Maybe a silly question, but does anybody know which fan (front or rear) is supposed to be on the board outside connector?
I cleaned all my miners, and they are different assembled.I know the fans are different, so it should be specific one on front and one for backside fan.

Anyone?

It doesnt matter which one is front/rear, as long you put the correct air flow position (the air one in and one out).

Interesting.... Thank you! guess I'll have to buy one ..


Never buy 1.......always buy at least 10

haha, you see, I have special hardware that identifies broken chip in the chain. I need to check if it works with S9(i) version.
It communicates via serial interface through the 18-port wire that runs from controller board, but I am not sure if different voltage will make my device unusable... hope it won't...

I have that too, pretty damn expensive

AND the numbers are IN!


S9i 14th at the wall (230v) = 1430-1445W

same test setup

A841 13.5th = 1280-1320W

Sorry Bitmain, Close......but not close enough

U sure this is correct? That is 7% more power for about 4% more hashrate?

Selling 100 dollar coupons (8units expire 11th June, 14 units expire 1st july) and 125 dollar coupon (2 unit exp 30th June). Selling at 20% of value

1. How much did you pay for it? (if you don't mind Wink )
2. Have you checked it on S9(i)? I just bought one to be delivered in June, have to check if it works or not...
I really would not like to buy miners that I cannot fully test/repair myself... I think you have similar thoughts.

So say you've identified a faulty chip. Can you locate it physically, and then do you just replace that chip with any other chip from a replacement board or they are all individually assigned for each slot?

No assignment my dude, which made me very happy.
Just replace with the fresh one, or with the one unsoldered from another board.
But you know sometimes you also have to check voltage values of the other board components, because sometimes other components break too.

Ah thanks. How much is this hardware and where can you buy it from? ANd do you get the boards of ebay or another source?

Also you need a rework station to unsolder and resolder chips onto the s9. Machines can be gotten for under 5k used.

massive dump of gear .  750 -100 coupon = 650 for an s9 add back ship 750 a unit.

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Time for the S11+mini!!

maybe .

I really hope they go lower watts with it.

I have space I do not have a ton of cheap power available

I would like to use a piece of gear that does 800 watts and mines 12000 th

that would be 0.0667 watts a gh

most likely it will use 1300 watts and do 18th which is  0.0722 watts a gh.

the t1 does 14.2 th at 1300 watts which is 0.0915 watts

It has been a long time since I manually setup any miner.
Does S9 allow direct access through ethernet cable and 192.168.1.99 IP address like S1 and S3 did?
If yes, then it does not work for me.
Accidentally, which setting do you put for laptop IP and router IP in case if it should work still?
I put
192.168.1.1 for laptop and
192.168.0.1 for router (or should it be 192.168.1.0 for router?)

I have a particular reason to try this, I am well aware that if you connect S9 to the internet, it would situate itself just fine on DHCP.

Thanks.

The s9 default is using DHCP so you will need to look at the router for the address. Once in you can then set it to a static address. Routers generally use either the first address (.1) or the last one .254, at home mine is .254 while at work it is .1

Ideally both the router and laptop should be on the same subnet.

If you connect the miner directly to your laptop, set your laptop to an IP in the range of 169.254.0.0 to 169.254.255.255, subnet mask 255.255.0.0. Without DHCP server both the miner and the laptop will auto acquire an IP in that range.

Not sure why the "moderator" is deleting messages though it is related to the subject. It is a forum after all and people provide opinion and help each other. There are like 8 messages missing when I have checked today.

What was of topic with this message:

Sorry I know this has been discussed many times on here but I can't find it on this thread, but just have 3 questions.

1. At what temperatures should my S9's be constantly steady at? Does this look right at all?
2. Is it possible these asics can last more than a 2 year lifespan with great maintenance?
3. Should I change my Estimated Payout period from 0.01 to 0.1 due to pool fees at pool




1- I try to keep mine below 80. Averaging 75. But no matter how low I go with the cooling (mine are in 20 deg), the fans are not going below 3700is rpm.
2- 50/50 but it is possible. I have a T9 running since the 1st release, running non stop with the same PSU. Keep away from dust and humidity. Open the miner every now and then and clean the dust.
3- it is up to you. but the higher the payment are, the lower you pay fees.

All my messages from the previous several days have been deleted...

Same here. Hmmm unfortunate. It had good info and it was about mining. I read an analyst report and it suggested 30-40% prepaid wafers by bitmain had been deployed. This is on in may.

So, I guess they still have to dump machines due to too much prepaid wafers, probably ordered in error during the times when the S9s sold out in 2 mins when released lol. Hopefully it gets cleared soon and no more wafer over-orders occur. The Z9 now becomes a 2 for 1 lol. They wanna clear the wafers that bad.

Maybe now 60-70% of wafers have been cleared?

Selling 100 dollar coupons (8units expire 11th June, 14 units expire 1st july) and 125 dollar coupon (2 unit exp 30th June). Selling at 20% of value

In one of my installation, board temperatures are in the range of 82-89 C. Ambient temperature is about 36-40 C, real hot due to summer at the moment. They run fine, occasionally hitting the upper limit and idle.

S9 will not profit soon ?

S9 would not profit if your daily operating cost is above USD0.13/kWh, just enough to cover operating cost / break-even to cover electricity/cooling etc.

See example below :-

(TH/s) / Opex (USD/kWH) / Profit (USD/D)
13.5 / 0.10 / 1.43
13.5 / 0.11 / 1.04
13.5 / 0.12 / 0.66
13.5 / 0.13 / 0.27
13.5 / 0.14 / -0.11

* Assumptions : Current yield of USD0.39/(TH/s), power of 1580 Watt/S9.
