Are the T9+'s a good investment at $1500 including shipping. They same to be quite more reliable than the S9.
Not at 1500 considering they were selling for less than half that if you had a coupon, and they're still in stock direct from Bitmain. I'd suggest trying to find a coupon and buying direct from Bitmain, as they are currently going for $771 with a PSU.

I'm sorry I meant 1150$. With cost per kWh around 9cents
You're going to break even in just over a year if BTC prices hold and difficulty also holds. The latter is extremely unlikely, and because of that I would suggest against it. Difficulty's going to kill you in the long run and draw out your break even time by a lot. Coin prices may rise, but you can't count on that when mining.

Tbh i guess bch should rise by the end of summer.
If you think prices on BCH (or even BTC) are going to rise in the future, it's a better option to just buy some BCH and hold versus buying a miner and mining BCH considering your electrical costs and the cost of a T9+ for you.

I advocate for mining, but in your case buying and holding makes more sense if you think BCH will truly rise.

Thanks for your help. I'll consider my actions.

T9 looking like an absolute bargain, im wondering whether these prices may go back up when the BTC prices returns to 15k+?

It does appear that bitmain adjust costs based on btc / ltc prices, makes sense that they price like a commodity

What's with the fan and power consumption? It is no really for home use, is it? Huh
No. It is possible to run these at home but keep in mind they are extremely loud at near or above 70db, and they're built to run on 220V though I know some people have found ways to run these on 110V. Some people even manage to sleep in the same room as these miners. How? I don't know.

There are ways to reduce noise, like with a wind tunnel philipma1957 built, but don't expect these to become quiet. I ran S9 these in my garage, and they were still somewhat noticeable from the house.

i think they figure the reason of high S9 hashboard failure
it's the power needed for the chips!
so they produced T9 with 180 days warranty
each T9 board have 57 chips instead of 63 and need 480W to power instead of 400W
less chips more power!

You cant. ASICboost is a hardware level thing, no software is going to make it happen

I sent a dead T9+ back to Bitmain (USA CA address) and got the notification that they received it.
Does anyone have any experience with the turnaround time for repair / contact back from them?

Thanks,
Dave

Give it a month. For me it typically takes between 4-10 weeks. If it's out of warranty watch out for the repair order that you're gonna have to pay.

i sent T9+ back to hong kong, courier service delivered the faulty miner on 6th Aug 2018, bitmain updated the ticket to "Collected" on 7th Aug 2018 and sent out replacement on 11 Aug 2018, i will say their support team at HK/ Shenzheng are very efficient  Grin Grin

Any differences between T9 and S9?

Power Consumption:

T9 1450W 11.5TH/s
S9 1078W 11TH/s (Batch 22)

The big difference for me.

Got my replacement in the other day.
Very used miner, with a bad fan.  Sad
Put in a spare fan that I had and it's off and mining. But come on do a little QC on it.
That or DHL dropped it. You never know.

I think Fan 3 was taken off a small jet :-)

Seriously, anyone have any idea on what can be causing it so show that speed?

Temps are good, it's been up and mining for 2 weeks now since I last changed pools.
Checked in today to verify all was good as I got a notification from my secondary pool and saw the speed of a fan that does not exist.



Thanks,
Dave
