This means I got fucked by chinese customs as well??  Should I expect 1 WEEK delay now?

how long did you check this for (2 instead of 4 connectors)?

you removed the inner heat sinks ?? how much time and effort did this take ??

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    

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

Actually, I did, in opposite to your "theoretical" rhetoric.
Cleaned the BMT blob, applied a thin layer of AS5, everything is fine, but speeds did not change at 18hr post-application, temperatures dropped 1-2oC
I am a patient man, but your are exceeding my limits. It is a first indication of a weaker mind to engage in name calling.
You are free to use whatever, I used AS5 and it is fine. Probably would not be fine if I put a pile of it there.

unfortunately you are confusing electrically conductive and capacitive conductive with thermal conductive ..
AS5 is not electrically conductive but it is capacitive conductive ..
if u use AS5 you could potentially still see problems if it touches asic pins or other electronics.
gc-extreme is neither electrically conductive nor capacitive conductive but still same thermal conductivity as AS5.
not sure why we wasting silver in a thermal paste anyways...

No, it does NOT. Please stop posting potentially wrong info with so much emphasis.
From the product sheet:
Not Electrically Conductive:
Arctic Silver 5 was formulated to conduct heat, not electricity.

Sheesh

regarding thermal grease: unfortunately reapplication of grease did not help AT ALL (at 18 hr mark). See below how bad the grease was applied in batch 3 machine by BMT, yet no help from new grease. This also shows that if you put a blob on, it stays pretty much a blob and does not spread (this probably depends on its viscosity, though).

As for the blob..all it shows is that the heatsink was poorly machined and/or applied improperly IMO

Since you like your AS5 so much why don't you take the inner heatsinks off and slather that on see how far your get....see the big shiny....ohhh I said too much

Exactly. You said that it conducts electricity in your barrage, NOT that it has capacitive properties. Keep it away from pins and you'll be OK. Conductor=material that permits passage of electrical current. capacitor=electrical component used to store energy ELECTROSTATICALLY.

You are both a danger and a joke at the expense of your own EGO? why not post the rest of the page FROM THE AS5 SITE?

You won't need the double quote now since you're just goig to change --queue 4096 with quue 1. What iu are doing is replacing this part at the end of the command:

--queue 4096

with

--queue 1

To see the line you want to change in the file out can just run a grep to see it:

grep "queue" /etc/init.d/cgminer

The output will show you the line out will modify with the used command. It will also show you that queue only shows up on that line.

So, to be clear this is what you want to enter if you are editing the file from default. Including backing up the original file:


Go to the web interface for the miner config and click save and apply. This will restart cgminer and it will reload the new config.

Not a software coder, got it here, but please correct if it is so.

Just a heads up, we sell single units - scope my sig 

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?
