PowerSupply: OEM
Extra CoolingSetup: None - Outside in NorCal Ambient 34F to 62F
[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,

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.

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.

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.

Wow thank you so much. that appears to have been the problem Cheesy

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

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 Sad

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

Where can I download the latest firmware?

Cheers Grin

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

The cgminer thread: https://bitcointalksearch.org/topic/official-cgminer-mining-software-thread-for-linuxwinosxmipsarmr-pi-4110-28402

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

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

Quote

[match_work_count1] => 23548

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?

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.

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

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.

Where can I download the latest firmware?

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?

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

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.

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 Tongue

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

I have a batch #2 unit, currently set at 350 mhz and giving 82 gigahashes.

Is it possible to make it run even faster, just by managing the temperature, but without modifying the hardware?

What I mean is - can I manage to make it work on 400 mhz, just by cooling the room where it's standing?

You could at least try the wire mod for voltage stability across miner boards ... this may yeild some increase in mhz and maintain lower HW error rate. But, probably not to 400mhz.
I would gather somewhere between 365-375mhz...maybe? Past that ya need to do resistor voltage mod.

Is there a high-res photo or more detailed instructions on where to connect the wiring to stabilize voltage?

I think SMILY plans on making a complete writeup soon as well for his mods.
