Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 187. (Read 451277 times)

What fan has the lowest dBA fan with acceptable CFM?

Thank you for your response.
I'm selling my GPUs already, some have been even sold. But somehow I'm a little bit afraid to switch all into Antminers. I somehow got used to my GPUs but seems that era ended for me . As I stated there is no electricity costs for me. And right now I do own 2 EVGA 1300 SuperNOVA and also the Corsair AX1200i. I don't have to buy them anymore. Did you have room to overclock your S5s with the EVGA? For the Corsair I guess this is what will be the problem. Guess I will have to underclock. But first I will run about 4 S5s. All powered by the EVGAs. Eventually I'll get a 5th, which will be hooked onto the Corsair and maybe a 6th one will follow. But that depends. Maybe next month or later, and if it will be still worthy then is the other question. My main concern is just about the noise. Did anybody measure decibels on the s5s? Right now even my 290s go up to 70 db. Guess sooner or later I will have to swap the fans on the S5s.

Yes you can run 2 S5 off of 1 EVGA 1300W Gold Supernova. The 2 S5 at factory 350MHZ pulls about 1200W at the wall. I would not recommend the Corsair 1200W simply because the cost difference is not worth it $310 Corsair vs $170 EVGA 1300W. The efficiency difference between Gold and Platinum PSUs is slim, and you would probably end up getting the same efficiency because the Corsair would be at 100% load, where the EVGA would only be at a 90% load. Also you have zero room for overclocking on the Corsair and you might even need to underclock to fit both.

I have smaller fans on mine and they pull together, 1170W at the wall. I'm running 120mm Delta replacement fans that push about 150 CFM.

Its an old title from a different BTC price.

Why the topic title still show that the price of S5 is 0.25/GH while it is not.

It is 0.32/GH.

It is 0.32/GH.

I have been running them on Nicehash lately. But as I meantioned, I don't have to pay for electricity at the moment. But the circuits are limited, I actually don't know how much I can after all plug into the wall 

I couldn't find out now at all which were good fans to hook up on the S5s to keep them more quiet. And can I power 2 S5s with one EVGA Supernova 1300, or even with a Corsair Platimax 1200i? http://www.corsair.com/en-us/ax1200i-digital-atx-power-supply-1200-watt-80-plus-platinum-certified-fully-modular-psu

Thanks, but actually, the Wednesday Jan 7 file system is what's already installed.  It came pre-installed in my two miners.  But thanks anyway !

PS.  I appreciate you trying to help people out on this thread and I'm sorry you are sometimes received poorly.  Your responses are necessarily conservative and it's a shame some individuals find that objectionable.  Best wishes!

That was fixed in the first firmware revision and was a known bug. You can download the latest S5 firmware here.

Have had two S5 running flawlessly for three weeks and today experienced an issue (batch four, OE file system, CGminer 4.9.0).  One of the two appeared to have frozen.  Perhaps half a day elapsed while both controller and Hash appeared stuck.  Discovered the problem by observing lower than expected Hash on Eligius and traced it back to the specific S5 by addressing it, whereupon it displayed the miner status page (without my logging in or requesting it), but was unresponsive to GUI selections.  Shut down the PSU for sixty seconds, fired it up again, and back to normal.  It now once again appears fine.

Thanks dogie and biodom!

I think I'm gonna get one of those nf-12. I need the miner a bit more quiet at a longer distance. I can hear it from in my kitchen which is down stairs and around the corner from my stairs and the miner is literally at the top of the stairs. I don't mind hearing it if I'm by my desk or walking up the stairs but not throughout the house. Thanks for letting me know that they are not quiet but from a distance they are not noticeable.

Dogie,

Thanks for the hardware error explaination. So a few hardware errors is almost expected when temps climb, but when hardware errors climb exponetionally, it's a problem. I've cranked the miner up to 300Mhz or about 1Th/s. Temps went up to 61 and 57. Within an hour I got 1 hardware error. It's been at this setting now for almost three hours and still at 1 hw. I like your range of 60-65c it's more realistic to real computing.

Another question...

How do you shut these miners down to say replace a fan or move the miner? Mine came with an antminer motherboard switch. Being a computer geek, I hate just cutting the power. Somehow it feels wrong, but is that what your supposed to do? Just kill the power either with the red antminer switch or the psu switch? Doing this a couple of time switching out fans to try them with temp control lead one board to not respond during initial boot. It was only after full boot and a restart that the board came back online. I can't find a shutdown or turn off setting anywhere, so how dose the rest of you power down your miner for either maintenence or changing a fan?

I can't directly answer your question, but I've tested closing top and bottom off. It moves temps ~1.5C, not record breaking, and that's SEALED top and bottom rather than more plates which won't seal.



I would have thought that you're losing more in GPU depreciation than you're mining, surely? What coin are you on?

208V will get you better energy efficiency out of your power supplies. You could run 4 EVGA 1300W per 30amp 208v breaker of a PDU. I would use a PDU like this one to distribute your power to the PSUs.

You would then need to buy new cables for your power supply that will plug into the PDU.

If I make the leap to grow my home operation I will certainly go with 208V.

Unfortunately, the only way Bitmain gave us to turn them off is to turn off the PSU. Yes, it does seem wrong and I hate doing it every time I need to. 

Has anyone published out the wattage draw to frequency settings in a chart for 110v?

Also...

I'm considering adding in additional S5s to some 2 Phase 208v 30 Amp Breakers. I have 4 of these circuits just sitting idle in one of my rooms.

Im a little unfamiliar with 208v to begin with, let alone 2 Phase. If I buy the simple distros for the sockets, use EVGA g2 1300w PSUs, how many could I plug in and feed of a 30a 208v 2 Phase?

Thanks!
