 I got mine to freq 250. Took out the intake fan and used a fan I had laying around.  . I replaced the thermal paste for all the chips and only had enough left over for one of the heat sink in the back. You can see the temp difference of replacing the thermal paste. I used Antec F7 since I didn't want to wait for the MX-4 to arrive in the mail. The room is about 23.3C and the fan rarely goes above 1700. interesting, but why taking out the intake fan? |

256.25 ----- I do not have the code for this.
Thx, anything above 250 IMO is asking for trouble, 250 itself is thinking of talking to trouble. Don't know if I want to really mess with 250 though, but if 237.5 holds well for the next 24hrs with no X's, I may just do 243.75 and call it a day as the saying goes. I did notice on my refresh after the initial post (before this) that all looked good on the miners except for a single x on the third miner. I rebooted it, did one fresh and wont touch / check on it til I get back from my 3pm appointment. I chalked that x up to a hiccup on the new freq since sometimes another reboot is all you need for them to settle after OC'ing. I have one S3 that has a single x on 237.5, however, it is still better (464-465) than on 218.75, so I leave it with one X in perpetuity. It (miner) did not "complain" so far (>10d). |

First, drawing 180W through a 6pin is dangerous and I wouldn't recommend it to anyone.
You might be activating some sort of protection on the PSU (they are very safe and programmed to shut down immediately when things get too hot or overloaded), so the best test would be just to plug in the 3 PCI-e cables and see how things go.
Good luck!
The 6-pin is differentiated from the 8-pin by only 2 ground wires. If the PSU is single rail and uses quality cabling it shouldn't be an issue, especially if you use 3 or 4 cables. I added Startech PCIe splitters to each PCIe cord. It works fine on EVGA1300 and cords are not even hot when at 237.5mhz. Naturally, both ends shall go to power the SAME board. |

I have 8 Antminer S3 coupons.
Value:= 0.075
Looking 0.06 for each coupon.
Valid up to 16August You can use also for S3+ and S1 Upgrade Kit. This is why you still have them on August 14th...dream on .06 nobody is that stupid  getting free money is stupid? Some people have truly unrealistic expectations.... fair value of these coupons is 0.005775 BTC. They were provided in lieu of miners underperformance (441 vs 478GH). |

someone offer antminer s3 for .53btc
is that good price?
too low. lemon? |
|
|
|
It's actually cheaper to sell the S1 and buy an S3+ rather than go the upgrade route.....crazy!!
I always suspected this to be the case, so I sold all my S1 just as I ordered/was getting S3. 0.58 BTC price wise is at the level with others, but Sept 20 shipping date is unfortunate (too far away). S3 is pretty energy efficient and reduces risk (in case your machine is a rare bad one). |

Seems like I got lucky with my two from Batch 6.
One is running stable 500+ gh/s at 250 freq. (46c, 45c)
The other stable at 490+ gh/s at 243.75 freq. Above that this one gets one chip X'd out. (44c, 45c)
Should I consider re-applying thermal paste on these to bring temps down or consider myself lucky and leave it alone?
leave the good thing alone...if it works, it does so more or less stably. I don't even want to try 250 that much, pretty content at 237.5, perhaps will try 243.75 later |

I just noticed this on the bitmain site: https://bitmaintech.com/files/download/antMiner_S320140811.binThe notes just say "added advanced frequency" which means there is an extra tab for overclocking in the miner configuration page...just flashed now thought I would give a heads up to you all  Edit: in order for the frequency and firmware to work and not come up blank, I used the "save settings" box when flashing the firmware, then after the flash is complete and the miner has rebooted, go to the miner config/advanced tab and hit apply on the frequency you want (it defaults to 237.5 and no idea why 100 is in there), then hit apply on the main miner config page to be safe, then reboot the miner...works for me! so, basically, on current miners (at least B4-7) 237.5 is a de facto default. I thought so.... |

For some strange reason 2 out of my 5 Ant Miners require re-flashing every day to bring back up to stock speeds of 441 GH/s they appear to run stable for about 12 hours or so and then both just fall to circa 420 GH/s. I have tried everything, replacing the thermal paste, swapping around the PSU's, factory restart, reboot etc. The only thing that helps (For a short period of time) is if I flash the device again and again every 12 hours or so.
Has anyone else got any thoughts on what else I could do? Or do I just have 2 faulty units?
I've observed something similar with hashrates dropping to around 420 , however I also see hash rates of 460-470. Basically there's a 10% variance both + and -. I now have 4 S3's and besides the faulty one now doing 229 the rest is up and running at 427 to 444. I also have a dragon 1 Th/s miner and also this one shows a variance of up to 8% both up and down. My observations after a week are that the hash rates somehow go up and down simultaniously. So if the Antminers are "slower' the Dragonminer seems to be slower as well. Thanks, I guess I will just live with it, I suppose 40 GH/s is neither hear nor there anyway these days. if you got multiple, it will average out: I also have one "underperformer" at ~415, but the other five perform above grade: 464 (one) to 478 (four) on 237.5, so average per miner is currently 465GH, which is good. However, it all would still go sour if BTC continues to tank. |

S3+ for sales shipping starts on September 20th or earlier
omg, 5 weeks with no sales of S3's......
i wonder what they changed to make them + ?? revised hardware design makes the S3+ more stable at higher frequency. sounds good. they looked at the thread here and decided to use a better thermal paste |

Results of today's BITMAIN announcement:
1) Existing S3 owners basically received a 0.1 - 0.2 BTC increase in the value of their individual S3's
2) New ebay scams: Sudden increase in the number of S3+ units for sale.
3) cynical B1 owners now have the new S1- model.
i don't get point #3. point#1 is correct, so what? |
|
|
|
Ok who is pre ordering the S3+'s today? Besides me.
resellers stand to make a lot of money on ebay since 37 days are easily at least 0.25-30 BTC worth. add 0.25 to 0.58=.83, so everything in hand now below that will sell. |

When your done OC'ing (editing the file) it says to reboot the system.
When back at the command line in PuTTy, can you do like a sudo reboot to reboot the system ?
I don't know in Putty (could be the same), but in Terminal, if you are still at the root prompt, type reboot, then hit enter/return. |

How much power your S3 uses on CX750M or CX500M?
at 237.5 one S3 uses 402-406W at the wall
at 218.75 another S3 uses 375W at the wall
according to kill-a watt at ~116V (US)
These numbers seem higher than what's posted, maybe the difference between bronze and gold or platinum PSU?

AM is back on business @1,2btc/Th and in massive quantities tho
That's true, and IIRC FC said his goal is to drive the competition into unprofitable territory. As in he's going to undercut everyone so badly that they all go out of business. It will be interesting to see how it plays out--I look forward to AM's new gear. Where do you see it (AM gear), apart from rocket box and XBTEC? I see only github announcements on their facebook? Re Bitmain-they will adapt to whatever competition shows. right now-not much, hence higher prices. This should increase prices in the aftermarket (good for those with S3 already). |

Consider Fermi's paradox-there should be tens of millions of civilizations in Milky way galaxy alone, yet we have no indication of such civilizations ever existing in the past or today. In particular, some stars in Sun's category (G) and slightly dimmer (K) had existed continuously since 4 billion years BEFORE solar system was born, and we now know that some of the planets around such systems are similar in size and density to Earth.
Consider that bitcoin has a mysterious origin that seemed to bypass everything that was established beforehand. Bitcoin is like invention of the wheel, it had to come up all at once, or never.
Consider that one of the theories of the Great silence (Fermi's paradox) is that there is a Great Filter, which NO civilization has bypassed yet. It is possible that the Great Filter is either behind us (good) or ahead of us (we are doomed).
Consider that either debt-based financial system that is prone to self-desruction OR Bitcoin constitute a Great Filter for further development of our civiliztion.
If financial system is the Great Filter, I would posit, then it would indicate that Bitcoin-like technology NEVER appeared elsewhere or was defeated/circumvented by the debt-based systems. A glimpse of exactly how debt-based system future plays out was already shown in 2008. All you need is another episode, and it's over.
If Bitcoin is the Great Filter, which is less likely in my opinion, then we will see how it will play out in the next 100 years or so. A remote possibility: maybe one of the gigantic Bitfury datacenters will develop self-organization and proceed to accommodate more and more resources toward bitcoin related calculations, shorting the development of civilization as we know it going forward. This is even less likely scenario, in my opinion.

So the dilemma compensation wise so far :
1) to order the current 4.5 TH sp 30s at a reduced rate in Sept for your compensation (15% off?)
2)receive cash or btc compensation for your current unit(s) since we paid 4500-5000 and current price is 3900 or so which averages to 15% off say $800
3)wait for the details on compensation for October batches (I would assume maybe 15% -20% off?)
its a tough call another 4.5TH Sept unit at around $3100 is a good deal, but a 5.5 TH unit at the same price even though its a month later is a better deal right ?
what do you all think.
It's only an ok deal if they meet their specs. or not, if Bitfury will continue bringing 20-30PH to market every two months (the equivalent of 4000-5000 SP-30). Where does Bitfury get their cheap electricity? This only works if they are getting electricity at a rate less than the rest of us, where that rate is the same or greater percentage than the efficiency difference of SP30 v. Bitfury. Can they really have such an advantage in free juice? This sucks. Why didn't we predict this? Hindsight is 20-20, we should have imagined that a low end semiconductor Chinese factory with 200 people could easily set up to beat 15 Swedes or 15 Israelis no matter how clever they were. Looking back, I don't know why nobody predicted this end to the mining race. I don't think its a surprise the Chinese are know for flooding other markets with cheap plentiful hardware so I saw this coming , the thing that threw most of us for a loop is that when china was banning BTC you would think that would affect bitfury and other Chinese manufacturers like bitmain right ? but no they just pump out more hardware than ever. I still can't see how they can keep pumping out 20PH each month though with their inferior hardware, at some point they will have to improve their DC hardware and what will they do with all those existing 55Nm chips ? my existing question stands though, i postponed for now, but your situation might be different. Any insight into why ? I don't see any other hardware out here on the horizon better than what SP-TECH has right now even with the slow corner sp30s at 4.5 TH, the only reason to postpone hardware purchases i can see are : 1) you are already invested in New Antminers or have existing KNC hardware you need to ROI on first and are waiting for the KNC compensation package 2) you anticipate huge increase in difficulty that make any hardware purchase after September a waste of $$ 3) you are expecting some new hardware right around the corner to the tune of 10 or more TH per unit that makes SP-30's quickly obsolete. thanks in advance 1. yes I am (antminers, which is a totally different type of machine, as you know), but it is not the reason. I want to use hosting for SP-30, but hosting is either expensive or still building. 2. I have no idea, but I already have one Sp-30 on order, so seeing how it would work out might be beneficial. Nobody wanted to sell me their GB  3. it is possible, but unlikely, and even if there will be one, it would be quite expensive or with unreliable delivery (KnC) |

Should we all change the thermal paste on our miners? Should I go buy some before my miners arrive?
Noooooo (re prerequisite), I say that it is more likely that you mess something up rather than help yourself (on average). Buy paste (just in case if you have a real problem)-it's $7.8/4g (MX-4 at amazon), or GC-extreme-$10 |
