ANTMINER S3+ Discussion and Support Thread

[hochiroku]

when i login and check stats of miner i can see the reject rate is ridiculously high. would it effect my mining?

Post your actual rates for hash as a comparison.

whats worse is that i tried to overclock it and n ow im hashing at 102 Ghash?
can someone please help me out of this mess?

You must select the new frequency, apply, save, restart/reboot the miner for the frequency changes to take effect otherwise it runs very slow.

i was doing it manually through asic-freq. all sorted now. i selected 500 but still hashing at 400 and the discarded rate is still ridiculously high
i can also see the avg hash rate is like 310

Crikey, there's no frequency! Never seen anything like that.
Also, you forgot to obscure your details....
Also, why don't you use:

stratum+tcp://stratum.btcguild.com:3333

as your mining URL as opposed to the http:// .... ?

Under miner configuration. Click advanced and select a frequency.

Little bit off topic... how's your experience with leasing S3? Wondering if possible to make a bit more BTC's then with mining BTC directly.
Tnx

I lease my miners at 0.000000029 per MH per DAY calc say on average at curent diff you make 0.00000001834 Per MH a day

I'm having a problem with an S3 I got from Florida.  It consistently runs slow.  I've just replaced the thermal paste, front and rear of both boards, and a single ASIC is malfunctioning.  I'd like to know how the o's are positioned relative to the actual ASICs.  For instance, looking at the miner from the RJ45 port end, is the top row of o's the right board?  And then is the first o the ASIC closest to the RJ45 port then progressively around so the last o in the line is the ASIC beneath the ASIC closest to the RJ45 port.  If this is the case then does the lower line of o's have the first o representing the top ASIC at the far end of the left board, farthest away from the RJ45 port?  If not, how?  Thanks.

I note that the hashing board on the left while facing the RJ45 port seems to have been a problem.  The screws from the board to the inside heatsink were grossly overtightened to the point 2 were almost impossible to remove.  When I got the heatsink off there was more thermal paste than on the the other hashing board.  The other hashing board has paste that was more dry.  This second with the over tightened screws had fresh paste.

I just worked on the second, over tightened screws board again.  Cleaning the ASIC of paste on its pins and closing it up, it's been up a little over 5 minutes but running slow, 432.03GH/s(5s) 418.33GH/s(avg) but all ASICs are showing o's.

The new thermal paste seems to have helped.  What is helping more is reducing the wifi load.  With the storm I had put the living room Ant1 on wifi and disconnected the cat5 connection.  The backroom Ant2 can only run on wifi.  The combination of better thermal paste application, the cleaning of ASIC pins, and the reduced wifi load with Ant1 back on cat5 now allows Ant2 to be hashing at 439.11GH/s(avg) and slowly climbing.  Then again it might be that the temperature and humidity back there is now 83° and 42% rh.

how much time is it rented?

They do.  I would say mine is rented at least 50-75% of the time.  You can see the rental history here: https://www.miningrigrentals.com/rigs/491
I also charge a little less than ftoole though.

Heads up guys, if you update your CGMiner beyond what it comes with, bitmain will deny you any future RMA

Source: They denied several of my S1s back in the day when I applied Kano's fix.

Hi bobsag3,

Your above lines are not true, we sincerely support RMA for any tech issues except for overclocking.
We really appreciate Kano's work.

Even if it were true, you could always just flash them with stock firmware before doing a RMA.  Sounds kinda fishy to me.

Bitmain,

How soon are you then going to release a proper firmware with the latest cgminer in it?  If I remember correctly, you sorta promised somewhere in here to have it in two weeks and that was, I think, over three weeks ago.

Give it a shot, and please feel free to use me as a referral: http://www.miningrigrentals.com/register?ref=126

ok setup 12 ants to use it.  Will give it a try.  Thx and used you are refer.

Thanks for clearing that up. It seemed a bit far-fetched and clearly bobsag3 has a history with Bitmain.

i remember when S1 delivered by BITMAIN was overclocked. and on that case RMA didn't support.
I will dig to find it. but in original thread there were few issues like that. .

Had my stuff rented 3 time already back to back. turning up the price each time ;-)  The ants don't seem to mind it at all.

Thanks for the tip.  Anyone looking to purely ROI should have a look at this.

What is the best moddiff for s3

[Moria843]

B8 order in, need to connect wireless. Will pigtail below work for S3?

I want to make sure it has the right connector.

You are right. I've ordered 4 such pigtails. And 2 antennas. ) My order has already arrived in Russia and passed the customs.

May I ask what determines load?  I have two Antminers,

#1 using cat5 connection and its wifi connection disabled has:
loads of 2.70, 2.56, 2.51,
hashrate 441.03,
DIFF 354,
Fan/Temp 3000/41 & 2220/41 room
Temp/Humidity 83°/-%;

and #2 at some distance running via wifi has:
loads of 1.62, 1.47. 1.42,
hashrate 440.80,
DIFF 367, 
Fan/Temp 2040/40 & 1860/39,
room Temp/Humidity 80°/39%.

So the first has loads 147% higher than the second?  Both S3's at stock frequency.

The biggest load is on an Antminer is cgminer, because it does all the work.
Installing the latest cgminer (which does NOT void your warranty) will, it has been shown, reduce the load by a significant margin.

I am actually surprised at your results, I would have thought the wifi connected antminer would have a higher load than the cat5 connected one, and that it would be reflected in the Diff that has been allocated by the pool, aka I would have expected the cat5 connected ant to have a higher Diff. Could you check your pool-side speeds and see if they reflect the GUI speeds? Also, what are the DiffR numbers for each? (PS. I'll expect a slightly higher DiffR on the wifi connected ant, assuming they are connected to the same pool)

Do you know by chance how much of a load reduction is realized with the new CGMiner?  We've ordered a number of the new S3+ units and am wondering what PSU wattage would be needed for 1 unit pending they've rated it with the older version. I was planning on 500w PSUs for singles... Perhaps 400s would work?

Thanks!
