ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[MyRig]

fans for S1 and S3 has lower RPM and it is less noise... 

At what speeds are your fans running at 350mhz?
I am currently doing 4080rpm @ 56C with the stock S5 fan. Trying to find a decent exhaust fan to low temps for find an alternative cooling method.
Vertically standing i drop temp by 1C average.

I must say I have a new found respect for the S1 fan with its noise levels.

Can someone tell me where the cgminer.conf file is on these things? I'm going blind.....

It's in /config/cgminer.conf

Cheers

Ah! Of course - I couldn't see for looking.......

Thanks

And the S1 was ~350W rather than 600W. But still, S5 is a hell of a lot louder.

I've been doing some calculations and at the moment it seems that nobody is near ROI with this miner.

If you received it on Jan 1 2015, and you had FREE ELECTRICITY and you sold all your BTC during that price spike on Jan 25 2015, you would have made a profit of $165 till todays date.


But its rare that everybody sold on Jan 25th at ~310BTC/USD and rare that most have free electricity.

Taking the average price using moving averages of the last few weeks and average power rates you would have made only $60 to date with this miner. Why did they sell it at such a high price?

Because many people do have free or next to free power, and most people aren't looking for a 50 day ROI.

Have my two S5 up and running with overclocking stable so far. Both are connected to a CX750M PSU each.
Optimal overclocking settings (Frequency) has to be determined for each unit seperatly with try and error.

I have now one running at Freq 400 resulting in 1.3TH, the other one runs at Freq 393.75 resulting in 1.26TH.

What I figured out is, that you should look out for the HW error rate. As long as it's in the 0.0xxx% range, it's ok. As soon as the HW error rate reaches 0.xxx or higher, the Hash rate drops.
So in my case, when I set the Freq to 400 on my second S5, the Hash rate drops from 1.26 to 1.23 while the HW error rate climbs from e.g. 0.0376 to 0.2135.
And it gets worse the higher I set the Freq.
Of course you have to watch temperatures, which is in my case not a problem, running cool at 45/48 with Fan at 3240 rpm in ambient temp of 16C (loud yes, but in the basement so I don't care).

So my advice for overclocking: I would start with a Freq of 375, let it run for about an hour and monitor temp, hash rate and HW errors. If all is fine, go one step higher etc. until you see a drop in the hash rate along with the above explained HW error rate (or your temp goes through the roof).

Hope this helps.

6.25 less in frequency makes you win 30 GHS

I sold mine for more than I paid for them. They mined for about 30 days. So was paid to mine for 30 days minus the cost of electricity. I did ROI on the 3 S5's that I had. I had them all overclocked. Two of them averaged 1.34 th/s and the other was 1.36 th/s all of them at 412. Running free air style cooling in north Florida. I still have all of the BTC that I mined and converted the funds from selling the S5's to BTC when the price was about $210. I sold the miners because I'm moving and won't have any room for them at the new place.

Why did they sell it at such a high price?

the simple answer.... because they can. The market will bare it.

At this point there are really only 2 options for home miners... Bitmain and SP and Bitmain is less than SP.

Can buy C1 and S5. Just no more S3.

When I make the can switch I'm not going to be at 1.1Th/s but I would like to be close. I'll be watching the temps and if I'm stable and I can run the miner in the 60's then I could get a few more hashed out of it.

1) What power supply make and model are you running?
2) Are you seeing the varying hashrate on the S5's status page or your pool's status page?
3) What pool is it at?
4) Please can you provide a screenshot of the S5's status page?

Temps are best kept under 60C but its not a "its going to blow up" situation if below 70C. You may shorten the lifetime of your S5 by running it that hot however. Hardware errors shouldn't change appreciably between 60 or 70C either.

I am using a EVGA SuperNOVA 650G1 650W ATX12V Power Supply 120-G1-0650-XR power supply
I am seeing varying hash rates on both the status page and the pool's page. I know they are not going to be exact but the pool shows a dip in my hash rate, the hash rate graph on slush's pool (the one I'm using) looks like a saw blade rather than a straight line. The miner is set a 337.5 and that should give me 1.1Th/s but it sometimes dips to just under 1Th/s then back up.
Im using slush's pool with btcguild as a secondary

sorry, its been a while... how do i post a screenshot? i have it in png format

That is normal.

Because many people do have free or next to free power, and most people aren't looking for a 50 day ROI.

I've been wondering about free or low cost power.  I've  been to trying research and figure out how to find exactly that for a few weeks now, but to no avail.  No one I know has unlimited power included in their homeowners or something similar.

I'd love to hear some solid advice on how to join these many people with an edge on power costs.

Thanks.

Its just for the holidays, everything proper shuts down at this time.

Europe requires a hell of a lot of heating, which is elec/gas that would have otherwise been burnt for free.

Does anyone use a dust filter on their s5? I have one on the push fan. It contributes a bit to the noise but what do you all do with dust?

[MyRig]

Hummmm  interesting question...

we have not seen a masked S5 yet 

any pictures?

The Avalon 4.1s are nice for home miners as well.  Just a bit more expensive, but extremely quiet for 1+ TH/s.   I have a mixture of Bitmain S3s, S5s, and Avalon 4.1s.

I originally had 9 S3s at my office, but have since brought them home and replaced them with the Avalon 4.1s since they are much quieter and virtually have almost no sound at all since noise is the concern at the office.

Who's the North American supplier for Avalon 4.1?
