Title: Please Help. S3 Hashing dropping for no reason???
Post by: ChineseSavior on December 17, 2014, 06:35:58 AM
Okay well I have 13 s3 running.

Randomly 1 2 3 etcc will just stop hasing down to like 50ghs or will half and run around 200-225ghs....

I have tried spreading them through different circuts, still have the same problem. This problem is geting very annoying and I have to cycle my setup once per day. Not fun for a mine I want to run auto pilot.

Please advise. I have an asus rt-n12 router. Could too many connections be possible? I am running 4 switches offf this router totalling 14 machines now.

I have also email bitmain. This is driving me crazy.

Sounds to me like your mine is under powered... What PSU's are you using?

Another (practical) option would be to put a good timer between your PSU' and the outlet, setting them to cut off power for 1 minute every 24 hours or so...

PS and please put in a few ($10-$20) buks for a good (pro. Cisco 24 port) switch...

Just see - for instance: http://www.ebay.com/itm/Cisco-Catalyst-WS-C1900-24-Ports-External-Switch-Managed-/141492020675?pt=US_Network_Switches&hash=item20f194e5c3

Sounds like you upgraded to the new Nov. firmware.  Known problem with it.  Downgrade the firmware to the Aug. firmware if that's so.

This problem also happens with the October version (which was preloaded directly on some batches).

A fix/workaround was to add a scheduled task that restarted cgminer every 30 mins.


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

1. Never use different PSU's or even different rails from the same PSU on the same blade of an S3 (or any miner for that matter); and,

2. Are these all on 1 circuit/fuse?

This has been happening on 2 of my units since I installed the new bios, one unit seems to have bricked as of yesterday, I changed the other unit to a older bios.  I seem to be running stable on antMiner_S320141024.bin for the last 6 hours.

The Oct. firmware renders the reset button inoperable, try the Aug. firmware.

I don't think that the version matters, I just flashed with antMiner_S320140826.bin and my reset button (S2) doesn't do a damn thing and I still don't have chains showing up in the lower portion of the screen:

i will be looking at the auto reset pnce per hour as a workaround. i am inclinded to think that the firmware isnt the issue similar to what the last gentleman was saying. i am scared to do firmware upgrade remotley as i am not on site and would be depending on someone else.
