That is impressive to say the least, phill would you please post a screenshot of both t17e and t17+ temps and fans?  I am confused about which to buy out of these three

T17,T17e,T17+, i have T17 running good, T17e on it's way but not a T17+ , my main concern is heat !

Summer here is really hot, i want to stack more of the gear that has the least temperature regardless of efficiency and price per TH among the T series, S series is a no-go.

I can do the  2 t17e's

I have a teamviewer set to the 2 17e's

Room is in clifton  super good air fans cooling

we are feeding the room filtered outside air it is 50f air right now.



full size of both units.

both do well at 53th
but  that area has filtered air.
stable internet.
temps now stay under 80f with input air at 2 sources both filtered.
we fixed power drop to 185 volts so power is good.

It is not  true data center grade but it is decent setup for mining.

I can not show the t17+  it is at a spot that I can not do a safe teamviewer connection

the t17+ is doing   64-65 th at 2990 watts
the t17e is  doing   53-54th at 3200 watts

the t17+ is cooler  it is better gear.

of course it is all about feeding it 3000 watts of stable power.  you need to be able to do this.

[mikeywith]

Seems like Bitmain don't have the T17+ which you have anymore, the only available type is the 57th



This one does not look much different from the T17e, which has the specs below.



The one you got does 65th at 2990w which is much more efficient than these two,that's about 46w/th which is just as efficient as the the S17e that does 64th for 2880w.

[philipma1957]

My t17e's do not do spec  they do 53th at 3200 watts  way over on power

My 1 t17+  does better then spec  it does  64-65th at 2990 watts  a little higher hash then spec  and at 46 or 47 watts more efficient then spec.

From Feb 2019 to Jan 2020  I ordered and my partners ordered lot of bitmain gear. 35 plus pieces

the 2 t17e's were the only gear under spec

the 1 t17+  did the best over spec.

They represent
 the best (t17+) close to  a full 5% better then spec

 the worst  (t17e) about 5% worse then spec

Does this mean  you should buy t17+ ?

I have 1 coupon left  I plan to buy this unit https://shop.bitmain.com/product/detail?pid=00020200107140204896zxU627b8066E

a t17+  for 1011  due to ship feb 11.

I am waiting for my last unit on order a s17 pro to ship  due to ship jan 11-20.

Our last order was T17+ 50 THs - batch February 1-10. We still didn't receive it due to coronavirus. Seller now offers a change order to T17 40 THs, which were manufactured in Malaysia. That way Seller can send it next week. Otherwise, we need to wait more, as the Bitmain factory in China is not operating at full capacity.

If they are offering a good coupon or $ difference in return with that T17 40TH/s, I'd accept that.

[xiver88]

We have accepted the offer. Because more machines were offered to compensate for THs loss.

[philipma1957]

Please continue to follow up. I would like to know how fast they come and how well they work.

Also I mention that some do use aftermarket firmware on the t17  so if you decide to do that let us know if that works well for you.

[Biffa]

Interesting T17E problem raised its ugly head. Don't think its limited to this particular model but most of the *17 range.



Log file looks normal up till the moment of outage, when it switches from temperature readouts to errors reading the temp chips.

This is after over a month of uptime with no errors.

Anyone expericed something within the lines of:

t17e 53th

I doubted the sensors have all died, as after a forced reboot (unplug and plug back in) it works again, a couple of days max and then again the hash has disappeared.

the machine keeps running though.

Bitmain where kind to reply and gave me the SD firmware to flash on it.

To continue...

Any help, as always, is appreciated.

@AlecMe

I went into great detail explaining the cause of this issue in my topic but let me summarize the part which matters for you, you have a faulty PSU.

There are mainly two types of sensor errors, one which fails to read temps on all sensors on all boards (your case), this is without a doubt a PSU issue, the other one where only a single board fails to report temps, that board has a bad chip/heatsink.

In both scenarios, you should always Sdflash that miner and then flash the latest firmware, if the problem remains, then for your case, test the miner with a different PSU.

[mochaaa]

There any undervolt/overclock firmware for the T17e yet?

[mikeywith]

None that I am aware of, the only reputable custom firmware I'd trust would be Braiin's or Vnish (Asic.to and Awesomeminer), you shouldn't trust any firmware without doing your due diligence.

You could contact taserz (Asic.to) or/and patrike (Awesomeminer) to see if they have any plans to support the T17e.

[mochaaa]

Wish I would have known the 'E' variants were more time consuming for firmware...

[minefarmbuy]

I believe vinsh has fw for all variants but yes double check. We're hoping to partner with a dev since the 17 series aren't compatible with multiple (over three) coinbase outputs.

[favebook]

Vnish doesn't have firmware for "E" versions yet AFAIK. Waiting for one as well.

[kano]

I believe vinsh has fw for all variants but yes double check. We're hoping to partner with a dev since the 17 series aren't compatible with multiple (over three) coinbase outputs.

So instead you're going to parter with someone who will be violating the cgminer license.
Wow - great - thanks very much ... scumbag.

@kano

So does Bitmain firmware, and so does your mining pool by allowing firmware made by Bitmain and Microbt which refuse to release the source code, there is no difference between all of these firmware versions as far as Cgminer license is concerned.

On a side note, refrain from posting twice in a row as it's against the forum rules, and your second post will be deleted or merged with the first one in the best-case scenario, and then you will likely accuse the mods of having a biased approach towards your posts which break the from rules.

Go read the GPLv3 license that governs cgminer.
You do not know what you are talking about at all.

You are not a mod - so go find someone else to annoy.
If a mod combines my posts - then so be it - I'm not concerned - and it will probably be Frodo so he'll make more btc from the forum for doing it
