Topic: [Guide] Dogie's Comprehensive Bitmain Antminer S3 Setup [HD] - page 28. (Read 137874 times)

Great post... thanks! 

Is it possible to power two Antminer S3's with a single PSU?
 
If so, which unit would you buy for that purpose?

If I am not over-clocking is there an advantage to using all 4 PCI-e connections, instead of just 2, on an S3?   

your 400W is likely spread across 12V, 5V, 3.3V so that 12V is actually only ~300W.  If it has two rails, 150W may be for the motherboard cable and only 150W over PCIe
on top of that, you should not load PSUs past 80% for 24/7 operation like bitcoin mining. It reduces efficiency and cheaper models will burn out within months

I have the same question, I have a bunch 400w UL certified power supply can I just use one for each miner?

From my understanding the bronze to gold level is the efficiency of power draw from the outlet but they all should deliver the rated power? IE 400W power supply should deliver 400W ?

Alright. Thank you. I just have one more question. Why do I need a 750W PSU if the miner only uses about 350W? Wouldn't getting a 500W  Corsair PSU make more sense?

That is all the hardware you need. You also need a pool account for connecting your miner and mining on. The setup for the S3 is very simple.

I don't have the hex values for non standard frequencies and I wouldn't really try them. I would wait until we know more about the stability of the S3s first.

Hey dogie. This tutorial looks incredibly useful, thank you so much for creating it! I am new to Bitcoin mining, so I just want to get this straight. If I buy the Antminer S3 and the PSU (this one: http://www.amazon.com/gp/product/B00ALK3KEM/ref=ox_sc_act_image_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER) I will be good to go, right? I will just need to connect the S3 to the PSU and an ethernet cable. I am really sorry about my lack of knowledge, but please have patience for me. I will do my best to find out more and more about Bitcoin mining.

Is there a picture?  Is there a connector on one of the hashing boards on the large heat sink side?

Goxed has a thread on over/under clocking

Internal cables...

Dogie, do you have instructions on how to change the frequency?  Seeing reports they're running better at 212.5. 

Thanks in advance, appreciate the great guides. 

How does the control board get power?
