Edited contab to run the following every hour. Im expecting an increase in hashrate.

killall -s 9 cgminer
 
/etc/init.d/cgminer restart

Hey everyone,
  I'm tearing apart the LUCI interface and am trying to figure out how to call the 'Save&Apply' button though the CLI.  I want to edit the crontab. Really wish it were just a php controller or something....

I rebooted through the web interface reboot option...when I power off via PSU Im suspecting that is when the multiple hour time difference happens and that is when the times are reversed...the miner status page shows minutes and the main miner uptime claims to be hours...haven't tested that aspect enough...for the record when I first turn the machines on the first thing I also do is go in and reboot them through the UI..have done this since S1 days...so many issues so many miners so little time  

you are correct they should drop price.   but the sp30 double miss on gh and on power makes the s-3  the best item to buy.

I would feel happy if it drops to .66 or .65 , but they may raise it more.


 With diff doing 2  under 10 % jumps maybe 3 under 10%   they could move price to .69 and I think it will sell.

I am looking to buy 2 more I want to see it drop to .64  I will not buy until my 2 come on fri and test well.

The best thermal pads are not as good as the worst grease....I can see why they said not to use pads as the heatsinks were machined with a certain tolerance to be in direct contact with the ASICs (I will find out how much now when I take 1 machine apart again) pads are garbage just use a good grease and you can be messy applying it like Bitmain a la birthday cake icing style but its better not to get it where its not needed...the inside should pretty much cover the metal part with grease for optimal heat transfer ...I am about to take off the sinks from 1 of the machines and reverse the blades to see if it makes a difference..this machine went from 420ish to 400 now after a reboot  

why dont you try thermal pads...

I unplugged an old miner and promptly plugged this new, potentially damaged one right in.

After going inside, I realized these were heavier then I wished to carry at that point in my life. So I set both boxes down, rubbing my back gently, as I can get some aches from time to time.

Staring thoughtlessly at my new miners, still wrapped in their plain brown boxes I remembered 3 things.

First, I really did not like the new waitress at the restaurant down the street, she was quite ugly.
Second, I was thirsty and wanted a beer.
Finally, I really had better get these things down stairs, before my wife arrived home.

Then what happened?

There is WAY too much BAD information in this thread...from overclocking to advice...WOW

STEP 1: VERY IMPORTANT!!!

Update the firmware IMMEDIATELY, and do not tick the box to save settings....you will have to wait a few minutes...lets say 3 minutes TO BE SAFE..DO NOT POWER CYCLE THE UNIT WHEN UPGRADING...then re-enter all your pool info...if this is too hard to do, then shut your machine off and call it a day...

I have done the front and back heatsinks....the front is not really what needs the proper surface contact as much as the back...hate to break the news but after reading through this thread I cant stop cringing...and don't know where to start...so here we go... since you only are concerned about the tiny little heatsinks which clearly are not as important as the MASSIVE ones in the middle of the unit    


DO NOT USE ARCTIC SILVER 5 IT IS CAPACITIVE..OR ANYTHING WITH SILVER IN IT.... STOP THIS NOW and if you have done this....get cleaning using a proper electronics alcohol FFS  

Not Electrically Conductive:
Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

some good grease to use is GC Extreme but a little thick for large application...GC Supreme works much better for that....

as for attachment of the semi-useless heatsink...do all 4 starting with the outside ones first then the inner 2, then tighten them 2 off kind of like when you change a car tire..if you don't know what I mean then I suggest learning how to change a tire properly for starters..bolts make all the difference but I digress  

As for clocking/stable running units...I am working on the how and why...so far I have seen every unit behave differently and hate to say it but the grease did not help the hashrate drop AT ALL

BITMAIN really needs to fix the firmware on these units...at least make a universal interface...this one is a hack of S1/S2 but missing all the basics like not having the page timeout, the option to have password saved in browser for starters
More important, there is a bug in firmware which shows inaccurate stats, for example when power cycle the unit, it shows uptime of 8 hours and the unit showing 1 minute, resulting in WRONG average hashrate for many hours

Quick question.   My Antminer on any clock setting seems to run at the expected hashrate for a few hours until eventually dropping off a few hours later.   The stock clock drops down to 410 gh/s after a little white and then the overclock speeds drop even further.   I do have 4 power connectors attached.   Any suggestions?

You guys had plenty of time to place an order before the bitcoin price tanked.  Seriously stop complaining and acting as if the sky is falling if they raise their prices.  If you are a serious miner, you already have your S3's, or ordered them already.  If you are a casual miner, you shouldn't care about .01-.1 price fluctuations.

I'm getting really tired of people coming in this thread and flaming the only reliable mining company in the business that constantly gets better and better.  Seriously.  Stop it.

I just read the announcement. WOW.
They basically said:

We're going to bend you over, it might hurt but we're going to use lube, even though our T&Cs don't say we have to use lube. No we don't NEED to use lube, we're lubing up as a gesture of goodwill.

A gesture you should be grateful for. People have been crying out for lube, we talked to some guy that didn't lube and we knew we couldn't get away with that, so we decided to throw some in.

Yes you have to pay extra for it.

Oh you don't want to?

Well then you're just going to get F**ked

Have you taken the unit apart and checked your thermal paste?

Yes "warranty' have not much value in the mining hardware.
41 - 42 was my temperature peaks at stock clocks.
I don't have any link to the thermal grease for now.
I'm searching for it to buy the same brand or the alternative one having >3 conductivity.
But most of the products I'm seeing is of conductivity 1.
I will post here the link if I find it or some else who has experience in doing this will support here.

I put a ticket with bitmaintech support and I wish to share it with you all.
My S3 was hashing low at 400 - 420. Long term average was 421.
Bitmaintech engineer told me to remove the heat sink, clean it with a cloth and apply thermal new paste.
They recommended to buy "Dow Coining thermal paste grease" for this purpose.
Which can be sourced from ebay or amazon.
If its not available at your location buy any good thermal grease which has conductivity above 3.
Also I asked then about warranty issues if that type of a hack ws done, and they assured me that no warranty will be void for doing it.
