Title: Innosilicon T2T 30T review
Post by: Procaius on August 18, 2019, 05:23:59 PM
Well... after an absurdly long wait (miner ordered June 28th directly from Innosilicon), my T2T 30T finally arrived on August 12th.  The stupid courier actually left my miner on the front steps of my house (while I was 1500 miles away on vacation).  Thank goodness my neighbor wasn't far and picked it up for me.

The miner is running very well.  Averaging 26T in balanced mode with an average temperature of 58 celcius.  The miner came loaded with the latest August firmware which was nice.   No update required just plug & play.

Why do people deliver like that? LOL

Interesting as I had the same batch as you but had to upgrade to '7th of August 2019 07:03 AM' as the preloaded one was 1 weak earlier (1st of august or something). On the downside, the previous version was doing 29.5ths in factory settings, the new one only 29  ???

I am doing factory settings and hoovering around 29ths at 80 to 82 degrees but at 2450W ~ 2500W at the moment.

How many Watts do you pull from the socket?

innosilicon  usually misses specs

so 2500 watts at 29 th  is about what to expect for gear rated  30th  and 2200 watts.   if you are in a cold spot like 70f or 20c

you would be closer to  2200 watts and 30th


their gear tends to work without breaking.  and they have been known to deliver late.

Welcome to the world of  asic builders.  late and off spec  is common.

a lot of asic gear runs better in a 15-20c room  or a 60f-70f room

It does seem like a rock solid unit, I put emphasis on rock as it is heavy as F**K.

I'm in northern Canada with cool temps so I bumped mine up to Performance+ shortly after posting my original message and now its average hash rate is 30.04 and chip temp is averaging 68 degrees celcius with fan speed at 65%

I currently don't have any way of measuring what wattage it's gobbling up and frankly I don't wanna know!    :o

For the low temperature of 16 - 20 Celsius I can only say: Winter is coming  ;D soon

How did you get the fan to 65%? I believed they are 'blocked' at 100%.
I am curious how many W's you are pulling  :D

Also, managed to reduce the vibration from it (and decibels by almost 10) by putting rubber legs (found on an old fridge compressor) under it.

Always nice to meet another one, though I'm really only north of Ontario these days. So far your delivery experience sounds like anything I ever receive from DHL, someone has to be home, they even mess up my hold don't deliver requests.

Believe it or not I built an 8' x 12' shed and had it professionally wired for 240 volts.  I've been running miners in it for about 12 months now and it works great.  Even throughout our frigid Canadian winters.  That is how I kept the fan at 65%, the day I wrote that post it was like 12 degrees celcius outside (53 f).

One of the reasons I put it in the shed is the noise, the other is the heat.  Believe it or not we do get some pretty warm days, even up here in Northern Canada.

I'll have to look into building that meter, thanks.  I love DIY stuff and electronics (which is why I got into mining in the first place).

I'm in northern Alberta.  Very nice to meet you as well.

One update on temperature:

I've changed the exhaust ducting from a 4" (was waiting on the other one to be delivered and this was the only one available) to a 5".

Overnight around 14 degrees outside and a good airflow I've managed to get 65/67/67 degrees on the boards with the fans at 95% (first time ever, but still room for improvements) down from 76 to 84 degrees.

The interesting part is that the miner shows 28 th/s now (still on factory settings, just a restart involved - guess is it now outside its +-5% tolerance), but will check the pool after 24h due to the restart.

I might try and post my fridge build, as I am mining home in a back spare room and managed to reduce the noise relatively well.
Of course, if there is interest

These things love a LOT of air flow.

I built a silencer box inside my shed out of drywall and I keep it cool with 6" ducting and this 440 cfm 6" exhaust fan:

Nice, I wish I could get power rates like you guys or at least have options for providers. I was actually Jasper this past March, beautiful drive up from Edmonton.

If you get around to it you should post some images of your setup, we always like seeing new ones. This is what I set up for my garage this year Summer Mining - Home miner (https://bitcointalk.org/index.php?topic=5163623.0).

2360W at the moments with 22 - 23 degrees celsius room temperature, plenty of 'fresh' air, vent at 100%  :o , 28.12 th/s, board temp 67/69/69 uptime 9h (due to power failure, was 10ish days prior at almost 28.7th/s).

It might be a good workhorse but the vent is driving me away from linking it  ;D

Edit: factory settings at the moment.

Post by: judypug1956 on September 02, 2019, 07:54:44 PM
are you on factory setting for the 2360/28.12

pretty typical for inno off 5-10% on power and off 5-10% on hash

you should try

 balanced
 Balanced+
 Balanced++

Every inno I have owned has been off 5-10% on power and 5-10% on hash

they all like balanced better then factory unless room is stupid cold
they all run the fans too fast.

I am waiting on that 50t  to ship so far it is two days late.

The same way one simulates the fan(s) on any miner - by making or purchasing a fan simulator. Search Amazon et al for them. Another way would be to get some old fans, cut off the blades and run the fans in the fluid (but out of the way of flow) with just the hubs spinning.

T2TZ is the 30T version of the T2 Turbo.

I thought you might all find this interesting.  I emailed Innosilicon to ask them what the maximum safe temperature is to run these things at and here is their reply:

Quote from: Innosilicon
Dear Customer,

Thanks for your email. Please be noted that usually temperature for working chips is around 70°C. When temperature goes above 90°C, problem will occur and miner will shut down due to overheat. Please keep the environment cool and improve heat dissipation of the miners. Appreciate your understanding.

It is under 800 so no trump tax legally.

It may be the best new gear under trump tax.

I'd agree with you if it wasn't for them being so hungry. 27-30THS and drawing over 100-200W more than an A1047 (in "normal" mode) makes it a no-go for me. Ja price is good but that power draw would null out the price difference in less than a year.

which means fuck you phil and anyone buying from them.

So I was shouted at by biffa to just get a s17 pro  I went to bitmain  and decide to order a s17 53th  and used paypal to pay it off.  Six months to pay it down.

23rd of September 2019 07:46 PM
Platform Version
t2tz_soc_20190923_194636

Can be updated in miner (mine does not work) or can be downloaded from miner link and selected manually from download file to be uploaded to the miner (i did mine like that) in the Maintenance and by going to the Firmware Tab.

Took around 5 minutes to reboot and the equivalent of Tunning to be up and running in full.

Currently doing:
27.45TH/s for 7 days in miner status
28.120 TH/s for the last 24h in Pool tab (this was constant)

26 rejected shares

Temp for boards 62/63/63 (celsius) constant

Room temp 25 degrees celsius

Ohh yes, and vent running at 100% as always  >:(

I have it running on Balance++

Wattage unknown as my socket measuring gear nearly caught fire at 2.5kw after a few months

Edit: Not sure about my ROI on this machine, will do the math and upload later but I doubt anything will ever ROI like S9j  ;D

Okay. So you have access to amazon.ca I will look for a link or two for you. This unit can pull 2400-2700 watts so you need a 14awg wire for the c13 power cable. What amp circuits do you have in the home? Do you plan to do a dedicated circuit.

go to amazon.ca type in c13 to  nema 5-20p cable.  There are a few 14awg then type in nema 5-20r they have a few one socket receptacles. This would need a 20 amp circuit breaker and you can run one unit with no issues your in the wall wire needs to be 12awg.

Particularly looking for Inno T2Tz (30TH) device.


Title: Re: Innosilicon T2T 30T review
Post by: AlecMe on October 13, 2019, 06:48:51 AM
Default SSH username/password for Innosilicon machines is usually one of the following options:

Code:
root/innot1t2
root/t1t2t3a5
root/blacksheepwall

but according to a Reddit post, these do not work for a T3 (https://www.reddit.com/r/BitcoinMining/comments/byno4o/innosilicon_t339t_asic_root_password_wanted/eqppj8o/)

as I'm on Mac, will try them later today using Cyberduck (easier to install than Putty)

Let me know if one of them work if you get a chance to test prior to me.

Also, does anyone know if SSH passwords cand be changed/access disabled through the firmware update? I believe Bitmain can disable SSH access, but not sure about the password change.

Also make sure you don't update the firmware yet, as a measure of precaution.


Edit: it appears they do not work, and in the same Reddit post above someone mentions that they have attempted to get the login from Innosilicon directly and were refused on a 'customer safety' reason

HI all,
I went to home depot(Canada) to try to get wiring for the T2T, but they were not able to identify the correct wire that I should use.
Can you provide details to what wire I should purchase?  A home depot link would be great!

Appreciate the help!

Post by: Steamtyme on November 01, 2019, 10:26:28 PM
What do you mean you want to make up a power cable? Or are you trying to wire up a circuit? I'm in Canada as well, and generally order in Power Cables, Home depot doesn't generally have the cord ends to make one up yourself. If it's the power cable you will need something like this https://www.primecables.ca/p-361208-cab-pw-141-all-nema-6-20p-to-iec-c19-power-cable-12awg-sjt#sku371493
The outlet end depends on if you have a PDU or what type of outlet you have installed on what type of circuit. The more info you can provide the better. Do you have the power cable it shipped with? If so you can cut off the foreign plug type and replace it as well.

If you are talking about your electrical circuit, you need to have a 220V line 15 Amp circuit minimum. This would have to be the only machine on that line.

Edit: Just noticed some of your posts above. The wiring for your circuit should be 12/2 wire. If you say this Home depot will know what it is. 15 or 20 amp breaker on the circuit - it will be a 2 pole breaker. I will say if you are not sure what you are doing it is best to hire an electrician to do this.

New experience with the gear:
This morning, a very loud noise was being made by the ventilators (dB sound meter was reading almost 90 instead of the usual 78~80 decibels), so I started to make some notes.

The running parameters and temps:
Th/s: a bit under 27;
Vents: 100% (as per almost 95% of the time) - no surprise there;
Firmware: 23rd of September 2019 - needs update;
Room temp: 20 degrees Celsius (68 F );
Hashing board temps: 59, 60, 59 Celsius (a bit too hot due to low room temp);
Performance settings: Balance++;
Wattage: Not known as my reader burnt (to big load for the normal £10 eBay/amazon one);
Airflow: plenty available;
Running time: 18 days without a reboot.

So far the reason/s for the extra sound is unknown and as a solution to it just the classic reboot.

It appears to be running within the 78~80 decibels again.

Has anyone else experienced this?

Also, new Firmware is out (t2tz_soc_20191023_073403) 23rd of October 2019 07:34 AM , which can be found here: http://www.innosilicon.com.cn/download/t2tz_soc_20191023_073403.swu , updating mine now.

Edit: It appears the Upgrade Now button does not work (it will now start to download the new firmware, but the download link works), so I went manually in the Maintenance tab on the left and selected Firmware.
In the Upgrade screen select Choose File and hit Upgrade Now.

It took less than 1 minute to update (not including the download and reboot time).

Did you notice any changes?

it appears the massive bang was from another miner who 'lost' its ventilator pallets and these were creating like a rattling sound. ordered a new vent and hoping it still works and nothing else was damaged.

The t2t still works, luckily it wasn't it and after the firmware update and room temperature dropping to 15 celsius the miner fans dropped once to 80% (a true Christmas miracle  ;D) and now hovers around 80% to 85%.

It appears to me that the target temp for the hash boards is 59 celsius or 138 F thus giving me a finally a bit of lower % on fans ( https://imgur.com/ttSLalm (https://imgur.com/ttSLalm) )

Nice 80% fans.

Now if they only used a target of 65C for the boards  then you would be sitting pretty.  Fans would lower to maybe 70%

My T2 T24  is 15 months old with no issues  and fans run at 100%
My T3  T39  is  5 months old with no real issues and fans run at 100%
My T3  T50  is  2 months old with no issues and fans run at 100%

two underhash and        over watts
one hashing on spec but over watts

I would grade  the gear at a   B or B+

Yea Oct fw is most recent. I wish there were notes on the updates. Currently one t30z balanced ++ hitting 28.5 and the other on factory pulling 30 pool side. Would have to measure wattage but prior factory was 2300 on both.

Interesting as my Factory setting was doing nearly 30Th but pulling 2450W. But outside was warmer and, of course, vents were sitting comfy at 100% with the internal temp at 68 to 69.


On Balanced++ mine has stabilized at almost 27th (slightly under), if you are getting 28.5 well done  ;D. I wonder if it's better chips that they have used?

Definitely curious about your wattage, especially on the one that does 30t.

I have emailed Inno about the changelog and will update here accordingly.

Edit:

They have replied:

Dear *****,

Thanks for your email. Heat protection has been improved and miner hashrate has been optimized for the latest firmware.

Hash rate improvement is justified  ;D, not in my case though, I must have pulled the short string on the chips  :D
