your utility is very low!
assuming that you are in a stratum pool try to set variable difficulty at 64 to 66, i am not sure about the exact number though :p

Where do I set that?

it's usually in the registration of your worker at the pool you use that you can set the initial value, but as far as I understand the pool will adjust according to your work results. So it should only have an impact on the first activities

By the way, these are the numbers I'm getting from btcguild:


Code:
[SUMMARY] =>
(
   [0] => SUMMARY
   [Elapsed] => 69956
   [MHS av] => 71381.83
   [Found Blocks] => 0
   [Getworks] => 2573
   [Accepted] => 36271
   [Rejected] => 150
   [Hardware Errors] => 815
   [Utility] => 31.11
   [Discarded] => 4786
   [Stale] => 0
   [Get Failures] => 0
   [Local Work] => 1223915
   [Remote Failures] => 0
   [Network Blocks] => 144
   [Total MH] => 4993602159.0807
   [Work Utility] => 1001.57
   [Difficulty Accepted] => 1160672.00000000
   [Difficulty Rejected] => 4800.00000000
   [Difficulty Stale] => 0.00000000
   [Best Share] => 1430374

Anyone have such high HW errors? What does this indicate?

Hi luffy
how big should it be (Utility)?
I have also about 30.5. (vardiff 32)
Edit: With vardiff 64 i get 15.5 Utility

PSU cold air intake is a little bit insufficient, I'm planning to add a fan out side of PSU exhaust to help cool the PSU. Currently at -1c degree there is no problem, but when summer arrives, ambient temperature could reach 25+, it will become an issue

Summer ambient for me can reach 43°C.

I'm in the US. Will one of these work on my 15-20amp circuit? I have all 110V lines of course, regular house. Do I need to install a 240 or something?



It only uses 600 watts. Should be fine on any 110 outlet unless you have a coffee maker and a microwave on it too.

How loud are these things? Also looks like if you have 20amp circuits you can only have 3 units per circuit  assuming you don't have a ton of other stuff already plugged in! Then maybe just 2. So much power use...

I did when I was overclocking with --avalon-options 115200:24:10:45:300

Changing to --avalon-options 115200:24:10:42:300 cleared it up for me (thanks to luffy for suggesting it).

Supposedly the fourth parameter is a "controller timeout".  I'm not sure why reducing it helps.

I tried different parameters, including the default 45/282 value, the result is almost the same, hardware error rate about 3% of accepted, and my ambient temp is -3 degree now
   [fan1] => 0
   [fan2] => 720
   [fan3] => 720
   [temp1] => -3
   [temp2] => -1
   [temp3] => 28
   [temp_max] => 28

Probably.  I imagine the restart will be the easy part.  Detecting the failure condition programmatically will be the harder part.
Of course not ... my API has all sorts of information that will show the condition ... and if the API isn't working, you take that to mean the condition exists also.
Of course there are updates to the API but ...

Cool.  I'm not too familiar with it.  Is it JSONRPC just like bitcoind?  Care to give a cookbook query string to get the current hashrate?

Someone asked if i moved all modules, or just one - the answer is
MOVE ALL THE MODULES Grin

I encountered the fan/temp bug again this morning.  I noticed it cycled the fans on maximum speed for about 200ms, and when I checked the cgminer status page again the temp and fanspeed readings showed non-sane values that varied rapidly and were sometimes negative.

It also stopped hashing.  I presume as a safety measure.

I let it go like this for about 3 minutes this time to see if it would recover.  It cycled the fans onto maximum for 200ms a few more times, but never did.

When I restarted cgminer via System --> Startup in the web UI, it then mined normally again and showed normal sensor values.

is there a way to automate the cgminer restart?

So i moved the modules, and it seems to be better at first look.
WARNING: use your own mind when considering doing the same.

I really smiled when i seen this picture, this is a strange solution.
I'm sure ngzhang will post that he puked when he saw that picture :-)
