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?

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.

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.

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

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. Sad

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

I think I found my limit. I have an s5 running 337.5 with only 4 hw for 24hr period. It's hashing at 1.1Th/s but sometimes it dips to just under 1Th/s. Why is that? Is it due to power irregularity? Also, at these settings to he temps are 66 and 68. I know that is high for the miner but I'm not getting hw errors. So I think this is stable. But the temps. I keep reading that the miner needs to be below 60. Is that due to instability and hardware errors. I once thought heat was related to hardware errors but with this discovery it is inconclusive. So, all you really knowledgeable people out there, is is safe to rum at or below 68c? I have a push pull fan system and have replaced the stock fan. It's not quiet, in fact, I have to make another fan changeout before the week is over. This fan setup is too loud for the fam.

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.

What is the idea around the static blades on the S5 fan?
I read that it should direct the air flow to some extent. These blades have a twisting effect.
I am trying to drop the dbs of the fan with an extra pull fan, but to no avail. S5 fan does not drop below 3680 RPM.
Deta fans and Silverstone fans will take 6-8 weeks to reach me.

You'll get different answers on this but one of the simpler ones is it increases static pressure per W.

What is the ambient temp? Usually target temps/manufacturer ratings are provided at ambient temps if 18 to 20c. My S3 miner is designed to run at 30 odd degrees. Thanks to summer, it runs at around 47.

Ambient temps are about 71F. Not sure the c conversion. It's not summer where I am but it's not super cold and the floor where the miner is never dips below 71F and sometimes it goes to 76F but not lately. Another complaint from the fam, upstairs is too warm. But now that is 71F I think it will be just fine. We like to live around 72F anyways.

My S5 lost half its hashrate today. Its been about 8 hrs of reduced cycle. This is my first bitcoin miner. How should I approach troubleshooting?

Switch the power supply off. Count to 20. Switch it on.

If this doesn't help you might want to try another PSU, try powering one blade at a time, swap controller cables, swap controller ports.

It`s not a PSU issue, i have 2 s5 on 2 different PSU A 750w and a 1000W, and yes they drop to half speed alot ramdomly, ( NOT OC`ed ), sometime after 10-20 mins they will go back up to full speed, sometime not, and sometime totally freeze up and need a PSU reset.

i would have to assume it`s a firmware bug

It's odd. I went from Nicehash and rebooting every few hours to ghash and once a day reboots to f2pool and 9 days uptime straight. Could be pool related.

s5 has issues apparently when mining low difficulty coins, so on nicehash it can cause problems

Hope this helps.

Do you monitor power consumption? What differences have you noticed? Would just like to see if overclocking is consistent across the board between units or if each unit operates at a great difference.

Sorry, not at the moment, as I am currently only after maximizing overall Hash Rate. But will do shortly, as I have to move around some PSU's because I'm expecting a couple of SP20's to be added to the HW zoo. Will post when I have some figures, probably in 1 to 2 weeks.
