That is very helpful.  I did not realize that about Nicehash.  Thank you!

They are a few options you can do, most of them "today" are not worth the hasle but most of the time, they are good and you just point your miners to the better one.

1 - Nicehash.com ( they pay you for your hash in BTC, usually better than mining straight bitcoin )
2 - LeaseArig ( you rent your rig to people )
3 - betarigs ( same as above )
4 - miningrigrental ( same as above )
5 - multipool.us (profit switching pool )
6 - and of course mining new coins at release and trading them went they hit the market ( If they do, its a gamble but pays best most of the time )

The easies is Nicehash put a password of (p=0.01225)
this is the current payout for mining bitcoins today, so if nicehash pays above, you`ll mine there, if under it will default to you second pool and mine bitcoins at your pool choice.

Hope it help and Happy Mining.

I just got my S5 hooked up today. I'm currently running 1 S5 on a 1300W EVGA Gold and will be adding a second. I replaced the stock fan with a Delta Electronics AFC1212DE-SP02 (Dell P/N Y4574) 120mmx120mmx38mm Cooling Fan, 148.34 CFM, 51dBA, 3900 RPM, 1.60 AMP, Dell 5-pin 4-wire Connector, which I bought on Amazon for $25 after shipping. So far I'm very impressed and my board temps are at 55/51 while running at room temperature in my office. I hooked the fan up using a molex adapter which is pulling power directly from the PSU.

For the noise level I went from 75 db stock fan to only 59 db with the Delta fan.

Using a kill-a-watt meter it is pulling 587 Watts at the wall while running at the factory 350MHZ speed and hashing at 1155GHs. That equates to a 0.508 W/GH ratio which is right on spec. I also suspect that running the smaller fan is probably saving me a few watts too.

I have 2 SP20 miners running at the same hash rate underclocked and they are getting about a 0.54 W/GH ratio, so for the same watts/hash rate the S5 is winning that battle. What I can't get over, as other are stating, is why is there no top or bottom? The cheap plastic sides are bad enough. Why couldn't you provide a plastic top and bottom. I can feel alot of air escaping the top and I'm forced to place these on a flat surface so air doesn't escape the bottom as well, where for the SP20's I can stack several of them. Not to mention I don't have to alter the SP20's fan or design. It's truely plug and play.

Could you point me to a thread with tips on what can be done to manage miners to achieve a better ROI?  Or would you please start one?

if you know how to manage your miners, you can ROI, i bought some s3 and they ROI'ed in 2.5 months including electricity, but if you just point them at a bitcoin pool and forget about them ya, you might never ROI

I'm moving the discussion quoted above on Bitmain's warranty policy here since it was getting off-topic as per the OP, but I think it warrants some more discussion. I also had my own comment, which is that Bitmain should make its warranty clear and conspicuous. Some people may be misled by the fact that Bitmain advertises the overclock potential of its miners when overclocking voids the warranty. I don't think something should be advertised as a feature if it also voids the warranty, unless that fact is made clear to the buyer. Just my two cents.

Another question on the warranty - any warranty issue will obviously cause some downtime, which is a loss to the buyer. Does Bitmain allocate an equivalent amount of hashing power from its cloud mining service during the downtime? 

Still going.

still i don`t get   ...
 ROI is "never" ?? What is the point of purcasing S5...

i have 50pcs of S1 turned off for few months allready..and they are useless 

"Case" could have been made from one sheet of the same plastic which is used now, holes cut for cables at top and U-shaped square "case" covering sides and top.  Every cheap plastic thing is stamped "Made in China" so I think it can't be very hard to find producer for this "case". 

this becomes less true with each generation as the watt to gh improvements are not as good


s-1 to s-3 to s-5

2 watts     .8 watts      .5 watts


I am leaving out btc price as a factor

Well do keep in mind the miners are disposable. They will be fully obsolete in less than 6-9 months time. So build to junk them. No need for expensive cases.

Strato

I hear you.  It's called "cutting corners to improve profit margin"...but people still buy them in spite of this inadequacy and so it is.  I think the S3 is the best one they ever made for this reason.

I have used my S5s now for about 9 days, I like the lightweight design but I don't understand why top isn't covered.
One piece plastic cover over the top and sides would have been very easy to make.

Noise is terrible, If so much fan speed is needed top should have cover also. Before I covered top with ESD plastic and duct tape I could easily feel air flow 1m over the miner.  Very hard to built efficienf cooling for many rack mounted miners if air flows almost every directions.

I installed S1 fan pulling to one miner, original fan speed is 3960 and S1 3480, temps 56 and 50 1320GH/s.

One fan miner 3960 rpm, 54 and 49 temps 1312GH/s.

STD air flow seems to be enought, I use DPS-600 server powers.

 

...and you're giving us only diagrams?  We don't need no stinking drawings.  We want to see actual pron pictures/photos.  

Anyway, these were my pron offerings wherein the miners are doing the PSUs dogie style:

EVGA Supernova 850 B2 Power Supply 80PLUS Bronze Certified 850W is the PSU.

Please can you try and take a screenshot of the S5's status page when you're getting degraded performance? What firmware version are you on - it should look like a date.

Not necessarily, being 80%+ efficiency doesn't guarantee its suitability for bitcoin / S5 mining. Please try and find the exact model, as its the first point of debugging for your problems.

Hi,

I too had similar experience as quoted, however mine did not restart every 7 mins. When I first got my S5, it was working flawlessly for good 2 days. Then the hashing rate would gradually drop and eventually to 0 and restart. Its left at default freq of 350, temp was around 54 in the mornings and 56 highest during the day. Its powered by a CoolerMaster v1000 PSU which is running cool all day.

I turned it off for 5 mins and started again but after running around 30 mins or so it will happen again. I have another 2 units of C1 running 24/7 which does not seems to have any problem, so I guess that rules out the internet connection possibility. I inspected the blades but could not find any burned or damages. The time it takes to enter the reboot cycle is not consistant, at times it happens in a few minutes or sometimes a few hours. I got my S5 via the DHGATE link at Bitmain's site together with a friend and he too has the same problem. Currently to get stability, we ran the freq at 300 and 325 respectively.

Any ideas?

Thanks.

I can't remember the brand but It's 850W Bronze. That should be more than enough right?

As others have said, nothing wrong with the temp delta between the two boards, its quite common and a product of a not very accurate measurement system. It does what it needs to though. What power supply are you using, the controller rebooting rather than blades dropping or X'ing is rather uncommon.
