Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 258. (Read 451048 times)

With a temp gun I'm reading about 75c on the back of the boards (the side without the heatsink).

i was sitting by the pool in my hotel today and wishing the exact opposite.

 

Thanks, pretty cool.
Wish it had a top though.

no problems here. after 50min its averaging 1.16TH and looks to be similar results at the pool (eligius needs 3hrs to give a good stat though)

conclusions: good miner, easy to use, but could use some improvements to reduce the power draw and fan noise to make it good for the home user. (ITS LOUD)

Why does everyone on here require muti-terahash miners.

I am quite happy with smaller units of 500 to 1000 Gh.

When the "Magic Smoke" appears from these things and their power supplies(apparently quite often)

then I think myself lucky to only loose one unit, or more often only one board.

360 degree view can be seen here! (might take a few seconds to load depending on your internet):

The temperature measurements are relative to the type/location of sensor being used, but you're right 60C is pretty cool still.

My S5 is running in a 40c room. The chips are right around 60c and working perfectly. 60c seems quite cool, so I don't expect any issues at that temp. I can hold my finger on the heatsinks just fine.

The C1 only doubled the hashrate because they doubled the boards. 4 boards to the C1 vs 2 boards for the s3. They could do this because of the ability to fit 4 boards into the existing cases of the s3's with only minor alterations. Now if they were to double the boards(which would double the chips) then it could be a 2TH/s machine, however that is a lot of heat in a very small case, I don't think it would be possible to dissipate the heat fast enough with 4 boards so close together. The chips might be fine but the rest of the PCB would probably be toast quite quickly. If one were to mount the boards into something like an S4 case, that would allow enough room to create in theory a 3-4 TH/s unit with a watercooling block sandwiched between 2 boards. I would say 6 boards total for approx. 3.3TH/s keeping in mind the need for 2 separate PSU's to power the boards, and enough room for cooling lines to be run, fans to cool the PCB's and an extra controller (unless they develop one that can carry more then 4 boards) At max I could see potential for 3.8-4.5TH/s machine setup as the chips can be chained up to 256 chips, but I think that would take a lot more R&D. Also I don't know about pricing. It would be really cool to see something like this, however the cost would likely skyrocket with this type of setup. One can dream though.

If bitmain cared to donate enough boards to me, I could see what I could come up with......... 

it likely would be 1.6TH/800W as 800W was about the amount of heat the C1 could handle. 2.2TH/1.1kW would likely be too hot

please make it double the s5 hashrate, as c1 double the s3!

Hi sk8erskid420,
Partner received the PCBs and control boards already, is developing the liquid cooling solution. Wait for update...

Hi Gents,

What is your average ambient temperatures?
Here in South Africa we have been experiencing temperatures from 27-39 degrees C.
My S1 was running at 51-54 degrees. I read that the units should not reach 60 degrees.

I was looking at the S3+ units here in ZA. They are selling for $478 (R5200).

So that made me think I should start looking at the S5.
What temperatures can be expected from this beast?
What is the average and max temperatures for this new unit?

I had a thought, now please remember this is just a thought and probably not to practical(cost efficient) for the home miner, but what about a waterblock cooler, something similar to the C1. If the heat is dissipated by the top of the chips then this should be an easy application, perhaps not by us, but perhaps bitmain in future releases. By that I mean it wouldn't be worth the cost for a home miner to buy all the required parts to watercool. if they could machine a waterblock that could intake/exhaust the coolant at the top of the block, perhaps intake at the top back and exhaust at the top front or something like that, then one could still stack sideways, cool extremely efficiently, and run a full loop system that could cool perhaps up to 3-5 units per radiator(haven't done the math, just spitballing). In theory I would guess that at stock speeds, this would keep the chips running under temp compared to a fan setup. Also as a bonus I would think a single fan used as a booster cooler to cool the interior of the unit would be an idea. Just remember this is only an idea that popped in my head so please do comment, I'd love to hear what others think of this, Good or bad. I'll prob post this in a few S5 threads to get some extra feedback.

Philip1957 wasn't too keen so far either.

other than Pat has anyone else gotten any antduds?

Bitmain always seems to have a poor start with new models and then improves with age. Hope the S5 goes ok for you Xian

I've got a bad feeling about S5 B1's... Fuck that's bad. Surely it was merely "damaged in shipping"

ಠ_ಠ

My S5's just landed in Cincinnati, so with any luck, I should have my own review up by Wednesday.

Don't turn the BBB around.. lol..

I agree with klodike, everything he said.. take a breather.. then I would try swapping the ribbon cables, and pay close attention to the orientation.  move the cable from the good board to the bad one..


Rich

take a break. sometimes ideas come to you. My post was just to make sure you eliminate a bad ribbon cable or bad connector on the controller from the possibilities. Otherwise its likely that on the bad board the fault is in a component that drives both chip chains, as it seems strange that both chains are dead (ie: less likely that at least two hashing chips failed in a short timespan)
