ANTMINER S3+ Discussion and Support Thread

[montyfd]

So the problem S3 was down around 430GH/s this morning and I decided to go over its probably reworked board, the board that had grossly over-tightened screws, but would try frequency change first. 

It had been down to 430 so I tried changing the frequency to check out its effect on hashrate.  In /etc/config/asic-freq I changed to f=225, rebooted and restarted cgminer to get a fresh time duration.  I gave it some time but it came up very slowly only to 420 or so.  And it was a cool morning!  All the other machines were hashing perfectly.  So, I tried again, this time with f=212.5 but again it came up slow and only to 417GH/s.  So, I ripped it apart again.

I was going to concentrate on its ASICs at the hot end of the reworked board, but ended up getting distracted.  What distracted me was that the board had marking in black ink at the far right under the top ASIC (on this board that would be near the intake fan).  Might have been Chinese or a code of some kind.  So, I cleaned that ACIC and the one under it with a spray of automobile brake cleaner such that all thermal paste was removed.  Must be careful with the stuff as it will mar many plastics.  I sprayed those ASICs cleaning around the pins, reapplied thermal compound to both sides of the blade and reassembled.  The brake cleaner removed the notation marks on that blade.  When I reassembled, for a change, I put the bad board on the right side facing the RJ45 connector.

I started it up then ran to the store and back.  Right now the 'difficult' S3, at a frequency of 218.75, after 1hr 20min, has an average hashrate of 443.74GH/s.  The temps are both 40° with fan speeds of 2040/1800.  Time will tell.

Bummer.  Up now over 6hrs and the hashrate has started to drop off.  Could be to an increase in humidity and that the first S3 hasn't seen a similar tailing off of hashrate because its average is over a 12hr period but probably not as it's at 442.24GH/s utility 17 while the problem S3 has tailed off to 437.63, utility 15.  Experience tells me it will continue to fall and tomorrow morning may be down around 420GH/s.  Temps are 40/39 and fans 1920/1620.  The good S3 has 40/38 3180/1920 and the good and questionable S3's are side by side.  What jumps out are the higher fan speeds of the good S3.

Too bad.  1:30AM, checking the problem S3 and its hashrate has dropped to 429.01GH/s after 9hr 55min.  Since I have two S3's, I could take what I think is the bad board and swap it into the other S3 and see if the good S3 then has a falling hashrate - just to make sure which board is bad.  What's wrong with that is that the other S3, purchased from a reseller in the mid-west, runs fine (presently 441.67GH/s) while the problem S3 is from Florida (and that guy wants me to remove the 1 star Amazon rating, screw him, opened the bottom of a box from a good one and put the probably returned problem in and sent it out as new). By morning the problem S3 will likely be down to 420GH/s.  Wonder if it's accumulating errors in an ASIC that then shuts down engines over time.  Wonder if China sends more problem S3's to Florida than elsewhere given that Florida is a problem state like Shanghai crime before 1949.  I'm not a happy camper.

You are where many others have been 2 months ago. There are simply units like that and you probably wont be able to change it. And with 429 you cant complain, they were advertised with 441 +/- 5% if i remember correct.

Hello there,

I have Corsair CX500M psu, is this enough to power 1 antminer S3?
this is the best that I can get here in Saudi and I have no other choice, pls give advice regarding power supply that i bought.

Thanks & Regards,

Yep, that will run an S3 OK assuming you can get all the wattage on the 12V lines, just do not overclock!

received my 8th batch S3 not even one reaches the 500Gh/s range best is around 453
not happy!!!

Yes Sir I wont over clock but I read some forum that stay away from "CX500M" (modular) and better take "CX500"
is it an issue?

Its the type of wire that the M version has thats the issue, you cannot push those wires like you can on the Non Modular version..

I am not conversant with the distinction between the two, but if there were any concerns then that would most likely be because of the amount of wattage that you can actually get from the 12V line(s). Some PSU's do not avail their rated wattage over the 12V lines (which the S3 uses).

Since you already have the PSU, you probably know better what connections you have. You'll need at least two 6 pin PCIe connections and off you go.

Try running it as there is practically NO damage that can be done to your S3 by using that PSU, and see the results. Worst case scenarion is it can not run it well, but that is no loss to you as you already have the PSU. And if the PSU is overloaded, it will cut out to prevent any damage to it.

My S3 is running virtually silent now. l replaced the stock fan at the front (the end with the network connector) with a Corsair SP120 fan blowing in and removed the rear fan entirely. The fan is running at 1920 rpm with 48/48 temps, ambient is 23C.. S3 is overclocked to 225. Maybe won't work so good in hotter countries but here in Uk with summer over should be okay for the next 6 months

As soon as I removed a heatsink I felt I was burning bridges regarding any return.  Hadn't noticed at that point that the box had been opened at the bottom, clear tape slit all around, then resealed probably with a single strip of clear tape along the center bottom leaving the slit sides showing it had been opened.  Then, because I said I wanted USPS, priority mail tape went around the box at its center over the replaced tape on the bottom and some haphazard slaps of priority tape on its side.  I opened at the top.  Kind of indicates he had this dog sitting there and a new unopened boxed S3 and kept the good one shipping the dog.

Right now the hashrate after 18hrs 17 minutes is 419.77GH/s, temps 38/39 while the good S3 from the mid-west sitting next to it has 441.88GH/s, temps 39/37.  441*.095=418.95

And the price with shipping was $511.48.

Swapping the questionable board from Florida into the good unit from the mid-west I notice that the good unit has two QC Passed stickers of different sizes/colors while the slow unit has a single QC Passed sticker large gold.

I would have to agree on 48/48 being too hot for my comfort,

These are in a 26.3C ambient room, apart from the highlighted one which is in my bedroom at 23.5c ambient, S3+ stock clocks/fans etc

Perhaps a previous owner who returned the unit removed one QC sticker.

The questionable board is into the good S3 and both are now up and running.  I'll wait a bit until both have gained some temperature then restart cgminer on both so as to have uptime duration coincide.

[soy]

Of note is that in moving the questionable board to the good unit, on its right side facing the RJ45 connector, and vice versa, the higher fan speed of the good unit has gone to the bad unit and the good unit now has a slower fan speed on the top row.  So, fan speed seems absolutely dictated by the relative hashing board and not the controller board.

The questionable board has been carefully treated with heatsink compound while the good machine has its original heatsink compound.  Perhaps the better heatsinking of carefully applied thermal paste dictates lower fan speed.

A quick check shows that the S3+'s have only a single large gold QC Passed sticker, as did the problem S3 while the good S3 had two QC stickers.

Hello. I have some info that may help regarding power supplies.

Corsair CX600M ____  Melted some  plugs at the PSU connection when overclocked S1's to 393.75. I changed the plugs to a higher quality and it worked. I will run an S3+ at 225.

Corsair CX600 ______Runs overlocked S1's all day long with no problems. Also will easily run an  S3+. Did not try overclocked S3+. Does not shut down easily from room temp.

Corsair CX500M _____Melted some plugs at the PSU connection running overclocked S1's. It will run an S3+ at 225. Did not try overclocked S3+.

Corsair CX500 ____ Will easily run overclocked S1's and S3+'s at 225.. They do shut down if room temp gets too hot but not all of them, just a few.

So for your money if you can keep the room cool, and winter is coming, the CX500's are the best deal. $50 shipped from Amazon or New Egg everyday. And they will run the new L1's.
Also I have 12 S1's all underclocked to 250 and I run 2 on each Corsair cx500. About 350 watts max is all it pulls and the 2 units hash combined is 250-280gh.

Edit.... The M or Modular power supplies are NO BUENO, no matter what the wattage because the plug connection  on the powers supply is a "weak spot" and creates resistance and heats up and melts the plug. No bueno.

I havent tried it but I bet it will easily run 2 S3+'s overclocked, or about 6 underclocked S1's using splitter cables on the PSU..

Hello. I have some info that may help regarding power supplies.

Corsair CX600M ____  Melted some  plugs at the PSU connection when overclocked S1's to 393.75. I changed the plugs to a higher quality and it worked. I will run an S3+ at 225.

Corsair CX600 ______Runs overlocked S1's all day long with no problems. Also will easily run an  S3+. Did not try overclocked S3+. Does not shut down easily from room temp.

Corsair CX500M _____Melted some plugs at the PSU connection running overclocked S1's. It will run an S3+ at 225. Did not try overclocked S3+.

Corsair CX500 ____ Will easily run overclocked S1's and S3+'s at 225.. They do shut down if room temp gets too hot.

So for your money if you can keep the room cool, and winter is coming, the CX500's are the best deal. $50 shipped from Amazon or New Egg everyday. And they will run the new L1's.
Also I have 12 S1's all underclocked to 250 and I run 2 on each Corsair cx500. About 350 watts max is all it pulls and the 2 units hash combined is 250-280gh.

Edit.... The M or Modular power supplies are NO BUENO, no matter what the wattage because the plug connection  on the powers supply is a "weak spot" and creates resistance and heats up and melts the plug. No bueno.

What's your opinion on the Corsair RM1000 ?

Also another FYI. I am using splitter cables on the CX500's to run 2 S1's on each. I use DUAL 4 PIN MOLEX TO SINGLE 6 PIN PCE ($2-3 each) , and also DUAL 4 PIN MOLEX TO DUAL 6 PIN PCE ($6-7 each) . Not one of the splitter cables have melted or even got real hot. You can get them on Amazon or eBay or Microcenter.com.
