Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 75. (Read 451039 times)

I know KnC says they've rolled out their 16nm but KnC says a lot of things, some not true after their shipping delays and being sued over it.

Fact is, if they're producing 0.7w/gh gear, everything else will be obsolete, unless Bitmain also has 16/14nm taped out and ready in mass quantities.  I've just finished a deal for a space with cheap power in WA state, but at this point, I'm loathe to purchase any miners to put in the space.

TBH it worries me. It's hard to make investment plans when the mining landscape is like this. Buying 0.4-0.6w/gh gear when actors like KnC are pumping out sub 0.1w/gh gear is risky when the price is either flat or falling. If we get a 5x/10x BTC price jump, the sheer amount of gear and electricity needed to pump the hashrate, even to make S3s unprofitable, would make it much easier. But if we can't get next gen gear, the hashrate will catch up with us eventually. You'd think there'd be a market for bleeding edge gear for smaller or home miners, but the string of Bitcoin ASIC bankruptcies of late isn't encouraging.

That's a good point, I hadn't considered that really.

It just seems so weird that NO ONE has announced a product or even teased one.  I expected to hear something from the Austin meeting last month and nothing came out of it.

The noise we've heard earlier from TSMC and Global Foundries was that Bitcoin ASIC manufacturers are ideal for first runs of new production processes due to low price sensitivity and high tolerance for low yield. Samsung and Apple et al. have much tighter margins and prefer mature processes. But, as you say, there have been heavy delays. Plus, Bitcoin mining gear manufacturers are not in excellent shape nowadays.

Considering the heavy delays for 14/16nm production sites as well as the increased demand from large manufacturers (samsung, apple, et al) I really doubt we'll see anything in the 14/16 space this year actually released.

Thx! Not many producers left to buy from.

i pestered bitmain, they gave me the approximate date.
they said to keep an eye out for their 'official' announcement... 'paitiently'.

im not seeing any official announcements..

where do you get this s7 story?

Bitmain says s7 late july.

idk if this is 14 nm though....

i reckon Bitmain will always sell miners to anyone who buys them and pays the electric bill.
much easier profit for Bitmain that way.

Question to Bitmain, Dogie or whoever is in the know:

Will Bitmain sell their next gen 14/16nm Finfet machines or solely mine themselves? Any time frame?

While no amount of overclocking is safe, I personally wouldn't go above 72-740. You shouldn't really need to bump voltage to overclock though, you'll cap out the chips before any additional voltage will help.

overclocking c1... what voltage can i go up to before im redlining? where does it become unsafe?

this is what im trying to do. Im currently using teamviewer.I have new 13" macbook pro i leave on all day. it only uses less than 8.6watts idle with the screen off. I was just looking for a better solution. guess ill have to stick with this.

I personally would throw them behind a firewall/router.   You can use VPN/Teamviewer, etc to log into home network and change items as you want.

This way you don't have them out there for the world to see.

you guys are all miss understanding what he wants.. its not that he cant find the s5s on the network.

he wants to connect with them over the internet or something.. which is a bad idea..

i told him he should setup a vpn through windows and then he can access all the miners like he was at home.. but he ignored me.

Also if you have a decent router looking at connected devices can do wonders.  Part of it depends on how many items you have connected to network.

But if you look at device list normally you can start going to IP's and find it.

or this one unless that's the same one not sure .



yup same one !!! .

yours was a 5 pin fan, thats why..
yours is also only 1.6A


his is a 4pin PWM with Speed Sensor Inverter and also 4 AMPS per fan.. (i think he got the cheapest fans he can find as the afb fan is usually about 5-10$ more)

basically he has 2 issues.. well more then 2 issues since i have said this in 3 of his threads that he created..

issue 1, the s5 controller cant do 4 amps on the board.. when i plugged mine in the s5 woudlnt even turn on..

issue 2 is that fan as an inverted pwm controller.. you see normal fans have a pwm that uses 0v for full speed and 5v for off.. this is why when you cut the blue wire the fan goes full speed..
on this fan, it uses 0v for off and 5v for full speed..

this means that if you dont connect the blue wire to ~5v, the fan wont even turn on.

this is an issue on the s5 becuase when you first turn on the s5 it puts 0v to the pwm line, making the original fan turn on full speed while the unit is booting up.. but this fan wont appear to do anything at all. (since it wont boot up with 4 amp fans it probably wont ever do anything)
then when the s5 boots up, it lowers the volts down to whatever is needed temp wise. but since this fan is backwards, it will actually slow down as temps increase, eventually turning back off again as this fan wont run at under 2000 rpms or so.. so even if you hook the red and black wire to the black and yellow wires of a molex and then use the blue and yellow wires on this fan connected to the fan header it still wont work correctly

I use ipscan24.exe  (freeware from last year on this thread)
All s5 are on one network.

scans all ports for all devices.

Some people had to change the order of the wires to work proper.   

Mine are the Delta AFB1212SHE and worked with the standard wiring configuration.

I hope you can get yours to work.
