Is there an S6 Coming out or a S5 upgrade like what they did with the S1 ?

The S5 looks like it can take two more hash boards hmmmm, I see something coming.

It's time to make an upgrade kits for AntMiner S2 with these new chips... U3 is useless product IMHO.

+1 The S2 upgrade got scrapped last time around because BitMain said S2 was still profitable. With current Difficulty and BitCoin price, not so much anymore. Would love to see an upgrade kit even if it only filled half the slots but at least provided positive income.

It seems 450 is the highest I can go, before performance starts degrading.
At 462 it dropped at 1300GH/s

How many watts are you pulling at 437.5 and 450?

I'm hoping for a S6... but from what I can remember... they send the boards out to have waterblocks made for them.. so I guess we'll see the C2 first.

S1/S3 to S5 or C2 looks to be an easy root but with the cost of a new controller?

maybe S5 will migrate to C3 format in 3 months time? (4 boards with BM1386 chips)

A 4 board S5 would need a power station of its own!

Does anyone use 2fan for cooling?

Planning to put on two 1500rpm fans to keep quite this thing.

dont waste of money

two of these are the best.

my tests with them

https://bitcointalksearch.org/topic/m.10158497

you can go low with 5.5 volts to the fans --------------freq 300 990 gh very quiet

or high with 9.2 volts to the fans-------------------------freq 393 1292 gh 10 db less then the stock fan.

I'm still stuck with the S4....

Bitmain, can we have the S6 with the same design as S4? 4 Hashing boards with PSU. And since the new board is using less power draw, the current PSU in the S4 should be good to go yes? Oh... and fans that can run full RPM 24/7 for us living near or at the equator ie. Singapore....

The Fans in my S4s are dying.. 1 by 1.. Another 2 died today... 4 down so far.. Sad

note sure if it has been mentioned for antminers
But, schedueled performance profiles.
In some countries power is cheaper during the night, so a profile that lets you run at one freq during the day, and a different freq during the night - or just in certain timeframes.
Would be very nice.

look into the cron/crontab settings. Its not the most noob0-friendly way to do what you want, but it allows you to setup the system to alter files at set times or intervals. I used it ton an antminer S1 where it had two scheduled tasks:

@10am: save asic-freq as asic-freq-night, rename asic-freq-day to asic-freq, restart the mining process
@5pm: save asic-freq as asic-freq-day, rename asic-freq-night to asic-freq, restart the mining process

asic-freq-night was set to a higher frequency (say 400Mhz) while asic-freq-day was a lower speed (325Mhz).

@437.5mhz

Wow!
Guys, I see many of you are overclocking your S5s already. Won't this void your warranty?
If not, I'd like to OC mine too. -13 C here... so i can likely get results like mitak64.

honestly, overclocking shouldnt break the unit unless you really push it too far and mess it up. It might wreck your warrenty, but most warranty claims for bitmain products relate to DOA or faults that occur within the first 24hrs. an antminer than lives past the first 48hrs of operation should be able to survive for most of its 12month lifespan as long as temperatures stay below 65C averages

try the OC - 437.5MHz is quite extraordinary, but you can likely get 412.5MHz (1.32TH) or maybe 425Mhz

Thx. I think mitak64 is right: "To me it sounds like Bitmain is encouraging us"

1.415TH @437.5mhz Grin

Im amazed you could push it that far - I put my B1 test unoit up against a window drawing in -7C air and it seemed to max out around 1.32TH/412.5MHz. Going to 425MHz knocked hashrate down to around 1.25TH without much increase in the HW error rate.
