minutes ago.
Rig went offline, went out to see what's what and try and give it a power cycle, no go.. So I swapped the psu for a brand new one and went to turn it on and was met with a huge cloud and smoke and an adrenaline rush. (all cables correct etc, I have 9 others from the same batch running on the same corsair rm1000 PSUs with uptimes of 5 days, no overclocking involved)

Does anyone have info for UK bitmain support?

Just tried calling the UK number above and its just a mailing forward address.

I already had this issue on a GPU; The SMD ceramic capacitor turns to fail in a short circuit state. If the PCB is not damaged, replacing the capacitor will fix the issue; if the PCB is damaged this is an other story...

I used the method above to overclock my S1s, but I thought you could change the freq from the advanced menu in the S3. My first S3s still in the mail. Do you still have to SSH to overclock the S3?

I would like an answer for this as well. I have used the "old" S3 SSH overclocking method to OC my new batch 8's but when I try to SSH and type "!wq" it doesn't save as it should. Another method maybe?

Try just !w and see what it says. What are the file permissions? When you !wq you don't get a chance to get any feedback if there is a problem writing to the file. Also check the time/date of the file to see if the write is actually occurring.

Nope. Didn't work

What are the file permissions? Is the date/time updated when you use !w?

I'm using 4 connections per unit.
at freq 237.5 they hash at 485GH/s with a 1 degree rise in temp to 40C and power went from 385 watts to 410 Watts.

so far so good

No it's not. Unsure of what you mean by file permissions.

try :wq

What causes this to happen? I'm pretty worried about leaving any more of them unattended right now

You CAN NOT overclock the S3 via SSH in this way, only to add extra values if you want (but the file name and format is different from that of the S1); you gotta do it via the Advance tab.
Also, you are WRONG! Need to type wq! (with the exclamation after the letters!)

I didn't notice the !. Try the commands separately: :w then :q. After :w you should get a confirmation of a successful save.

I still use the vi editor. With PuTTY I hit ESC to get out of vi and then :wq

my antminer s1 upgrade kit isn't working. I think it has something to do with the fact that it is showing 4 chains under miner status, any help is greatly appreciated:

[adzam323]

I had the same problem with my antminer but I reinstalled the firmware then it worked 

[buysolar]

I had the same problem with my antminer but I reinstalled the firmware then it worked 

Ya I tried re installing the latest firmware several times. Still doing the same thing. Still not hashing and showing 4 chains.

[moug]

get it from the Bitmain site: antMiner_S320140826.bin
save to desktop and reflash worked for me.

make sure you uncheck the box that say's save current settings or you'll be wasting your time.

I just received my 3 S3+. I have 2 corsair hx850 PSU's. Will they be enough to run all 3 at stock speeds and would their be any wiggle room to OC them a bit?
