Problem is even with the coupon they are way too expensive.

I calculate that you need both $950 price and $587 BTC ($200 higher) to reach breakeven in ~4 mo.
We urgently need 50% difficulty fall like in 2011; the cycle could continue at that point, otherwise almost all home-based miners will NOT order latest and greatest equipment above $500.
However, as ckolivas had noted, home-based miners are just 15% of the network, so nobody would really care if home-based miners would become 5-10% or even less.

Can someone please tell me how to remove the psu from the casing ? I have removed the rear screws but don't see how to take it out as it seems firmly latched to it.

Want to get my s4 ready when the psu comes.

Remove 4 silver screws…. open S4 unit from top 4 black screws on top… disconnect the 5 PCIe power connectors, 4 from hash boards and 1 from control board.. Slide PSU out from back of unit…

That should do it

Oh cool guess I didn't slide it out hard enough

Mee to have this. Nobody need it. And Bitmain refused to allow me to use this discount for buy S3 or whatever else. Only S4. It's sucks...

Here's another binary for S4 owners
http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer

This one works a heck of a lot better on pools that wouldn't work previously, and slightly better on the rest.

Is this an SSH one or firmware? I'm guessing ssh into the S4 and replace this file, but I'll let you tell me for sure.

Thanks.

Binary for installation via ssh only. I don't do firmware.

And a damn fine job you did with this for the s4! Both units now humming along perfectly on EMC pool Cheesy

Hiya,

Anyone know the Ideal Difficulty setting for the S4 on Slush's pool?

Why hasn't bitmain replied to my e-mail when other people are already receiving their replacement PSUs?

I replied to bitmain (shao) on the 15th Oct regarding the replacement psu.
Today they (shao) emailed me saying he is still waiting for my email regarding the replacement psu.

I took some screenshots of my sent email, and emailed them once again.

Maybe they did not receive your original reply to their email.

I can confirm this.

Take a look at this hash graph with the new binary on a Batch 1 Antminer S4 (not yet replaced PSU).

Thanks ckolivas!

So I was bored and did a little math on my current btc situation regarding the S4:

Bitcoins on hand    13.34
Avg Cost    242.57
Basis    3,236.61

Estimated Current Price    385.00
Total Current Value    5,137.06

Gain if sold    1,900.44


Antminer S4 Cost    1,250.00
Less Coupon    (200.00)
    1,050.00

Bitcoins at current value    2.73

Basis of S4 Unit    661.55


Estimated BTC Earned 7 months   3.357298701

At Estimated Current Price    1,292.56

Gain on 1 unit    631.01

# of units on hand btc could buy    4.89

Profit of units    3,087.15

This seems to make good sense until you factor in shipping. Once that's done, it's practically the same gain as selling coins. Not only that, but a 7 month horizon is probably too long a time for bitcoin risk. Oh well, just thought I'd share.

What is up with the new PSU ship date … I still have a miner down and almost past the point where 10 days mining compensation would not help me … Just trying to get a time frame on when we will get our credit and our PSU … Please tell me that our 10 day mining credit will not come in the form of coupons…

Don't know specific dates but they're being actively shipped. The credit [as I was last told] will be in btc.

Trying to figure out how 1028 s3 coupons will be of any value to me Sad

Also is there a way to tell if my incoming Batch 2s are the old PSUs or the new ones? Or do I have to open it up?

I opened up the first layer of casing but am not sure how to disassemble the PSU further. Any help?

All new units should ship with the new PSU's. But yes, to confirm you'd need to open it up and look for the bardcode on the outside of the PSU. The old power supplies did not have a barcode, the new ones do. At least that's what Dogie said, a page back or two...

This. New PSUs have a barcode.

Thank you so much for the time you've invested to make the S4 more funtional, ckolivas. I'm going to send you a donation tomorrow morning.

I'd like to try ck's new version tomorrow, but I have no idea how to go about updating cgminer. Can anyone shed some light, or point me towards a guide?

Assuming your S4's IP address was say 192.168.1.99:

Code:

ssh -l root 192.168.1.99 (or equivalent with putty)
wget http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
chmod +x cgminer
mv cgminer /usr/bin/cgminer
/etc/init.d/cgminer.sh restart

I think that might not keep across a power cycle though.

Installed your new binary last night on the S4 I have at home and now works great on EMC pool Cheesy

Prior to the update was averaging 1.66ths there with swing from 1.4 up to ocassionally 1.94ths with worker dif wildly swinging between 1.2k to 1.86k.

Now diff bangs around between 1.46k and 1.87k and on EMC it's averaging 1.95-2.0THs, swing is from 1.7ish up to occasionally 2.3THs. Damn fine work with the Voodoo that you do so well Wink

Now to see if it works on my other s4 that is at work. Made a backup of the working s4 and will apply it to the other one. That one never gets over 25ghs on EMC so is currently pointed at CKpool where its works perfect.
