Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[gt_addict]

Quick question. Whats the average fan speed the S9 does to stay at the temp it needs (I know its ambient temperature dependant)? Also whats the max RPM the fans do?

4300rpm fan and a 6000rpm fan.
This question is highly S9 model and ambient temperature etc. dependant. Try to find the sweet spot in your conditions.

Thanks HagssFIN. Just trying to work out whether (when I have enough BTC) to buy an S9 or an R4. As its the noise that would drive me crazy. My S7LN fan speed never gets above 1800rpm in an abient of 19-20degreesC. I know the heatsinks are larger so cool more effectively but the S9 or R4 would only be clocked to run at 4TH anyway so im hoping I could get the fan speed down to 1800-2000rom on the S9. Does that sound feasible?

Sounds possible depending on your conditions of course.
In that situation you should have about 400-500W of heat to dissipate.
The problem is that I don't know if that kind of a underclock is possible with the new S9 models.

where all account info has gone from bitmain?
when i log in (successfully), there is an empty space.
there is an icon, when I click on it it say account, click on account, it says  information and security settings and NOTHING ELSE.
weird (ALL prior orders are not showing)

does anybody else have the same situation?

Got it, it is organized in an awkward way: you account info only visible when you actually place an order, NOT when you login to bitmain.
makes some sense

In firefox: when click on coupons, there is a blank page that says coupons on the top with number 1 on the bottom, nothing to choose.
I guess I don't have any or it is wrong page layout.

That's why I would spend a little more on an older 11.85th S9 from that Eastshore place and if I find the underclock wouldn't work across three boards I would run just two boards at a freq that would suit.

On a side note, thanks for sharing your experience with the eatshore company, as ive said before its the customs fee that would kill it for me so finding that place (although slightly more than buying direct from bitmain will save me money on customs.

Np. Yeah my second third S9 is on the way from Eastshore, in international shipment release in Shanghai at the moment (carrier: Fedex).

The R4 has been sold out since they first launched it. They haven't released any subsequent batches yet, only S9's have had more released

Have they really only released one batch? and my bad sorry

Yea, just the one. I emailed a little while ago asking if they had more in the pipeline but got a vague message saying that they were in demand and some other stuff which didn't really relate to the question I asked. But anyway that's a discussion for the R4 thread .

do they ever post changelogs showing what was added or removed from the firmware?? its like they post daily updates but no one knows what exactly is included in that update.

[Biffa]

Both my batch 18's look like they might have a dead board in them after just 8 days use.   

Need to check when I get home

Nope.  Hopefully we hear some opinions from end users.

temp on batch 19 after upgrading to latest firmware


PCB temp between 70-90C

What pool?

so cooler then? Faster fans?

[sidehack]

Looks like it's by no means stable. Thermal cycling is hard on the works.

agreed. Looks like around a 20C swing for them. Mechanically that is not good for the chips and more specifically their solder bonds to the boards.

I just looked at my s9's and even the B17 and my latest a B18 (both never upgraded, has the auto-tune) is holding temps to about a 8-10C swing. I do see that the pre-auto tune ones with manual fan control have less variance, seems to be around 5-7C with my fans set to 85%.

In your screen shot I take it the gray-dotted trace and a couple others (~10C swing or less) are non-autotune miners?

[HagssFIN]

The autotune batches seem to be a total flop.

[wolfen]

Anyone try the old firmware on the new autotune s9?
I have 3 autotune s9's.
One is running 644 644 590 freqs on the gui.
fans show 4500/0 awesome, gui shows 2300/2300
Awesome miner shows 706 706 706. What do you suppose that means? Awesome miner not  quite working with autotune s9's?
