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

[MyRig]

Yes.

If you have a thick enough cable with a strong enough PSU, 300W per hashing PCB with 1 PCI-E plug will work but if your wire is not thick enough or PSU is not strong enough to push that much electricity, then you have to use all 4 PCI-E plug

often time with cheaper/discounted PSU, you have to use all 4 PCI-E connectors!

just a quick question. is it safe to power the s5 with just 1 connector per blade?

Yeah, just make sure you use the ones nearest the ethernet port  

So they are like the S3's? No need for all 4 connections unless you'll overclock? Didn't know that.

It's not recommended, but I run a couple like that without issues - never tried OCing them though, wouldn't risk it tbh  

Edit: Good quality gauge wires are essential though.

thanks! i assume they recommend connecting all 4 is to prevent the wires from getting too hot and the connectors on the blade are in parallel

Anyone know why S5s don't failover from WestHash.com when its profitability drops below the pw parameter

Code:

stratum.WestHash.com:3334#xnsub
worker address
p=0.0113

I have six S5 and all behave fine with Westhash and Failover.

The fewer the connections, the higher the cable/connector temps and the greater the voltage drop across the cables.  When high currents are involved, always better to have more connections than fewer.

Mine seems to work fine and fails over from nicehash.com when it drops below the p= value. Which cgminer version are you using? Im running 4.9.0

Noctua NF-F12 IndustrialPPC 3000RPM PWM 120mm High Performance Fan  x 2 ( push-pool )

Conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection, the NF-F12 industrialPPC (Protected Performance Cooling) is a ruggedised high-speed version of the award-winning retail model. Thanks to the outstanding aerodynamic efficiency of the NF-F12 design and the use of a novel three-phase motor, the industrialPPC version provides superior airflow and pressure capacity while keeping noise levels and power consumption moderate as against comparable high-speed fans. While its fibre-glass reinforced polyamide construction and certified water and dust protection make the NF-F12 industrialPPC suitable for operation in challenging environments, the renowned SSO2 bearing technology guarantees an MTBF of over 150,000hrs. Topped off with Noctua's trusted reliability and six year manufacturer's warranty, the NF-F12 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability

Features:
- Based on the award-winning NF-F12 design
- 3000rpm PWM industrialPPC version
- Three-phase motor design
- Fibre-glass reinforced polyamide construction
- Certified IP52 water and dust protection
- Integrated Anti-Vibration Pads
- Six year warranty

Specification:
- Size: 120x120x25 mm
- Connector: 4-pin PWM
- Bearing: SSO2
- Blade Geometry: Heptaperf
- Frame Technology: FocusedFlow
- Rotational Speed (± 10%): 3000 RPM
- Airflow: 109.8 CFM
- Acoustical Noise: 43.5 dB(A)
- Static Pressure: 7.63 mm H2O
- Max. Input Power: 3.6 W
- Max. Input Current   : 0.3 A

JUST PERFECT!

Fan mod
1. Thermalright 130CFM pull - fan is PWM but run with blue wire hack, aka full pelt)
2. Stock S3 fan running on PWM - push

This is a strange setup, during the day when it is a bit warmer, the push fan (stock S3) runs at higher RPM (3600 max I've seen) and I get temps of 44 and 46.
Freq 412.5

wow awesome freq with very low temps
ho much power to do it?

I use 2 550W Dell server PSU's, one for each blade.

[Xian01]

Interesting. Batch Five is now sold out.

Nope, batch 5 is now / still available ...

I saw that. Interesting that price is staying firm @ $340. Still looking forward to an S2->S6 upgrade kit if it ever becomes available. Alternately, looking for at least another couple S5's to tinker with, but the current price @ $340 USD is not a rational decision for me.

TBH, the last few times I've felt like pulling the trigger on buying S5's, I ended up purchasing the equivalent USD as BTC on Coinbase instead.

Still have my jimmies all rustled from their B5 $320 initial offering shenanigans ...

great..
i will try it on my s5.
did you mod the bitmain-voltage in cgminer.conf?

No I have not and it is running on the default voltage setting, but now that you mention it (and I am sure I have adequate power and cooling), I'll look into changing / setting different voltages.

[bgibso01]

Bitmain, how about some coupons so I can buy some more S5 units now that you have them back in stock?  Maybe just 4?

we all want some coupons  bitmain has not cracked and given many out.

I believe I have the latest FW update (Wed Jan 7 14:05:02 CST 2015) in all my S5s and they run 4.8.0 cgminer. I don't know how to get it to run 4.9 but 4.8 has extranonce support.

If WestHash is paying below my p-value when I cold boot it runs pool 2 fine. Then later if WestHash pays higher than p it switches. But, when the payout drops below p it stops mining and does not failover to pool 2. The only way I can get it to hash again is to manually edit pool 2 to be pool 1. My SP20s failover whenever pool1 is dead and swicth back to pool 1 when it goes live. Hopefully bitmain will fix the bug soon.

[Subw]

its a bug in 4.8.0

And when the push stock S3 fan ramps up to 3600 rpm .... (first time I've noticed it at night!) temps fall to 40, 43

Anyone handy with fixing these. I just listed my 2Ths S4 on ebay starting at $49 (no reserve). Does need some sort of repair.

Please ship to Canada. I will bid on it if you will. If I win, I will pay the shipping via UPS and be responsible for duties and taxes on my end upon receipt. My eBay Account is 100% and older than dirt. Same as my PayPal. They are both probably older than some of the people posting on here

I remember when pay pal and Ebay first started i had a account on both of them lost that info for those accounts a long time ago  and just reopened two new accounts on Ebay and pay pal a year or two ago because then i had no use for either then now i use them more then any account, i have ever had ..


i love it on ebay when I'm told your account is not that old etc little do they know i was one of the very first ever to join either, when it went live way back,when the internet was dial up.

Yep I have been there from the early days. Used them both for forever. I stopped being a seller in eBay though. Got tired of the bullshit from eBay. I value my perfect rating hence I why I stopped selling! In all of my years I have only been ripped off once.

I want to buy s5 how the cost of shipping to Indonesia, I saw on the website was not found, please help
thank you

You can see it during checkout.
