Hi Guys I just got my antminer s3 and having big problems. It's only mining at about 250ghs and gets around 75% hw error. I am using a brand new Corsair CX500 and have also tried with my Corsair HX850. I have changed the thermal paste on all the chips. I have flashed it to latest firmware. I have very stable internet connection. Anyone have advice for me? After 5min: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi62.tinypic.com%2F2psln39.jpg&t=665&c=RjcH_g8fXr-7rw) After 10min: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi61.tinypic.com%2F28vaza.jpg&t=665&c=UZD35t593zeW2w) HW error: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi58.tinypic.com%2F262qnmq.jpg&t=665&c=CW2anFR3IhWxSQ) Sorry, you are an RMA candidate!

Problem re-starting S3?
I've had two Antminer S3 running for a few days now. No problem setting them up or getting them going. They have worked to spec.
However, today I had to shut them off, and when I turned them on again they would not start mining. I cycled the power numerous times and rebooted. They would come up but not mine.
The only thing that works is this: start them up. They sit there running but not mining. So I login through the web interface and go to "System" and "Startup", then hit the "Restart" network button, wait until it comes back, and then "Restart" cgminer. Then they start mining and continue to work smoothly.
Any comments or advice?
I point out that both units have behaved exactly the same.

Do Reset to Factory Settings. If not working again update firmware.

Hello! I'm going to have two antminer s3s I will never upgrade and I just want a PSU that can handle both Antminer's overclocked.
I heard my EVGA 500W 80 PLUS psu won't work as the 2 pci-e cables are daisy chained? I can't even see if they are or not. I may return that PSU and try to get either..
EVGA 1000W
or
EVGA 1300W
The cheaper the better.
I was also thinking of getting two CX600 or CX750
Please help!

Thanks for your reply, allcoinminer, but that doesn't help. I updated the firmware for one of the two units, and they're both still doing the "not mining" thing until I restart the network and the cgminer.
My guess is that it's some timing thing with the network --- something times out in the first network setup when the antminers are first booted, and it doesn't time out after the antminer operating system has settled down. Maybe the name server? I've got them doing the network setup with DHCP.

The S3's are all venting out of the enclosure. The only problem is they cannot pull enough air into the room. A simple whole in the wall will suffice to fix the problem. Also, to the OP, your insulation will still be very beneficial to keep the radiating heat from coming through the walls. It just would have taken some extra math to learn that 16 S3's have more CFM than your window AC can move. Who knows....Maybe just removing the window barriers next to the AC would be best. I agree with this. get an AC that will push more air than your S3's combined The overall misunderstanding is in how an AC system works. The AC unit is not pulling the hot air from inside the room to the outside. What it is doing is a fan is pulling ambient temp air from inside your room, and moving that air across a coil that is cooler than the ambient air. The colder coil absorbes some of the heat energy and removes some of the moisture via the beer can affect. The ambient temp room air that has gone through the coil gives up some of it's heat into the coil, and left some of it's moisture condensed on the coil and is returned to the room drier and 8-15 degrees cooler than it started. That particular AC is a closed system and doesn't move any air from inside the room to the outdoors, or from the outdoors to the inside of the room. The hot air you feel coming out of the AC on the outside is the "heat energy" collected from the inside air through the cooling coil. On the outside, another fan blows the outside ambient temp air across the now hot coil, pulling some of the heat from the coil then recirculates the reduced temp coolant back to the inside to soak up more heat energy from the ambient inside air. I found a good video that illustrates how it works on youtube. http://www.youtube.com/watch?v=6OU7WHgJ_cYAir from inside the room is blown across the cooling coil, then back into the room, this keeps the pressure of the room static or unchanged. Now with the miners doing what they do, how you currently have them configured, is attempting to pull cooler air from inside the room through the heat sinks, picking up heat energy, and exhausting that warmer air outside the sealed room. With no air being let into the room (not through the AC as previously assumed) and all of those miners trying to pull air out of the room...creates a vacuum or negative pressure zone, that's why the door slams shut since it opens to the outside of the room which is now a positive pressure area relative to the lower pressure inside the room. If that door was hinged on the other side of the jam and swung into the room, the miners would be sucking the door open when pulling air into the room. Your concept is pretty good, however, you should try sealing the miners inside the room entirely. Seal off all the exhaust holes, and mount the miners vertically so they are sucking cooler air up from the floor since colder air sinks, and exhausts out the top as hot hair naturally wants to rise away from cooler air. Then your room will be back to a static pressure area, where the cooler air coming out of the AC unit sinks to the floor, gets pulled up through the miners heat sinks and the warmer air naturally wants to rise out of the miners. In this fashion, your using the miners fans to help the already natural convection current, of cooler air down, and warmer air up. I have my miners running in a small room, the ambient temp of the room about waist/chest high is 78-80F. I have my miners mounted vertically, pulling in the air from down by the floor ~74F, (2-3 degrees cooler than midzone), when it comes out of the miners, its much warmer ~94F(warmer than midzone) and rises to the ceiling where it's apx. ~82F. If you mount 3 digital thermometers in your room, you see the thermocline, or temp difference between the floor, mid, and ceiling height. Give it a shot...your miners will never run cooler unless you put em in a freezer.

PSUs are less efficient and will burn out sooner if you run them at full load. My advise is to get yourself a gold or platinum certified PSU around 1000-1200w. Overclocked at full tilt (350 MHz) you will pull apx 400w from the wall per miner...so your looking at ~800w for the pair. The conversion from 120V AC to 12V DC isn't perfectly efficient, so some energy is lost as heat(why PSUs have fans). If you have a decent gold/plat PSU your looking at 87-92% efficient...so if your pulling 800w from the wall your miners are only consuming 696-736w...the other 104-64w are lost as heat. The less efficient PSUs (uncertified, bronze, silver) put out more heat, as the conversion is less efficient. You also want to have some headroom on the PSU so your not pushing it at the max 24/7( = burnout & replacement costs). I only use gold/platinum certified Corsair PSUs (wish I got $ for the free advertising) because they are pretty much tanks. I'm running 4 Corsair RM1000 PSUs (gold cert.) and they have a 5 year warranty if I remember correctly. They worked great on the S1s (I had 6 S1s overclocked on 3 PSUs...2 each), and the S3s. You can do your own research, and this isn't exact ,but 80% of the rated load is normally approaching the point where efficiency starts to decline because of the heavy load/heat buildup. You could also run an additional single blade(half an S3) if your not overclocking any of them...overclocked that would be using 1000w and would be incredably hard on any PSU. My advise is pay the extra for a reliable strong PSU. You also pay a little more for fully modular, but if you have alot of gear, it keeps clutter to a minimum....may not make a difference to you if your only going to ever have 2 miners, then modular doesn't matter so much. Just remember...additional cables in the way reduces airflow and increases temps...maybe not to the point of making an impact...the rule holds true to life (ie...computer case cable management). Good luck and happy mining.

I was able to seperate the above frequencies into smaller incremental steps, but I have no idea how to calculate the "reg. value" or the "ideal delay" for them. Anyone with a little more know-how than myself willing to help out? I know a few other people in this thread were looking for something like this as well, and any help at all would be appreciated. Thanks!
Adjusting the S1 formula based on S3 ASIC spec I was able to get following register values (and timeout). Use the settings below at your own risk! Clock_Freq | Register value | Timeout | (chip_freq) | (freq_value) | (timeout) | 100 | 0783 | 40 | 103.125 | 1007 | 39 | 106.25 | 0803 | 38 | 109.375 | 1107 | 37 | 112.5 | 0883 | 36 | 115.625 | 1207 | 35 | 118.75 | 0903 | 34 | 121.875 | 1307 | 33 | 125 | 0983 | 32 | 128.125 | 1407 | 31 | 131.25 | 0A03 | 30 | 134.375 | 1507 | 30 | 137.5 | 0A83 | 29 | 140.625 | 1607 | 28 | 143.75 | 0B03 | 28 | 146.875 | 1707 | 27 | 150 | 0B83 | 27 | 153.125 | 1807 | 26 | 156.25 | 0C03 | 26 | 159.375 | 1907 | 25 | 162.5 | 0C83 | 25 | 165.625 | 1A07 | 24 | 168.75 | 0D03 | 24 | 171.875 | 1B07 | 23 | 175 | 0D83 | 23 | 178.125 | 1C07 | 22 | 181.25 | 0E03 | 22 | 184.375 | 1D07 | 22 | 187.5 | 0E83 | 21 | 190.625 | 1E07 | 21 | 193.75 | 0F03 | 21 | 196.875 | 1F07 | 20 | 200 | 0782 | 20 | 206.25 | 1006 | 19 | 212.5 | 0802 | 19 | 218.75 | 1106 | 18 | 225 | 0882 | 18 | 231.25 | 1206 | 17 | 237.5 | 0902 | 17 | 243.75 | 1306 | 16 | 250 | 0982 | 16 | 256.25 | 1406 | 16 | 262.5 | 0A02 | 15 | 268.75 | 1506 | 15 | 275 | 0A82 | 15 | 281.25 | 1606 | 14 | 287.5 | 0B02 | 14 | 293.75 | 1706 | 14 | 300 | 0B82 | 13 | 306.25 | 1806 | 13 | 312.5 | 0C02 | 13 | 318.75 | 1906 | 13 | 325 | 0C82 | 12 | 331.25 | 1A06 | 12 | 337.5 | 0D02 | 12 | 343.75 | 1B06 | 12 | 350 | 0D82 | 11 | 356.25 | 1C06 | 11 | 362.5 | 0E02 | 11 | 368.75 | 1D06 | 11 | 375 | 0E82 | 11 | 381.25 | 1E06 | 10 | 387.5 | 0F02 | 10 | 393.75 | 1F06 | 10 | 400 | 0F82 | 10 |
JakeTri -- I would like to thank you for your work, I know the request wasn't mine, but I was wondering about this the same as la7eralus. I'm interested in how you calculated those Reg. values. I would like to break this down one more level and be able to find the nitch between 250 and 243.75. I looked at the Reg. values and attempted to convert from HEX...but that didn't look even close to right. So...i'm interested in how you calculated them. If you could explain, or point me to some documentation that explains it...i would be grateful. I have done a few Google searches...but found zip. Any direction you could give would be appreciated.

I'm sorry if this was already covered...so Ill keep it brief. I have an AntMiner S3 that's a rockstar. I overclocked it to 250 MHz, and it was hashing right along at 505-506 GH/s, even after 2-3 hours. Temps were great 39C-41C, absolutely no X's on my chips. This morning, I wake up...take a quick peek before heading off to work and it was sitting at 490GH/s, and it was still sitting at 490GH/s (rock steady) when I got home from work 10 hours later. After work I calculated the HW errors and i'm sitting at 0.21%(pretty good unless I missed the boat). Now I know that's nothing to complain about...and I'm not trying to. I'm just wondering if anyone else has experienced a similar situation and has any kind of explanation or trick to get it back above 500. Thanks.

i'll trade you for mine that doesn't go above ~400GH ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) but if you're worried about 10GH just restart cgminer.

I started with the bit layout for freq_value and from there you can calculate the chip_freq. Bit layout for the freq_value is as follow: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs24.postimg.org%2Fftzr6e7w5%2Ffreq_value.jpg&t=665&c=RYt2lkmPLkksBA) OD can have values between 0 and 3 R can have values between 0 and 31 F can have values between 0 and 127 BS can have only 0 or 1 From page 6 of BM1382 spec ( https://www.bitmaintech.com/files/download/BM1382_Datasheet_v3.0.pdf) you get: NR = R + 1 NF = 2 * (F + 1) NO value from OD value (see Table 4 from same spec page) Fref = Fin / NR Fvco = Fout * NO Fout = Fin * NF / (NR*NO) So Fout is "chip_freq" and can be calculated based on valued from above ("OD", "R" and "F"). BS select "high-band" or "low-band" (see page 7 from BM1382 spec for valid freq values for each band). chip_freq = 50 * ( F + 1 ) / ( ( R + 1 ) * POWER( 2 , OD ) ) For timeout I used following formula: timeout = 4000 / chip_freq I suggest to calculate all 3 Fref, Fvco and Fout and make sure all 3 value are in range described on page 7 for the band specified by "BS" value. EDIT: Here is an example: freq_value = 1306OD = 2 R = 1 F = 38 You can compute the rest as following: NR = 2 NF = 78 NO = 4 Fref = 12.5 Fvco = 975 Fout = 243.75BS = 0 and all 3 values for Fref, Fvco and Fout are in range for Low-Band.

Ummmm....thanks?. You made my brains hurt! Is that even....I don't know. Apparently I've got some studying to do. I better just read the manual from the beginning. I'll see what I can figure out.

I setup 4 S3s in my office room for testing and configuration. They were all hashing away fine after the test so unplugged them to relocate to more permanent location in the adjacent room on the same network and wired router. My router obviously reassigned each one a new ip, but i just looked a the DHCP list to find them and typed in the new ips and three of the four logged in just fine. My problem is the fourth will not log in. The password screen comes up and i type "root" and then it goes to this screen:
/usr/lib/lua/luci/dispatcher.lua:448: Failed to execute function dispatcher target for entry '/'. The called action terminated with an exception: /usr/lib/lua/luci/sauth.lua:87: Session data invalid! stack traceback: [C]: in function 'assert' /usr/lib/lua/luci/dispatcher.lua:448: in function 'dispatch' /usr/lib/lua/luci/dispatcher.lua:195: in function </usr/lib/lua/luci/dispatcher.lua:194>
And also now when i type 190.168.1.99 for the setup after the password screen it just goes to Page not Found . The fourth one is still hashing as normal as reported by my pool. Im afraid to reboot again since everything is hashing normally, but would like to be able to access all miners for future OC. Can anyone offer some suggestions? Or tell me what other info you may need me to provide.

My problem is the fourth will not log in. The password screen comes up and i type "root" and then it goes to this screen:
/usr/lib/lua/luci/dispatcher.lua:448: Failed to execute function dispatcher target for entry '/'. The called action terminated with an exception: /usr/lib/lua/luci/sauth.lua:87: Session data invalid! stack traceback: [C]: in function 'assert' /usr/lib/lua/luci/dispatcher.lua:448: in function 'dispatch' /usr/lib/lua/luci/dispatcher.lua:195: in function </usr/lib/lua/luci/dispatcher.lua:194>
And also now when i type 190.168.1.99 for the setup after the password screen it just goes to Page not Found . The fourth one is still hashing as normal as reported by my pool. Im afraid to reboot again since everything is hashing normally, but would like to be able to access all miners for future OC. Can anyone offer some suggestions? Or tell me what other info you may need me to provide.
Disable DHCP and set the IPs manually is the solution. If not working Reset with the small button in the front side of your antminer S3.

I'm thinking of buying 3 or 4 Antminer S3, but right now I'm puzzled about getting proper power supplies for these. - Such EVGA 1300 G2 is quite pricey, are there any cheaper alternatives?
- Can 3 Antminer S3 be powered by a single EVGA 1300 G2 without problem?
- When overclocking 3 or 4 Antminer S3, how do you solve the power supply issue with 4 power connections each S3 (since a EVGA 1300 G2 only comes with 6 cables)?
- What's the power draw of an Antminer S3 when running at 250 MHz?

1) yes - but generally it would mean using a server power supply which is louder and less friendly to use in a small setup. THE EVGA 1300 is a great unit at a good price 2) yes, even at ~380W each you are left with over 150W of overhead capacity on the 12V rail 3) either get a good quality splitter or just use 2 connections per unit. AFAIK using all 4 connectors doesnt provide much realworld benefit but might be slightly safer for the pcb traces 4) closer to 380-400W
