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

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

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.

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

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.

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.

Dogie please change your better psu /upgrade for USA buyers

to this

http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1398550839&sr=8-1&keywords=evga+1300

or this

http://www.rakuten.com/prod/evga-supernova-1300-g2-1300w-power-supply-110-v-ac-220-v-ac-input/249973555.html

2 links for the same 1300 watt machine .

Not knocking the corsair you linked but this has more power 1300 watts

better warranty 10 years

and better price. 195 usd

in fact it is lower priced then the oem piece of junk enermax included.

I don't own an s-2 but I own s-1s and the evga will run 3 clocked to 200gh while the enermax struggles to run 2 at 200gh

I like this psu so much I ordered a second

got mine clocked at 212.5Mhz which yields about 1080gh/s consistently. tried 225Mhz and while it shows 1200 gh/s the pool side shows under 1000 gh/s, so there must be a lot of hardware errors or stales or something. without some kind of voltage mod or increase i dont know how much higher than 212.5 you can go. i dont have the settings to try any other ranges between 212.5 and 225 though.

if you do the following the config will save even through reboots:
1. have 4/10/14 firmware
2. ssh into miner (user root, password admin)
3. cd /config
4. vi asic-freq.config
5. comment out current stats (place a # in front of lines that dont have it)
6. add these:
   option 'freq_value' '0801' #212.5M
   option 'chip_freq' '212.5'
   option 'timeout' '40'
7. save
8. you can either type reboot or you can go to the web interface and click save on the miner configuration page.

ADD'T INFO:
- you can combine steps 3&4 as: vi /config/asic-freq/config

I finally got around to doing the calculations myself for the antminer S2 - and so far it looks good (testbench was a U1, which on success menat the code could be applied to the S2 safely)

5002 = 206.25MHz
5082 = 212.50MHz (different from the one above, but both should work fine)
5102 = 218.75MHz

all three meet the requirements stipulated by the above rules and pattern.

5082 is currently giving a hashrate of 1095GH and error rate of about 0.95% after 15minutes. (212.5 is 8.5% higher than the stock speed)

I've got no problems here either, but I've made sure to clean up all those extra cables from blocking the little fan under the lcd screen as it brings in plenty of fresh air for the psu...

If your room is very warm already this little fan sucks! Cheesy

I don't see any problems with the PSU placement or orientation in my case 0_O

Its the psu! Its getting damn hot!!! Shocked

And its definitive a construction faullt. The PSU fan is much to close to one of the asic board. And its getting only already heated air to cool itself.

So i turned the psu so that its fan shows to the right case. Then I stick something into the case so that its open a little bit on the right. So fresh air can come it.
That works fine at the moment.

i have a problem with all of my antminer s2.

it keeps turning off after 15-30min hashing, then it need to be unplug for 5 min before it can be turn on again. anyone having the same problem?
perhaps firmware issue or other known issue ??

btw, how to control the fan?

I have the same problem with the half of my ten S2 miners.
I dont think its a problem of the temperatur, but i will test it.

Please, can somebody help?

If its time based its going to be temperature based somewhere - either the unit itself or the PSU.

I am testing it.

I am waiting now until a miner is going off again, then i will bring it home - and will put the miner direct in front of a window and will wait. (-;

If it is the psu, is there some way to fix this - i dont wanna change the psu...

How did youcome up with that timeout number? I would have thought it would have been in the 60-65 area!
Just curious, I don't have an S2.
