ANTMINER S4 Discussion and Support Thread

[dmwardjr]

Thanks again for helping out.

I couldn't resist!  If my posting this offends members, I'll take it down shortly.

Just wanted to show y'all what I was up to with my data/mining closet:

As you can see, there is still some work to do.  Still waiting on several 240V/30AMP outlets to get here from California [Ordered from Amazon].  This means I'm pulling out 5 of the 7 12/2 wiring to replace with 10 AWG for the new 240V/30AMP outlets.

You see six (6) different colors of SF Cable, 6ft IEC C14 to C13 Power Extension Cord 10Amp 250V 18/3 AWG SJT.  

They will be used to plug into two (2) Tripp Lite PDUMV30HV PDU Metered 208V / 240V 30A 6 C19 24; C13 L6-30P Vertical 0URM's.  One of them is to the right [Out of the box] and one is on the left [Still in the box].

The bottom shelf and the shelf above it will have to me removed temporarily to install the Tripp Lite PDU's on the back wall.  The shelves will be repositioned [When re-installed] to allow enough space between the shelves to be able to turn S4's onto their sides to help me place more S4's in this closet than previously intended [25 S4's instead of 20].  [If y'all think they should not be positioned onto their sides, please let me know and why?]

There is a 14 inch Can Fan Max with 1820 Cubic Feet per Minute (CFM) of suction for this 122 cubic feet closet.  You also see a 16 inch return near the ceiling in the back where the 14 inch Can Fan Max is connected feeding into the garage.  [Working on duct work to feed the hot air to the outside from the garage.]  This is a youtube video on the 14 inch Can Fan Max:  https://www.youtube.com/watch?v=4DxbWXo4dF4

You also see an 8000 BTU Air Conditioner installed in the back wall coming from the garage.  It is quiet and a helpful addition to keep this closet cool.  You will also notice a 16" x 25" filtered grill in the closet door in the second picture.  This allows the 14 inch Can Fan Max to pull in TONS of cool air from the recreation room downstairs.  

A window is open just to the right of that closet door in the recreation room to allow the fan in the closet to suck cool air into the closet.  Enough air is sucked into this closet that it will blow your shirt over your head if you were standing in the closet without your shirt tucked into your pants.

Hollow square metal rods will replace the wood bracing I have underneath the shelves I have soon.  All wiring will be neater as well once the PDU's are installed and shelves are re-installed after proper spacing.

A little bit of history with more photos [even of what is going on behind the closet wall in the garage] of what I've been doing through trial and error can be found here:  https://bitcointalk.org/index.php?topic=766998.40



I'm remodeling my recreation room.  So, don't mind the base molding that has yet to be nailed on, primed and painted.

re: the metal bracing, I'm just wondering whether you ought to consider fitting a central vertical support pillar on those shelves as well (from top one down to floor)?  Also, is there any way that you could duct all that hot exhaust air around the building, instead of just into the garage?  It would save on your heating bills in the winter and you could have a by-pass duct straight to the outside air for use in the summer (no need to run the aircon unit then).  I appreciate that it's easier said than done and ducts aren't the nicest things to look at in living-rooms (perhaps you have ceiling and wall voids to hide them in), but it seems such a waste of valuable heat.

that top shelve....

[dmwardjr]

Apologize for getting back to the forum late.  Had very little sleep the last few days.  It caught up to me.  Fell to sleep approximately at midnight instead of the normal 2am to 3am that it has been.  So, it was good to get some sleep.

I don't want to fill up the forum space with too much talk of this project out of respect to others.  More pictures with descriptions of this as it progresses will be posted on "Miner Porn Photos" at https://bitcointalk.org/index.php?topic=766998.60

re: the metal bracing, I'm just wondering whether you ought to consider fitting a central vertical support pillar on those shelves as well (from top one down to floor)?

It's a consideration.  After the horizontal support is completed we'll have a look at how it works and see.  Here is the perforated steel 1-1/2" x 1-1/2" x 72" on the menu for horizontal support:  http://www.amazon.com/Steelworks-Boltmaster-11205-2x72-Tele/dp/B000BD5F7O/ref=sr_1_fkmr0_2?ie=UTF8&qid=1416060848&sr=8-2-fkmr0&keywords=H+Plated+Steel+Perforated+Square+Tube  It would be cut to 43.5 inches to fit horizontally.  Two (2) of these 43.5 inch perforated square tubes for each shelf.  The same can be used for vertical support if needed because it is 6 feet long.  Prime and paint them white before installation.  

There are two (2) 1"x 2" wood braces installed horizontally under each shelf at the moment except for the bottom shelf.  They aren't doing too bad, considering the weight on them right now.

Also, is there any way that you could duct all that hot exhaust air around the building, instead of just into the garage?  It would save on your heating bills in the winter and you could have a by-pass duct straight to the outside air for use in the summer (no need to run the aircon unit then).

That's exactly what Will be done soon.  I have all kinds of 14 inch duct (90 degree elbows, two (2) Speedi-Products FD-25R8-14 14-Inch Diameter by 25-Feet Length R8 Insulated Flexible Duct with Metalized Jacket, 26 gauge 14" in diameter "T" duct (one to tie into the existing duct and the other to feed outside through an exit duct with damper).  All of this purchased through Amazon.  Really don't mind the heat going into the garage at the moment.  It seeps through the floors up into the house at the moment [Keeping out the wood flooring toasty to the feet in the bedrooms over the garage].

I appreciate that it's easier said than done and ducts aren't the nicest things to look at in living-rooms (perhaps you have ceiling and wall voids to hide them in), but it seems such a waste of valuable heat.

Actually the duct work would be above our head in the garage tied into the existing duct work that feeds all the vents in the house.  It will be a lot easier than one might think.  The duct work is already visible in the garage to the eyes.  So it doesn't matter to me if it's seen or not.  No duct work will be visible in the house.  Using existing duct work to feed the heat to the house.

that top shelve....

Not sure if you were referring to the top shelf drooping a bit or if you were asking what is on the top shelf?

I'm going to keep the top shelf rather empty [no mining rigs] to allow for air to pass through un-incumbered to the exhaust fan.

The top shelf has a TP-Link TL-SG1048 Switch with 48 ports.  The 48-Port Gigabit Switch is designed to meet the needs of the most demanding workgroup and departmental connectivity requirements. A reliable, easy-to-use switch without the complexity of management, it provides 48 10/100/1000Mbps ports. It combines ease of use with unsurpassed performance resulting in an exceptional value for any cost-conscious network administrator who wants the best possible solution at the best possible price.

An Apple Airport Extreme Base Station is to the far left on the top shelf.  A big black cable modem for my telecommunications training business is also on the top shelf.

Here is the perforated steel 1-1/2" x 1-1/2" x 72" on the menu for horizontal support: http://www.amazon.com/Steelworks-Boltmaster-11205-2x72-Tele/dp/B000BD5F7O/ref=sr_1_fkmr0_2?ie=UTF8&qid=1416060848&sr=8-2-fkmr0&keywords=H+Plated+Steel+Perforated+Square+Tube  It would be cut to 43.5 inches to fit horizontally.  Two (2) of these 43.5 inch perforated square tubes for each shelf.  The same can be used for vertical support if needed because it is 6 feet long.  Prime and paint them white before installation.

The temps on these S4's run a bit warmer than S3's.  My S3's temps per card range from 36 to 40.  The temps on each card in this S4 are as follows:  44, 43, 47, 46.  I wonder if someday replacing the existing fans with other faster fans would help?

A question from the Newbie for those of you with experience:  What temps do I want to try to avoid reaching in this S4, especially on a consistent basis?

No temperature is even close to 'we actually care' levels. <55C is fine.

WOW, these rigs can maintain operation with a lot of heat.

I was thinking about the longevity of equipment and the affected hash rate of the equipment.  I should have been more specific.  I've seen pics on youtube of rigs laying in a pile on the ground at large farms in China that I assumed had went out of service.  The building they were in appeared to be poorly cooled with large doors open to the outside.  So, I assumed the rigs would burn out much sooner than normal with the temperature too high for long periods of time.

Curious if anyone has had enough experience with S1 rigs since they came out to know if the temp mattered that much.  It used to be that S1's were the rig to have.  It may be that not enough time has elapsed to even know the answer to my speculation regarding the S1 even.  Don't know...

Thank you for your input!

Anyone else want to ring in?

 "longevity of equipment and the affected hash rate of the equipment."

In 8 to 9 months there is a good chance your equipment will be cash-flow negative due to difficulty and cost of electricity … The life cycle of mining is VERY short ...

Hi there,

I have a defect fan on my S4. Do you know where on the web I'd find a compatible one, same specs?

In the meantime, my S4 won't start mining because it detects a 0-RPM fan. I tried giving it a manual spin and the S4 started hashing. Do you know how I can tell the S4 to mine even if there's a missing fan, without giving it a spin?

I sent an e-mail to Bitmain but thought it would be faster to get one if I order on the web with priority post or something like that. I'm in Canada.

Thanks!

I got the fan specs from bitmain sometime back as I wanted to look for quieter fans. These are the specs. http://prntscr.com/56s4gz

First - I found 9 coupons for S4 under my account, but 0 for C1 - it looks strange. 
Second - please let me use all that 9 coupons at a time! At least 3 of them!

You know it's never going to happen. Lol. And I bet the moment the coupon expires, S5 will magically appear for sale....

[Rabinovitch]

Looks so. And it will appearantly be not-so-expensive (keepeng in mind the amount of the discount for S4)...

[Prelude]

Hmmm... To order more S4s, or not.. Coupons are making my trigger finger itchy, but then... S5..

With existing duct work, it's going to make it so much easier.  A real opportunity to get even more payback.

[Prelude]

Gotta love natural Canadian cooling.  



And it isn't even winter yet. If you're wondering, temps are showing 0 because S4's temp sensors don't register below 20c.

[Namdher]

hello, do you try? because i have the same problem and i dont know to solve this problem.
