[Guide] Dogie's Comprehensive Bitmain AntMiner S2 Setup [HD]

[dogie]

No its not better at all, and don't post a bad recommendation just because you've put a referral link in it. It runs at ~43 dba rather than 20 (SILENT), is 4% less efficient and is rated such that its max rating is actually its peak. The Corsair unit does the reverse and has another 100W of headroom.

 Those are not referral links I get no money if some one buys from those links.

You list the evga in your link above at 329.99 dollars  it goes for 194.99 dollars.

 
 The corsair costs 329.99 in your link  That is a 135 dollar difference.  I love your guides and I am not trying to make a dime off the  Evga.

 I am asking you to reflect the current 135 dollar difference  in price between the Corsair and the Evga .  Both psu's are under the sound level of the fans in the antminer.

the two reviews above are for both psu's    ..   At the equal price of 329.99 I agree with you get the corsair.   at 194.99 vs 329.99  the evga is better.

Prices change day to day, so my recommendation has to be long term. I'd personally pay $100+ between the two, they are literally worlds apart. You'll be calling in that 10 year warranty in not long if you try and run the Evga @ 1300 24/7. Why do you think it needs to be cooled with double the airflow at the same capacity?

Fair enough .  I do not a  have corsair ax1200i
I have a sea sonic 1200 watt (clone of the corsair) on order
‹
 I do own two evga's  1300

 I will run the evga for 1 week 24/7
when I get the sea sonic I will do the same test.

the sea sonic is available at amazon for 290

I am running 3x s-1's here they are.

Has anyone managed to get their unit to not beep when not mining? Mine still does even with the option turned off.

[imar2014]

Nope, mine has the same issue. I have a  B2

Guys -- a noob question: 

I have a Corsair 1200i that I'd like to replace the S2's Enermax PSU.  However the pinouts aren't compatible ... can't plug in the motherboard plugs from the S2 into the modular connection of the 1200i.  Is there an adapter I need to use?

Thanks!

You need to use cables from your Corsair 1200i. I'm guessing you just disconnected cables right from the PSU, am I right?

This. Remove all the power cables that were in the S2 and start again.

[dogie]

Tested my unit with one intake totally blocked (by mistake) and it runs fine, temps didnt exceed 58 on the hottest boards.

[bitmanaus]

hey dogie, love your guides, always top notch quality

I made a few modifications to my S2, i found my power supply was drawing in too much warm air from the boards so i turned it around and cut a nice neat whole in the side of my case to allow it to bring in air, i was going to change the power supply to a 1250w i had lying around but one of the pci-e pins on the mainboard was badly damaged so i decided not to risk it.

I did however change all of my fans out (one was damaged in transit and couldn't get a matched replacement) I put some high speed Yate Loon fans in and they work a treat, I have them running direct off the enermax power supply using an enermax peripheral cable and a Bitspower X-Station Fan Board to allow the fans to run full speed all the time, the fans are an improvement over the factory fans, much quieter and the temperatures of the unit stay down much lower.

Thanks for your awesome guides and pictures, its your guides that inspire me to rip things apart and have a look

Cheers

Thanks for the suggestion!  I was hoping to just disconnect the S2 cables from the Enermax and plug them into the Corsair.  No go on that -- S2 cables don't fit into the Corsair plugs.  Bummer.

Based on your suggestion, I'm assuming that the Corsair cables will plug into the S2 -- haven't tried it yet but will do so and report back.  Need to take all the modules out of the S2 again to pull this off since the cables do go under the modules.

...stuff

Please don't ask for tips in my thread, even I don't have a tip address.

fixed - sorry to tread on toes!

also, currently trying out 6206 (215.625MHz) on a U1, and expect to implement it on my S2 after a few more minutes of confirmation.  212.5MHz gave me 0.75% hw errors while 218.75MHz was about 2.02%. 

hopefully 215.625MHz will be around 1-1.2% error rate and thus about the highest stable speed for an antminer S2 (batch 2, external DPS-2000 PSU)

Have you set the U1 to the same voltage as on the S2s?

no i haven't - my main use of the U1 is to make sure the code isnt wrong and causing too high, low, or impossible a frequency and thus hardware failure.

6206 worked fine on the U1 (1.730GH average) and is now implemented on the S2 problem free (1098GH, 1.136% hw errors) after 1.5 hours of operation. Presumably there's a ~1180W power draw to go with it, but my 208V PDU is not metered. Temps range from 48-55 degrees

still waiting on someone to identify which resistor on the S2 would allow pencil-modding to raise the voltage. The chips and arrangements are quite similar to the S1, but not identical enough that i can firmly state 'it is resister Rxx'.   I would love to be able to slightly bump up the voltage on some of the hashing boards to see the effects on hashrate, but I assume if temps get much higher than 55C (board 1) the error rate might really start to jump up.

I still think that these units could handle 1280GH/1500W if the resistors were just set just a bit differently for a few extra millivolts to reduce the amperage and allow a little further tuning into the 225-250MHz range  (frequency 0981 would give 250MHz, or about 1280GH)

You'd have more like 1600+W and every few GH after that would be at 1.5-2W per GH. Maybe its worth it for some, but its only going to be worth it for a month or so before you're going to be downclocking and wanting to reverse your mod again.

I've got a hosted S2 which suddenly failed. The hosts said:

Removed all of the blades one at a time. Unpluged and replugged all power. tested all power. attempted factory reset.

It looks like the TPLINK has a corrupted card or is dead?

Have you heard of this as a likely fault?

Sd card corruption is common, you need a copy of the image and flash it with the image flashing software. There are some links around page 88 in the sales thread. Will take them 10 mins and is really simple.

[railzand]

wow thanks so much

[dogie]

wow thanks so much

No problem, it's a known bug that can occur during power cycles. Minimise turning off the unit where possible.
