Here's stats after 12h of mining my S9. Hashrate far below 14TH. At 650MHz hashrate was below 12TH and definitely ailing last board. Best hashrate got at 606.25MHz, 12,5Th @ 1310W from wall.

what is the ambient temperature in the room? I suspect that getting 14.0 th will not happen unless room is 70 f or 21.c

and that board is not sick 61c and 93c are fine

Did you use multiple accounts to buy 11? Did you buy more than 11?

Also, does anyone have a link to the spec sheet on the BM1387? I can't find it on the site but I suspect it's there somewhere.

Yes. I used a few more friend's account. Miners from my own account I received yesterday. The rest should be today.
I bought yet only 2 pieces more
1 x Batch2
1 x Batch3

Mine for a Bit

Quote from: Cassey on June 16, 2016, 09:11:09 PM

Almost at 2 hours now, web page indicateds 13,544.19 GH/S(RT) and 13,6954.32(avg) - just added the "Lowes sound mod" and noticing the temps go up a few degrees - now at 65-67C.

Of interest, Slushpool is crediting my S9 with 14.53TH/s over the past hour:

My units are in a basement "machine room", so thinking of removing the grills to see if that helps. On my S7s, I found partially blocking the intake worked, but raised temps. Using a block of 2x3 lumber BEHIND the unit brought the sound under control. May play a bit more before disabling the safety grills.

Buddy, Slush's has the BEST dashboard, but CKPool has the BEST profits.

Right - for this and fee reasons never use saved or mined btc to pay for a miner. If you really think btc will go up, buy the btc with cash, then buy the miner.

Not sure I'm following - what difference does it make where the BTC came from? It's still the same amount that you need to ROI. Speaking of which - if you think that BTC will go up, why buy an overpriced miner that might or might not ROI in 9-12 months? BTC going up will just make it worse for ROI (likely faster difficulty growth etc).

the cost of mined a coin is not the same as purchased coin.

Much longer explanation is needed,but here goes.

I go to coinbase today right now spend 2k on coin and send it right to bitmaintech. my cost is 2k in btc and in usd.

If I sold 8 gpus at 200 each in btc on June 1 I made a gain since the coin went up in fiat so I would use less coin 15 days later to buy the miner.

same applies if I mined coins from april to june 16 to buy the unit. the coins went up in value.

Thank you.

The curse of having a degree in accounting. Being the son of an IRS auditor the husband of an IRS revenue agent and lastly finishing college while working in IRS collection division ( truly a really bad job).

It can be difficult trying to explain that bad and hold is in no way the same as mining.

Worse yet while all that I say may be true for USA accounting rules there are lots of places these rules do not apply.

Better to have 100 friends than 100 rubles

Sound report: Doing the Lowes filter trick raised my temps about 10%. Removing the fan guard lowered my temps 1-2C and made the unit rather quiet (at least relative to S7s or S4s).

Tried removing the fan guards from the S7s and had very little impact. Placing a Lowe's filter across the intakes worked great though. Since I have 2, side by side, I just used one filter and suction is holding it in place. Temps are up a bit but very inconstant now, varying from 53 to 63 between the 6 boards. Still that is in line with the S9 temps, so I suspect I'm fine.

I have still been testing different pools with 24 hour runs. This time I gave BTCC a try with the S9. During the 24 hour run the S9 hashed very close to the 14T as shown with extremely low hardware errors. Still no issues with pool comparability, which points to good news. The pictures below show results which I'm very happy with.

The full BTCC Pool statistic page is rather large with entire info so click here if you want to view it: http://i100.photobucket.com/albums/m25/notlist3d/S9/btcc24hour_zpsqailk5yo.jpg
Below is just the graph to show stability which you can see was very stable:

For some reason I had that video of the rat breathing oxygenated fluid run through my head just now...

But honestly, I am considering doing this to the S7; but I don't mind it when the fan speed is 30% and hashrate is 3.5Th avg....

But for the newer louder hotness they just released, and seeing board AND chip temps; I think a submerged cooled unit would be awesome. I could pipe it far away and outside easily to a radiator and sump tank. Just need pumps good enough.

Nothing a decent pump and a nice trip to HomeCheepo can't handle.

I don't want the noise with any more miners. The S7 is like an S3 that's fans are running full tilt... And that's all I'm willing to deal with anymore.

BTW: I live in a "confined space" with my miners. One of them is taken in and managed by me at home for a friend for a split of profit. A friend and I almost have our business model down for setting up small farms at locations with very very very little rent that happens to include free power to the tune of a 60A 240v supply line for each space rented..... Oah man... If only they knew what we have planned!!!

Is anyone here brave enough to do submerged liquid cooling on one of these puppies?

It would lower the maintenance and noise concerns for most peeps...

I know it's an involved thing but considering how well a mineral oil cooler works with a PC, it's work asking if anyone is considering this route.... Because if I get an S9 or something that is similar to the S7 etc; I'd rather take the leap to have it oil/liquid cooled as soon as the warranty is up.

I'd love to see some pics of these cards hashing away while submerged in some mineral oil.

And it looks like, due to heat and errors, a lot of the 14TH machines won't actually run at 14TH reliably anyway.

Just to add a data point, my S9 B1 arrived today. Had it up and running in perhaps 20 minutes (and headed to Lowes soon for filter and duct tape!)

It is running about 10C at the PCB level than my S7s, presuming the S7 firmware's temp is a PCB temp. However they are also higher in the rack, so may have higher temp input air.

I'm seeing a few (like 3 in 30 minutes) hardware errors, and about 97% of the advertised 14TH, so well within the +/-5%.

Cassey

ps: Mine apparently came with the June 8th firmware I see on the site:

it would be interesting to tally up S9 B1 performance so far. There seem to be some complains, but let's put some real numbers on this.
Please respond (if you want) with four parameters. If machine is DOA, obviously zeroes for speed.

1. Th at start, for example 1hr without mhz adjustment (if possible)
2. Stable Th
3. stable mhz
4. ambient temp

Mine is apparently hashing at advertised 14 TH @ sidehack's. I will be able to post some data tomorrow after I get home.

Now the money is free, and so the people will be

I feel....I feel many things. What is the price of an s7 after halving. what is the price of an s9 after halving. You see, these miners are priced on expected ROI mesured in 2-4 months on average, depending on btc price. after halving...won't the price go down to reflect the same rule ? so i'm guessing...im going to wait.

The jump in price works against B1 buyers just as much as it works for them, since to buy batch 1 you had to buy BTC at about 30% less than it's going for now. So someone buying a later unit for the same USD would have to mine back about 30% less coin to break even, which because of diminishing returns from diff increases will mean breakeven more than 30% faster.

If you can get one at the current rate... out of stock now. Not sure if Bitmain is playing games here but it's probably creating a sense of urgency for some buyers.

As for math early vs later, I prefer to look if you can mine the price difference in the time period between when those miners ship. I doubt Batch 1 will be able to mine a full coin before Monday when the first Batch 3 miners start arriving. The price difference was 4 vs 3 BTC. Batch 1 might have a slight hashrate advantage (14 vs 12.93) but I don't think that will be enough to close the price gap.

Reminds me of the tactic Chris used from ltcgear! Worked well for him. Sadly tho that turned to be a ponzi. Least ya get something here. Albeit again sold something not as advertised it seems. Feels like Deja vu!

Edit. Looking forward to bitmain supplying everyone with compensation in hash to the pool of their liking in the amount of hashrate The machines are short. Ahh there I go dreaming again;)

Seriously guys this is a joke. They gouge you on price. Loyal customers like yourselves and this is the treatment they give you?? Same bs last three miners I guess they won't learn if we don't. Democracy comes by where you spend your $

hmm which new psu are you talking about?? the miners with the psu mounted on the top? those are only supposed to reach 2.7th/s on the default config. or do you mean the separate 1600w psu (if so those arent "new") they sell? that psu only runs on 220v power i believe so are you sure your using 220v and not 110v?? try using another psu with 4 pci-e power connectors and hook 1 up to the controller and the other 3 to one of the boards. power the miner on with 1 board at a time and see what the hashrate for each board is. this will help you determine which board has issues.

Completely useless suggestions.

First of all, he lives in a country where is 230V electricity .
Second. I'm pretty sure he bought 1600W PSU.
Thirdly. S9 software shows each blade separately. Hashing speed and HV errors.
There is no need to disconnect anything.

I got my first five S9 and one is also "lemon".
Tomorrow brings courier another 6x S9 . I hope they are better.

Did you use multiple accounts to buy 11? Did you buy more than 11?

Also, does anyone have a link to the spec sheet on the BM1387? I can't find it on the site but I suspect it's there somewhere.
