ANTMINER S3+ Discussion and Support Thread

[muhhentuhhen]

I have G-750 SeaSonic 80 gold powering up 2x S3 miners. After couple of hours, one of the antminer started getting some HW errors. Is this because one of the blades i connected with daisy chain?

1000 errors a day are not too bad.

both have been running for 13h+ now, first one has 57 HW and second 166.

I like to tell another thing, my 2 PCI-E Power cables to S3 were a little hot.
My S3 hashrate was not stable at the rated 441Ghs but was averaging at 420. I ordered thermal paste.
Before thermal plates were arriving, I tried to plug two additional PCI-E power cables to S3.
The Antminer S3 is running at stock clocks 218.75 and PCI-E power cables are cool now.
The main reason for this post is to report that the miners stabilised at 441. Earlier it was 420.
Two thing I'm pointing out,
1. The miners plugged in continuously for 4 or 5 days and seems like it was running-in and stabilised at-last at 441.
2. Plugging the all four connectors even if you are not overclocking will some way help you.

Similar experience here.  S3 clocked down to 212 as it would not stabilise at stock.  Finally decided last night to have a fiddle as I had a bit of time on my hands.  After removing the cover I did the following -

Straightened out the heatsink fins as some were bent close to where the screws were.
Tightened up one screw which was loose on one heatsink.
Pushed the cables to make sure they were seated properly, they all looked ok, no "give" when pushing.
Put the cover back on and instead of putting the cables into the sockets closest to the ethernet port I decided to try the other two.

Hooked it back up, checked the results after a couple of hours and it was hashing at 420.  Decided to put the clock back to stock and it's been hashing at 440 for the last 24 hours!

Really strange as the only thing I felt I really did was swap the cables.  Maybe it just needed a bit of TLC and me stroking its internals made it happy!

OK so I'm back to square one with this! Went back to fluctuating between 380-410 after about 72 hours on stock setting.  Reset it back to 212.5 and it's hashing steadily at 410 now.  

Just had a thought, has anyone ran one without the cover on?  I'm thinking I might try it this weekend, wondering if the controller is getting too warm as its directly above the inside heatsinks and not to the side as with the S1.  I understand the cover is required for decent airflow across the outside heat sinks so I'll either make some sides or blow air from another couple of fans on them.

I have the same thoughts.  Since heat rises, perhaps the whole surface area of the controller PCB is getting the brunt of the radiating/rising heat from the heat sinks underneath it.  It's one of the factors that made me decide to orient my S3s vertically (vertical airflow).  This way, the controller is at the bottom (cooler) and vertically adjacent to the heat sinks and not above them.  Pictures here.

You can use this formula to calculate percentage of hardware errors, I generally consider <=0.3% an acceptable level when hashing at stock.

(HW + DiffA + DiffR) / HW * 100 = %HW

Ooops: HW / (HW + DiffA + DiffR) * 100 = HW%

at atledenin you have the formula inverted  I think but I just woke up LOL

---------------------------------------------------


you are fine  you are more then 99% good.

   take the  formula    hw / diffA +diffR +HW

   if it is under  .005   you are better then 99 percent

926/23,716,864+32,744+926 =   926/23749534 = .000003899    x 100 =    .0003899   that is .9996101 percent good

3 days at customs is that good or bad?.

Have you paid your taxes yet? They may be trying to get a hold of you.

You might want to try to call them, or call the shipping company.

Last status is that they released them today.
They didn't call me or tell me I had to pay anything.

So if they released them maybe I won't have to pay ?

Anyone in the US order miners and they go through Korea? Says Shenzen then next hop was in Korea?

Which Korea? North or South?

It sounds like north, but it is south next to the DMZ. What is UPS thinking?

Quick update on WiFi.  I have five S3s running 100% stable (no reboots) for 4 days at stock clock (daily avg 434 GH/s) on WiFi.

[thehairymob]

I got my pair of miners this week. One arrived a day early on Thursday and the other yesterday. Not being great at reading the manual it took me a couple of hours to get them up and running at full speed. Had them running at half for most of last night think something was wrong. Yeah it was me I plugged the PCI-E cables into the same side. Finally found the prob and now I'm up to full speed. Bitmain you did a great job

I'm thinking of buying 3 or 4 Antminer S3, but right now I'm puzzled about getting proper power supplies for these.

• Such EVGA 1300 G2 is quite pricey, are there any cheaper alternatives?
• Can 3 Antminer S3 be powered by a single EVGA 1300 G2 without problem?
• When overclocking 3 or 4 Antminer S3, how do you solve the power supply issue with 4 power connections each S3 (since a EVGA 1300 G2 only comes with 6 cables)?

What WiFi antenna did you buy? I'm trying to find one on mono price that will fit.

1. yes, see below, but EVGA is good
2. yes, EVGA1300 can power 3 ants at default speed with no problem. It can also power 1 overclocked plus 2 on regular speed or 2 overclocked.
3. EVGA1300 has 8, not 6 connectors. people are sometimes confused because it has 6 cables, but two of these 6 cables have double connectors, so the total is 8 (I have one).
In addition, at least my EVGA came with a jumper dummy already, if you feel uncertain as to how to insert the jumper.

As far as cheaper-corsairCX500 or CX500M is a choice, but you need one for each ant and, since there are only 2 connectors on  each, you cannot overclock it (at least overclock without going against Bitmain recs). While using CX500M, PCI-e cord gets pretty warm (42C), some people feel uncomfortable about it.

I use EVGA1300, CX500M and CX750M (this one has 4 connectors, but is a bit overkill in power, unless you want to run 2 ants on it on regular speed only).

I see that Biodom has already answered, but let me add my comments as well:

Alternatives to 1300G2: very few (like the Seasonic x1250), but I don't think you'll find less pricey PSUs in this class. The 1300G2 is a well-engineered supply; it is worth the money. I have many of them; really the only negative things I could say about 1300G2 are that it is relatively noisy (not as noisy as the miners, though) and that it is only Gold rated, not Platinum. You may want to consider buying 2 smaller PSUs (750W class) that may end up cheaper; each can run 2 S3's.

3 Antminers on a single 1300G2: yes, not problem. You can even overclock them a little.

If you want to use all 4 power connectors on an S3, you'll have to be creative. I have 8 1300G2's; they all came with 8 separate PCIe cables (6 6+2 pin, and 2 6-pin). I am in Canada, so what's in the box may vary from country to country. If you want to use all 4 power connectors on an S3 then you can only power 2 S3's from what's in the 1300G2 box, or find some quality PCIe splitters.

Splitters are generally fine as long as you keep the power below 200W-250W or so (a stock S3 would see about 175W per blade, or 350W total, so it should be ok to use 2 splitters to power the 4 power connectors); you just need to watch for heat buildup at the connection points (crimps points and friction locks mostly). Sometimes you get a cable with a poor crimp or some resistance on the mating contacts which can sometimes create enough heat to actually melt the cable housing and/or sleeving ... something you really don't want.

YMMV, of course, but I've never had the need to use all 4 power connections on an S3. I've played around with dozens of S3's, and all of them had the same overclocking limits, the same HW errors, and the same average hashrate whether I use 2 connectors or 4. I understand that others have had difference experiences.
