I believe this one will have the leads you need to attach it to the board

The other one is a surface mount device and would be harder to attach.

Mtnminer

so after replacing almost two dozen screws with longer ones its starting to come together.

only issue now is the capacitor? marked A 997 330 16v popped off near the ribbon cable and the legs broke off.

Where can i get a replacement?  i tried searching mouser.com but i dont know what i am looking at.

is this it?

how do i solder it on?  do i heat from underneath?

Can I run this with the missing capacitor?

(bought on the 10th. They said 11th. Received today)

So (and I hate sounding like such a newbie), what now?

Is their a post that someone walks though it, or do I follow the regular avalon user guide at: https://en.bitcoin.it/wiki/Avalon#User_Guide ?

From what I can tell, either should work.  There is actually enough room to solder each leg from the top (the plastic guard underneath might get an edge melted, but that's no big deal).  I soldered the one that fell of my board back on no problem (slight edge melting of plastic underneath).

i think my legs were too short to begin with so i failed miserable.  also thanks for the temp sensor.  we should create a google doc that we can all add tips/tricks and links to stuff we need for this thing

where is the temp sensor supposed to be mounted?

This was asked earlier in the thread, though I know it's gotten long now.  Anyway, it should be between the fins of one of the blades, preferably in the middle and jammed back in pretty well.  I put mine somewhat more close to the exhaust side of the upper blade, but it probably doesn't make a ton of difference as long as it's in the blades somewhere you think will give a good gauge of the temps they're seeing.

Can someone check the main board. I have this three wire thing plugged into P3. And it's like 30 inches long and capped at the end. What the hell is it?

Pics? Could it be the temperature sensor?

EDIT: Oh wait, I just looked at my main/fpga board. P3 is the LED.

EDIT2: Nope, sorry, P3 is actually the temperature sensor on my board. Forgive my temporary stupidity. P1 is the LED.

Funny story - if I heat up my temperature sensor the fans actually slow down.

"--avalon-fan 50" did it for me, locking RPM to ~2000

will run it underclocked to 1000 Mhz at night

i hope it wont catch fire this way and my neighbors get their sleep

My fans only wants to work when i remove the sensor, is there a way to fix that ? I think its not the sensor as temps are showing when its plugged. Im not good enough to figure out where it comes from...

Anyway, im finally hashing since 24hrs !

heatsinks are 20-22°C

chips on push-fan side are cooler (~40°)
maybe some have not good conduction?

Try --avalon-fan 20 to cgminer options, last field in config it should lock the fans to 2200 which is not bad. See if it overheats.
chips on blow-out side of the board already have 90°C (IR thermometer)

should i still risk to calm the fans?

Chips are always hot they dont die in 90c
Hard to say without being there. I would try it if noise bothers... still it might overheat. Touching the heatsinks will give some feeling how it cools. If you can touch the heatsinks without burning your fingers your good to go. My ambient temps are low in warehouse but this is what i get with OC.

If you cant hold your fingers at the heatsink it's too hot.

7hours solid. But my fans are not locked to 2200 in this unit and it's OC 1500... it's in warehouse 16c atm. Try it, it wont fry if you watch the temps.

So, i finally got it.  Lips sealed pix -> http://imgur.com/a/CZqFE

and yeah that termal sensor is strange, a ntc one, fans runs faster the colder it becomes
still no clue where it should be put for optimal temp/speed control

Lucky you... got somewhat ok unit. Try --avalon-fan 20 to cgminer options, last field in config it should lock the fans to 2200 which is not bad. See if it overheats. With that 205GH/s you propably got all chips hashing ok you can chek this in the api-log tab after 30-60minutes of steady hashing the number should be eaven with all workers.

--avalon-fan 80
is enough to cool this unit in most normal room temperatures at stock speed of hashing.

HW errors should be around 3-4%. It is DH% value in status page.

Happy mining.

my brother missed the postman, but my dear drove me to their pickup point to get it today.

the unboxing came with prooven bad expectations:
some loose screws in the box
no double-plug but two standard cables, and the wrong ones (ordered eu, got asia plugs)
one of them bent so hard it can only be scraped for wires

opened the case:
led was loose
some wires dangerously near, almost touching to the chips
and the annoyingst thing ... network jack was jammed, but managed to hammer the cable in

but at least: no wedged-in heatsinks or seriously broken stuff

it runs 204 G on average while louder than a BFL - 60dB near it and still 50db at the end of the floor
i can hear it through a fucking metal firedoor!  Shocked http://youtu.be/-L3U_bFtGkU

Has any one here in the United States received on of the miners delivered by DHL on a Saturday?  I am hoping some one can say yes   Huh

Thanks in advance for the answers
