Thanks. hm, thats big!

the plated area is 15cm wide and 14cm tall, hope that helps. let me know if you need other measurements!

yes no problem, can you wait a few hrs? im currently at the office but i will swing by home as soon as i get off (im in asia, its 446pm here.)

one board is 10x375Mhz. 3.75GH, is it worth it?

The exhaust fan grill, i would like to know its dimension! could you measure it for me? i will connect a aluminium hose to direct hot air outside, mine are overheating..

ok let me try, thanks man! is there a way to repair that particular part tho? or too hard?
whats exhaust pipe?

Same thing happened to one of mine. I just removed that connector at the top of that section of the card so it wouldn't get power when I put it all back together and its working great again now. Lost about 10GH I believe but at least its running again.

Just unscrew the top heatsink covering the two modules.
Unplug your broken module. it will start running again with 10 less chips unless something else burned.

Could you measure the exhaust pipe for me please?

where do i enable avalon auto? im running 0821 firmware. avalon auto will automate my hashrate/mhz for the safest balance?

also, i took my avalon mini apart in hopes of locating where the problem was. i was able to locate a black/seared area on one of my modules. im not really familiar with hardware and electrical engineering. so here i post a couple of photos so you guys can help give me advice.

view from the top, inside the red circle is the place where it looks a bit burnt, that little rectangular box has burnt marks underneath it and the box is a bit loose. its still attached to the board but at an angle, the rest of the boxes on the board are firmly attached so it suggests this box may have popped?



here is the side view for a better look, whats this component? what does it mean when these things burn up? can i replace it and get this module running again?



any help is greatly appreciated!

thanks.

Thanks odi. i will look into it.

Question to to any kind soul out there, dimension of the hole blowing OUT air from the avalon Mini? i can only reach them after stores are closed.. :/ The aluminium hose has 8cm, 10cm or 12cm where i can get them.. i think its 10 or 12cm.

For a batch 3 avalon, I used the following parts:

http://www.homedepot.com/p/Master-Flow-14-in-x-6-in-to-8-in-Universal-Register-Box-with-Flange-RBF14X6X8/100154377

Obviously, find a register box that would fit your needs.  This 14x6 barely fit the batch 3 after I straightened out the flanges (tear apart welds and unfold) to act as an air funnel that the avalon sits in.

Choose the correct size booster to fit the other side of the register.  I connected the register box directly to the booster, and used duct tape to seal it.  I didn't seal the register box to the avalon, so I figured a booster would help the exhaust go the right way, instead of out the unsealed part.

Choose the correct size duct to match the booster.  I simply used duct tape and some bungee cords to exhaust the hot air outside.  I chose this instead of the insulated kind because it would be easier to work with (insulation needs respirators and special washing of clothing after).

These are the parts I used because they were all available in B&M stores, as opposed to having to order online and wait.  I had just gotten my avalon 1.5 days before and the uninsulated room I had put it in was already 10F warmer than outside and still rising.  After this, the room is at most 2F hotter than outside.  I debated using it as intake, but I worried about taking outside air directly without a filter / water drain.  As an exhaust, the walls act as a big filter.

 FWIW, I tried driving my Redhash unit over USB/Zadig with CGMiner, and it produced an undesirable amount of duplicate shares compared to running off the TP-Link's firmware. Not sure what I was doing wrong

yes CK firmware i only use --quiet

what does the temp say?

And your using the CK firmware? The 1.5% HW seems a bit high for 400Mhz, I get 0.8% on my Mini at 400Mhz.

 zerocode: Did you get your machines working through direct USB ?. Can you please post a reply with details of the process ?. Did you use Zadig to install WinUSB ?(was it the latest version).

Thanks, this has been working great for me. Its been keeping me ~1% HW and 65-70gh/s. I have the unit half out my window here in NorCal keeping it nice and cool. I think the auto restarts are helping keep the machine stable. Thanks again.

in an uninsulated attic with wide open for 2 mini  and 2 -4 modules -- all 4 in wifi

and same setup in another an uninsulated attic with wide open -- all 4 with ethernet cable

all front window in the airstream

the temperature depends attics outdoor temperature

i can do a picture if you want and check temperature.

the better mini i have i set at 404mhz with 1.5% hw and rarely restard alone or by me. 2 other at 403mhz with 1.5% hw and one at 398mhz and 1.5hw

i prefer my mini 2 modules instead 4 modules for sure. better performance for sure and more stable. rarely restart alone.

i not use --avalon auto

Yes you need a cold environment to pull off 400Mhz and above, so why not get yourself one of those big freezers that DQ uses and stick your Avalon's in there? They deep freeze ice cream without its becoming stale, if you live in warm/hot place.

very very cool enviroment? you are not on --avalon-auto?
i'd say its stretching it unless its very cool..

found module dead and unplug it and you can run again with only one module

my 4 mini work fine at 400 and little more 403mhz. only one at 398 because at 400 alot of hw.
