ANTMINER S3+ Discussion and Support Thread

[fatsailor]

I've a couple of S3+'s and S3's.

I've been playing with overclocking (Mostly with the S3+), and here's what I've noticed for the S3+'s:

Clock                   GH/s  (ghash)      Power in watts (at wall)
------                  --------                 ----------------------------
250                     492                      500
237.5                  470                      360
225                     451                      355

If I overclock on a 20amp/120v line, I can run 4 S3+s.  For approximately, 2TH/s.

If I don't overclock (or moderately do so) on the same line, I can run 5-6 S3+s. For approximately, 2.35TH/s - 2.92TH/s.

To me, it seems like the best bet is to moderately overclock. This of course ignores the cost of the S3+s and PSUs.

I'm curious what others think?

how to do the overlock in s3? has a softwere for this? eh too dangerous (ha risks of burning the machine?)

thanks for atention

I think that 500 should be a 400.   I've read a couple people who did similar tests and it ranged for 250 clock (503GH/s) from 374-402watts.

[fatsailor]

I know that 250 runs about 500 watts...and that three S3+s will cause a EVGA 1300 to shutdown.

Is there a fairly simple way to create a redirect stratum address, perhaps one that is on an internal computer on my network, that I could point multiple AntMiners to. 

The point being to easily change the mining pool address, worker, password, and difficulty, at just one place, and all miners would then switch to the new address?

Or if there is an easier way, is there a way to mass update settings on a multiple AntMiners all at once? 

I attempted to answer this earlier, but my reply was deleted. I'm unclear exactly why, but perhaps it was because I named and linked to the resource I was recommending.

I know at least one site that allows you to lease out your mining rig operates their own proxies, allowing you to set up your preferred pools and make changes on the fly, and see nice charts of 72h performance. If you desire, you can also allow others to pay you to use your miners in an automated fashion. Because you're always pointed at their proxy, there's no effort involved on your part in swapping settings, etc, just set all the miners up to point to the same place.  It makes for a handy way to control all of your miners at once, as long as you like to have all of your power directed at a specific pool.

It's easier than setting up your own proxy. It took me around 5 minutes to get up and working with them.

+1 ...same conclusions here...

I am running one S3 @237MHz = 478GH STABLE ...and the other @225MHz = 454GH STABLE ...best settings for them ...

Both Batch 1 ...latest FW and cgminer 4.6 ...750W PSU's...

Have been experimenting with 200 to 250MHZ range ...more than a month...

Happy mining,

ZiG

Must be nice, out of six S3s, only two are comfortable at 225 MHz (one of which still averages below 450GH/s).  Guess you're just the charmed guy!

[ruslan4040]

Hi All! I have 2 S3 and both overclocked to 250, but one of them loses speed to 460-450gh 2 hours after launch. I changed the firmware, changed the thermal grease (lost x) did reset, reconnect the power connectors. Nothing helps. What to do?

[CHAOSiTEC]

Just to warn you guys, EMS can be extremely slow... im still waiting for my 3x S1 upgrades, send on the 16th, and so far, last update is

Sep 16, 2014 11:29 pm - Despatch from Sorting CenterChina EMS SHENZHEN

just a heads up...

[soy]

Yes, this is better.  Before it barely got up to 435GH/s with the low hashing board on the right side when looking at the RJ45 connector end.  The right side is the top chain and generally has the higher temperature and faster fan.  In this case it had lower temperature and slower fan than the lower chain.  So, taking the end plates and their fans, swapping ends and moving the controller board, put it back the way it was shipped, the questionable board on the cooler side.  

Almost right away the average went above 441GH/s and has remained above 440GH/s for the last 3h 23m and is presently 442.04 tho the utility is only 15.  No hardware errors in that time.  It was started as the afternoon cooled.  It remains to be seen what happens tonight as the humidity increases.

Oh well.  A minor improvement over yesterday morning and there's even greater humidity as it rained.  This morning the problem S3 is hashing at 434.15GH/s.  A nice improvement over finding it down at 419GH/s in the AM.  Guess I'll just have to settle with this hashrate.  The good S3 immediately next to it is at 440.85.


...1½ hrs after running /etc/init.d/cgminer stop, it restarts automatically after a minute or two, the hashrate of the problem is up to 442.18GH/s(avg).  It restarts with a fresh Elapsed duration.  So, I'll schedule this to run middle of the night and again in the AM.

[Moria843]

Just got my first two S3s. They're both running at about 455 GH out of the box, but GH.io is showing that one of them is sending about 200,000 duplicate shares per hour. Anybody ever see this before and know how to fix?

[philipma1957]

I know that 250 runs about 500 watts...and that three S3+s will cause a EVGA 1300 to shutdown.

 then that is a defective s-3+  my s-3+   that will run at freq 250 and keep the gh at 500gh use 390 watts on a platinum psu.


 I own a gold 1300 evga and it can run 3 at 243.75 no worries  1110 watts.

Since I only have 1 s-3 + that runs at 250/500gh I can not see if 3 will work on the evga.

 I suspect no.  as the evga ran  3-s-1's using 1215 watts   and doing 600 gh for about a month.  then did not want to continue at that clocking. I had to back off a bit.

Okay, I see this problem has been address in message #482 this forum with cgminer-avg-monitor script.  Kudos.

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?

PM'd ya

One of my new S3+ shows 0 temp and high fan speed. Has someone an idea were the sensor is located? Still mines flawless. RMA would take too much time and efforts.

[mindtrip]

Just called on a problem blade they were offering to do an RMA but phone call dropped

The LM75A is in the center of the ASICs, halfway between the upper and lower rows.  I'd guess a connector fault and would try swapping ribbon cables to see if the problem changes chains.
