Frankly, when I first ran the numbers for the S9 there was no way they were going to see ROI in any kind of reasonable time frame.  Now with big spike in BTC prior to halving these guys that jumped on B1 are looking like they may have a shot at ROI in a year.  It all depends on prices continuing to go their way.  Right now it is looking a LOT better than it did when they ordered them.   So the big gamblers it may pay off for them.  Time to grab the popcorn and watch... I know the BTC price is making me wish I had gambled a little... LOL

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.

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

how S9s are holding up in high ambient vs lower (at night)?
Rolla is at 97F, same as Houston, although we are at least 500-600 miles south.

EDIT: BTW, if we stay at least at $750 through halving, network will not drop 20-30%, but no more than 5-10% (if that), making existing S7 quite profitable even after the halving (maybe at least for 2-3 mo longer)
EDIT2 darn it, i just refreshed the page and btc is at $772

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.

The thermometer on my workbench right now is reading 96F. Oh, just jumped to 97F. That's not even in the sun, or in the hosting room. Heat sucks. I turned S9 clocks down to 625 yesterday and now chip temps are still 99-103C.

SP20/SP30 chip tolerated up to 115C on the chip quite nicely (throttled at 125), so i think that 103 should be OK (theoretically) as long as PCB is below 75C.

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).

What a dissapointing miner. Got 5 pcs S9`s and only 1 is working 100% even after firmware upgrade.
1 miner is running only 2 th on 1 board another miner is only running 2.4 TH on all 3 boards and 2 are completely dead. I bought even the new Bitmain PSU with the miners...
Holy moses im dissapointed.

FW upgrade? Was it recommended?

My S9-B1 is hashing ok but its running hot but now stabilized at 525mhz@11TH, out of box 13.4TH

If I provided you good and useful info or just bring a smile to your day, consider sending me merit points to further validate this Bitcointalk account.

I haven't looked at in detail, but the BMminer build is one day newer than what was shipped on my Batch 1.

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.

Hope dies last, but the important thing is that it dies.
I've got three of em. I have to downclock to 525, 575, and 625 in order not get too many HW's (new Bitmain PSU's)

Mining almost works as a hedge against a price drop. Mining from late 2014 to fall 2015 led to great returns as difficulty was relatively flat.

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.


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.

Only if your miner can beat BTC ROI.

Otherwise you lose even more $$ in price drop as you have fewer coins than you started with, and they each have less value.

I guess the logic is that if price falls the miner will beat BTC ROI.  Yet another risk...
