ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[fr4nkthetank]

Hi guys.

can i beg a coupon off anyone?  i've given a bunch for the s1 way back when

[dissolution]

Very cool dart. Must have taken some work to set that up.

Next you could measure Wattage, and BTC value and graph profitability over time

[Rabinovitch]

For the S5 what is the recommended worker difficulty. I have been using 2048. Is that high enough?

1024 should be good enough. 2048 is probably too high.

If there are no rejected or/and stale shares, then why not to use 2048?..

Stock fan produces ~69db, which is not typically tolerable in the house (apart from basement, attic, garage, shed)
Fan play to have as much hash as possible while maintaing low dB:
~30C ambient
1. Noctua 3000 PWM ($24.5, 110CFM, up to 3000rpm, just 41dB) in push position: ~59-61C at 325mhz, 1070Gh; less stable at 350mhz.
2. Scythe Ultra KAZE ($15.3, 130CFM, 3000rpm, 46dB) in push position via molex adapter-worse than Noctua, temp rising close to 65C at 325mhz, discontinued. Strange result as this fan has nominally higher CFM than Noctua.
3. Noctua in push, Scythe in pull (connected to molex through included adapter), up to 337.5 mhz is stable (1100 Gh).

Conclusion: adding Scythe ($15) in pull might be not worth it as it adds just ~30gh.
I simply taped Scythe to exhaust in pull orientation because could not find proper screws yet.

Question: anybody knows what are the characteristics/dimensions of the machine screws Bitmain is using for fans? They seem to be in between 3 and 4mmX42mm, but I wasn't able to find such screws easily. They are not 3X40mm for sure. Anybody have a link?

I simply taped Scythe to back because could not find proper screws yet.

Out of curiosity, what weighting did you use when you measured the SPL of the fans?

what is SPL? I am not familiar with this term.

Sound pressure level. It's the dBs you got.

stock I measured with iPhone app at 1m distance, cannot do the same with Noctua and Scythe because I have other miners (SP20) in the same room, so I used numbers from the tech description and/or Amazon description.

Use two of the stock screws from the front on the back but with zip ties around the threads by the head. One tie on each should give you enough space so the blades of the fan do not rub anymore.

What's the recommended power supply for an S5?

[MyRig]

EVGA 1300 for 2 S5 or EVGA 1000 for 1 S5

What's the recommended power supply for an S5?

What's the recommended power supply for an S5?

If you're running a pair - hard to find anything better than EVGA 1300 G2.
For as single one you could use another trusted workhorse Corsair CX750 but its PCI-E connectors are in bundled two pairs, so you end up running 300W on one set of wires... probably a bit risky.
I'm using this one - four separate PCI-E, works well: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182133

If noise is not an issue and you don't want to invest in an ATX PSU look for used server power supplies on eBay, but you'll need some accessories. Search around these forums, there's plenty of advice on going this route.

Can I run 1 S5 on a 650W EVGA?

Yes, but not recommended. The power consumption is about 600watt. I am not sure if the psu will be able to run at such load 24/7 for long time.

Wondering why I have not received tracking on batch 4 yet?  Anybody get tracking yet, they were to ship out on the 12th.

You can go to UPS and track by reference using your order number. Mine is on the way, just no emails from Bitmain and no update of status on their website.

Is the order number the PO number? Mine is still not shown as shipped, confirmed payment on 1/9.

I didn't need to use the order number as I have a "My UPS " account and as soon as I logged on it shows all shipments coming my way. Its a free account and allows you to change delivery also.

Hi, the Order ID is start with 00120…… 32 letters. Please PM me the order ID, and I will check the order status for you.

EVGA 1300 for 2 S5 or EVGA 1000 for 1 S5

What's the recommended power supply for an S5?

I am using HP 575W server power supply, it is small and efficient. I run at 381.5MHz producing  1.25Th/s

[BITMAIN_Kiddy]

Did anyone noticed bitmain have increased shipping costs for S5 (was like 50 and now it is 80)

Hi, the shipping cost will be automatically calculated by the system when you place the order in our official website.

Hi, the screw we're using for fans is PM4*42.

[bbxx]

i got declared value of 2 s5 896$
it is 130$ more than i paid to bitmain

i will have to pay 3% customs fee and 23% vat on top of it
so i will overpay 35$ due to bitmain error

can i get this money back ?

thanks
