Topic: BITMAIN Antminer S3 support and OverClocking thread - page 11. (Read 158144 times)

Here's how I understand it, the share number is the result of the share you sent in to be counted towards your attempts if you are with a pool. It signifies the level of difficulty you found. So if the difficulty level was less than that 14,598,073,804 , you would have mined a block with that share. Today the number is a lot higher, if you see a number bigger than 46,684,376,316.8603 , there should have been a block created by that machine. This is why pools work. For an example, your machines together might find a share that big every 3-4 months, if we were stuck on this same difficulty or lower that whole time. Put more of those odds together and you can find block daily to even earnings out.

After I changed the power supply on my one S3, it got so much cooler in the room I have it in. Thanks to overclocking it, it's warmer again, and the power supply wires are perfect.

I will note I got the unit secondhand, and not one clue what batch it is. It has been running just great at 250mhz, putting out 503.07 GH/s average for the day. The one issue with the explanation here is !wq did not work with the vi that is on my machine(vim pointed to vi). After escaping from the input mode, ZZ got it saved and exited. I imagine a lot of people could be confused by that.

Replace !wq to ZZ and there's no issues
(!wq is in the first post, they are incorrect)

Is there anything useful to know about the "Best Share" number?

I have 2 S3s, after 2 days one has 14,598,073,804 and other has 1,712,428.

You can also upgrade the firmware to the latest which will have the Advanced Settings page.

no, I'm not sure.
If you're referring to power consumption though, I don't pay power.

I ultimately settled on a clockrate a bit lower than max as max would sometimes drop off at lower than optimal..

Correct more hashrate = more BTC
But are you sure your calculation is complete? please replay

If you have the Advanced Settings page, then no need to SSH into the rig, just change frequency then click Save & Apply..
If you do not have the page, then YES, you'll need to SSH into the rig and edit the file manually. Google for Putty, it is one of the common software(s) for SSH'ing ...

question..

there is the software for... SSH?

and then there is the modification under ADV SETTINGS...


are BOTH adjustments required in order to overclock
or just one will suffice (i.e. ADV SETTINGS will override without SSH..)?

one of my S3+ runs at around 500
the other one is around 410..  <<< not sure if I SSH's this one.. or if it is necessary..

why would I want to underclock... overclock = stronger hashrate = more bitcoins

Under-clock it, not overclock it

Good. Same thing for C1.

It worked!!! thanks!!!!
now if I can overclock the C1 miner

Check if you have an Advanced Settings tab under the Miner Configuration tab, if so, you need to click on it and set the frequency there. Latter firmware also does not read frequency settings from that file ... rather another one.

It can run higher.  I have a couple running at 262 and the others running at 275.  You have to actually edit it in a couple of areas. 

what do you mean?

I've ssh'd it to run at 250.. isn't that all that is required?

It's possible you just have to insert the frequencies.

I have 2x Antminer S3
Kernel Version   3.10.12

not sure of batch or how to check..

I know how to do PUTTY > ssh > modify the # comments etc.. did for S1's I used to own.

trying to get these S3's to overlcock at 250/250 freq

when I release comments on the 250 freq setting and save > exit > reboot

it will save, but when the system reboots it runs at maximum 225/225 frequency...

why is this?



is it even possible to exceed 225 on all s3 units? or some are hardwired to not exceed?

You've had quite the experience. I got my s3 from a different guy.  The latest firmware hasn't caused any issues for me (knock on wood) and it's been 12 days without reboot with minimal HW.

I also had issues with my C1 rates. I set it to 243.75 freq and 0730 voltage and it seems to like that setting the most.

and also get your hands on the october firmware I had some serious issues with the newest firmware dropping hash rate and such. Its a pain in the butt to downgrade form the newest firmware as well so if you installed the latest firmware make absolutely sure you check out the threads on steps to take before trying to downgrade, a cpl people bricked their machines i found you have to reset the stock voltage thenreboot via psu, then when you apply the old firmware make sure you uncheck the keep settings box. otherwise all hell breaks loose. And if your not careful you can brick it. Makes a very expensive hurricane proof  paperweight

ebay guys name was dringdahl0320
I left him a real nice review haha

He had a whole rack of what was suppose to be s3+'s
After i seen i had issues i looked closer at the image and he had the exhaust from some miners blowing into the intakes of others probably the ones (s3's) he sent me.

Fortunately my case fell under the buyer protection as they were sold to me as S3+'s and he sent me S3's otherwise i would of been stuck with them.

in addition once i sent them back he did the refund via echeck which caused like a 10 day delay in getting my money back. And we all know what delays in the mining business mean.

Fortunately i found a guy selling brand new S5's for like $425 I made him a best offer of $380 and he agreed. Should be in my rack this week. brand spanking new from his last presale batch 4 - full bitmain 90day minus shipping time warranty so in the end I came out right on track with better power efficency now what to do with the other powersupply , i bought 2 when i ordered those damn S3's.

Looks like I will be ordering another S5 haha

Been watching the s3+'s and there were many this week that sold for around $100 so kind of glad he tried to scam me and i got to send them back as i gave him $380 for 2 with shipping figured in.

at any rate hope you didnt get the ones i had they are damn near paper weights. They would only run at 218mhz without X's popping up and even at 218 they had crazy hw Rates if i would of bben stuck with them i was going to tear them down and reapply the thermal paste, known issue with early batch S3's plus looking at the images the way he had them lined up they were probably cooked. But from what i read alot of the earlier S3's had slopy thermal paste so bad it was all over the chip connections causing chips to short, and then some post i read some chips were missing thermal paste all together, which would cuse that asic to overheat and X out. Alot and I mean alot of the early S3's from what i read had thermal paste oozing out of the heatsink holes and peole were having lots of issues with chips malfuntioning because of it. all my S3's are batch 8 and up through the S3+'s my last one i bought , they released the C1 1 week later. I finally bought a C1 and they released the S5 4 days later, but likie the S3's never buy the first batch My C1 is batch 2, and my S5 i got coming is batch 4

Now My c1 its a pain in the butt it hashes all over the place up and down like a roller coaster, check the C1 discussion thread nice images of my graph up and down up and down haha. Then sometimes when i reboot it a entire board will X out. I have to do a PSU reboot to fix that. But i still got 60 days warranty on that but i swear it keeps doing it and its going back. I am not impressed by its stability, and its a batch 2 from what i hear the C1 batch 1 had some issues. This may be a C1 firmware issue but I am keeping a very close eye on it and its warranty date

Now just crossing my fingers that my S5 being Batch 4 is issue free

so in summary if you bought those S3's from that guy and cant send them back, try tearing them down and reapplying the thermal paste.

Good Luck



 
 

What was the ebay seller's name?  I wonder if it was the same guy I got my S3 from...
