I'm suggesting that the T model is basically just as reliable but it is in some way a model made from the less desirable cuts from wafers. Could there be in any thing resembling the truth in this or am I completely off the mark? I've not paid attention to mining for two months and I've forgotten a lot it seems.

Long story short: What is the fundamental difference between the T and S series?

Hi guys, thanks for the replies. I was wondering if anyone had any remarks on the much more wildly speculative part of my post. Whether it works out that the T model is just a model made in lesser quantities from the mishandled/malformed parts? Surely there are waste/scrap parts from making an S model that are still somewhat valuable? Bitmain is too 'insert adjective depending on your opinion of bitmain' to throw away?

Yeah I have only the one 53t pro which pulls 2225 watts so 2225/208 = 10.7 amps

but we run around 227 volts so 2225/227 = 9.8 amps.

All my 30 amp circuits to l6-30r are 10 gauge under 6 foot runs. So they can do 5000 watts 5000/208 = 24.04 amps.

every once in a while we shift to a low leg and volts drop as low as 187 fucks up everything.

I am working with power company as to why it happens.

With us gear drops out and comes back since the low volts do not last.

the danger for a steady draw setup is if the low volts lasts for hours

Are these drops possibly due to Power Company changeover from one transformer to another? In one of my locations, I'm pulling 3MW off a residential substation, but I'm the only "commercial entity" drawing from that portion of the grid, I've been lucky to have very steady supply flow on the power company side. I know some residential grids can have decent size variances on their supply side. In my other location I'm pulling 4 MW's off the HV lines at through a 3500 KVA Transformer to 480V and stepping it down into containers to 3 phase 208. So far I've had very good results in my container build outs. 480V down to 208V into 10 gauge runs on 400 amp panels loaded with 30 amp breakers. Very stable so far.

I'm also kind of dancing a fine line. I had a 250' roll of 12/3 on hand already, so I wanted to use that rather than spend more money on more wire.
My run is only maybe 10-12'.

12ga is safe up to 20A, but they recommend only using 80% of that capacity. So 16A.
I ran two circuits, 3 outlets per circuit.

Per Bitmain site, the S17 56th (pro-53 a little less) uses 2520 watts in normal mode. 2520 watts at 240v is 10.5A. So, 5.25A per cord.

So, in my case, i can run 3 S17's, plugging into those 6 outlets, putting 15.75A thru each circuit.

I'm running out of space in my breaker box at this point, so if I decide to add more miners, I either have to wire up a sub-panel for miners, or consolidate some of the 15A 120v circuits with tandem breakers.

BUT, now I ordered the S17e, think we're looking at 2880w (12A)....... I might be swapping out to 10ga wire.

Currently running (1) S17 56th, (1) S17 Pro 50th, and (1) S9i.... when the S17e arrives in November, the S9 will be sold on eBay.
Depending how the near future plays out, I'm considering expanding a bit and running up to (5) S17's

My set up is more recent - mar 2018 so all the wiring even the receptacles are fully 10gauge ao i will be ok with that

I am currently running several S17 56TH on 208V. I have randomly Amp Clamped over 20 of them at the lead wire coming from the Breaker. These units are pulling consistently 12 Amps. We all used to easily get away with using 12 gauge wire, particularly in our receptacle;e pigtails. ( so much easier to make them up ) I am rethinking this part of my grid build outs now. These new units are consistently into the double digit amperage's. I believe that 12 gauge COPPER wire can support these loads but due to the constant draw aspect of our game, it's a bit of a game of Russian Roulette as to when your wires heat up, and melt their clothing. IMHO, it's not worth the risk to save some sore fingers from twisting 10g to 10g during rig ups. 2 S17's on one 30amp Breaker gets you right at 24amps +/-. Perfectly at the 80% threshold. Run that on 10 gauge and you'll avoid that awful smell of burning electrical components. Oh....and also burning buildings. Wink

( side note; When I amp clamp th T17 38 th they always come in under 10 amps. Again, running 3ph, 208V )

yep

let me find links
this meets most codes and you do not need pdu's

1x 30 amp circuit breaker
https://www.amazon.com/Q230-30-Amp-Double-Circuit-Breaker/dp/B00002N5HJ/

use 10 gauge wire to the receptacles

two receptacles

two extensions

two splitters
https://www.amazon.com/IEC-C20-C13-Splitter-Cord/dp/B07J6S348C/

two t17's

https://shop.bitmain.com/product/detail?pid=00020190918155345657Yn1i4Xvb06CC

that should have you at 4400 to 4600 watts easy peasy only 18-20 amps

now you could do

1 t17e and 1s9 that is also about 3100 + 1300 = 4400

or 1 s17e on normal speed and 1 s17 pro on low speed 3000 + 1430 and 4430 watts gives you 105th

so yea, 2 T17's per circuit then right? iirc T17's are right around 10 amp's each.

Iirc, 10ga is good for up to 30A, and they recommend only running a steady load of 80% of max capable amps... so you'd be good for 24A steady load on that entire circuit.

Also need to know what gauge wire runs those circuits. Some people don't always wire to code. (Me for example).

I only have an 8' run from the breaker box, which eases resistance, so i was able to run 12ga wire which I had laying around, to 3 outlets per circuit, two circuits. So I can pull a constant 16amps per circuit safely, with no worries, and still be 'technically ok' to 20a. So I can run 3 units. Anymore and my wire run the risk of glowing.

But, knowing we have a Y-plug available, if I run more circuits in the future, I can wire less outlets to a circuit. And that's where I get my fingers chewed up.

without pulling the paperwork to verify and going off of memory, I would have to say the wire is 10 gauge

my circuits are 30 amps currently with 4 outlets on each circuit so 4 might be too much maybe 2 17's and 2 s9's

S17 53th pro pull 2250. So two do 4500 which is easy peasy for a 30 amp circuit. Easy way is circuit to a pair of l6 30r then a l6 30p to c19 cable then a c20 to y c13 it does a pair of t17 or s17 but I would not try a s17e with a s17 pro as that would be 5500 watts.

Just be careful with your calculations. Although you can double the units with the Y splitter, you'll also double the amps pulled on the electrical circuit. And depending on wire gauge of that circuit, could be an issue.
In my case, I'm maxed on circuit amperage for the circuits I have run. To expand my operation would require running a few more circuits, which will require a lot more breaker box work.

ahh - I need to look into that Y splitter - I could run 20 of the 17's vs 10 of them, as I am running power wires from two outlets. I installed a switch that shuts both on/off at the same time and they are the same circuit so if the breaker blows there is no issue with powering one and not the other but the splitter would allow me to run quite a few more.

'The right to privacy matters'

Back in the day T-9 adverts said it does not break and is reliable.

t-15
t-17 don't say that.

I have

1 t-17
1 t-15
1 s-15
1 s-17 pro

In a world of magic where everything is according to phil I would only have s-17 pro's 100 of them would fill the power we have

200 would fill us if we max the power to 400kwatts

my s 17 pros does 36 watts on low speed nothing touches that better yet 1440 watts I use a y spilt power cord made for 14 amps and it is an amazing unit.

But thr price of it is a big factor.

which is why my next order is 2 t17e's for 3300 vs 2 s17e's for 5100+

I think you pretty much got the difference - it will be slightly slower but will have a lower efficiency as well. That said, all my 15's and 17's are T versions. For me, the small difference in efficiency does not make up for the price difference when the prices are 50% higher for the S versions.

My goal is to increase my hash rate but to also make ROI as quickly as I can. The extra efficiency do not always make for a faster ROI when the price is higher beyond a certain point. AT least that is how I justify whether I buy the T version or the S version.

Hi guys,

So I could not think where else to put this but reading about the S17e and T17e on a Chinese website:

Quote

It is reported that the standard calculation power of S17e is 64TH/S, the energy efficiency ratio is 45J/T, the standard calculation power of T17e is 53TH/S, and the energy efficiency ratio is 55J/T. With high computing power, low power consumption, strong stability and high cost performance, the S17e and T17e are on the market. According to official website data, the ant mining machine S17e is only 1 minute from the time of sale to sale.

*Sorry for translation by google, and if there is better translated info but it's just a quick question..

I used to get the impression, and I think I have read, that the T9 model was like the more reliable version of the S9 model. It's cheaper, and lesser in every way but somehow I got the impression, and maybe I did not read but somewhere along the way made up, that the T model is the more reliable miner. Reliable in the sense, and only this sense, that it does not break as much and is longer-lasting if not necessarily more hardy.

Reading this section in Chinese it just strikes me, as someone who may not understand the process particularly well, that the T model is just a weaker version of the S model as a result of something on the assembly line. I'm suggesting that the T model is basically just as reliable but it is in some way a model made from the less desirable cuts from wafers. Could there be in any thing resembling the truth in this or am I completely off the mark? I've not paid attention to mining for two months and I've forgotten a lot it seems.

Long story short: What is the fundamental difference between the T and S series?

This is flat out an attack on the whatsminer m20s

now does bitmain know something we don't know?

Huh

I have zero idea.

if coins go up this deal is still better if you are using bank transfer or coin purchased to buy this gear.

I am still waiting for a coupon on my s9k gear.
