Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 190. (Read 451039 times)

I have ordered my first S5. Got to see how mining works with them. I have been mining with GPUs now for over a year.

Do you think it is more profitable to switch from GPU mining to ASIC mining via Antminer S5 for example? I don't have to pay for electricity anyways.
Therefore I could sell my GPUs (6x R9 280x and 3x r9 290) and switch them for ASICs. But lately GPU mining is dieing so hard. It was fun early, when coinlaunches were made. But there are so less coinlaunches in last time because of all the scams. The cards have been running on Nicehash since over 2-3 months now.

I pay for power out of pocket and keep the btc. Just consider it as buying btc from your power provider. 

Hi all,

So I'm a little new to mining btc with a ASIC miner. I just got my s5 the other day and I have scowered the Internet looking for ways to get the most hashing out of it with a quieter fan. All that aside I think I'm gonna use a noctura nf-f12. Right now I have a sonon 100cfm fan that is not as loud as the stock fan but it is still a bit loud. I also have a second fan pulling at 1350rpm 74cfm.
My temps are 55 and 58 at 275Mhz with 2 hardware errors over a 12 hour period. It hashes at about 900gh/s. I've not been able to get the miner to stock settings with other fans like everyone else on the forum without going into the 60c range which I read is da get zone.

Maybe it's my setup, it's out in the open on its side sitting on my desk. When do hardware errors become a concern? Why is it not recommended that the s5 not be allowed to enter the 60c range when over heating is set at 80?

Also, i love the s5 but I'm afraid of my energy bill. How do you guys pay for energy? Do you convert btc to currency and pay that way or just out of pocket and keep the btc mined?

Thanks, sorry if these are n00b questions and belong in a n00b section but they are about the s5

Ok You are right. I didn't want to send plastic to landfill and used the protecting foam as hashing stand and resonance absorber.
After starting I realized that resonance was ny smallest problem.

 

 

rent them out on westhash.com or nicehash.com for example.  For example during the whole paycoin scam..eh I mean hype the rates were up to like 0.05 btc per th and even higher....so in 3 days i got like 0.15btc for 1 s3+.  considering i paid 0.525 or something, (+stupid ups fees/taxes)

Unless the S5s are placed on a solid flat surface in the standard orientation as designed by Bitmain, the bottom would have to be closed up as well (the S3s are).  Otherwise, in any other orientation (on its side, vertical, etc.) or in standard orientation on wire shelving units, the bottom would effectively become an opening, thereby defeating the purpose of covering up the top (only).

Not entirely disposable and obsolete.  Some people in here claim that they make some profit or at least break even or recoup some of the capital at a loss by selling off these used up miners.  There's obviously a market for it and so it would make sense that having a better case would also have a better resale value.  Also, 6-9 months of ownership of these units is a long time to be subjected to high noise levels and to be dealing with less efficient cooling by employing an open-case design as opposed to a closed system like in the S3s.

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.

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.
