So I can kind of tell where the wires go from that image, I don't think I'd feel comfortable going by that alone, though

I agree, I would love it if SMILY could describe in more detail how the wire should be connected.

Hey slightly off topic.

Had a batch#3 running at 350 fine for a few days (110ghs). - Then the power went out. and since then It will run fine for maybe an hour before going down to 10-15ghs.

I've tried it at default settings (300) and it does the same thing. - Temps seem ok (under 75c) - Is there a reason for this? :S

 disconnect the ATX Motherboard Power connector after you turn your PSU switch OFF.   Reconnect your ATX PSU connector to the controller board.  Switch the power on.
Also make sure you have all 5 power cables hooked up.


2 x pciE 8 pin

2 x CPU 8 pin

1 x atx mainboard power connector.


Make sure your avalon options is set to:--avalon-auto


Only other thing I can think of is you may have to reset cgminer and apply settings.

Before you reboot the machine, first have a look at the tab

Status -> Cgminer API log

and look at the numbers behind

Code:

   [match_work_count1] => 239017
   [match_work_count2] => 239336
   [match_work_count3] => 240190
   [match_work_count4] => 239549
   [match_work_count5] => 239449
   [match_work_count6] => 239708
   [match_work_count7] => 238995
   [match_work_count8] => 238508
   [match_work_count9] => 239126
   [match_work_count10] => 239069
   [match_work_count11] => 238590

chances are one of your modules is not getting power and it will show it with considerably lower numbers (might even be 0)

The modules are grouped by 8 lines so you can spot where the problem is

My miner restarts every 3-12 hours. 

Status   MHS5s   MinerCount   AsicCount   Frequency   Fan1     Fan2   Fan3    Temp1   Temp2   Temp3   NMW   Firmware
Alive    106523.25             32              10           355                2640    0        2640       28            70          66         112          20130723




My assumption is that it affects my overall bitcoin count on slush's pool.

Now is this a good thing or bad thing?


How do I stabilize the restarts?

How do I stabilize the restarts?

Try firmware 20130821, very stable and I picked up ~2GHS over the stock 20130723.    

edit: Oh, and mx4 thermal paste on 2 modules probably helped a lot. I thought a 20g tube would cover 3 but I ran out after 2.

So my hashrate just dropped to 40ghs and this is what the log is showing.

Everything looks fine?

That looks normal

Which hash rate are you talking about, the numbers reported by the pool or the MHSav number under the Status -> Cgminer Status tab in the interface?

I sometimes see the pool reporting lower numbers than the web interface



which is something I can't explain (power consumption is also the same)

My current solution is to hard reboot the machine when I spot this

Can you make a screenshot of the Status -> Cgminer Status page?

Where can I download the latest firmware?

Cheers 

Here you go:  http://ck.kolivas.org/apps/cgminer/avalon/

The cgminer thread:  https://bitcointalk.org/index.php?topic=28402.0

If you are using a July or earlier rev I think you will notice a nice improvement.

HELP!! I flashed the bios to 20130821 last night and now its 20x worse!! Runs at 100ghs for about 30 seconds before dropping to 5ghs - 20ghs erratically. Left it for a few hours and no better. Tried a couple of versions in between with same results before flashing back to original backup and now that's fucked too

Any suggestions? this is killing me!!!

Yours is a batch #3, it's probably throttling because of temps as the sensors have changed so the default temps are too low

In more options try
--real-quiet --avalon-auto --avalon-fan 100 --avalon-temp 70 --avalon-cutoff 90

By the way I would still not generally recommend setting the fan above 80% due to the design flaw that makes the higher pressure 38mm fans blow so hard that the low pressure fan 25mm is spinning but air is moving backwards through it.

My pleasure.

Does that apply on the batch #3 too ? Not had the case off mine but it appears from the outside to only have those 2 high pressure fans, changed it anyway.

I don't know to be honest. Is there no 25mm thick fan in the batch 3s? If not then it doesn't matter. Generally I'd suggest leaving the fan on the auto settings since I spent a lot of time making them work for optimal temperature/fanspeed/energy consumption.

I have a 4 module running at default settings with 300 frequency. The temperatures are 15 42 34. Should I up the frequency with stock psu? It's running at average 95 ghs. Thanks for any suggestions.

[HerbJones]

Hi All,

So thanks to all the help with everyone on this board. Here is my setup:

[Firmware Version] => 20131229
Chip Frequency(Default: Advance):  350.
More Options(Default: --quiet):--avalon-auto
HashRate:   ~110 GH/s is average;
Uptime:   24 hours - going strong.

Cheers,
