Pair of s-9s now running photos are up.

[philipma1957]

Be patient just got back from solar array with setup.  2 units running. had to downclock just a bit.


photos to come.

Looking forward to your review! 

[sidehack]

The one to be delivered here today looks like it was picked up late and sat for a while, so it probably won't arrive until Thursday. Tomorrow possible. Darn, and I was hoping to be the first one to post pictures.

[philipma1957]

we needed to get lower freq

but here are final setting on the 2 running

freq 625
fans at manual 70%

I'll leave other to post pics. Got mine today and so far am - happy - with it but...
A. is so far averaging just over 13THs
B. A thermal design issue raises it head with these. The middle card and the one with long finned heatsinks facing the case wall run well over 4.3-.5 THs each. They report chip temps of around 90C. The one with the short fin topsinks facing the case is giving a bit over 3THs and reports the chip temp as banging around 99-100C. The air coming out of that card is also substantially warmer than the other 2. Will measure temps tomorrow sometime.

The root problem is that the short sinks are presenting a much high airflow resistance because the flow channel is restricted by them and the case wall. If somehow move the cards over a smig, hell even 1/8" might do it, then airflow should remarkably improve.

edit: Also, mine wants to be a howler but I found a way to mitigate/highly reduce the siren effect: Put a square piece of open cell foam (air filter kind) over the grill of the intake fan. Suction will hold it fine but a touch of glue/tape whatever wouldn't hurt. Anywho -- it disrupts the airflow just enough that volia' howling gone.

Of course your mileage may vary

yes short term I down clocked from 650 to 625.

But UPS was late.
I had to dissemble the avalon6s from the array.
My sprained ankle from 65 days ago still hurts. ( bitch to be 59 it would have healed in under 10 days when I was 25-30)
The mining gear is in a loft with a ladder.

First time I turned them on I climbed down the ladder knowing they were mining for bitmaintech. So we went to the pc to check them and  setup kano.is

temps were very high   chips in the 90's






only 2 machines and a large loft  I was supposed to point miners in the direction in this photo
about 70 feet and an up draft fan in the center

[NotFuzzyWarm]

Hmm, wonder if I could fit an English Wheel (metal panel forming tool) through the case to bow out the top-sink side? think think think...

Thanks for the effort and picts, phil.
kano.is IS....

[philipma1957]

so once I realized miners were blowing hot air at the near wall I spun them around  this allows for okay temps

here they are blowing air  towards the far wall  about 70 ft


here are the avalon6's  I replaced.  you can see the grates below allow cool air to be pulled from below.

pointing the s-9 units towards the far side did get temps okay.

I guess with these high temps we can assume that the fans are as loud or even louder than the S7s

[philipma1957]

loud as the s-7  and I have one unit that squeals like a stuck pig.

I know there is a fix for that if anyone had a squealing s-7 and wants to post the fix please do so.



My guess is we will mine at 600 to 625 with the s-9's until the fall  but no pressure at the moment to decide.

maybe simple box fans will cure all cooling as we only have 2 units with two on the way.

They'll probably run even hotter at the default clockrate. I wouldn't be surprised to see miners breaking down in the summer heat. With these temps, you'd either have to underclock or replace the fans altogether- those temps will shorten the running time dramatically. Disappointed that Bitmain shipped a miner clocked so high that it can't even manage it's default clock speed without high temps. Just more proof that their quality is going downhill fast...

Lol sorry, ninja edited 3 times. Perfectionist :c

at what I paid for these  no oc until sept or oct.  I need to get back some money.

oh I am pretty sure these pull more juice then the s-7 when set to stock.

re-read my post https://bitcointalk.org/index.php?topic=1512186.msg15212835#msg15212835 for the edit about that... The effectiveness varies with fan speed but helped immensely here. Should apply to s7's as well.

[Swimmer63]

I'm confused.  Now they are giving us two temp readings.  In the past, for the S7 and others have we just been seeing the pcb temp (labeled: Temp).
Then why now they showing us the chip temp.  Why is that important now?  Poor design?
My pcb temps are running 56, 56, 59 at 625M.  On any other Antminer I would say there is plenty of room for some over-clocking.  Or in this case to move to the default 650M. (EDIT)
Chip temps are 87, 86, 91.  Are these temps higher than an S7 with the above pcb temps?  In other words is there more of variance on this miner than the older ones.  Where we can burn out a chip before the pcb gets to 80C.  That's still the safety shutdown temp. I believe.
Inquiring minds want to know.

I had an S7 that the fan squealed.  The trick was to move a small piece of paper around the intake fan.  You keep moving it around until the you find the spot that the squeal stops and then you tape it there.  Another solution that worked for a bit was to loosen the screw a little bit.

Do you know what the ambient temps were when you got the screen grabs?

thank you  I will pick some up at lowes

I'd go with the 1/4" thick stuff  which is what I used.

I would think  it was 88f  because it is a loft.

I am not sure the safe chip 0c number ,

I know that

 spondoolies sp20 chips throttle at 125c

intel cpus' throttle at a 72c junction point could be wrong on this

amd gpu's throttle around 93c


but  the readings may not mean much.

the pcb number of 65c should be good
i do not like to see a chip number near 100c
i was near that at 97 c

but the fans are now pointing at the far wall not the close wall
the fans are set at 70% = 4300 rpm
freq dropped to 625 vs stock 650.

here is a screen shot of the two at kanos pool live time 10:10 pm

at freq 625 we are getting 26.82-27.33 th
two units = 4300 usd better safe then sorry

Damn that's sweet stuff.  Always fun reading up on the solar array you have going
