ANTMINER S3+ Discussion and Support Thread

[1Neptune]

One of mine is acting up (an S3) and I've set it to reboot every 2 hours:

* 0,2,4,6,8,10,12,14,16,18,20,22  *   *   *     /sbin/shutdown -reboot

Might be simpler as:

0 */2 * * * /sbin/shutdown -reboot

Thanks for the suggestion. Implemented. I freely admit to knowing just enough about crontab to be dangerous.

If you implemented this verbatim you might want to confirm that your Antminer actually has an "/sbin/shtudown" command, I know mine don't, only poweroff and reboot

I've had an ssh session open to the S3 for not quite 24 hours now which tells me it's not actually rebooting, but for some unknown and I don't care reason it appears to have solved the problem and the S3 has continued to hash uninterrupted.

Magic fixes all IT issues at some point. shutdown isn't on S3+ machines.

This should be in your crontab entry:

Code:

0 */2 * * * /sbin/reboot

That is, of course, if the magic stops working and you actually want a command to execute.

I got 2 new antminers today and they have the latest firm ware. this inlcudes under clock freq and under volt numbers . has any one been able to get the undervolts numbers to work.  I keep dropping the undervolt and don't seem to use less watts.

Hate to quote myself but has anyone got a different result with lower volts

I tried 10 different settings and everyone gave me the same power results about 337 watt

I finally went as low as 0599 and the miner did not work it had wacky numbers.  current setting is 0638.  so what am I doing  wrong

note this it the newest model direct from china it arrived on monday the 24th

What is/are the optimal PSU's in the Corsair family to run S3+?

Multiples of 500, 600, 750, and 850
Given your choice, how would you setup 4 miners with any layout of above psu's?

thanks!!

I run a bunch of HX 850 PSUs with 2 S3s each, so in your case I would suggest two 850s for 4 miners.

750 is a bit too weak for 2 miners, so the only other viable option would be two 600s for 3 miners and then a 500 for the fourth one, but why use three PSUs total when you can do with two.

because the closer you reach the max the psu can put out the less efficient it is. its best to keep them around 60%.

True, but it's negligible for any decent PSU and wouldn't cover the expense of more PSUs needed to run at lower utilization.

For HX850 the difference between 50% load (max efficiency) and 90% load is 1% at 230V or 2% at 115V.

Maybe you should consider something like a SuperMicro PWS-865-PQ, they are 80+ Bronze and have 4 6-pin PCI-E leads from a single rail. Average retail around $145 each.

[raskul]

i like to have plenty of headroom.

i have 2 x s3 on 1600EVGA 80+ gold.
and 2 x s3 on AX1200i 80+ platinum.

be wary with bronze rated PSU's they are far less efficient.

Hi. How can i reset miner to defaults? I messing up with wifi controller and accidentally disable wan port. Now i'm stuck with wifi connecting to my router. No ip  assigned to wifi if. So i can't reach web interface. Trying to hook up debug port but it disabled by bitmain .

[smit1237]

So ive managed to reset miner via serial console.

Hi guys, can someone send me a S3+ coupon if they won't use them  please ? If you want i can send you 10 mBTC for it. My user id is lanfeusst@hotmail.fr
Thanks

I will send you a PM.

[SunnyIgor]

is it possible to have more than 3 pools on antminer s3?
and if so please show me how

If you need more than 2 backup pools you may want to look into more reliable pools instead. If you're doing load balancing or something similar, you're better off dedicating certain machines to a particular pool and using the other 2 as the backup.

e.g.

Miner A: Pool1, Pool2, Pool3
Miner B: Pool2, Pool1, Pool3
Miner C: Pool3, Pool1, Pool2

[SunnyIgor]

I have 1 pool rental site, only alive when rented.

Second pool is nice hash, with a price minimum

only one pool most of the time, no backup

[MoreBloodWine]

I have some coupons I can send, PM me your username and what it is your after, they expire the end of Nov, Ty.

Guys, what's BITMAIN shipping charges to US - let say for pair of S3? And are there any paid customs?

Thanks in advance

No import costs to the US. Shipping cost for two S3s is ~$140 to West Coast (not sure if it depends on location).

[sepehr]

Guys I have one S3 that worked fine but now suddenly not mining at all.

both mining cards are red blinking like this, I have included a copy of control board also. what you say?

[smit1237]

Try that:
Login via ssh and issue commands:
killall cgminer
 cgminer --bitmain-options 115200:32:8:17:243.75:1306 -o stratum+tcp://poolurl -O worker_name:worker_password
and paste here what it output to you.
Also show us ouput of command dmesg
