AntMiner S4+ available for global sales on April 20th, shipping within one week

[MyRig]

1 thing for this S4+ is, it is a new PSU different from the previous S4 version.  It is stable on 208v.

if you like the rack mount system, you will definitely like this unit. 

Also, not like S4, this unit does not require human interaction with the switch on the back during the power cycle.  When the power comes on, it will boots right up!

Just had a negative growth and it may be another negative growth in about 12 days YAY!!!

Bitmain,

I assume air intake is on the front of the unit, where you plug the PSU? Is it OK to reverse the airflow by switching all 4 fans around? I need the front to be the exhaust side.

[MyRig]

Air intake is from the front (PSU/Ethernet port side)  THere are 4 fan connectors on the control PCB! 

Always the policy is any modification of the unit will void the warranty...

side note, reversing the fans should not do any damage.  2 fans to intake and 2 fans to suck them out of the box.

I was hoping it wouldn't void the warranty since it's such a minor thing. Bitmain had us switching PSUs and fans constantly with the S4, even hash board occasionally. Surely just reversing the fans should be allowable without voiding the warranty?

I could be missing something but why not just turn entire unit around, instead of reversing fans?

He needs the power plug  to be in a certain position.  I am assuming that all other power plugs on all his gear  are the  outake side.

Yeah, that's the more logical thing to do. With the S4s I reversed the fans so I could still see the LCD screen, but there's no screen this time around.

In my case it's mostly about having airflow where it needs to go while still having access to the front of the units. This pic will give you an idea with some of the rigs:



Wouldn't want all that hot air stagnating in back of them, exhaust needs to come out of the front where it's then extracted via a large fan to the exterior.

I really like your setup.  After rereading my suggestion I just want to say I did not mean as an insult.   It possibly could have been taken badly.  I was meant as a suggestion not insult.

Thanks That's in my detached garage at home, which only has 60A to work with. What's in that picture is taking it all up, so I still have a lot of hardware in the house that needs to be moved out there once my dedicated 200A electrical entrance is installed hopefully in the next 2 weeks or so. Hardware not pictured: 2X Neptunes, a Titan, a 90MH A2 Terminator, 2x S4 and as of Thursday 2x S4+.

I didn't see it as insulting at all, it would be the most logical thing to do really... I just like complicating my life for nothing, so I reversed the fans in the S4s and the Alcheminer to suit my "needs".

And just think, after Thursday you can stop complaining about those "noisy SP20's", since the new S4+ will completely drown them out! 

I am glad I don't get your electric bill each month. What's your electricity cost if you don't mind the inquiry?

Heh, I run the SP20s at 100% fan and don't hear them thanks to the 2880w PSUs. they're pretty much all I hear, in fact. Doubt the S4+ will be louder than they are!

I pay about 7c/kWh USD. In Canadian funny money, that's $0.086.

[dogie]

I've got an S4+ sitting next to an S4, identical fans and identical noise. The PSU fan isn't a factor. So the S4+ is loud but its nothing we haven't experienced before.

@bitmain

Can you tell me about the Capacitors on this?  I am looking at cheating and moving your product to a full immersion mineral oil bath.

The only issues I've ever had with Mineral oil cooling is when cheap Capacitors are used, and they plastic swells and bursts from the mineral oil.

I'll have some 6K pictures either today or tomorrow of internals.

Thank you!

About 1/3rd of the pictures are processed No caps anywhere on the hashing board and none that I could see on the controller either. Cables on the non PCI-E version of the PSU are very long so this should be good to dunk.

Only just got my unit started on the testing rack so a full review will be some time, but surprised with the noise. I thought the 40mm PSU fan was going to be an issue but its inaudible over the main fans. That means noise levels appear identical to the S4 above 25C, and slightly louder above as it runs hotter.

No Fans no noise.....

This is a no brainer... This is what the s4 should have been...

To release this now with old chips, Shame on u bitmain.. Seems like u have excess stock in your warehouse of maybe C1's and ur trying to get rid of the chips in bulk..

To high a price with S5's in circulation, To high Wattage, To much noise.

I was looking forward to an S4+ using the newer S5 chip at least at 1500w at least that would have pushed it over the 3th mark..

Bad rushed decisions... Come on bitmain, U were the best at this & now your slowly starting to run downhill at a very quick pace & u still havent fixed the voltage settings on the S4

Heres a tip for the S4 in the Freq table take out all the over clock settings & lock them down but leave the underclock settings..

Then in the voltage settings put a drop down box with the underclock voltage settings with suggested freq settings so that people cant blow these things up.. But can downclock them.

Then also put a box allowing the  --bitmain-homemode or normal mode so that can be run a little quieter.

Sometimes for the miner, the best strategy is to run the miners that already in hands and not to buy any new miners. Only buy the miners that is best for you. For a home miner the electricity cost is high and noise is a pain, so we should buy the high efficiency mining rigs. But for large scale miners, the cost of electricity maybe low and noise level is not a concern, they may have better tolerence with the old chips and not so sexy power efficiency.

Was the above meant for me?? The S4+ is no good for no one...

Why use old chips when new one are available that are faster & more efficient??

Leftover old stock by the sounds & if this is the case they should have sold all of them before releasing new ones.. This is bad business practice that smacks of greed!

So I just convinced my Wife  to sell our home in NJ and move out to the state of WASHINGTON.
We are both retired have pensions. I found a 15 acre place with a barn that had a large 200amp 240 watt service in it since the prior owner had a welding business.

 Power is 4 cents.  200 amp 240 means 48kwatts x 80% = 38 kwatts,

 I can fit 25 of these . they would be far easier to  manage then s-5's the bold is how they could work for me if the example was true.

So basically these are for low power cost farms and data centers.  Not no one. As you think.

But I agree with one thing they are forcing a guy like me out of the game Since I do not have the ability to keep the noise controlled.

[Dr Charles]

Whoa!!!


Just about time that a manufacture released a new product.


This miner is going to be BIG!

Since this uses the same chips as the S3. Can the S3 be downclocked to run at a similar efficiency? 0.58J/GH ?


Also I think this should be put in bold

1. The included PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.


Pretty much has no market in North America then.

Exactly, pretty huge shot in the foot.

Would a step-up transformer work to power one of these units from a standard 120V connection?

Something like this:
