Good to see other people are having the issue with a blade dropping out. I just dropped the OC down on 2 of my units with the newest FW. We will see if that helps.

use the one from 1024.

Just flashed it. Dropping the OC did not help.

edit: the old FW works fine. Nice job sending out another faulty FW Bitmain. Sad

I would like the bring up the discussion about downvolting again.. it doesn't appear to make a difference measured by the a killawatt at the wall when lowering the voltage.

the watts go down some when you lower the freq., but you should be able to get a better Gh/j with the voltage change... right?

The weird thing though it how loud it was, I know something was suddenly different. I have a few of these, yes, temp sensors, controller board, Hash board. Seems like there are so many parts that will go bad at some point. At some point I guess I can take the case off and get reading with a temperature gun to see if its really hotter than that other side. Seems all my miners act up as soon as I am done the warranty too!

I have an antminer S3 Batch 1 or 2 that is overheating, it runs 60 degrees Celcius on the one side and fan at 9000 RPM, fan running fast and loud. the room is 70F.

Should I take the miner apart and try some silicon paste? Why all of a sudden would this happen to my S3 miner? Very confused.

Thanks in advance!

60C is not that bad. What's the temp on the other side? Is the hot side hashing any slower or showing "x", "-" etc?

BTW 9000 rpm is bogus, max speed for that fan is I think 3000 rpm, but the fan sensors in S3 are notoriously unreliable. Maybe your temp sensor is acting up too.

The issue above has been caused by the latest firmware, I have around 20 machines and the only ones effected were the ones with this firmware S320141126

Revert back to this firmware S320141024 and everything should be ok, and just wait for another release, I was laughing with friends as bitmain are releasing firmware like microsoft release windows, they mess up a little part of the firmware every other release as with this release S320141013 you couldn't amend your pool details Undecided

I have a bunch of new S3's that appear to be dropping one blade... is this the same issue?

Yes this is the same issue, Im very surprised this has not been noticed or mentioned by bitmain yet.

Thanks... thats what I get for doing the bleeding edge.. i should know better. I am still on firefox 21

Thanks, I'm going to switch back to the old firmware now. Hopefully that will solve the issue.

Has anyone noticed an issue with a S3+ where it slows down to ~10% of normal speed (50GH instead of 500GH) after running for a few hours?

I have a S3+ that sporadically does this, and need to restart cgminer to fix it.

The issue is probably either with cgminer, my mining pool (solo.ckpool.org), or PSU. I'm running two S3s on a decent 1000W gold PSU, so I don't think the power supply is the issue.

I'm also using the latest Nov 26 firmware.

Is that a new S3+ and / or have you updated the firmware to the November release?
Ther have been several reports of rigs upgraded to the November firmware slowing down, and the symptoms look like the ones yours is displaying.

this line in my web interface "scheduled tasks"

0,30 * * * * /etc/init.d/cgminer restart

restarts my miner every 30 min. What do I need to replace the 0,30 with to have it restart every 2hrs ?
I'm guessing 120 but I wouldn't bet a finger on it !

I just got 2 S3's to replace some S1's

One is hashing perfectly, the other first climes to about 200 gh/s, and than it drops back down to 10 and sometimes 0.

Anyone had the same issue before?
I've tried another PSU and different pools, but with the same results

How are you powering these miners?

2x Corsair RM850, on each PSU one S1 and one S3

Also, what is the ambient temperature of where they are located?

If you still can't get it working correctly, best to contact bitmain support directly as it's a new unit.

Their new to me, not brand new

I flashed them with the second to last firmware, this seems to help a bit.
Miner status now gives a good gh/s, the pool gives only 50% of the gh/s...

Will I have much of a performance hit if I undervolt my S3+. It is currently running at stock 0725. What setting will it still run stable and have a relatively similar hash rate. Is this recommended for the rig to run coole? I am in a high ambient temp environment. What are recommended settings for a high ambient temp environment?

That is the lowest voltage mentioned in the BM1382 datasheet (the chips inside S3's), so I'd say you are undervolted to the hilt according to bitmain. I am not sure how low the voltage regulators used will go, but I'd guess you'll need to modify some hardware (caps? / resistors?).
As far as I am aware, there are no recomended ambients as the rig will try its best to cool the chips, thus running the fans faster (and louder!). You could try reducing the frequency, but I doubt you'll maintain the hashrate, more like it will drop, and I am not at all sure that will reduce the temperature either.

0725 is the factory setting. So are you saying Bitmain ships it undervolted at the max undervolt setting already?

I can not say definitively that 0725 is the max undervolt setting, but the ~~BM1380~~ BM1382 datasheet lists 0.7v as the lowest voltage setting; it is possible that you can set it lower (and there is nothing to stop you from trying!).
